5 Mistakes Companies Make When Retiring IT Equipment (and How to Avoid Them)

May 22, 2025 at 7:14 pm by Amanda Canale

As technology evolves at a relentless pace, organizations are continually refreshing their IT infrastructure to stay competitive, secure, and efficient. But with the excitement of onboarding new systems comes a less glamorous yet equally critical task—retiring outdated IT equipment. This phase is often overlooked or rushed, leading to significant security, compliance, and environmental risks. Retiring IT assets isn’t just about unplugging and discarding them; it requires a thoughtful, documented, and secure process.

Here are five common mistakes companies make when retiring IT equipment, and how to avoid them.

Assuming Data Is Gone After Deletion

Perhaps the most pervasive and dangerous misconception is that data is permanently erased simply by deleting files or formatting hard drives. In reality, deletion simply removes the pointers to data, not the actual data itself. Without proper data sanitization protocols, sensitive corporate or customer information can still be recovered using forensic tools—even from devices that appear “clean.”

To prevent this, organizations must implement certified data destruction processes that meet or exceed standards such as NIST 800-88 or NSA, depending on the industry and classification of the data being destroyed. This can involve physical destruction, such as shredding, crushing, or disintegrating, and degaussing. However, if the drive contains classified information, it should be degaussed then physically destroyed, per the NSA. This two-way destruction method ensures complete and total obliteration.

Proper documentation should include both the data’s chain of custody and the destruction process. It’s also important to retain certificates of destruction for auditing purposes. Relying on basic deletion is a gamble no organization should take, especially with data privacy regulations tightening worldwide.

Overlooking Nontraditional Data Sources

When thinking about data-bearing equipment, organizations typically focus on obvious items like servers, desktops, or laptops. However, nontraditional data sources often fall through the cracks. Devices such as printers, copiers, VoIP phones, network switches, external hard drives, and even smart devices can store sensitive configuration data, credentials, or internal communications.

The root cause of this oversight is often a lack of a comprehensive IT asset inventory. Without knowing exactly what equipment exists and what data it might contain, companies risk leaving information behind during decommissioning. Creating and maintaining a detailed asset inventory—updated continuously throughout the hardware lifecycle—is essential. It allows for thorough tracking and ensures every device is accounted for, assessed for data sensitivity, and handled properly during retirement.

Not Verifying E-Waste Recyclers

Environmental responsibility is an increasingly important part of corporate social governance, and most businesses strive to dispose of retired IT assets through recycling partners. However, not all e-waste recyclers operate ethically or securely. Some may claim to responsibly dispose of electronics but instead export hazardous waste to developing countries or improperly dispose of data-bearing devices, creating significant brand and legal risks.

Due diligence is critical when selecting a recycling partner. Look for certifications such as R2 (Responsible Recycling) or e-Stewards, which ensure adherence to high environmental and data security standards. Auditing the recycler’s practices, requesting references, and visiting their facilities when possible can also help verify their legitimacy. Partnering with a reputable recycler protects both your company’s reputation and the planet.

Delaying Decommissioning

Outdated or unused IT assets often sit idle in storage closets, server rooms, or even employee homes for extended periods. This delay in decommissioning can create a host of problems. Unsecured, unused devices are prime targets for data breaches, theft, or accidental loss. Additionally, without a timely and consistent retirement process, organizations lose visibility into asset status, which can create confusion, non-compliance, or unnecessary costs (like continued software licensing or maintenance).

The best way to address this is by implementing in-house destruction solutions as an integrated part of the IT lifecycle. Rather than relying on external vendors or waiting until large volumes of devices pile up, organizations can equip themselves with high security data destruction machinery—such as hard drive shredders, degaussers, crushers, or disintegrators—designed to render data irretrievable on demand. This allows for immediate, on-site sanitization and physical destruction as soon as devices are decommissioned. Not only does this improve data control and reduce risk exposure, but it also simplifies chain-of-custody tracking by eliminating unnecessary handoffs. With in-house destruction capabilities, organizations can securely retire equipment at the pace their operations demand—no waiting, no outsourcing, and no compromise.

