A threat is a possible danger that might exploit a vulnerability to breach the security and cause harm to an asset. An asset is anything of value that needs to be protected, such as data, systems, or networks. A vulnerability is a weakness or flaw in the security that can be exploited by a threat. An exploit is a piece of code or a technique that takes advantage of a vulnerability to compromise the security and perform malicious actions on an asset.
