Title

The Juniper router must be configured to send log data to at least two syslog servers for the purpose of forwarding alerts to the administrators and the Information System Security Officers (ISSO). (Cat I impact)

Discussion

Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply create a new account. Notification of account creation is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the creation of accounts and notifies administrators and ISSOs. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

Check Content

Verify that the router is configured to send logs to at least two syslog servers. The configuration should look similar to the example below: system { syslog { host x.x.x.x { any info; } host x.x.x.x { any info; } } If the router is not configured to send log data to the syslog servers, this is a finding.

Fix Text

Configure the router to send log data to the syslog servers as shown in the example below. set syslog host x.x.x.x any info set syslog host x.x.x.x any info
