Description
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Proper configuration of rsyslog ensures that information critical to forensic analysis of security events is available for future action without any manual offloading or cron jobs. Satisfies: SRG-OS-000205-GPOS-00083, SRG-OS-000274-GPOS-00104, SRG-OS-000275-GPOS-00105, SRG-OS-000276-GPOS-00106, SRG-OS-000277-GPOS-00107, SRG-OS-000479-GPOS-00224
