What to Look For
Brute Force Attacks on SSH servers that are open to the Internet are quite commonplace, as many attackers scan the Internet for these endpoints. Ensure that strong passwords and/or multi-factor authentication are in use to prevent successful attacks. Check network logs for additional information and review endpoint security to ensure that sensitive information is secure.
