Check: SRG-NET-000334-IDPS-00191

Intrusion Detection and Prevention Systems SRG: SRG-NET-000334-IDPS-00191 (in versions v3 r2 through v2 r2)

Title

The IDPS must off-load log records to a centralized log server. (Cat II impact)

Discussion

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading ensures audit information does not get overwritten if the limited audit storage capacity is reached and also protects the audit record in case the system/component being audited is compromised. This also prevents the log records from being lost if the logs stored locally are accidentally or intentionally deleted, altered, or corrupted.

Check Content

Verify the IDPS off-loads log records to a centralized log server. If the IDPS does not off-load log records to a centralized log server, this is a finding.

Fix Text

Configure the IDPS to off-load log records to a centralized log server.
