Assessment Title

Rule Text

The Red Hat Enterprise Linux operating system must off-load audit records onto a different system or media from the system being audited.

Description

Discussion Text

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

Checks

DISA STIG (Manual Reference)

Verify the operating system off-loads audit records onto a different system or media from the system being audited.

To determine the remote server that the records are being sent to, use the following command:

# grep -i remote_server /etc/audisp/audisp-remote.conf
remote_server = 10.0.21.1

If a remote server is not configured, or the line is commented out, ask the System Administrator to indicate how the audit logs are off-loaded to a different system or media. 

If there is no evidence that the audit logs are being off-loaded to another system or media, this is a finding.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# oval:mil.disa.stig.rhel7:def:86707
if [ -f /etc/audisp/audisp-remote.conf ]; then \
    grep -q '^remote_server[ ]*=[ ]+.*$' /etc/audisp/audisp-remote.conf && echo "PASS" && exit 0 || echo "FAIL" && exit 1; else \
    echo "FAIL" && exit 1; fi

Remediation

Configure the operating system to off-load audit records onto a different system or media from the system being audited.

Set the remote server option in "/etc/audisp/audisp-remote.conf" with the IP address of the log aggregation server.
