Recommended Ciphers, MACs, and Algorithms

MediumLevel 1Manual reviewaruba-cx

Description

This sequence describes configuring SSH server ciphers, MACs, and algorithms

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Run 'show ssh server' and review the Ciphers, Host Key Algorithms, Key Exchange Algorithms, MACs and Public Key Algorithms lists. Only organisation-approved strong algorithms should be enabled (set with 'ssh ciphers', 'ssh macs', 'ssh key-exchange-algorithms', 'ssh host-key-algorithms', 'ssh public-key-algorithms').

How it is fixed

Fix method: Guidance or infrastructure patch
