Strategy C: The "Survey" Paper
What “Patched PDF” Means
The Clark-Wilson model is a practical security model that focuses on commercial and business applications. The model consists of three primary components:
- Cloud Extensions: Bell-LaPadula does not handle shared tenancy in AWS or Azure.
- Zero Trust: Traditional models were perimeter-based. The modern "Zero Trust" model (Never trust, always verify) patches the assumptions of the old Biba model.
- Data Breaches: The 1990s models assumed physical control over terminals. Patched models now account for remote injection attacks and side-channel attacks.
- Conduct a thorough risk assessment: Identify potential security risks and prioritize them based on likelihood and impact.
- Develop a comprehensive security plan: Outline the security controls and measures to be implemented, including patching and vulnerability management.
- Establish a security governance structure: Define roles and responsibilities for security management and oversight.
- Provide ongoing security awareness training: Educate employees on security best practices and the importance of patching.
- Continuously monitor and evaluate security controls: Regularly assess the effectiveness of security measures and make updates as needed.