Failing to Establish a Chain of Custody and Involve Compliance Teams

Retiring IT equipment isn’t just a logistical or technical task—it’s also a matter of governance and accountability. Many organizations fail to establish a documented chain of custody when IT assets are moved, stored, or handed off to third-party vendors. This lack of visibility and traceability increases the risk of data loss, theft, or mishandling.

Furthermore, failure to involve compliance, legal, and security teams in the decommissioning process can lead to overlooked regulatory obligations or missteps. In industries governed by HIPAA, GDPR, PCI-DSS, or similar regulations, improper data disposal can result in hefty fines and reputational damage. In the government sector, improper disposal can result in far worse scenarios, such as the leak of classified national secrets.

To avoid this pitfall, organizations must formalize their decommissioning policies and workflows. This includes tagging each asset, tracking its movement through every stage of decommissioning, and involving all relevant stakeholders. A documented chain of custody ensures accountability and supports audits or investigations, should they arise. Including compliance and security teams in the planning stages helps identify applicable regulations and ensures proper adherence from start to finish.

Why In-House, High-Security Data Destruction Matters More Than Ever

All of the above mistakes share a common theme: a lack of control. The more hands data passes through, the higher the risk of exposure. That’s why in-house high-security data destruction is not only a best practice—it’s becoming a necessity.

By investing in high security data destruction solutions that are designed specifically for in-house data destruction, companies maintain full custody of their data from start to finish. Physical destruction solutions such as NSA/CSS-listed disintegrators, degaussers, and hard drive shredders allow businesses to render data unrecoverable before any asset leaves the premises. This eliminates the reliance on third-party vendors, reduces the risk of chain-of-custody failure, and reinforces compliance with the most stringent data protection regulations.

Moreover, in-house solutions offer operational flexibility and peace of mind. Assets can be destroyed immediately, in a controlled environment, by trained staff—ensuring sensitive data never leaves corporate oversight. For sectors like defense, healthcare, finance, and critical infrastructure, this level of control isn’t just helpful—it’s essential.

Organizations that take data destruction seriously are recognizing that outsourced convenience doesn’t always equal security. As threats to information security become more sophisticated, the safeguards must follow suit. Security Engineered Machinery’s (SEM) data destruction equipment is a proactive investment in compliance, reputation, and operational integrity.

In the end, how an organization disposes of its IT assets says just as much about its values as how it deploys them. When the goal is to protect data at every stage of its lifecycle, the most secure option is the one that never lets it out of your sight.

ISO 27001: Achieving Data Security Standards for Data Centers

March 19, 2025 at 4:50 pm by Amanda Canale

In today’s digital world, data is more than just an asset—it’s the lifeblood of every business and organization. From customer information to proprietary research, organizations rely on data to drive operations, inform decision-making, and maintain competitive advantages. But as the volume of sensitive data grows, so do the risks. Data breaches, cyberattacks, and unauthorized access can have catastrophic consequences for organizations, both on a financial and reputation level. To address these increasing concerns, ISO 27001 provides a comprehensive framework for managing information security within businesses and organizations, and it is especially crucial for data centers. This internationally recognized standard helps organizations safeguard sensitive data by outlining systematic processes for implementing, monitoring, reviewing, and improving information security management practices.

Understanding ISO 27001 and Its Importance for Data Centers

The International Organization for Standardization (ISO), a global non-governmental organization, developed an international standard known as ISO 27001. This standard helps organizations establish, implement, and maintain an Information Security Management System (ISMS) and provides a structured approach to managing sensitive company information, ensuring its confidentiality, integrity, and availability. Data centers, which handle vast amounts of sensitive data, are particularly vulnerable to security breaches and threats. As the so-called custodians of this valuable asset, data centers must ensure their security practices are robust, adaptable, and up to the standards required by clients, regulatory bodies (such as the NSA), and industry best practices. ISO 27001 serves as a vital standard in meeting these objectives.

The beauty of ISO 27001 lies in its comprehensive scope. It ensures data centers implement policies, procedures, and controls across various areas, from risk assessment and access control to physical security and monitoring for potential threats. What’s more, this isn’t a one-time setup. The standard requires ongoing reviews and updates to ensure security measures evolve with emerging risks, regulatory changes, and technological advancements.

