Implementing Next-Generation Firewalls (NGFW) and Intrusion Prevention Systems (IPS) at the boundary between the internal network and the internet. 4. Modern Evolution: SD-WAN and Cloud

Not all data is equal. A good design prioritizes time-sensitive traffic—like Voice over IP (VoIP) or video conferencing—over standard web browsing to ensure clear communication. 3. Security by Design network design

We are moving away from purely hardware-centric designs toward . SD-WAN allows companies to manage their network via software, automatically routing traffic over the most efficient path (e.g., using a cheap internet connection for basic apps and a private line for critical data). Additionally, "Hybrid" designs now integrate local office hardware seamlessly with cloud providers like AWS or Azure, treating the cloud as an extension of the local data centre. Conclusion SD-WAN allows companies to manage their network via

Using VLANs to isolate sensitive departments (like Finance or R&D) from the rest of the network. This prevents "lateral movement" if one device is compromised. 2. Core Principles: Performance and Reliability

The "driveways." This is where end-user devices (PCs, printers, Wi-Fi APs) connect. It focuses on port security and providing power (PoE) to devices. 2. Core Principles: Performance and Reliability
