Assessment Title

Rule Text

The Cisco device must be configured to audit all administrator activity.

Description

Discussion Text

This requirement supports non-repudiation of actions taken by an administrator and is required in order to maintain the integrity of the configuration management process. All configuration changes to the network device are logged, and administrators authenticate with two-factor authentication before gaining administrative access. Together, these processes will ensure the administrators can be held accountable for the configuration changes they implement. To meet this requirement, the network device must log administrator access and activity.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Review the Cisco router configuration to verify that it is compliant with this requirement as shown in the example below.

hostname R1
!
logging userinfo
!
…
…
…
archive
 log config
 logging enable
!

Note: The logging userinfo global configuration command will generate a log when a user increases his or her privilege level.

If logging of administrator activity is not configured, this is a finding.

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

echo "FAIL"
exit 1

Remediation

Configure the router to log administrator activity as shown in the example below.

R1(config)#logging userinfo
R1(config)#archive
R1(config-archive)#log config
R1(config-archive-log-cfg)#logging enable
R1(config-archive-log-cfg)#logging size 1000
R1(config-archive-log-cfg)#notify syslog contenttype plaintext
R1(config-archive-log-cfg)#hidekeys
R1(config-archive-log-cfg)#end
