Here’s a summary of the technical security protection mechanisms:
- Abstraction: Hides the internal details of an object or component, exposing only what is necessary for users to interact with it. This principle is fundamental in object-oriented programming and allows for simpler and more secure interactions with complex systems.
- Separation of Privilege: Enhances security by requiring multiple conditions or permissions to perform a sensitive operation. Instead of granting broad access, it assigns specific rights for each privileged operation, minimizing the risk of unauthorized access.
- Process Isolation: Ensures that each process operates in its own separate memory space, preventing it from accessing or interfering with other processes. This is crucial for maintaining the integrity and security of processes in a multi-user environment.
- Layering Processes: Applies a hierarchical structure to operating system processes, similar to the ring model used for operating modes. This layered approach helps in managing and enforcing security policies and permissions.
- Hardware Segmentation: Uses physical hardware mechanisms to enforce memory and process isolation, as opposed to relying solely on operating system controls. This provides an additional layer of security by physically segregating processes and data.
