For starters, I'd advise everyone to avoid using passwords. Passwords are less secure than secure socket shell (SSH) or virtual private network (VPN) keys, so instead consider utilizing these or similar technologies. Use smart cards and other advanced ways whenever possible; this eliminates the need to memorize passwords or store them on the system for a hacker to figure out. Second, ensure sure there are user-awareness programs in place. All available steps must be taken to ensure that all network users are aware of the security risks and the essential security procedures to mitigate these risks. To evaluate user awareness, you can run social-engineering tests. Protection cannot be carried out in the proper sense of the term until all users are aware of specific network elements. Biometrics is the third sort of control. Biometrics is a term that refers to the technology that measures and analyzes human bodily characteristics for authentication purposes, such as DNA, fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements. Everyone's fingerprints, eye retinas/irises, and voice are unique. These, on the other hand, can be replicated by determined and aggressive hackers. As a result, this isn't a 100 percent preventative measure