For data centers, ISO 27001 isn’t just a certification—it’s a proactive, ongoing effort to identify, address, and mitigate risks that could threaten the integrity of their operations and the security of their clients’ data.

The Certification Process: Steps Toward ISO 27001 Compliance

Achieving ISO 27001 certification is not an overnight process. It’s a journey that requires commitment, resources, and a structured approach in order to align the organization’s information security practices with the standard’s requirements.

The first step in the process is conducting a comprehensive risk assessment. This assessment involves identifying potential security risks and vulnerabilities in the data center’s infrastructure and understanding the impact these risks might have on business operations. This forms the foundation for the ISMS and determines which security controls are necessary.

Once the risks have been identified, data centers must develop policies, procedures, and protocols that address each of the identified risks. These policies cover a wide range of security aspects, including access control, data encryption, incident response, and employee training. It is crucial that these policies be tailored to the unique needs of the data center and its operations.

After developing the necessary documentation, the data center must implement the ISMS and ensure it is functioning as intended. This involves securing the infrastructure, enforcing security protocols, and ensuring that employees and contractors follow the established security practices. Following the implementation of the ISMS, an independent external auditor will typically assess the data center’s adherence to the ISO 27001 standard. If the data center meets the requirements, certification will be awarded.

It is important to note that obtaining ISO 27001 certification is not a one-time achievement. Maintaining compliance requires ongoing efforts, including regular internal audits and continual monitoring to ensure that security controls are effective and up to date. Changes to the data center’s operations or the emergence of new risks may necessitate adjustments to the ISMS to keep it relevant and effective.

ISO 27001 and Risk Mitigation: Enhancing Security Posture

One of the key benefits of ISO 27001 is its focus on risk management. Rather than simply reacting to security incidents, ISO 27001 promotes a proactive approach that helps data centers identify, assess, and address security risks before they lead to both external threats (cyberattacks or natural disasters) and internal risks (employee negligence or system failures). By addressing these risks early, they can reduce the likelihood of incidents and minimize the damage if one does occur.

The standard also emphasizes the importance of continual improvement. ISO 27001 requires data centers to regularly review and update their ISMS to ensure it remains effective in the face of new threats and challenges. This iterative cycle of monitoring, reviewing, and refining security practices ensures that data centers can stay ahead of emerging risks and respond effectively to changes in the threat landscape. As a result, ISO 27001 helps organizations build a more resilient security posture that can adapt to changing conditions.

The Role of Data Destruction in ISO 27001 Compliance

A crucial, yet often overlooked, aspect of ISO 27001 compliance is the proper destruction of data. Data centers are responsible for managing vast amounts of sensitive information and ensuring that data is securely sanitized when it is no longer needed is a critical component of maintaining information security. Improper data disposal can lead to serious security risks, including unauthorized access to confidential information and data breaches.

At Security Engineered Machinery, we understand that the secure destruction of data is not just a best practice—it’s a critical responsibility. Whether it’s personal information, financial records, intellectual property, or any other type of sensitive data, the potential risks of improper disposal are too great to ignore. Data breaches and unauthorized access can result in significant financial loss, legal liabilities, and reputational damage. That’s why we emphasize the importance of high-security data destruction, ensuring that no trace of sensitive information remains accessible, regardless of the format or storage medium.

ISO 27001 addresses this same concern by establishing strict guidelines for data destruction. According to the standard, data must be securely destroyed when it is no longer required for business purposes, and it must be done in a way that prevents unauthorized recovery. This is particularly important for data centers, which handle large volumes of information, much of which may be confidential, personally identifiable, or subject to regulatory controls.

The process of data destruction can take several forms, depending on the nature of the data and the storage medium. Physical destruction (such as shredding or crushing hard drives) and degaussing are common methods used to ensure data is irretrievably decommissioned. ISO 27001 requires that data destruction be handled in a manner that meets the highest security standards, reducing the risk of data leaks or exposure. At SEM, we believe that physical destruction, when met with the degaussing for rotational hard drives storing sensitive or classified information, is the best method.

