What is the main purpose of an EPC zone?

The main purpose of an EPC (Endpoint Compliance) zone is to define the trust level required for resource access. This is a crucial aspect of network security, where the EPC zone assesses and establishes a user's device compliance status prior to granting access to corporate resources. By categorizing devices based on their compliance with organizational security policies (such as whether they have up-to-date antivirus software or the latest security patches), an EPC zone ensures that only trusted devices are allowed access to sensitive information and resources. This level of control is essential for safeguarding against potential threats that non-compliant or less secure devices might pose to the overall network.

Other options like categorizing users by location, determining password strength, or limiting devices per user are not primary functions of an EPC zone. While these aspects may contribute to overall security and management strategies, they do not pertain directly to the core functionality of trust assessment in the context of endpoint compliance specifically.
