While businesses are increasingly focused on cybersecurity, physical security often gets overlooked, despite remaining an obvious and significant threat. If physical access is not tightly controlled, it undermines your entire security posture, regardless of how robust your digital defences are. Unlocked doors, weak windows, or unmonitored delivery entrances can become easy points of entry, exposing your business to serious risks.
An unlocked door, a loose window, or even a delivery entrance that’s not properly secured can all be easy ways for someone to slip in. These are common mistakes people make with their physical security that leave your business vulnerable.
In this article, we explore three common physical security mistakes and provide actionable steps to mitigate them, ensuring your business remains secure.
Ignoring physical barriers
One of the biggest mistakes companies make is underestimating the importance of physical barriers. While cameras and alarms are essential, they do not replace strong doors, secure windows, and robust locking mechanisms.
If you’re using flimsy locks, thin doors, or windows that can be easily broken into, you’re leaving your business at risk. Without strong barriers, even the best security system won’t help if someone is determined to get inside.
A well-designed physical security strategy should adhere to standards like ISO 27001, which highlights the importance of securing sensitive areas with proper controls. For example, roller shutter doors can add an extra layer of protection beyond conventional locks, ensuring entry points are properly fortified.
NIST SP 800-53 recommends using security perimeters, access control, and monitoring to defend against unauthorised access​. Simply locking doors and windows is not enough. Businesses must consider reinforced materials and technologies such as biometric scanners and RFID cards to prevent breaches​.
Poor surveillance
Another common mistake is relying on outdated or poorly positioned surveillance systems. ISO 27001 outlines the need for comprehensive surveillance as part of a broader Information Security Management System (ISMS). However, even with cameras in place, they are ineffective if they miss key areas or produce low-quality footage.
Regular monitoring and maintenance are essential. Companies often neglect surveillance system updates, leaving them vulnerable. Predictive analytics and AI-powered systems can enhance surveillance by analysing large amounts of data in real time, quickly distinguishing between genuine threats and false alarms.
Moreover, modern systems integrated with cloud-based technologies allow remote access to surveillance data, providing businesses with greater control and ensuring their systems remain functional and secure.
Inadequate employee training
Even the most advanced security systems are only as effective as the people operating them. A widespread issue is insufficient employee training in physical security protocols. Employees should be well-versed in locking up, reporting suspicious activity, and managing visitors.
Frameworks like ISO 27001 and SOC 2 Type II emphasise the need for robust access controls and regular staff training to mitigate human error. Ensuring that employees are trained to understand and use physical security measures, such as biometric access or handling physical breaches, can dramatically reduce risks.
Furthermore, convergence between physical and cybersecurity requires staff to understand that threats can manifest in both realms, highlighting the importance of holistic training
By addressing these common mistakes, businesses can significantly reduce their vulnerability to physical security threats. Incorporating internationally recognised standards like ISO 27001 and NIST SP 800-53, along with regular staff training and modern surveillance technology, ensures that both physical and digital assets are properly secured.
Remember, a strong physical security strategy not only protects your business but also builds trust with clients and stakeholders, ensuring your operations are resilient to modern threats.
