Techopedia Explains Vulnerability Scanning

The downside of vulnerability scanning is that it can inadvertently result in computer crashes during the actual scan if the operating system views the vulnerability scan as invasive. Vulnerability scanners range from very expensive enterprise-level products to free open-source tools.

Types of vulnerability scanners include:

  • Port Scanner: Probes a server or host for open ports
  • Network Enumerator: A computer program used to retrieve information about users and groups on networked computers
  • Network Vulnerability Scanner: A system that proactively scans for network vulnerabilities
  • Web Application Security Scanner: A program that communicates with a Web application to find potential vulnerabilities within the application or its architecture
  • Computer Worm: A type of self-replicated computer malware, which can be used to find out vulnerabilities

Many antivirus software tools include vulnerability scanning features for home and business users today.
