The Cisco NAC (Network Admission Control) Agent is a software agent that runs on endpoint devices (such as laptops, desktops, and mobile devices) to assess the security posture of the device before allowing it to access the network. The posture assessment checks for certain security configurations and policies that must be met before the device is granted network access.
The Cisco NAC Agent posture assessment can check for a variety of security-related items on the endpoint device. The four items that may be checked via the Cisco NAC Agent posture assessment are as follows:
A. Microsoft Windows registry keys: The Cisco NAC Agent may check for the presence or absence of specific registry keys on a Microsoft Windows device. These registry keys may be related to security policies or configurations that must be met before network access is granted.
B. The existence of specific processes in memory: The Cisco NAC Agent may check for the presence or absence of specific processes in memory on an endpoint device. These processes may be related to security policies or configurations that must be met before network access is granted.
D. If a service is started on a Windows host: The Cisco NAC Agent may check whether a specific service is running or not on a Windows device. This service may be related to security policies or configurations that must be met before network access is granted.
F. If an Apple iPad or iPhone has been "jail-broken": The Cisco NAC Agent may check whether an Apple iPad or iPhone has been "jail-broken" or has had its security settings modified to allow for unauthorized access or installation of applications. This is an important security check because jail-broken devices may pose a greater risk to the network.
The other items listed in the answer options are not typically checked via the Cisco NAC Agent posture assessment. For example:
C. The UUID of an Apple iPad or iPhone: The UUID (Universally Unique Identifier) of an Apple device is a unique identifier that is assigned to the device when it is manufactured. While this information may be useful in some contexts, it is not typically used as part of a posture assessment.
E. The HTTP User-Agent string of a device: The User-Agent string is a text string that is sent by a web browser or other client application to identify the client to the server. While this information may be useful for web-based authentication or access control, it is not typically used as part of a posture assessment.
G. If an antivirus application is installed on an Apple MacBook: While the presence of an antivirus application may be an important security check, this is not typically performed via the Cisco NAC Agent posture assessment. Instead, antivirus status may be checked via other mechanisms, such as an endpoint security solution or a network access control system.
