Techopedia Explains Graduated Security

Graduated security primarily enables classifying the security requirements of an individual computing system or an entire IT environment. The different layers of graduated security are:

  • Low: When the system security is of low priority or when it is least prone to any vulnerability.
  • Moderate: The system/IT environment requires a medium level of information security.
  • High: System/infrastructure requires a higher level of security and protection.
  • Top-secret: Typically used for military and government IT systems, it is the highest level of security that can possibly be implemented.
