SSH Hardening and Automation User Setup with Ansible #

Here’s a little post about how I do SSH hardening for my RHEL9 homelab and how I ensure that the Ansible automation user is properly set. The playbook stems from an incident I had in Red Hat Insights where it was reported that I had an SSH configuration that allowed legacy ciphers. It was also adviced to create a crypto policy that disables weak algorithms.
