Series: New Controls in ISO/IEC 27001:2022 Annex A

Physical Security Monitoring

In this article series, we are analyzing the implementation aspects of the 11 new controls of ISO/IEC 27001:2022 Annex A. The fourth article explores Control 7.4 (Physical security monitoring).

Control

Control 7.4 (Physical security monitoring) defines the best practices for detecting and preventing unauthorized physical access by continuously monitoring the premises of an organization.

Attributes

Implementation of this control would help an organization prevent intrusions by detecting attempts to enter the premises in an unauthorized manner. This would help in protecting the physical security of the organization and defending it against attempted breaches of confidentiality, integrity and availability of sensitive assets.

Implementation

The organization should make arrangements for monitoring its premises by implementing appropriate surveillance mechanisms, like human guards, intruder alarms, closed-circuit television etc. The buildings that house critical systems should be continuously monitored to detect / prevent any unauthorized access. Alarms should be installed in all unoccupied areas and they should cover all external doors and accessible windows.

It must be ensured that the monitoring systems are protected from unauthorized access to prevent tampering / de-activation of the systems and theft of video feeds. The systems should be tested at regular intervals to ensure that they are functioning properly. The organization must consider relevant laws and regulations pertaining to personally identifiable information (PII), surveillance and data protection, while implementing monitoring systems.

Artefacts

The contents and implementation of the following security policies and procedures may be impacted by the above control:

• Physical Security Policy – This policy establishes the rules for granting, controlling, monitoring, and removal of physical access to the organization’s premises. It identifies the sensitive areas within the organization and defines and restricts access to the same.

• Incident Response Procedure – Procedures for the detection and containment of, and recovery from, physical security incidents should be established.

• Physical Security Logs – The logs and records that are generated by surveillance and monitoring systems should be protected and retained for defined time-periods.
