Define the OSI security architecture

Answer 1

The OSI security architecture is a framework that outlines the principles and components necessary for ensuring security in information systems based on the Open Systems Interconnection (OSI) model. It identifies security threats, vulnerabilities, and countermeasures across different layers of the OSI model, providing a structured approach to implementing security mechanisms. The architecture emphasizes the importance of confidentiality, integrity, availability, authentication, and non-repudiation while facilitating communication between diverse systems. Overall, it serves as a guideline for designing and implementing security measures in networked environments.
