Network Security - Security Ontologies & Policy Modeling

Security ontology is a structured way to represent security knowledge and policies.

What it does

• Defines relationships between:

  • Assets

  • Threats

  • Vulnerabilities

  • Controls

• Enables automated reasoning

Why it is important

• Modern networks are complex

• Manual policy management causes errors

• Helps in consistency and compliance

Example

A policy engine automatically determines whether a user can access a resource based on role, device, and context.
