A Port Scanner is an application specifically designed to scan and probe a host and servers (virtual or physical) for ports that opened and exposed. This tool is useful for malicious intent. Hackers can use this tool to identify services running on a host and client allowing the exploitation of various vulnerabilities. The first port scanning tool I have used is the Nessus Network Scanning Utility, detecting malware and scans the web applications. Another scanner I used was NMap, which examines raw IP packets, host availability and services, provides running OS details and is available for most operating systems. For this forum, I will discuss Nessus Network Scanning Utility.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
