Secure Shell (SSH).
Purpose: Provides secure encrypted communication and remote shell access over an insecure network.
Vulnerabilities: Weak passwords, SSH protocol weaknesses (e.g., vulnerabilities in SSHv1, insecure cryptographic algorithms), Misconfigurations (e.g., allowing root login, improper file permissions), Outdated software (e.g., unpatched SSH servers), Brute force attacks.
Tools: Nmap, Hydra, Metasploit, John the Ripper, SSH-BadKeys, SSH-Audit.
