Vulnerability Scan Analysis
Using a free vulnerability scan analysis service is a great way to learn more about your network’s security vulnerabilities. Using these services allows you to understand where your security risks are, and how to mitigate them. These assessments are performed by vulnerability experts who probe the internet to find recent vulnerabilities, threats, and mitigation patches. They then map the vulnerability information to the appropriate patches. A vulnerability scanner’s most integral function is to map vulnerabilities to relevant patches.
Vulnerability scanners perform a vulnerability assessment by identifying security loopholes in your network and infrastructure. This can take a long time to do manually, and vulnerability scanners help you save a great deal of time by detecting the most common issues and highlighting solutions for those vulnerabilities. These tools also provide an analysis report with a summary of the findings, as well as a remediation plan.
OpenVAS is an open source software framework that is capable of performing a large-scale vulnerability scan. It can find vulnerabilities in web applications, databases, operating systems, networks, and virtual machines. It supports Linux and receives updates daily, and it is free to use. The free version has a steep learning curve, but it is well-worth it for the amount of information it can provide.
The best free vulnerability scanners offer more than just a basic report. These services include advanced scanning engines and customizable reports. Acunetix, for example, uses a unique scanning engine and provides detailed reports. It can scan websites for more than 4500 vulnerabilities and has a low false-positive rate. It also allows you to configure workflows and offers a visually appealing interface.

Another free vulnerability scanner is Nikto, which uses multiple protocols to scan a web server. This scanner is compatible with Windows, Mac, and Linux and has a full HTTP proxy. The downside of this tool is that it can sometimes return false positives, but this is due to the extensive testing it goes through. Besides Nikto, you can also use Wireshark, an open source network protocol analyzer. The open source version of this software runs on various platforms and offers a flexible scripting language. It also comes with patching assistance.
There are two types of vulnerability scan tools available: authenticated scans and unauthenticated scans. Authenticated scans require the tester to log in as a network user. The purpose of this feature is to find any vulnerabilities that can be accessed by an unauthorized user. This makes the scanning process more efficient and comprehensive.
If you’re looking for an on-premise vulnerability scanner, you can use Nexpose. It is a real-time vulnerability scanner that can scan a wide range of network infrastructures. It also allows you to prioritize vulnerabilities according to their age, vulnerability impact, and exploit kit usage. Another advantage of this free vulnerability scanner is that it has an open API that allows you to easily create attack surface maps.
