Description
Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state. Additionally, sensitive account information must not be revealed through error messages to unauthorized personnel or their designated representatives. Although, based on policy, administrator accounts must be created on the AAA server, thus this requirement addresses the creation of unauthorized accounts on the Juniper SRX itself. This does not negate the need to address this requirement on the AAA server and the event monitoring server (e.g., Syslog, Security Information and Event Management [SIEM], or SNMP servers).

Obtain a list of authorized user names that are authorized to view the audit log and console notification messages. Verify classes are created that separate administrator roles based on authorization. View user classes and class members by typing the following commands. [edit] show system login View class assignment for all users and template users configured on the Juniper SRX. Users with login classes audit-admin, security-admin, and system-admin have permission to view error message in logs and/or notifications. If classes or users that are not authorized to have access to the logs (e.g., crypto-admin) have permissions to view or access error message in logs and/or notifications, this is a finding.
