CASA-VN-000520 - The Cisco ASA remote access VPN server must be configured to generate log records containing information to establish the source of the events.

Information

Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis, security personnel need to know the source of the event.

In addition to logging where events occur within the network, the log records must also identify sources of events such as IP addresses, processes, and node or device names.

Solution

Configure the ASA to generate log records containing information to establish the source of the events 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
