Vulnerability Scanner: Key Features and Things to Bear in Mind When Choosing One

By CIOReview | Saturday, October 30, 2021

Vulnerability scanners can detect and catalog all network access points and linked devices, then compare the scan results to a database of known vulnerabilities.

FREMONT, CA:Vulnerability scanning, assessment, and management all follow the same basic cybersecurity principle: if the cybercriminals do not have a way in, they cannot get in. For that reason, scanning for vulnerabilities and subsequently patching them, often via a patch management system, is a critical IT security practice.

Vulnerability scanning technologies can help by locating and even fixing vulnerabilities for you, easing the burden on security personnel and operations centers. Vulnerability scanners identify and classify system flaws to prioritize patches and, in some cases, anticipate countermeasure efficacy. Scans can be performed in-house or by a third-party service provider.

Vulnerability management is an extensive offering that includes vulnerability scanning and breach and attack simulation is a complementing technology that enables ongoing automated vulnerability evaluation. Vulnerability scanners are software that look for, identify, and evaluate known flaws in networks and network resources. They detect and catalog all network access points and linked devices, then compare the scan results to a database of known vulnerabilities. These tools can also detect irregularities in packet formation and possible paths to vulnerable applications or scripts.

Vulnerability Scanners' Key Features

Identification and correlation, and evaluation are two of the most critical functions of vulnerability scanning software.

Identification and Correlation: Vulnerability scanners identify and classify networked devices, open ports, operating systems, and software, then compare this data to the most recent known vulnerabilities. Misconfigurations and a lack of security controls and policies can also be detected.

Evaluation: These tools examine and assess the amount of risk for each vulnerability after discovering it. They can also undertake root cause analysis to figure out what is causing the problem. This data helps determine which vulnerabilities should be prioritized.

How to Choose a Vulnerability Scanner                                      

There are three things to bear in mind when looking for a vulnerability scanning tool:

  • Make sure it can develop compliance guidelines based on the company's policies and requirements.
  • To help prioritize patching efforts, choose a tool with an accessible dashboard that displays risk scores and data.
  • Also, choose one that can scan the most important systems and defenses.
