Which tool is commonly used to identify vulnerabilities in systems?

A vulnerability scanner is a specialized tool designed to identify and assess vulnerabilities in systems, applications, and networks. It works by actively scanning for known vulnerabilities, misconfigurations, and other security issues that could be exploited by attackers.

These scanners utilize databases of known vulnerabilities, often referred to as a vulnerability database, which is regularly updated to include the latest security flaws. By running a vulnerability scan, organizations can get a comprehensive view of their security posture and prioritize remediation efforts based on the risk associated with the identified vulnerabilities.

In contrast, tools such as firewalls and network switches primarily focus on controlling and managing network traffic. Firewalls act as a barrier to block unauthorized access while allowing legitimate communication. Network switches are used for connecting devices within the same network and do not provide direct security assessment capabilities. Packet sniffers monitor data packets traveling over the network but do not assess vulnerabilities; they are more focused on data analysis and traffic capture. Therefore, the unique functionalities of a vulnerability scanner make it the appropriate choice for identifying vulnerabilities in systems.
