Cybersecurity is the practice of protecting systems, networks, devices, and data from unauthorized access, digital attacks, or damage.
🛡️ The 3 Core Pillars (CIA Triad)
Every security architecture relies on three primary concepts:
- Confidentiality: Ensures sensitive data is accessible only to authorized users.
- Integrity: Protects data from being altered, deleted, or tampered with.
- Availability: Guarantees that systems, networks, and applications stay operational when needed.
Security is not a one-time setup or a single tool—it is a continuous process of securing your infrastructure and reducing the attack surface.
