SSH is an indispensable part of Linux administration, enabling access to remote servers and desktops for admin tasks. Although SSH offers more secure credentials than what it replaced (Telnet), its security alone cannot guarantee safe operations. For instance, an attacker could launch a brute-force attack on your machine by constantly attempting to login until he or she gets the correct credentials.
Penetration testing (or pentesting) plays an integral part in cybersecurity. Ethical hackers employ this practice to simulate cyberattacks against systems, networks, or applications to locate vulnerabilities before malicious hackers do. The goal of pentesting is identifying and repairing security weaknesses.
Imagine you run a small business with several web services, such as a corporate website, an employee intranet, and a remote access server for staff working from home. Each service typically requires its port: 80 for the website, 443 for secure access, and 22 for SSH. Managing multiple ports complicates configuration and increases your exposure to security risks.
Network admins must scan for security vulnerabilities and patch them promptly to prevent attacks and security breaches. Metasploit is an open-source framework for detecting threats and vulnerabilities.
