What are the different types of security models?

Security Models

• State Machine Model. The state machine model is based on a finite state machine, as shown in Figure 5.6.
• Information Flow Model.
• Noninterference Model.
• Confidentiality.
• Integrity.
• Other Models.

What is a security architecture model?

While security architecture has many definitions, ultimately it is a set of security principles, methods and models designed to align to your objectives and help keep your organization safe from cyber threats. Security architecture translates the business requirements to executable security requirements.

What is the best security architecture?

Several frameworks exist for security architecture, the most important ones are SABSA, O-ESA and OSA. They complement and overlap each other.
