This way the company network will remain safe against one of the most destructive cyber attacks. Therefore, by performing periodic network scans by Nessus, companies start to detect those one-day vulnerabilities as fast as possible and then patch them before they get exploited. The quicker this task is performed, the more secure your system will be. The only way to stop those kinds of attacks is by patching the systems directly once the patch is published by the vendor.
However, they are still straightforward compared to zero-day vulnerabilities and do not take too much time to get. Even those vulnerabilities are complicated to find and will require a high level of expertise from the attacker to successfully create a working exploit. In the one-day vulnerabilities, the attackers try to reverse engineer the patches produced by the vendors to find the vulnerabilities and exploit them. The one-day vulnerability is a type of security flaw discovered in software and its patch was released, but not all clients have applied the patches. Therefore, attackers tend to use the one-day vulnerabilities. However, those vulnerabilities are very expensive and require a very high level of security skills and dedication to successfully discover a vulnerability and create its exploit. Or due to the lake of education of the employees.įor the Zero-day vulnerabilities, there is basically no efficient solution to stop them.Most of the time companies get hacked due to one of the following security problems: Those vulnerabilities are discovered by cybersecurity researchers around the world every day and exploited by attackers. Each one of those components could easily be found vulnerable to a critical vulnerability. How can Nessus protect an enterprise?Īs you know the infrastructure of any company around the world is just a combination of multiple applications and network solutions. So let me explain in detail why vulnerability scanners are so important in a security program for enterprises and how they help secure them. This means I know exactly what their value is for companies. This task reduces the time between detecting the vulnerability and patching it, which also decreases the risk for the vulnerability to get exploited by attackers.Īs a penetration tester and a cybersecurity expert, dealing with vulnerability scanners is my daily work. Nessus protects enterprises by helping security teams to keep track of newly discovered vulnerabilities in their solutions. However, when talking about the technical benefits of a Nessus a lot of people still ask how can Nessus protect an enterprise? Nessus is one of the most popular ones among all the other vulnerability scanners in the market. One of the requirements to become compliant with known standards and laws in cybersecurity is to have a vulnerability scanner.
