Vulnerability scanning detects and classifies system weaknesses in computers, networks, and communications equipment in order to predict the effectiveness of established countermeasures. Vulnerability scanning lets you take a proactive approach to close any gaps and maintain strong security for your systems, data, employees, and customers.
A vulnerability scan may be performed by an organization’s own IT department or a third-party security service. In some cases, vulnerability scans can be a condition imposed in order to maintain security compliance. For example, an Approved Scanning Vendor (ASV) is certified and authorized by the Payment Card Industry (PCI) to scan payment card networks and is a condition of maintaining PCI compliance. Vulnerability scans are also a frequent tool of cybercriminals looking for points of entry to exploit.
Data breaches are often the result of unpatched vulnerabilities, so identifying and eliminating these security gaps removes that potential attack route from hackers.
