Unauthorized Change

Definition: An unauthorized change in your computer or computer network can cause serious problems to arise. The very act of departing from a known condition by altering computer or network settings without foreknowledge of the probable results is reckless and negligent. Information systems require stability and should produce the same results given a known set of values. Known performance attributes are basic to information security. If parameters are altered the confidentiality, integrity and availability of information can be compromised.

Its Relevance: Information security is based upon knowledge of how the system should perform. If a critical value associated with the computer or network is made distinctly different from an established baseline the viability of the information plan can instantly called into question. The continuity of business operations is at risk.
