ClearPass Policy Manager (CPPM) can receive detailed information about client device type, OS, and status from ClearPass OnGuard. ClearPass OnGuard is part of the ClearPass suite and provides posture assessment and endpoint health checks. It gathers detailed information on the status and security posture of devices trying to connect to the network, such as whether antivirus software is up to date, which operating system is running, and other details that characterize the device's compliance with the network's security policies.

• Aruba ClearPass product documentation that details the capabilities of ClearPass OnGuard.
• Network security resources that describe endpoint health checks and the importance of device posture assessment for access control.

To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.

• Digital forensics and network security protocols that underscore the importance of accurate timekeeping for maintaining a digital chain of custody.
• NTP configuration guidelines for network devices, emphasizing the use of authentication to prevent tampering with clock settings.

Public Key Infrastructure (PKI) relies on a trusted root Certification Authority (CA) to issue certificates. Devices and users must trust the root CA for the PKI to be effective. If a root CA certificate is not pre-installed or manually chosen to be trusted on a device, any certificates issued by that CA will not be inherently trusted by the device.

The primary reason for adding a "Log Settings" definition in the ArubaOS Diagnostics > System > Log Settings page is to configure the Syslog server settings for the server to which the Mobility Controller (MC) forwards logs for a particular category and level. This setting enables the MC to send detailed logs to a Syslog server for centralized logging and monitoring, which is essential for troubleshooting, security analysis, and compliance with various policies.References:
