Spoofing threats are usually associated with a wily hacker being able to impersonate a valid system user or resource to get access to the system and thereby compromise system security.

Tampering with data involves the malicious modification of system or user data with or without detection.

Repudiation threats are associated with users—malicious or otherwise—who can deny performing an action without administrators having any way to prove otherwise. An example of a reputability threat is a user performing an illegal operation in a system that lacks the ability to trace such operations.

Information disclosure threats involve the compromising of private or business-critical information through the exposure of that information to individuals who are not supposed to see it.

Denial of service (DoS) threats when carried out deny service to valid users—for example, by making the system temporarily unavailable or unusable or by forcing a reboot or restart of the user’s machine.

Elevation of privilege: In this type of threat, an unprivileged user gains privileged access and thereby has sufficient access to compromise or destroy the entire system.
