![]() For example, they can automatically block potentially dangerous IP addresses or close open ports that may provide an entry point for attackers. Some active scanners act autonomously to resolve discovered security issues. This information gives security admins an overview of ongoing processes and lets them check the health of systems on the entire network. This includes basic information such as device name, IP address, and more detailed configuration information such as: These tools provide critical information about devices. The Benefits of Active Vulnerability ScannersĪctive scanners are especially useful when the organization needs constant vigilance to keep threat actors out. The goal is to uncover the security gaps in the network that a hacker could exploit.Īdministrators may also use active scanners to examine an enterprise resource after an attack, to understand how an attacker got past existing defenses. By using known attacks against one or more selected targets, they try to do what a potential attacker may do to compromise the organization and its resources. Security teams use active scanners to simulate attacks on the network. It then examines the responses received from these nodes to assess which node represents a weak point. What is an Active Vulnerability Scanner?Īn active vulnerability scanner sends transmissions of “test traffic” to the nodes or endpoints on the enterprise network. Your security team reviews this information to understand which weaknesses need attention and then take appropriate action to address them, before a damaging breach or operational disruption happens. The scanner next flags discovered vulnerabilities in a report. It then searches for known vulnerabilities in a vulnerability database such as the NVD and assesses whether any vulnerability from this database exists in your enterprise environment. How Does a Vulnerability Scanner Work?Ī vulnerability scanner creates an inventory of all the systems and devices that make up the enterprise attack surface. Keep in mind that a vulnerability management program includes both automated vulnerability scanning to identify vulnerabilities and manual vulnerability assessments to categorize, rank, investigate, and remediate vulnerabilities in order of priority. The best scanners provide full coverage of your environment and help you understand the complete picture of your organization’s security posture. It is part of a broader vulnerability management program aimed at protecting the organization from cyberattacks and data breaches.Ī vulnerability scanner is a tool that automatically searches for and reports on open network security vulnerabilities. Vulnerability scanning is the process of looking for and finding cybersecurity vulnerabilities on an enterprise network, system, or device.
