Vulnerability scanner

A vulnerability scanner is a type of computer program specifically designed to search a given target (piece of software, computer, network, etc.) for weaknesses. The scanner systematically engages the target in an attempt to assess where the target is vulnerable to attack . The program can be used either prophylactically (to find holes and plug them before they are exploited) or maliciously (to find holes and exploit them).

Types of vulnerability scanners: *port scanners, computer virus, computer worm
