OpenVAS (GVM) has a large number of moving parts, services, and configuration items. To enable the feature, AD DS must be prepared. Accessing OpenVAS from the command line is a powerful feature that gives you full control over scan tasks, reports and other management tasks. The other options on the task have been left as default, as an exercise to see the outcome of the scan. Much time can be spent figuring out that a ‘gsad’, ‘gvmd’ and ‘openvas’ are all installed and would probably require reading the documentation extensively to understand the exact purpose of each. There are multiple methods for installing OpenVAS/GVM. We now run the following commands to fetch the Network Vulnerability Tests from OpenVAS Feed and sync the ‘scap’ and ‘cert’ data: These greenbone-nvt-sync and greenbone-scapdata-sync processes should take some time (depending on your internet speed). SecurityTrails Feeds™ Vulnerability scanning is one of the foundations of standard enterprise security. The omp client has a number of command line switches, but the XML is where the real power lies. One such product is OpenVAS (now renamed Greenbone Vulnerability Management or GVM). Vulnerability scanners, in particular, are critical for ensuring that any threats that may have made it past the firewall are picked up before they can infect and destroy entire networks. You should then see the dashboard of OpenVAS/GVM as shown here: Our first test will be to configure a simple scan using OpenVAS/GVM on a single IP address. The “Hosts” tab provides an overview of a short summary of the target IP/Host, the OS, Ports and Apps (not actually listing them but indicating how many). We’ll discuss the two most popular methods before proceeding with the installation. Choose the graph to add to your screen, for example, CPU Load. The enterprise/proprietary vulnerability scanner market is filled with competitors (such as QualysGuard or Nessus), and while some companies prefer running proprietary enterprise scanners, there are also many companies that prefer using collective intelligence and open source scanners. While pentesters and people doing bug bounties can use it as well, other available tools may be preferable, geared toward their areas of expertise. Lets first check that gsad is running and listening. gvmd --create-user=admin --password=admin Configure and Update Feeds (GVM) For the feeds to update completely, we will need to set “Feed Import Owner” to the admin’s UUID. We attempted a third scan using the subnet, but this time using one of the built-in Port Lists and setting the Scan Config to “Discovery”. Under the different options like NVT (Network Vulnerability Tests), CVE (Common Vulnerabilities and Exposure), CERT-Bund Advisories and more, you can browse through the listed items and click on each to provide a quick summary of the vulnerability/test/item.
