Student Guide (IB Design Technology)

Simple Explanation: Smart grids, which are like upgraded power grids, need extra security to protect them from hackers. Intrusion detection systems act like a security guard that watches for bad guys and stops them, even if they get past the main locks.

Why This Matters: Understanding how security systems like IDPS work is crucial for designing any system that handles sensitive data or controls critical infrastructure, ensuring it is safe and reliable.

Critical Thinking: While IDPS are presented as a strong countermeasure, what are the potential drawbacks or limitations of relying heavily on these systems, such as the risk of false positives or the computational overhead they might introduce in real-time applications?

IA-Ready Paragraph: The integration of intrusion detection and prevention systems (IDPS) is vital for enhancing the security and resilience of smart grid infrastructure. As demonstrated by research analyzing numerous case studies, IDPS serve as a critical secondary defense mechanism, effectively detecting and mitigating cyber threats that may bypass primary security protocols such as encryption and authorization. This layered security approach is essential for maintaining the operational continuity and reliability of smart grid components like AMI and SCADA systems.
