JUEX-NM-000190 - The Juniper EX switch must be configured to protect audit information from unauthorized modification.

Information

Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit network device activity.

If audit data were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve.

To ensure the veracity of audit data, the network device must protect audit information from unauthorized modification.

This requirement can be achieved through multiple methods, which will depend upon system architecture and design. Some commonly employed methods include ensuring log files receive the proper file system permissions and limiting log data locations.

Network devices providing a user interface to audit data will leverage user permissions and roles identifying the user accessing the data and the corresponding rights that the user enjoys to make access decisions regarding the modification of audit data.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Configure the network device to protect audit information from unauthorized modification.

set system login class <name> permissions <permission sets or 'all'>
set system login class <name> deny-commands <appropriate commands to deny>
set system login class <name> deny-configuration-regexps <appropriate configuration hierarchy to deny>

set system login user <account name> class <name>
