vulnerability scanning Last modified: Tuesday, August 27, 2002

The automated process of proactively identifying vulnerabilities of computing systems in a network in order to determine if and where a system can be exploited and/or threatened. While public servers are important for communication and data transfer over the Internet, they open the door to potential security breaches by threat agents, such as malicious hackers. Vulnerability scanning employs software that seeks out security flaws based on a database of known flaws, testing systems for the occurrence of these flaws and generating a report of the findings that an individual or an enterprise can use to tighten the network’s security. Vulnerability scanning typically refers to the scanning of systems that are connected to the Internet but can also refer to system audits on internal networks that are not connected to the Internet in order to assess the threat of rogue software or malicious employees in an enterprise.

Security Scanning Is Not Risk Analysis Many IT decision makers assume that performing a security vulnerability assessment is the same thing as risk analysis. However, these two processes are very different. (2002)
