Fundamental Concepts

Key Concepts:

1. Confidentiality, Integrity, and Availability (CIA):

   • Confidentiality: This principle ensures that sensitive information remains confidential and is only accessible to authorized individuals or systems. It prevents unauthorized access or disclosure of data.
   • Integrity: Data integrity ensures that information remains accurate and reliable. It guards against unauthorized alterations or tampering with data.
   • Availability: Availability ensures that systems and data are accessible when needed. It safeguards against disruptions or downtime that could impact operations.

2. Security Layers:

   • Effective cybersecurity often relies on a layered approach. Multiple layers of security measures are implemented to provide defense in depth. These layers can include:
     • Physical Security: Protecting physical access to computer systems and data centers.
     • Network Security: Safeguarding network infrastructure and data transmission.
     • Endpoint Security: Securing individual devices like computers, smartphones, and IoT devices.
     • Application Security: Protecting software applications from vulnerabilities and attacks.
     • Data Security: Ensuring the confidentiality and integrity of data.
     • Identity and Access Management (IAM): Controlling and managing user access to systems and data.

Understanding these fundamental concepts forms the basis for implementing robust cybersecurity measures. In the following sections of this documentation, we will delve deeper into each concept, exploring best practices and strategies to apply them effectively.