In addition to mitigating security risks, proper data destruction also helps data centers comply with legal and regulatory requirements. Many jurisdictions have strict data retention and privacy laws that mandate secure data disposal practices, particularly when it comes to personally identifiable information (PII) or financial data. By following ISO 27001’s data destruction guidelines, data centers can reduce their liability and avoid potential legal consequences.

Conclusion: The Value of ISO 27001 for Data Centers

ISO 27001 is a comprehensive and effective framework for managing information security risks within data centers. It offers a structured approach to identifying, mitigating, and monitoring security threats, helping organizations maintain a secure environment for the vast amounts of sensitive data they handle. Certification demonstrates a data center’s commitment to protecting the confidentiality, integrity, and availability of client data, enhancing its reputation and instilling trust among customers and partners.

Achieving and maintaining ISO 27001 certification requires ongoing effort and attention, but the benefits far outweigh the costs. Not only does it help mitigate risks and improve overall security posture, but it also establishes clear protocols for secure data destruction, reducing the risk of data breaches and legal liabilities. Ultimately, ISO 27001 provides data centers with the tools they need to enhance their security practices, stay ahead of emerging threats, and continue operating in an increasingly complex and risk-laden digital world.

 

The Critical Imperative of Data Center Physical Security

September 12, 2023 at 8:00 am by Amanda Canale

In our data-driven world, data centers serve as the backbone of the digital revolution. They house an immense amount of sensitive information critical to organizations, ranging from financial records to personal data. Ensuring the physical security of data centers is of paramount importance. After all, a data center’s physical property is the first level of security. By meeting the ever-evolving security mandates and controlling access to the premises, while maintaining and documenting a chain of custody during data decommissioning, data centers ensure that only authorized personnel have the privilege to interact with and access systems and their sensitive information.

Levels of Security Within Data Centers

Before any discussion on physical security best practices for data centers can begin, it’s important to think of data center security as a multi-layered endeavor, with each level meticulously designed to strengthen the protection of data against potential breaches and unauthorized access. 

Data centers with multi-level security measures, like Google and their six levels of data center security, represent the pinnacle of data infrastructure sophistication. These facilities are designed to provide an exceptional level of reliability and high security, offering the utmost advances in modern day security, ensuring data remains available, secure, and accessible. 

Below we have briefly broken down each security level to offer an inside peek at Google’s advanced security levels and best practices, as they serve as a great framework for data centers. 

  • Level 1: Physical property surrounding the facility, including gates, fences, and other more significant forms of defenses.
  • Level 2: Secure perimeter, complete with 24/7 security staff, smart fencing, surveillance cameras, and other perimeter defense systems.
  • Level 3: Data center entry is only accessible with a combination of company-issued ID badges, iris and facial scans, and other identification-confirming methods.
  • Level 4: The security operations center (SOC) houses the facility’s entire surveillance and monitoring systems and is typically managed by a select group of security personnel.
  • Level 5: The data center floor only allows access to a small percentage of facility staff, typically made up solely of engineers and technicians.
  • Level 6: Secure, in-house data destruction happens in the final level and serves as the end-of-life data’s final stop in its chain of custody. In this level, there is typically a secure two-way access system to ensure all end-of-life data is properly destroyed, does not leave the facility, and is only handled by staff with the highest level of clearance.

As technology continues to advance, we can expect data centers to evolve further, setting new, intricate, and more secure standards for data management in the digital age.

Now that you have this general overview of best practices, let’s dive deeper.

Key Elements of Data Center Physical Security

Effective data center physical security involves a combination of policies, procedures, and technologies. Let’s focus on five main elements today:

  • Physical barriers
  • Surveillance and monitoring
  • Access controls and visitor management
  • Environmental controls
  • Secure in-house data decommissioning
Physical Barriers

Regardless of the type of data center and industry, the first level of security is the physical property boundaries surrounding the facility. These property boundaries can range widely but typically include a cocktail of signage, fencing, reinforced doors, walls, and other significant forms of perimeter defenses that are meant to deter, discourage, or delay any unauthorized entry.  

Physical security within data centers is not a mere addendum to cybersecurity; it is an integral component in ensuring the continued operation, reputation, and success of the organizations that rely on your data center to safeguard their most valuable assets.

