Discussion

Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. ESXi must implement cryptographic modules adhering to the higher standards approved by the federal government because this provides assurance they have been tested and validated.

Check Content

From an ESXi shell, run the following command:

# /usr/lib/vmware/openssh/bin/sshd -T|grep ciphers

Expected result:

ciphers aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,aes128-ctr

If the output does not match the expected result, this is a finding.
