We are back with another CentOS 7 Linux article. Today you are going to learn how to install OpenVAS on CentOS 7 Linux. It is free software that basically uses the Nessus software engine to check and test security holes.
Since 2005, when Nessus software switched from open source mode to closed source version (with activation license), GreenBone has continued its open-source project and initially developed a vulnerable scanner software called GNessUs, which was later renamed OpenVAS. OpenVAS stands for Open Vulnerability Assessment System, which is now available for free to scan your entire network and identify the security holes. The steps for installing OpenVAS are very simple and all you have to do is run a number of Linux commands.
