Model of Secure System

A secure system is designed to ensure the confidentiality, integrity, and availability of data and resources while protecting against internal and external threats.

Below are the key components:

  • The secure boot process ensures that the system starts in a trusted state by verifying the integrity of the operating system and firmware before execution.
  • Authentication verifies the identity of users, while authorization determines their access to system resources.
  • Encryption protects data at rest and in transit by converting it into an unreadable format that requires a key for decryption.
  • Regularly updating software and operating systems to fix vulnerabilities and mitigate threats.
  • Ensuring that systems are configured securely by disabling unnecessary features and services to reduce the attack surface.
  • Detecting and preventing unauthorized activities within the system or network.
  • Ensuring that data transmitted over networks is protected from eavesdropping and tampering.
  • Protecting individual devices (endpoints) like desktops, laptops, and mobile devices from threats.
  • Continuously reviewing system activities and configurations to detect security issues and ensure compliance.
  • Educating users about security best practices to prevent human errors that could lead to security breaches.
  • A predefined strategy for responding to and mitigating the impact of security incidents.
