As networks grow, misconfigurations and unsecured devices pose increased risk. Learners will analyze network architecture, identify exposures, and offer detailed recommendations to harden systems.

• Conduct a basic audit of a network (real or simulated) to identify weaknesses in configuration, topology, and access controls. Propose changes to improve security and minimize attack surfaces.

Tasks and Activities:

• Analyze provided network diagrams or configuration snapshots
• Document existing network components and access points
• Identify vulnerable services, open ports, or weak firewall rules
• Propose revisions to firewall settings, VLAN structure, or segmentation
• Recommend secure configuration practices for routers, switches, or servers
• Summarize findings in an audit report with before-and-after visuals

Deliverables:

• Network Audit Report
• Annotated Network Diagram (before and proposed changes)
• Firewall Rule Review Summary
• Recommendations Deck with Prioritized Actions
