To perform risk assessment: Identify risk areas → Analyze likelihood and impact → Develop innovative mitigation strategies → Implement controls → Review and adjust; Provide 5 examples of technical and safety risks and apply these steps

Risk Assessment Process with Examples

Steps for Risk Assessment:

1. Identify Risk Areas: Recognize potential technical or safety risks.
2. Analyze Likelihood and Impact: Evaluate the probability of occurrence and the severity of consequences.
3. Develop Innovative Mitigation Strategies: Devise creative and practical ways to reduce or eliminate risks.
4. Implement Controls: Apply the mitigation strategies.
5. Review and Adjust: Monitor the effectiveness of controls and refine as needed.

Examples and Application of Risk Assessment

1. Cybersecurity Breach in Software Systems

• Identify Risk Areas: Unauthorized access to sensitive data due to weak encryption.
• Analyze Likelihood and Impact: High likelihood due to frequent attacks; severe impact includes data loss and reputational damage.
• Develop Mitigation Strategies:
• Use quantum-resistant encryption algorithms.
• Implement multi-factor authentication (MFA).
• Deploy AI-based intrusion detection systems (IDS).
• Implement Controls: Encrypt all sensitive data, enforce MFA, and deploy IDS across the network.
• Review and Adjust: Continuously monitor IDS logs and update encryption standards as threats evolve.

2. Hardware Failure in Safety-Critical Systems

• Identify Risk Areas: Failure of a redundant control unit in an aircraft system.
• Analyze Likelihood and Impact: Low likelihood due to redundancy; catastrophic impact if failure occurs during flight.

• Develop Mitigation Strategies:
• Design triple redundancy instead of dual redundancy.
• Use predictive maintenance with IoT sensors to detect early signs of wear.
• Implement Controls: Install sensors to monitor key hardware metrics and perform regular diagnostic tests.
• Review and Adjust: Periodically review failure data and adjust maintenance schedules.

3. Battery Overheating in Electric Vehicles

• Identify Risk Areas: Overheating due to thermal runaway in lithium-ion batteries.
• Analyze Likelihood and Impact: Medium likelihood under extreme operating conditions; impact includes fire and safety hazards.
• Develop Mitigation Strategies:
• Integrate active cooling systems with AI to predict overheating.
• Use solid-state batteries with lower thermal runaway risk.
• Implement Controls: Enhance battery management systems (BMS) with AI and deploy real-time thermal sensors.
• Review and Adjust: Monitor temperature trends and recalibrate the cooling system algorithms.

4. Human Error in Software Development for Safety-Critical Applications

• Identify Risk Areas: Mistakes in code implementation for man-rated spacecraft software.
• Analyze Likelihood and Impact: Medium likelihood due to complexity; high impact with potential mission failure.
• Develop Mitigation Strategies:
• Automate testing and validation using generative-AI.
• Enforce strict peer-review and coding standards.
• Implement Controls: Integrate automated code scanning tools and establish mandatory reviews.
• Review and Adjust: Audit code regularly and refine automated tools based on past errors.

5. Structural Failure in a Bridge Under Dynamic Load

• Identify Risk Areas: Structural fatigue due to unexpected load conditions or material degradation.
• Analyze Likelihood and Impact: Medium likelihood depending on location; catastrophic impact if failure occurs.
• Develop Mitigation Strategies:
• Employ sensors to monitor real-time stress and strain.
• Design adaptive load redistribution mechanisms.
• Implement Controls: Install monitoring systems and reinforce high-stress areas with advanced materials.
• Review and Adjust: Analyze sensor data and perform frequent inspections to address emerging issues.
