ISSA The Global Voice of Information Security Network Security Architecture

Secure networks are crucial for IT systems and their proper operations as most applications work in the networking environment and closely depend on its performance, reliability, and security. Improper network design can be very expensive for a company (i.e., loss of business continuity, security incidents, costs of network rebuilding, etc.). Essential to network design is the security architecture that describes the network segmentation (i.e., security zones) and security layers (i.e., access control, intrusion prevention, content inspection, etc.). An appropriate design of the architecture provides many advantages (e.g., isolation of low trust systems, limitation of a security breach’s scope, costs savings).
