Telesoft utilises the Nessus tool
Nessus is a vulnerability scanner that looks for potential security issues of a network/product. It detects common vulnerabilities via simulated attacks and looks for potential holes by methods such as carrying out port scanning, (this would detect issues such as an open port), and checking software to ensure that they are up to date with the latest security patches. A potential hacker would find it easy to run a vulnerability scan on a network, followed by a penetration test to exploit the vulnerabilities. It is therefore important to carry out these scans on a regular basis in order to keep the product/network secure.
It is important to note that this tool does not fix any issues, but it flags them up and shows a possible solution. This is very useful to engineering, as potential issues can be flagged up early and fixed before it has a chance to become a problem.
