Defense in Depth Strategy

Layered Security

Multiple security controls at each layer ensure that if one control fails, others provide protection.

Holistic Approach

Security spans from physical infrastructure to application code, covering all attack vectors across the OSI model.

Continuous Monitoring

SIEM, IDS/IPS, and logging provide visibility and threat detection across all layers.

Key Security Principles

Zero Trust Architecture

Never trust, always verify. Authenticate, authorize, and encrypt every request.

Least Privilege

Grant only the minimal access required to reduce attack surface.

Security by Design

Integrate security into design and development pipelines, not as an afterthought.

Incident Response

Prepare detection, response, and recovery playbooks for every layer.
