The following classes and subclasses of information security can be distinguished

Information security threats

1. Vulnerability analysis
2. Classes and attributes of threats

Security policies and models

1. Theoretical and informational models
2. Mandate systems

International standards

Information properties as an object of protection

2. Principles of information security of the state
3. Security models and policies
4. International standards in the field of information security

Thus, summarizing the sections of information security, we can distinguish

• classes of information security threats
• security policies and models
• international standards with security criteria.

Threat classes include system vulnerability analysis and threat classification by attribute. Security policies and models include theoretical-information models and mandated systems. International information security standards include security criteria, information security classes (C1, C2), and mandate protection.