Surveillance and Monitoring

Data centers store vast amounts of sensitive information, making them prime targets for cybercriminals and physical intruders. Surveillance and monitoring systems are the vigilant watchdogs of data centers and act as a critical line of defense against unauthorized access. High-definition surveillance and CCTV cameras, alarm systems, and motion detectors work in harmony to help deter potential threats and provide real-time alerts, enabling prompt action to mitigate security breaches.

Access Controls and Visitor Management

Not all entrants are employees or authorized visitors. Access controls go hand-in-hand with surveillance and monitoring; both methods ensure that only authorized personnel can enter the facility. Control methods include biometric authentication, key cards, PINs, and other secure methods that help verify the identity of individuals seeking entry. These controls, paired with visitor management systems, allow facilities to control who may enter the facility, and allows staff to maintain logs and escort policies to track the movements of guests and service personnel. These efforts minimize the risk of unauthorized access, and by preventing unauthorized access, access controls significantly reduce the risk of security breaches.

Under the umbrella of access controls and visitor management is another crucial step in ensuring that only authorized persons have access to the data: assigning and maintaining a chain of custody. 

But what exactly is a chain of custody?

A chain of custody is a documented trail that meticulously records the handling, movement, and access, and activity to data. In the context of data centers, it refers to the tracking and documenting of data assets as they move within the facility, and throughout their lifecycle. A robust chain of custody ensures that data is always handled only by authorized personnel. Every interaction with the data, whether it’s during maintenance, migration, backup, or destruction, is documented. This transparency greatly reduces the risk of unauthorized access or tampering, enhancing overall data security and helps maintain data integrity, security, and compliance with regulations.

Environmental Controls

Within the walls of data centers, a crucial aspect of safeguarding your digital assets lies in environmental controls, so facilities must not only fend off human threats but environmental hazards, as well. As unpredictable as fires, floods, and extreme temperatures can be, data centers must implement robust environmental control systems as they are essential in preventing equipment damage and data loss. 

Environmental control systems include, but are not limited to:

  • Advanced fire suppression systems to extinguish fires quickly while minimizing damage to both equipment and data.
  • Uninterruptible power supplies (UPS) and generators ensure continuous operation even in the face of electrical disruptions.
  • Advanced air filtration and purification systems mitigate dust and contaminants that can harm your equipment, keeping your servers and equipment uncompromised. 
  • Leak detection systems are crucial for any data center. They are designed to identify even the smallest amount of leaks and trigger immediate responses to prevent further damage.

These systems are the unsung heroes, ensuring the optimal conditions for your data to (securely) thrive and seamlessly integrate with physical security measures.

In-House Data Decommissioning

While there’s often a strong emphasis on data collection and storage (rightfully so), an equally vital aspect in data center security is often overlooked—data decommissioning. In-house data decommissioning is the process of securely and responsibly disposing of any data considered “end-of-life,” ultimately empowers organizations to maintain better control over their data assets. Simply put, this translates to the physical destruction of any media that is deemed end-of-life by way of crushing for hard disk drives (HDDs), shredding for paper and solid state drives (SSDs), and more. 

When data is properly managed and disposed of, organizations can more effectively enforce data retention policies, ensuring that only relevant and up-to-date information is retained. This, in turn, leads to improved data governance and reduces the risk of unauthorized access to sensitive data.

In-house data decommissioning ensures that sensitive data is disposed of properly, reducing the risk of data leaks or breaches. It also helps organizations comply with data privacy regulations such as GDPR and HIPAA, which often require stringent secure data disposal practices.

Physical Security Compliance Regulations

We understand that not all compliance regulations are a one-size-fits-all solution for your data center’s security needs. However, the following regulations can still offer invaluable insights and a robust cybersecurity framework to follow, regardless of your specific industry or requirements. 

ISO 27001: Information Security Management System (ISMS)

ISO 27001 is an internationally recognized standard that encompasses a holistic approach to information security. This compliance regulation covers aspects such as physical security, personnel training, risk management, and incident response, ensuring a comprehensive security framework.

When it comes to physical security, ISO 27001 provides a roadmap for implementing stringent access controls, including role-based permissions, multi-factor authentication, and visitor management systems, and the implementation of surveillance systems, intrusion detection, and perimeter security. Combined, these controls help data centers ensure that only authorized personnel can enter the facility and access sensitive areas. 

