What is Cybersecurity
Cybersecurity is the practice of protecting systems, networks, and data from unauthorized access and attacks.
Key Concepts
- Confidentiality: data must be accessible only to authorized users
- Integrity: data must remain accurate and unaltered
- Availability: systems must be accessible when needed
👉 This model is known as the CIA triad
Additional Concepts
- Authentication
- Authorization
- Accounting
Why it matters
These concepts are fundamental for:
- security systems
- certifications like ISC2 CC
- real-world cybersecurity roles
Example
A system that requires login (confidentiality), protects data from changes (integrity), and stays accessible (availability) follows core security principles.
