Operating System Security (OPSEC) Practice Exam

During the execution phase of a virus, the virus effectively carries out its intended actions. This means that once the virus has successfully infiltrated a system and is allowed to execute, it performs the tasks that it was designed to do, which can include corrupting files, stealing sensitive information, or enabling backdoor access for further exploitation.

In this context, the execution phase is critical because it is the point at which the harmful effects of the virus are realized. The consequences of these actions can lead to significant damage to the integrity, confidentiality, and availability of data and system resources.

While other phases mentioned, such as entering a dormant state or spreading, are relevant to the lifecycle of a virus, they do not describe the actual execution phase where the malicious actions take place. Additionally, deletion of the virus from the system suggests a removal process rather than an execution, which does not align with the definition of what happens during this particular phase in a virus’s lifecycle.
