The Cisco ASA remote access VPN server must be configured to generate log records containing information that establishes the identity of any individual or process associated with the event.

Description
Without information that establishes the identity of the subjects (i.e., users or processes acting on behalf of users) associated with the events, security personnel cannot determine responsibility for the potentially harmful event.

Who does this work

6 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-239971r666319_chk)

Review the ASA configuration to determine if VPN events are logged as shown in the example below. logging class vpn trap notifications logging class vpnc trap notifications logging class vpnfo trap notifications logging class webfo trap notifications logging class webvpn trap notifications logging class svc trap notifications Note: A logging list can be used as an alternative to using class. If the ASA is not configured to log entries containing information to establish the identity of any individual or process associated with the event, this is a finding.

Fix Text (F-43163r666318_fix)

Configure the ASA to generate logs containing information to establish the identity of any individual or process associated with the event as shown in the example below. ciscoasa(config)# logging class vpn trap notifications ciscoasa(config)# logging class vpnc trap notifications ciscoasa(config)# logging class vpnfo trap notifications ciscoasa(config)# logging class webvpn trap notifications ciscoasa(config)# logging class webfo trap notifications ciscoasa(config)# logging class svc trap notifications ciscoasa(config)# end
