What does Perimeter Security primarily focus on?

Perimeter Security primarily focuses on enforcing access control policies and monitoring traffic because it is designed to protect the boundaries of a network from unauthorized access and malicious activities. This includes establishing rules that dictate what type of traffic can enter or leave the network, as well as actively monitoring this traffic to detect any suspicious behavior.

By enforcing access controls, organizations can ensure that only authorized users and systems can interact with sensitive information or resources, thereby creating a first line of defense against external threats. Monitoring traffic allows for real-time detection of potential breaches, enabling quick responses to security incidents before they can escalate.

While encrypting communications is vital for protecting data in transit, it does not directly relate to perimeter security, which encompasses broader network defenses. Monitoring internal traffic is also important, but it falls more under internal security measures, focusing on traffic already within the trusted network perimeter. Scanning for intrusions is related to security as well, but it specifically refers to identifying threats rather than the broader scope of access control and traffic management that perimeter security entails.
