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:
1.) Secure Boot Process
- 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.
2.) User Authentication and Authorization
- Authentication verifies the identity of users, while authorization determines their access to system resources.
3.) Encryption and Data Protection
- Encryption protects data at rest and in transit by converting it into an unreadable format that requires a key for decryption.
4.) Regular Security Updates and Patch Management
- Regularly updating software and operating systems to fix vulnerabilities and mitigate threats.
5.) Secure Configuration
- Ensuring that systems are configured securely by disabling unnecessary features and services to reduce the attack surface.
6.) Intrusion Detection and Prevention
- Detecting and preventing unauthorized activities within the system or network.
7.) Secure Communication
- Ensuring that data transmitted over networks is protected from eavesdropping and tampering.
8.) Endpoint Security
- Protecting individual devices (endpoints) like desktops, laptops, and mobile devices from threats.
9.) Security Auditing and Monitoring
- Continuously reviewing system activities and configurations to detect security issues and ensure compliance.
10.) User Education and Awareness
- Educating users about security best practices to prevent human errors that could lead to security breaches.
11.) Incident Response Plan
- A predefined strategy for responding to and mitigating the impact of security incidents.
