View rawSecure SSH access to VPS servers by implementing industry-standard hardening practices.
This skill helps AI agents harden SSH configuration on VPS servers. SSH is the primary entry point for server management, making it a critical attack vector. Proper SSH hardening prevents unauthorized access, brute-force attacks, and credential theft.
Critical understanding: Root can do anything. One typo, one compromised session, and your entire system is gone. Passwords can be guessed. SSH keys can't be brute-forced in any practical timeframe.
