The ICS must be configured to forward all log failure events where the detection and/or prevention function is unable to write events to local log record or send an SNMP trap that can be forwarded to the SCA and ISSO.
An XCCDF Rule
Description
<VulnDiscussion>It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Automated alerts can be conveyed in a variety of ways, including, for example, telephonically, via electronic mail, via text message, or via websites. Log processing failures include software/hardware errors, failures in the log capturing mechanisms, and log storage capacity being reached or exceeded. The VPN daemon facility and log facility are messages in the log, which capture actions performed or errors encountered by system processes.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Event logs are also updated to local logs by default in addition to the central syslog server. However, if the site uses SNMP, the following must be configured since SNMP is disabled by default.
In the ICS Web UI, navigate to System >> Log/Monitoring >> SNMP.
1. Under "SNMP Version data", select "v3".
2. Under "Agent Properties", check "SNMP Traps".
3. Under "Agent Properties", configure a System Name, Location, and Contact.
