A guide to physical security assessments

Security is one of the most important factors in the modern office. It's your first line of defense against intruders, natural disasters, and any other disruptive events that could derail your business. If you want to make it top-notch, you probably need a physical security assessment.

As the name implies, this is a comprehensive physical inspection and evaluation of every aspect of your security system, its controls, and its parameters throughout your space or facility. This is done on both an individual and a macro level, giving you the intel you need to make better decisions about how to run your facility.

Generally, the physical security risk assessment is the combined process of both practicing an intensive audit and analyzing the results that come from it, which pertains to the entire physical security system of a particular building. In order to make sure you're going about it correctly, use these tips to keep your space safer from harm.

Understanding physical security audits #

Physical security is the system of hardware, technology, and practices that protect physical assets within your space. Modern assessments need to account for both physical hardware and the digital systems that control them.

There are many kinds of threats and vulnerabilities (natural ones like fire and human ones like burglary) that can compromise the resources, assets, and sensitive information that make your business run.

The most common threats can strike either through your wireless network or through physical intrusion. Hacking into software and other internet-enabled resources is much easier if someone can physically enter your facility versus operating remotely. Because of this, your physical security needs to be active, effective, and alert.

Physical security management vs. physical security assessments #

Physical security management and physical security assessments can look similar at first glance, but they are unique in certain fundamental ways. In a physical security assessment, the availability, implementation, and maintenance of the security systems are measured, while security management often maintains a security system on a daily basis.

Security audits find the security gaps and loopholes in the existing security mechanism and then suggest fixes for specific problems. On the other hand, security management is a more regular process that keeps your system online. While both are necessary to run an effective business, auditing and assessing your physical security system is important if you want to improve the safety of your facility.

How to find physical security issues #

Physical security audits can uncover numerous problems associated with your system or your procedures. A robust security system may include numerous security controls, such as human guards, physical locks, intelligent locks, fences, a CCTV system, proper lighting, and alarms, among other components. Conducting a physical security audit shows you exactly what the security gaps in your facility are, which might mean that you have to invest in more equipment or better operational guidelines.

Operational and personnel issues #

Operational issues can take many forms, but they all have to do with the people who run your access control system.

Poor motivation, supervision, and monitoring of your space's security guards can lead to improper adherence to security policy procedures.

Low levels of precaution and care about your valuable assets such as mobile devices, cloud-connected access readers, visitor management tablets, and shared amenities by employees can lead to easy theft.

Employees and the security staff could be improperly trained or simply not aware of the existing security policy and procedures, leading to poor management of assets.

Your employees might forget or refuse to wear their ID badges at all times, leaving the cards open to theft and making it harder to authenticate the identities of the people in the office.

Higher management might simply have failed to implement proper procedures suggested by a previous audit, leaving holes in the system.

Visitor and contractor management #

Visitors, too, might prove to be an issue. Many third-party contractors and employees don't wear their assigned access badges all the time, causing the system to work improperly. Their photos might also be unrecognizable on their temporary badges. Poor control over the visitors that enter your space is another major problem often found in security audits. Many employees either escort their guests with them or they don't make the proper entries in the visitor registers.

Security screening of the employees of a third-party contractor is another critical issue for businesses, and this process is one that often requires maintenance by outside experts. Many employees working with contractors are not fully screened in normal situations.

To work around this issue, only hire contractors that you have personally screened or ones that you already trust. If this is not possible due to time constraints, make sure that you're reading reviews and checking that the service you have hired is legitimate and well-known.

While it's unlikely that anyone would pose as a contractor to gain access to your facility, an untrustworthy visitor might be tempted to take or look at sensitive information. Cut down on this kind of issue in your physical security risk assessment by doing the proper homework before any paperwork is signed.

Equipment and system failures #

Other problems stem from the equipment that you use in your security system. A lack of security when handling and movement of documents and files within the company, beyond its walls and through the internet is a problem that many facility owners encounter. Improper or faulty monitoring of your security system by untrained system administrators is another issue that can cause all sorts of problems.

The regular testing, maintenance, and monitoring of the security equipment at all points are often not conducted as defined in your policy. Inadequate lighting inside and outside the building, parking lot, and access points can lead to easier burglary and theft. Intrusion detection systems, fire alarm systems, and CCTV monitoring systems, among other equipment, are often not properly tested, meaning they might be inoperative without anyone noticing.

Prioritizing security risks: high, medium, and low #

Not all vulnerabilities carry equal risk. When conducting your assessment, prioritize findings based on their potential impact to operations and safety. This helps you allocate resources effectively and address the most critical issues first.

