9. Implement security mechanisms tailored for real-time and embedded systems.
Real-time and embedded systems require security mechanisms that are efficient, lightweight, and deterministic due to their deployment in critical environments. These systems face unique challenges such as limited resources, real-time constraints, and long lifecycles. Key security goals include confidentiality, integrity, and availability, while the implementation of security mechanisms like secure boot and memory protection are essential to safeguarding these systems.

What we have learnt
- Real-time and embedded systems demand lightweight, deterministic, and robust security solutions.
- Key security goals are confidentiality, integrity, availability, authentication, and authorization.
- Effective security mechanisms include secure boot, memory protection, and cryptography.
- Security in RT/embedded systems involves both software solutions and hardware features for resilience.
Key Concepts
- -- Secure Boot
- Mechanism that ensures only verified and signed firmware is loaded to prevent tampering.
- -- Memory Protection
- Uses Memory Protection Units (MPUs) or Memory Management Units (MMUs) to isolate tasks and protect memory regions.
- -- Cryptography
- Techniques used for encrypting data, ensuring message integrity, and establishing secure communications.
- -- RealTime Constraints
- Requirements that ensure security operations do not violate the timing needs of the real-time system.
- -- Intrusion Detection
- Systems that monitor for unauthorized access or anomalies within a device or network.