Data centers that adopt ISO 27001 create a robust framework for identifying, assessing, and mitigating security risks. 

ISO 27002: Information Security, Cybersecurity, and Privacy Protection – Information Security Controls

ISO 27002 offers guidelines and best practices to help organizations establish, implement, maintain, and continually improve an information security management system, or ISMS. While ISO 27001 defines the requirements for an ISMS, ISO 27002 provides the practical controls for data centers and organizations to implement so various information security risks can be addressed. (It’s important to note that an organization can be certified in ISO 27001, but not in ISO 27002 as it simply serves as a guide. 

While ISO 27002’s focus is not solely on physical security, this comprehensive practice emphasizes the importance of conducting thorough risk assessments to identify vulnerabilities and potential threats in data centers, which can include physical threats just as much as cyber ones. Since data centers house sensitive hardware, software, and infrastructure, they are already a major target for breaches and attacks. ISO 27002 provides detailed guidelines for implementing physical security controls, including access restrictions, surveillance systems, perimeter security and vitality of biometric authentication, security badges, and restricted entry points, to prevent those attacks.

Conclusion

In an increasingly digital world where data is often considered the new currency, data centers serve as the fortresses that safeguard the invaluable assets of organizations. While we often associate data security with firewalls, encryption, and cyber threats, it’s imperative not to overlook the significance of physical security within these data fortresses. 

By assessing risks associated with physical security, environmental factors, and access controls, data center operators can take proactive measures to mitigate said risks. These measures greatly aid data centers in preventing unauthorized access, which can lead to data theft, service disruptions, and financial losses. Additionally, failing to meet compliance regulations can result in severe legal consequences and damage to an organization’s reputation.

In a perfect world, simply implementing iron-clad physical barriers and adhering to compliance regulations would completely eliminate the risk of data breaches. Unfortunately, that’s simply not the case. Both data center security and compliance encompass not only both cybersecurity and physical security, but secure data sanitization and destruction as well. The best way to achieve that level of security is with an in-house destruction plan. 

In-house data decommissioning allows organizations to implement and enforce customized security measures that align with their individual security policies and industry regulations. When data decommissioning is outsourced, there’s a risk that the third-party vendor may not handle the data with the same level of care and diligence as in-house teams would.

Throughout this blog, we’ve briefly mentioned that data centers should implement a chain of custody, especially during decommissioning. In-house data decommissioning and implementing a data chain of custody provide data centers the highest levels of control, customization, and security, making it the preferred choice for organizations that prioritize data protection, compliance, and risk mitigation. By keeping data decommissioning within their own control, organizations can ensure that their sensitive information is handled with the utmost care and security throughout its lifecycle.

At SEM, we have a wide range of data center solutions designed for you to securely destroy any and all sensitive information your data center is storing, including the SEM iWitness Media Tracking System and the Model DC-S1-3. 

The iWitness is a tool used in end-of-life data destruction to document the data’s chain of custody and a slew of crucial details during the decommissioning process. The hand-held device reports the drive’s serial number, model and manufacturer, the method of destruction and tool used, the name of the operator, date of destruction, and more, all easily exported into one CSV file. 

The DC-S1-3 is specifically designed for data centers to destroy enterprise rotational/magnetic drives and solid state drives. This state-of-the-art solution uses specially designed saw tooth hook cutters to shred those end-of-life rotational hard drives to a consistent 1.5″ particle size. This solution is available in three configurations: HDD, SSD, and a HDD/SSD Combo. The DC-S1-3 series is ideal for the shredding of HDDs, SSDs, data tapes, cell phones, smartphones, optical media, PCBs, and other related electronic storage media. 

The consequences of improper data destruction are endless, and statute of limitations don’t apply to data breaches. No matter what the industry, purchasing in-house, end-of-life data destruction equipment is well worth the investment. This can in turn potentially save your data center more time and money in the long run by preventing breaches early on.

