    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.
