Secure Redundant Network Design & Configuration

A Cisco-based redundant network architecture with layered security controls, built on CCNA Routing & Switching and Cyber Ops foundations.

Overview

Designed and configured a redundant enterprise network topology using Cisco equipment, applying CCNA Routing & Switching and Cyber Ops principles. The design incorporated layered security controls including segmentation, ASA-based firewalling, and failover paths to maintain availability under failure conditions.

Highlights

  • Designed redundant topologies for high availability under link or device failure.
  • Implemented Cisco ASA-based perimeter security and segmentation.
  • Applied CCNA Cyber Ops principles to harden the network design.