Use this framework to categorize your findings:

Critical: Issues that could lead to immediate safety threats or major security breaches, such as broken access controls at main entry points, non-functional fire suppression systems, or complete CCTV coverage failures in high-value areas.

High: Significant vulnerabilities affecting valuable assets or operations, including unmonitored blind spots in surveillance coverage, inadequate visitor screening procedures, or outdated access permissions that haven't been reviewed.

Medium: Process gaps that reduce security effectiveness but don't pose immediate threats, such as inconsistent badge-wearing policies, incomplete visitor logs, or irregular equipment maintenance schedules.

Low: Minor compliance or documentation issues that should be addressed but don't significantly impact security, like missing signage, outdated policy documents, or cosmetic equipment damage.

Document each finding with its assigned priority level, estimated remediation cost, and recommended timeline. This structured approach ensures your security budget and efforts focus on what matters most.

Scheduling physical security assessments #

The requirement of physical security assessment varies by the type of organization you run, the area you call home, local regulations, and rules, and even industry compliance measures.

Most organizations conduct comprehensive security assessments at least annually, with many high-security environments opting for quarterly or bi-annual reviews. Some businesses with greater security requirements or organizations that are very large tend to run a physical security assessment twice per year or even quarterly.

The scheduled security assessments should be done in accordance with the rules and regulations of your local authorities and leading industry best practices. Some assessments, too, are required by the Occupational Safety and Health Administration (OSHA), but those are regulated depending on the specific industry.

In order to err on the side of caution, perform a full audit at least once a year. On a monthly or even weekly basis, however, you can choose to do your own smaller inspections, which can help catch issues before they turn into security risks.

Taking all of the above into consideration, you need to do a bit of careful planning to make sure that you aren't accidentally leaving anything out, no matter how small. There are a few major categories that should be considered in your physical security audit checklist.

A step-by-step assessment process #

Follow these steps for a thorough assessment:

1. Define the scope. Determine which facilities, assets, and systems you'll assess. Identify critical areas and high-value assets.

2. Assemble your team. Include representatives from physical security, IT, facilities, and relevant departments. Cross-functional teams catch what siloed teams miss.

3. Review existing documentation. Gather security policies, previous audit reports, incident logs, and access control configurations to establish your baseline.

4. Conduct the physical inspection. Walk through all areas, paying attention to entry points, perimeter boundaries, and equipment locations. Test locks, verify camera angles, and check lighting.

5. Interview stakeholders. Talk to security staff, employees, and management. Ask about challenges and procedures that work differently in practice than on paper.

6. Test your controls. Verify that access controls, alarms, CCTV, and emergency systems function as intended. Simulate scenarios like after-hours access and alarm triggers.

7. Document what you find. Record vulnerabilities with photos, detailed notes, and location information. Use consistent methods so findings can be tracked.

8. Analyze and prioritize. Apply the risk framework to categorize issues. Consider both likelihood and consequence.

9. Create a remediation plan. Assign ownership, set timelines, estimate costs, and establish follow-up procedures for each finding.

Assessing cloud-based and connected access systems #

Modern access control systems are network-connected, which expands both capabilities and vulnerabilities. Your assessment should include these digital components.

Key areas to evaluate:

Credential management: How are credentials issued, modified, and revoked? Check that the process is timely and includes proper approval workflows. Verify that terminated employees lose access immediately.

Audit logs: Confirm that access logs are comprehensive and retained according to your requirements. Test that you can quickly retrieve and analyze logs when investigating incidents.

Remote access: Review who can access the platform remotely and what they can do. Ensure administrators use multi-factor authentication and sessions are logged.

Backups and recovery: Verify that configurations and data are backed up regularly and that you can restore operations if primary systems fail.

Mobile credentials: If using mobile access, assess how devices are enrolled, how credentials are stored, and what happens if a device is lost.

Cloud-based platforms often provide centralized visibility and real-time monitoring that enhance security management between formal assessments. Dashboard analytics, automated alerts, and reporting features help you maintain awareness of your security posture.

For each aspect of your physical security system, you need to list all of the corresponding elements or policies. Get started with a few simple steps, which will all help you gain a better understanding of your building. Assess the physical security risk level for each piece of technology or hardware that you have installed.

Draft a security management policy if you don't have one implemented already, then make sure your controls work with this new outline. Audit and assess the security level of each employee or access level, making sure that no one has more or less access than they actually need. And if you find major issues, correct them accordingly as soon as possible.
