Study Notes
ICS Cybersecurity Lifecycle
- Exida developed a white paper on the ICS cybersecurity lifecycle
- The paper highlights the growing threat of cyber-attacks on industrial control systems (ICS) impacting both industrial and national security
- Saudi Aramco's 2012 malware attack ("Shamoon") illustrated the devastating impact of these attacks (approximately 75% of workstations affected)
- Former Secretary of Defense Leon Panetta warned of cyberattacks as a potential national security threat, as destructive as 9/11
- The US Department of Homeland Security also issued alerts about coordinated attacks on gas pipelines.
What is the ICS Cybersecurity Lifecycle?
- A visual guide for ongoing cybersecurity practices
- Divided into three phases: Assess, Implement, and Maintain
- Encompasses the cybersecurity management program throughout the lifecycle
Assess Phase
- Scope Definition and Project Setup: Defines project parameters; identifies risks, roles and responsibilities; gathers pertinent information.
- Vulnerability Assessment: Identifying possible weaknesses in the system
- Risk Assessment: Analyzes vulnerability and determines risks, using a Cyber HAZOP (Hazards and Operability) method. Looks at consequences, and likelihood
- Document Requirements: Model the system; define, document, and list security requirements in the system (process zones, conduit model)
Implement Phase
- Conceptual Design: Strategy based on defense-in-depth
- Detailed Design: Focuses on validations and documentation of security implementation, countermeasures, and verification processes
- Test Planning & Acceptance Testing: Includes the development of test plans and abuse cases to test the system's security settings
Maintain Phase
- Countermeasure Maintenance and Security Monitoring: Continuous monitoring to ensure ongoing system security, and identify weaknesses. The implication of countermeasures is an ongoing process
- Incident Response Planning: Mechanism prior to a security incident is essential to address the security incident, if one occurs.
- Periodic Assessments: Evaluate and modify the system if necessary.
