Core Frameworks & Modern Security Architectures

Core Frameworks & Modern Security Architectures

To counter evolving vectors, enterprise security strategies must shift from reactive controls to proactive, continuous architectures.

Zero Trust Architecture (ZTA)

The fundamental principle of Zero Trust is “Never Trust, Always Verify.” It assumes that threats exist both outside and inside the network boundary.

1. Explicit Verification: Authenticate and authorize continuously based on all available data points (user identity, location, device health, service, or workload).

2. Least Privilege Access: Limit user access with Just-In-Time (JIT) and Just-Enough-Access (JEA) policies.

3. Assume Breach: Minimize blast radius by segmenting access, encrypting end-to-end, and utilizing analytics to gain visibility.

Cloud Security Posture Management (CSPM) & SASE

With workloads moving to multi-cloud environments (AWS, Azure, Google Cloud), securing infrastructure requires dedicated platforms:

• CSPM (Cloud Security Posture Management): Automates the identification and remediation of risks across cloud infrastructures, ensuring compliance with security standards.

• SASE (Secure Access Service Edge): Combines network security functions (like SWG, CASB, and FWaaS) with WAN capabilities to support secure remote access.
