How does physical access control prevent insider threats?

Physical access control is vital in preventing insider threats as it specifically restricts who can enter secure areas where sensitive information and critical systems are housed. By controlling access to these locations, organizations can effectively minimize the risk of unauthorized personnel gaining entry, which could lead to theft, tampering, or unauthorized disclosure of sensitive data.

Limited access ensures that only individuals who have been properly vetted and have a legitimate need to be in those areas can do so. This creates a physical barrier that can significantly reduce opportunities for potential insider threats, such as employees or contractors who may misuse their access to the organization’s resources.

While monitoring emails, encrypting data, and conducting employee background checks are all important security measures, they address different aspects of security and may not directly prevent unauthorized physical access to sensitive environments.
