A network vulnerability assessment is a test to verify how secure the data is on your network. It helps find any vulnerabilities in your infrastructure, and it helps prevent hackers from getting into your system. Although some confuse this assessment with penetration testing, there is a difference. The vulnerability assessment is not invasive to the point of exploiting any weaknesses found.
Levels of Assessment
External testing looks at the servers, infrastructure, and installed software. It gets a basic blueprint of how the server is running and how it delivers data. This is the first area that hackers see; it can be accessed by non-trusted individuals fairly easily. However, the information that hackers gain from this outward view can be crucial. It allows them to look up existing known hacks specific to the operating system, network, or software. This can give the hacker an easy way in to the server’s internal workings.
Internal testing verifies the safety of network nodes and looks deeper into third-party proprietary software. Both the external and internal testing can typically be performed using software.
Wireless testing verifies that the protocols set forth are secure and helps to minimize its use in a corporate setting when it is not required.
According to the Community ENTerprise Operating System (CentOS) website, it is vital to implement the network vulnerability assessment into the IT methodology. The assessment is not a test that should be performed once and then forgotten about. Assessment should be an ongoing practice. As hackers continually find new ways to break into secure servers, IT departments must continually find ways to stop them.
It is a good idea to perform the assessment in-house instead of hiring a third-party company. It gives the IT personnel more experience with the procedure and will help them to learn how to find signs of a break-in. Talk to third-party vendors to find the right software tools for your business, and make sure they teach your employees all the intricacies of their software.
