CASA-VN-000510 - The Cisco ASA remote access VPN server must be configured to generate log records containing information to establish where the events occurred - vpnfo

Information

Without establishing where events occurred, 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, it is essential for security personnel to know where events occurred, such as VPN gateway components, modules, device identifiers, node names, and functionality.

Associating information about where the event occurred within the network provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured VPN gateway.

Solution

Configure the ASA to generate log records containing information to establish where the events occurred 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
