Threat modeling has two distinct, but related, meanings in computer security. The first is a description of the security issues the designer cares about. This is the sense of the question, "What is the threat model for DNSSec?" In the second sense, a threat model is a description of a set of security aspects; that is, when looking at a piece of software (or any computer system), one can define a threat model by defining a set of possible attacks to consider. It is often useful to define many separate threat models for one computer system. Each model defines a narrow set of possible attacks to focus on. A threat model can help to assess the probability, the potential harm, the priority etc., of attacks, and thus help to minimize or eradicate the threats. More recently, threat modeling has become an integral part of Microsoft's SDL (Security Development Lifecycle) process.[1] The two senses derive from common military uses in the United States and the United Kingdom.
