I need some help with configuration on my server. I ran a test for the firewall security and I have a red warning on my CSF firewall security.
Here is what it said:
SSH/Telnet Check
Check SSH PasswordAuthentication For ultimate SSH security, you should consider disabling PasswordAuthentication and only allow access using PubkeyAuthentication
Can you please advise me with what change I would need to make on the server to get rid of the warning?
