Scanners could either be friendly or malicious depending on the intentions of a developer. Naturally, different scanners can accomplish this objective through varying methods.Īlso, some scanners work better than others depending on the type of system or problem you have. The purpose of executing a vulnerability scan is to find known or undiscovered vulnerabilities in the devices in your network or programs in your system. This is the part where the scanner can take advantage of a discovered vulnerability that can crash a program or OS for the sake of giving the user a clearer idea of how serious or benign a given security hole is. The first step in doing a proper vulnerability scan involves the examination of running applications, operating systems (OS), open ports, and active IP addresses.įrom there, the scanner may either create a report or move to the next step depending on its findings.Īfterwards, the user must discern the patch level of the applications or OS. A vulnerability scanner is a software application that's specifically developed to map systems and search for vulnerabilities in a network, computer, or program.
