Designing secure network architecture involves protecting data, devices, and users from unauthorized access, attacks, and disruptions. It starts with network segmentation, isolating critical assets and sensitive data into secure zones with controlled access. Firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) are deployed to monitor and manage traffic effectively.

Strong access controls, like multi-factor authentication (MFA) and role-based permissions, ensure only authorized users can access resources. Encryption safeguards data in transit and at rest.