Data Centers and NIST Compliance: Why 800-53 is Just the Start

August 22, 2023 at 4:42 pm by Amanda Canale

The world of data storage has been exponentially growing for the past several years and shows no signs of slowing down. From paper to floppy disks, HDDs to SSDs, and large servers to cloud-based infrastructures, the way we store data has become increasingly intricate using the latest and greatest major technological advancements. 

As the way we store our data continues to evolve, it’s becoming increasingly vital for data centers, federal agencies, and organizations alike to implement proper and secure data cybersecurity and information security practices, and appropriate procedures for secure data sanitization and destruction. Data center compliance is essential for various reasons, primarily centered around ensuring the security, integrity, and reliability of their data and systems. By complying with industry standards and regulations, data centers can safeguard sensitive data and ensure that proper security measures are in place to prevent unauthorized access, data breaches, and cyberattacks – both while data storage devices are in use and when they reach end-of-life. 

In summary, data center compliance falls under both cybersecurity and physical security best practices, and secure data sanitization and destruction. For a data center to operate at optimal performance and security, one cannot be without the other.

When discussing data center compliance, it’s important to not leave out an important player: the National Institute of Standards and Technology (NIST). NIST is one of the most widely recognized and adopted cybersecurity frameworks, is the industry’s most comprehensive and in-depth set of framework controls, and is a non-regulatory federal agency. NIST’s mission is to educate citizens on information system security for all applications outside of national security, including industry, government, academia, and healthcare on both a national and global scale. 

Their strict and robust standards and guidelines are widely recognized and adopted by both data centers and government entities alike seeking to improve their processes, quality, and security. 

In today’s blog, I want to dive into the two most important NIST publications data centers should consistently reference and implement into their security practices: NIST 800-88 and NIST 800-53. Both standardizations help create consistency across the industry, allowing data centers to communicate and collaborate with, and more effectively protect partners, clients, and regulatory bodies. Again: cybersecurity and destruction best practices go hand-in-hand, and should be implemented as a pair in order for a data center to operate compliantly. 

Step 1: Data Center Security and Privacy Framework

NIST 800-53

NIST 800-53 provides guidelines and recommendations for selecting and specifying security and privacy controls for federal information systems and organizations. While NIST 800-53 is primarily utilized by federal agencies, its principles and controls are widely recognized and adopted as a critical resource for information security and privacy management, not only by federal agencies but also by private sector organizations, international entities, and more importantly, data centers. 

NIST 800-53 serves as a comprehensive catalog of security and privacy controls that data centers can use to design, implement, and assess the security posture of their IT systems and infrastructure, all of which are crucial in sustaining a data center. The controls are related to data protection, encryption, data retention, and data disposal, and serve as a valuable resource for data centers looking to establish intricate and well-rounded cybersecurity and information security programs. 

NIST 800-53 addresses various aspects of information security, such as access control, incident response, system and communications protection, security assessment, and more. Each control is paired with specific guidelines and implementation details. These security controls, of which there are over a thousand, are further categorized into twenty “control families” based on their common objectives. (For example, access control controls are grouped together, as are incident response controls, and so forth.) These control families cover various aspects of security, including access control, network security, system monitoring, incident response, and more, offering data centers much higher rates of uptime and ability to minimize downtime.

Since data centers often handle sensitive and valuable information, they require robust physical security measures to prevent breaches and unauthorized access. NIST 800-53 addresses physical security controls, including access controls, video surveillance, intrusion detection systems, and environmental monitoring, which are vital in protecting the data center’s infrastructure.

It’s important to mention that while NIST 800-53 provides an increasingly valuable foundation for securing data center operations, organizations may need to tailor the controls to their specific environments, risk profiles, and compliance requirements. NIST 800-53 offers a flexible framework that allows for customization to suit the unique needs of different data center operators, making it a vital and critical resource.

Step 2: Data Destruction Compliance 

NIST 800-88

First published in 2006, NIST 800-88 and its Guidelines for Media Sanitization provides guidance and regulations on how citizens can conduct the secure and proper sanitization and/or destruction of media containing sensitive, classified, and top secret information. NIST 800-88 covers various types of media, including hard drives (HDDs), solid-state drives (SSDs), magnetic tapes, optical media, and other media storage devices. NIST 800-88 has quickly become the utmost standard for the U.S. Government and has been continuously referenced in federal data privacy laws. More so, NIST 800-88 regulations have been increasingly adopted by private companies and organizations, especially data centers. The main objective is to help data centers and organizations establish proper procedures for sanitizing media before its disposal at end-of-life.

