Title

The network devices must only allow management connections for administrative access from hosts residing in the management network. (Cat II impact)

Discussion

Remote administration is inherently dangerous because anyone with a sniffer and access to the right LAN segment could acquire the device account and password information. With this intercepted information they could gain access to the infrastructure and cause denial of service attacks, intercept sensitive information, or perform other destructive actions.

Check Content

Review the configuration and verify management access to the device is allowed only from hosts within the management network. If management access can be gained from outside of the authorized management network, this is a finding.

Fix Text

Configure an ACL or filter to restrict management access to the device from only the management network.
