Building a Secure Architecture

A modern cybersecurity implementation follows a defense‑in‑depth strategy:

1. Perimeter Controls – firewalls, IDS/IPS.
2. Network Segmentation – VLANs, micro‑segmentation.
3. Identity & Access Management (IAM) – MFA, least‑privilege policies.
4. Endpoint Protection – EDR solutions.
5. Data Protection – encryption at rest & in transit, DLP.
6. Security Operations Center (SOC) – continuous monitoring, SIEM.
7. Incident Response Plan – defined playbooks and regular tabletop exercises.