When a data center facility or section is being decommissioned, equipment such as servers, storage devices, and networking gear must be properly sanitized and disposed of. NIST 800-88’s guidelines help data center operators develop procedures to securely handle the removal and disposal of equipment without risking future data breaches 

When it comes to sanitizing media, NIST 800-88 offers three key methods:

  1. Clearing: The act of overwriting media with non-sensitive data to prevent data recovery.
  2. Purging: A more thorough and comprehensive method that will render the stored data unrecoverable using advanced technology, such as cryptographic erasure and block erasing.
  3. Destruction: The physical destruction of a storage device either by way of shredding, crushing, disintegrating, or incineration. This often includes electromagnetic degaussing, a method that produces a buildup of electrical energy to create a magnetic field that scrambles and breaks the drive’s binary code, rendering it completely inoperable. The strength of the degausser is critical when eliminating sensitive information from magnetic media. Typically, degaussers evaluated and listed by the National Security Agency (NSA) are considered the golden standard. 

However, even these methods can come with their own drawbacks. For instance: 

  1. Clearing: For sensitive, classified, or top secret information, clearing or overwriting should never serve as the sole destruction method. Overwriting is only applicable to HDDs, not SSDs or Flash, and does not fully remove the information from the drive. 
  2. Purging: Unfortunately, purging methods are highly prone to human error and are a very time-consuming process.
  3. Destruction: Once the drive has been destroyed, it cannot be reused or repurposed. However, this method provides the assurance and security that the data is fully unrecoverable, the process can take mere seconds, and there is no room for human error.

The chosen destruction and/or sanitization method depends on the sensitivity of the information on the media and the level of protection required, so it is crucial that data centers and organizations take into account the classification of information and media type, as well as the risk to confidentiality. NIST 800-88 provides valuable guidance on media sanitization practices, which are crucial for data centers to ensure the secure disposal of data-filled devices while minimizing the risk of data breaches. Proper implementation of NIST guidelines allows data center officials to protect sensitive information and maintain data security throughout the lifecycle of data center equipment.

The Importance of Verification 

NIST guidelines, specifically NIST 800-88, have become the industry standard when it comes to secure data sanitization; however, they are not as definitive as other regulatory compliances. With NIST, the responsibility of data sanitization falls onto data centers’ or an agency’s chief information officers, system security managers, and other related staff.

As discussed above, the destruction and/or sanitization method depends on the sensitivity of the information on the media and the level of protection required, so it is critical to the security of the end-of-life data that organizations discuss the matters of security categorization, media chain of custody including internal and external considerations, and the risk to confidentiality.

Regardless of the method chosen, verification is the next critical step in the destruction and sanitization process. NIST verification typically refers to the process of validating or verifying compliance with standards, guidelines, or protocols established by the data center and/or organization. By NIST 800-88 standards, verification is the process of testing the end-of-life media to see if the stored information is accessible. 

For sanitization equipment to be verified, it must be subjected to testing and certification, such as the NSA evaluation and listing, and must abide by a strict maintenance schedule. For proper sanitization, the device must be verified through a third party testing should the media be reused. However, when media is destroyed, no such verification is necessary, as the pulverized material itself is verification enough. 

Since third party testing can be impractical, time consuming, and a gateway to data breaches, we at SEM always push for the in-house sanitization and destruction of media as the only choice to ensure full sanitization of data and the only way to mitigate future risks. When destroying data in-house, companies can be positive that the data is successfully destroyed. 

Conclusion

When it comes to data center compliance and security, there is no one-stop-shop. Adhering to both NIST 800-88 and 800-53 guidelines enhances the reputation of data centers by demonstrating a commitment to data security and privacy. This can help build trust with clients, customers, and stakeholders, leading to stronger business relationships. More importantly, these guidelines are necessary when collecting, storing, using, or destroying certain data. NIST provides educational resources, training materials, and documentation that help data center staff understand security concepts and best practices, empowering data center personnel to implement effective security measures.
