Comparative Performance of HRL Agents vs. Static
| Method | Damage | Cost | FPs | FNs |
|---|---|---|---|---|
| Static | 3.1314 | 0.214069 | 0.9816 | 0.997 |
| Option-Critic Multiple Heads | 0.01 | 0.1968 | 0.4345 | 0.43650 |
| h-DQN Separate Rewards | 0.8319 | 0.06333 | 0.9998 | 0.9997 |
The Option-Critic with Multiple Heads demonstrates superior performance, significantly reducing damage and false negatives compared to both static and other HRL methods.
Real-time Adaptive Threat Mitigation
The Multi-Option Critic HRL agent demonstrated a significant reduction in active cyber threats, as illustrated by dynamic incident indicator reduction (Figure 13). This validates its superior adaptive response capabilities compared to static methods, ensuring continuous protection for critical industrial infrastructure and preventing persistent cyber incidents.
