Guide to Securing Critical Infrastructure from Cyber Threats

1. Introduction

• Importance of cyber security in critical infrastructure:
  • Protects essential services and systems from cyber threats.

2. Protective Measures

• Implementing protective measures for critical infrastructure:
  • Use firewalls, intrusion detection systems, and access controls.
  • Regularly update and patch systems to fix vulnerabilities.

3. Risk Assessments

• Conducting risk assessments for critical infrastructure:
  • Identify critical assets and potential threats.
  • Evaluate the impact and likelihood of cyber incidents.

4. Industrial Control Systems (ICS)

• Best practices for securing industrial control systems (ICS):
  • Use network segmentation to isolate ICS from other networks.
  • Implement strict access controls and monitoring.
• Using SCADA systems securely:
  • Secure SCADA systems with encryption and authentication.
  • Regularly update and patch SCADA software.

5. Energy Grid Protection

• Protecting energy grids from cyber threats:
  • Use advanced threat detection and response solutions.
  • Implement redundancy and failover mechanisms.

6. Incident Management

• Managing cyber security incidents in critical infrastructure:
  • Develop an incident response plan.
  • Train staff on recognising and responding to incidents.

7. Government Collaboration

• Collaborating with government agencies for critical infrastructure security:
  • Share threat intelligence and best practices.
  • Participate in public-private partnerships and initiatives.

8. Employee Education and Resilience

• Educating employees about critical infrastructure cyber security:
  • Provide regular training on security best practices.
  • Conduct drills and exercises to reinforce awareness.
• Implementing resilience measures for critical infrastructure:
  • Develop and test business continuity and disaster recovery plans.
  • Implement redundancy and failover mechanisms.
