Nessus vs burp suite3/28/2023 Server or network-based vulnerability scanners run vulnerability scans from a single device or host. Here’s a quick look at both of them: Server-based Vulnerability Scanners There are two main types of vulnerability scanners, server-based and agent-based vulnerability scanners. So if a device on your network is running an outdated version of Apache, the vulnerability scanner will list out the vulnerabilities that are known for that version of Apache. and compares this information with a database or multiple databases which contain known vulnerabilities. The vulnerability scanner then takes this information and compares the information it was able to collect, such as operating system, operating system version, open ports, running services, etc. If a vulnerability scanner is scanning your network, it should be able to detect which devices are running Windows and which are running a Linux Distribution. Each operating system will respond to packets sent to them in a slightly different way, and using these differences, the vulnerability scanner can then profile those devices. These applications communicate with these devices and then pull in information about them based on the responses they receive.Īn example of this is operating system identification. Vulnerability scanners do this by trying to communicate with any device they are targeted at-whether that is a single device or an entire network. Without getting too in-depth, a vulnerability scanner is just an application that automatically tries to collect information about the devices it interacts with. Since we covered the basics in our vulnerability scanning guide, in this article, we thought we’d go over the two main types of vulnerability scanners, some common options among our customers and IT professionals, and reasons why you may prefer one over the others. Vulnerability scanning is a key control within frameworks like SOC 2, ISO 27001, NIST 800-53, and can even apply to privacy-centric standards like GDPR.
