The ICS must be configured to generate log records containing sufficient information about where, when, identity, source, or outcome of the events.

An XCCDF Rule

Description

Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. VPN gateways often have a separate audit log for capturing VPN status and other information about the traffic (as opposed to the log capturing administrative and configuration actions). Associating event types with detected events in the network audit logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured VPN gateway. Satisfies: SRG-NET-000078-VPN-000290, SRG-NET-000079-VPN-000300, SRG-NET-000088-VPN-000310, SRG-NET-000089-VPN-000330, SRG-NET-000091-VPN-000350, SRG-NET-000077-VPN-000280, SRG-NET-000313-VPN-001050, SRG-NET-000492-VPN-001980

A Manual Procedure

In the ICS Web UI, navigate to System >> Log/Monitoring >> User Access >> Settings.

Note: If the site uses SNMP, the configuration can be used in conjunction with this requirement which is recommended. By default, SNMP is disabled. The device only supports Simple Network Management Protocol version 3 (SNMPv3) in a DOD configuration. The device supports queries only, traps only, or both when enabling SNMP. Refer to SRG-NET-000335-VPN-001270 for configuration.
