Assessment Procedure

Check Text

From an SSH session connected to the ESXi host, or from the ESXi shell, run the following command:

# grep -i "^MACs" /etc/ssh/sshd_config

If there is no output or the output is not exactly "MACs hmac-sha1,hmac-sha2-256,hmac-sha2-512", this is a finding.

Implementation Procedure

Fix Text

From an SSH session connected to the ESXi host, or from the ESXi shell, add or correct the following line in "/etc/ssh/sshd_config":

MACs hmac-sha1,hmac-sha2-256,hmac-sha2-512
