Final answer:
Performing vulnerability assessments for a client is not considered a computer crime; instead, it's a legitimate part of maintaining network security.
Step-by-step explanation:
Computer crimes typically include activities that involve illegal activities using a computer or network as a tool, target, or place of criminal activity.
Examples of such crimes are fraud via manipulation of computer records, sending spam, and deliberate avoidance of computer security systems. However, not all activities that involve a computer are considered criminal. One such activity is performing vulnerability assessments for a client, which is a legal and often necessary task for ensuring the security of a computer system. Instead of being a crime, it is a legitimate part of maintaining the integrity and security of networks.
