What actions can a threat agent take against an asset?

The actions that a threat agent can take against an asset are focused on malicious intent and the exploitation of vulnerabilities. Accessing an asset allows the threat agent to gain unauthorized entry, potentially leading to the exposure of sensitive information. Disclosing means revealing or exposing that information to unauthorized individuals or entities, which can cause data breaches and loss of confidentiality. Modifying refers to altering the information or state of the asset, which can lead to misinformation or corruption of data, impacting its integrity.

In the context of computer security, these actions are critical to understand because they highlight the methods through which threats can harm an organization or individual, emphasizing the need for robust security measures to protect against such actions. The other options, while relevant to the broader field of information security, do not pertain specifically to the harmful actions that a threat agent can execute against an asset. They typically involve protective or administrative measures rather than adversarial actions.
