Trusted Computer System Evaluation Criteria
The Trusted Computer System Evaluation Criteria (TCSEC), also known as the Orange Book, is a set of standards from the 1980s for assessing the security of computer systems. It categorizes systems based on their ability to protect sensitive information through features like access controls and accountability. Systems are rated from basic (minimal protection) to high assurance levels, ensuring they meet specific security requirements. The goal is to help organizations choose and develop systems that maintain data confidentiality, integrity, and controlled access, providing a structured approach to security evaluation.
