Vulnerability assessment tools automate the process of vulnerability scanning. In this video, learn about the use of scanning tools, including port scanners and vulnerability scanners, along with banner grabbing as a scanning technique.
- [Instructor] Testing systems for security issues…is one of the most important tasks performed…by security professionals, but it can be a little tedious.…Security analysts must test for vulnerabilities…because if they don't, hackers will.…You're much better off if you discover an issue…and correct it than if an attacker discovers it…and exploits it.…Fortunately, vulnerability assessment tools…automate the process of vulnerability scanning.…There are three major categories of these tools.…Port scanners which simply probe a system…for open network ports, vulnerability scanners which check…those ports for known vulnerabilities,…and application scanners that probe deep…into web applications to detect flaws.…
Port scanners are the equivalent of rattling…all the door knobs on a server, looking for unlocked doors.…They check all of the possible 65,535 network ports…on a server to see which ones might be open.…The most popular port scanning tool…is a program called Nmap.…Let's give it a try.…I'm going to go ahead and run Nmap from the Linux…
