Assumptions in Physical Security and What Security Managers Should Rethink

Security managers carry a heavy responsibility: safeguarding people, property, and critical assets. To manage the complexity of this task, they often rely on assumptions about their security systems, protocols, and organizational security culture. While some assumptions may hold, others create dangerous blind spots. Let’s explore common assumptions security managers may make, the risks they carry, and practical solutions that will lead to a stronger security posture for your facility.

Assumption 1: All Access Points Are Adequately Secured

Many security managers assume that all access points fortified with locks, keycards, or biometric scanners are automatically inaccessible to third parties or intruders. This leads to the assumption that only authorized personnel may enter the access point, but this is not the case.

Reality Check: Not all access points are created equal, and secondary doors, maintenance entries, and emergency exits often lack the same level of security as primary entrances, leaving exploitable gaps. Even when robust access controls like keycards or biometric scanners are in place, tailgating, where unauthorized individuals follow authorized personnel, remains a common practice. Surveillance systems, while also valuable, are not foolproof. Cameras may miss blind spots and require active monitoring to be truly effective. These overlooked vulnerabilities can compromise overall security if not addressed.

Our Security Solutions

  1. Conduct regular Security Vulnerability Assessments (SVAs) to identify and address weak points.
  2. Implement anti-tailgating solutions like turnstiles or mantraps.
  3. Regularly test surveillance systems and have trained personnel monitor them in real time.

Assumption 2: Employees Are Aware of Security Protocols and Will Follow Them

Employee compliance is another element of business sometimes taken for granted. Security managers may believe that staff are well-trained and will consistently follow protocols, such as wearing badges, reporting suspicious behavior, and securing sensitive areas.

Reality Check: It can be easy to assume that employees are well-versed in security procedures, but gaps in training can lead to misunderstandings, especially if training is infrequent or lacks hands-on components. Even well-meaning staff can make errors, such as propping open doors for convenience or forgetting to lock doors, inadvertently creating vulnerabilities. 

Additionally, the threats posed by malicious insiders are a serious concern and require proactive measures to address them. Learn more about the impact of internal breaches and Protecting Your Business From Insider Threats here.

Our Security Solutions

  1. Establish a culture of security awareness through regular training and simulated drills.
  2. Create actionable protocols to minimize confusion and noncompliance.
  3. Conduct enhanced due diligence on employees and implement thorough background checks, plus insider threat detection programs.

Assumption 3: Perimeter Barriers Are Sufficient to Deter Intrusion

Physical barriers like fences, gates, and walls are sometimes assumed to be impenetrable deterrents. Security managers may believe these structures are enough to prevent unauthorized entry.

Reality Check: While perimeter barriers can deter casual intruders, highly motivated or well-equipped adversaries may still find ways to bypass them. The effectiveness of these barriers also depends on consistent maintenance. Damaged or poorly maintained fences and gates can provide easy access points for intruders. Additionally, overreliance on technology poses its own risks, as automated gates and fences can be vulnerable to hacking or mechanical failures, undermining their reliability as a first line of defense.

Our Security Solutions

  1. Conduct regular inspections and maintenance of all barriers.
  2. Enhance perimeter security with layered defenses, such as motion detectors and infrared sensors.
  3. Integrate security personnel into perimeter monitoring to address dynamic threats.

Assumption 4: Critical Assets Are Located in Highly Monitored Areas

It may be assumed that the most critical of assets, whether physical or digital, are stored in well-secured and monitored locations. This may lead to complacency in auditing these areas.

Reality Check: Critical assets are often assumed to be well-protected, but monitoring gaps can undermine this security. Cameras and alarms in these areas may not be actively watched, leading to delayed responses during emergencies. Additionally, even the most secure areas can be compromised if access control policies are outdated or not strictly enforced. Beyond human threats, environmental risks such as flooding, fires, or power outages can also jeopardize critical assets if proper precautions aren’t in place.

Our Security Solutions

  1. Perform a comprehensive SVA to identify vulnerabilities.
  2. Employ redundant monitoring systems to ensure continuous oversight.
  3. Secure critical assets against environmental threats with disaster-resistant storage solutions.

5 Broader Assumptions Security Managers May Make

Beyond these core assumptions, there are broader beliefs that can further expose vulnerabilities within your facility, including but not limited to:

  1. Alarm System Reliability: Security managers may assume that alarm systems will always function flawlessly. In reality, power outages, calibration issues, or software glitches can render these systems ineffective.

Solution: Implement backup power supplies and regularly test alarm systems.

  1. Lighting Effectiveness: Adequate lighting is assumed to deter intrusions. However, poor placement or malfunctioning lights can create dark spots.

Solution: Use motion-activated lighting and conduct nighttime security audits.

  1. Technological Failures: The assumption that all technology will function as intended can lead to significant gaps in security, especially during cyberattacks or natural disasters.

Solution: Incorporate manual procedures as a contingency for technology failures.

  1. Environmental Preparedness: Many strategies fail to account for natural disasters, such as hurricanes or earthquakes, which can disable security measures.

Solution: Develop an Emergency Action Plan that integrates physical security protocols.

  1. Social Engineering Blind Spots: Human susceptibility to social engineering is highly underestimated. Tactics like phishing or pretexting can also bypass even the most advanced security systems.

Solution: Provide regular training on recognizing and responding to social engineering attempts.

The Cost of Complacency

Assumptions are natural, but they should never go unexamined. Relying solely on them can have serious consequences.

Security managers can strengthen their organizations’ resilience by recognizing the limitations of these assumptions and implementing strategies to address them. Addressing these risks also requires a proactive approach, including investing into a Security Vulnerability Assessment (SVA) to uncover and mitigate your security gaps. Equally important is the need to conduct Security Testing. Having protocols, policies, and security technology in place is a great start, but if those systems are not interrogated, the security efforts could be fruitless.
