Assessment Title

Rule Text

The Photon operating system must configure sshd with a specific ListenAddress.

Description

Discussion Text

Without specifying a ListenAddress, sshd will listen on all interfaces. In situations with multiple interfaces, this may not be intended behavior and could lead to offering remote access on an unapproved network.

Assessment Procedure

Check Text

At the command line, execute the following command:

# sshd -T|&grep -i ListenAddress

If the ListenAddress is not configured to the VCSA management IP, this is a finding.

Implementation Procedure

Fix Text

Open /etc/ssh/sshd_config with a text editor.

Ensure that the "ListenAddress" line is uncommented and set to a valid local IP:

Example:

ListenAddress 169.254.1.2

Replace "169.254.1.2" with the management address of the VCSA.

At the command line, execute the following command:

# service sshd reload
