Protect Systems
Secure servers, endpoints, networks, and cloud infrastructure to keep environments reliable and controlled.
Core Idea of Cybersecurity
Foundation concept for security awareness and architecture decisions.
Cybersecurity is protecting systems, applications, and data from unauthorized access, manipulation, or disruption.
Protect Applications
Build and run software with secure coding, patching, testing, and access controls to reduce exploit paths.
Protect Data
Use classification, encryption, backup, and monitoring to preserve confidentiality, integrity, and availability.
CIA Triad
The foundation for all security decisions:
CCia Triad
Confidentiality
Only the right people/systems can see data.
Example: Prevent cross-tenant data leaks in a SaaS CRM/HRMS.
ICia Triad
Integrity
Data and actions cannot be altered incorrectly.
Example: Prevent salary approval, role changes, or order edits via token tampering or bypass.
ACia Triad
Availability
Systems must stay usable and resilient.
Example: Protect APIs from DDoS, brute force, and resource exhaustion.
