I have chosen Discretionary access control as my topic from the given Key terms and I will give an explanation about Discretionary access control and also how it fits in to the overall Access Control concept step by step below:
1. The Discretionary access control is nothing but it is a type of the access control which is defined by the Trusted Computer System Evaluation Criteria.
2. The Discretionary access control is used for restricting access to the objects based on the identity of subjects and also groups to which they belong.
3. The Discretionary Access Control (DAC) is a nothing but it is a type of access control in which a user has complete control over all the programs it owns and executes.
4. The Discretionary Access Control (DAC) also determines that the permissions other users have those those files and programs. Because DAC requires permissions to be assigned to those who need access
5. The Discretionary Access Control (DAC) is commonly called described as a need-to-know access model.
6. Generally the access control is nothing but the identification, authorization and authentication of the users for an systems.
7. so from the above point it is very clear that The Discretionary Access Control (DAC) fits into the overall Access Control concept.
