Core cybersecurity concepts every professional should know.
The CIA Triad defines the three pillars of information security: Confidentiality, Integrity, and Availability, providing the universal framework for risk assessment and control design.
Defense in Depth layers multiple overlapping security controls across physical, network, host, application, and data tiers so that no single point of failure leads to total compromise.
Zero Trust Architecture eliminates implicit trust, requiring continuous verification of every user, device, and connection before granting access to any resource.
Threat modeling systematically identifies and prioritizes potential threats to a system using structured methodologies like STRIDE, enabling teams to address design-level security flaws before deployment.
Risk assessment systematically identifies, analyzes, and prioritizes cybersecurity risks to guide security investments and compliance requirements.
