The CIA Triad (Confidentiality, Integrity, Availability): Balancing the three pillars of security—ensuring sensitive data remains private (Confidentiality), verifying that data has not been modified or corrupted (Integrity), and keeping critical systems accessible to authorized users when needed (Availability).
The AAA Framework (Authentication, Authorization, Accounting/Auditing): Implementing identity workflows by verifying who a user is (Authentication), establishing what resources they are permitted to access (Authorization), and keeping detailed logs of their activities for security reviews and compliance (Accounting).
Principle of Least Privilege (PoLP): Enforcing the security practice of restricting user, application, and service account permissions to only the absolute minimum necessary to perform their designed functions.
Separation of Duties (SoD): Designing workflows that split critical, high-risk tasks among multiple personnel, preventing single points of human failure, collusion, and insider fraud.
Zero Trust Architecture (ZTA): Moving away from perimeter-centric defenses to an identity-centric model based on the core tenet of "never trust, always verify," utilizing granular micro-segmentation and continuous context-aware verification.
Defense in Depth: Implementing a multi-layered security strategy that deploys administrative (policies, training), technical (firewalls, encryption), and physical controls to protect resources.
Physical Security Access Controls: Managing access to physical spaces using structural designs such as security mantraps, turnstiles, anti-tailgating sensors, and restricted access paths within secure data centers.
Biometric Security Systems: Verifying identity using physical characteristics (fingerprints, retinas, iris patterns, facial recognition) and optimizing systems by balancing False Acceptance Rates (FAR) and False Rejection Rates (FRR).
Environmental & Infrastructure Controls: Protecting physical hardware facilities using environmental redundancies, including industrial HVAC systems, gaseous fire suppression systems (FM-200, Argonite), and seamless power transitions using Uninterruptible Power Supplies (UPS) and backup generators.
