Limit Consecutive Login Attempts for SSH

SedangLevel 1Otomatissolaris

Deskripsi

The 'MaxAuthTries' parameter in the /etc/ssh/sshd_config file specifies the maximum number of authentication attempts permitted per connection. By restricting the number of failed authentication attempts before the server terminates the connection, malicious users are blocked from gaining access to the host by using repetitive brute-force login exploits. Audit: MaxAuthTries must be 6 or less, or commented out (default 6).
