Best Vulnerability Scanners for 2020
The responsibilities of IT security teams cover not only the setup of prevention systems to protect their network and assets connected to it, but also to make sure that these systems remain effective over time. After establishing a virtual perimeter fence, it is important to make sure that there are no cracks, holes, or any type of vulnerability. For this checking process, a vulnerability scanner is an effective tool because of several advantages it provides. Most vulnerability scanning tools are easy to use and generate quick results through reports. They can be used to monitor continuously or be performed repeatedly within a time period.
A vulnerability scanner is a helpful tool but should exist with other security tools. To get the most benefit, IT security teams should use it to scan all devices and access points in the network. Scan frequently and document all results. There should also be assigned persons for every network asset who takes accountability of device security, such as regularly patching all discovered vulnerabilities with software updates.
What are vulnerability scanners and their features?
A vulnerability scanner is a software application that searches, identifies, and assess computer hardware, firmware, operating systems, and applications for known weaknesses. Vulnerability scanning software today comes as cloud-based software offered as-a-service that checks vulnerabilities against one or more databases of reported vulnerabilities. Scanners search for network access points and devices and creates an inventory. Next, it identifies each device, retrieving information about its systems and applications. If authenticated scanning is performed, it will use valid credentials to log in and scan more thoroughly. Unauthenticated scanning is usually performed to check externally accessible assets.
After a complete inventory, the vulnerability scanner will check each inventory item against a database of known vulnerabilities and then create a report on its findings. For example, it may discover a laptop running an operating system no longer supported by its developer and would be vulnerable to the latest malware.
