Which of the following is considered a technical control in cybersecurity?

Technical controls in cybersecurity refer to the mechanisms that are implemented through technology to mitigate risks and enhance security. These controls are often automated and can include hardware and software solutions that protect systems and data from threats.

In this case, identifiers, such as IDs, fall under the category of technical controls. They are used to authenticate users, grant access to resources, and track user activity within a system. The implementation of identification mechanisms is crucial to enforce security policies and ensure that only authorized users have access to sensitive information or systems.

On the other hand, the training manual, policy review, and awareness programs are classified as administrative or physical controls rather than technical ones. While they are important for establishing a secure environment and ensuring that staff understand procedures and policies, they do not involve the technological measures necessary to block or mitigate threats directly. Thus, the emphasis on IDs highlights their role as a direct technological measure to strengthen cybersecurity defenses.
