- Confinement
- Definition: Restricting the actions of a program to specific memory locations and resources.
- Purpose: Prevents a process from accessing unauthorized areas of memory or resources, ensuring that it can only interact with what it is explicitly permitted to.
- Also Known As: Sandboxing, where a process operates in a restricted environment to prevent it from affecting other processes or the broader system.
- Bounds
- Definition: The limits set on the memory addresses and resources that a process can access.
- Purpose: Defines the area within which a process is confined, ensuring that it cannot exceed its allocated boundaries. This helps in preventing a process from interfering with other processes or system resources.
- Isolation
- Definition: Running a process in a way that enforces access bounds, ensuring it operates independently of other processes.
- Purpose: Ensures that any actions or behavior of the isolated process affect only its own memory and resources, thereby preventing unintended or malicious interference with other processes or the system.
These techniques are fundamental for maintaining the security of systems by ensuring that processes operate within defined boundaries, preventing unauthorized access or interference, and protecting the integrity of system operations. Understanding these concepts is crucial for ensuring CIA, particularly in secure system design and implementation.
