The Drawbacks of Active Vulnerability Scanners They also raise alerts so administrators can take action to close vulnerabilities before bad actors can attack. 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. More than 75 percent of software applications have security flaws that open the door to breaches.On average, companies take more than 60 days to remediate internet-facing vulnerabilities.84 percent of organizations have high-risk vulnerabilities on their external networks.You need a vulnerability scanner to seek out and remediate vulnerabilities because: How do these different types of scanners work? And which type does your organization need? Read on to discover the answers. Vulnerability scanners can be active or passive. This plan includes a reliable vulnerability scanner. For this, you need a robust vulnerability management plan. To stay safe, you must continually identify, classify, mitigate, and remediate the open vulnerabilities on your network and systems. government’s National Vulnerability Database ( NVD) has almost 98,000 vulnerabilities classified as “critical,” “high,” or “medium.” These vulnerabilities represent threats that can genuinely damage your organization. Bad actors may take advantage of security misconfigurations, broken authentication processes, buffer overflows, and other vulnerabilities to spread malware, launch account takeover attacks, and steal large amounts of sensitive data.Īs of April 2022, the U.S. Vulnerabilities in enterprise environments create many opportunities for cyber criminals to attack the organization.
