What methods does EPC use to enhance security for untrusted environments?

The correct answer highlights the importance of verifying the security posture of devices in untrusted environments. EPC, or Endpoint Control, enhances security by checking for the presence and activation of required security software on devices attempting to connect to the network. This is critical in untrusted environments, as it ensures that only devices that meet specific security standards, such as having up-to-date antivirus software or active firewalls, can access sensitive resources.

By enforcing these checks, EPC helps prevent compromised devices from connecting to the network, thereby reducing the risk of malware, data breaches, and other security threats. This proactive approach to security management is essential for maintaining the integrity and confidentiality of the network, especially when users may be accessing it from potentially insecure locations or devices.
