As a result, the scan can cause issues such as errors and reboots, reducing productivity. Running a vulnerability scan can pose its own risks as it is inherently intrusive on the target machine’s running code. The scanner software attempts to exploit each vulnerability that is discovered. The software compares details about the target attack surface to a database of information about known security holes in services and ports, anomalies in packet construction, and potential paths to exploitable programs or scripts. Vulnerability scans are also used by attackers looking for points of entry.Ī vulnerability scanner runs from the end point of the person inspecting the attack surface in question. An Approved Scanning Vendor (ASV), for example, is a service provider that is certified and authorized by the Payment Card Industry (PCI) to scan payment card networks. A scan may be performed by an organization’s IT department or a security service provide, possibly as a condition imposed by some authority. Vulnerability scanning is an inspection of the potential points of exploit on a computer or network to identify security holes.Ī vulnerability scan detects and classifies system weaknesses in computers, networks and communications equipment and predicts the effectiveness of countermeasures.
