Hybrid Cloud Network Design (On-premises)

This network design is the On-Premises section of my hybrid AWS cloud architecture. This design is influenced by cybersecurity principles such as high redundancy, defense in depth, network segmentation, and zero trust. It also contains technical networking elements such as VLANs, subnetting, and extended firewall controls


VLANs

A Virtual Local Area Network (VLAN) divides a physical network into separate logical networks, grouping devices by function or security needs. VLANs enhance security by isolating traffic, preventing unauthorized access, limiting malware spread, and reducing network congestion. With access control lists and firewalls, VLANs ensure only authorized data flows between segments, safeguarding sensitive information.

Subnetting

Subnetting splits a large network into smaller subnetworks using IP address segmentation, improving organization and security. It isolates traffic between subnets, limiting unauthorized access and malware spread by confining threats to a single subnet

Extended Firewall

An extended firewall enhances network security beyond basic filtering by using stateful inspection, deep packet inspection, and intrusion detection to monitor and control traffic. It secures networks by blocking sophisticated threats like malware and unauthorized access, enforcing application-layer policies, and using threat intelligence to prevent attacks and protect data.

Network Segmentation

This security concept splits a network into smaller segments using tools like VLANs, subnets, and firewalls to control traffic and boost security. It limits unauthorized access, limiting threats like malware to specific segments, and prevents attackers from moving freely across the network.
