Enterprise Network Security Infrastructure

A simulated secure banking network implemented using Cisco Packet Tracer.
This project demonstrates practical enterprise network security concepts including VLAN segmentation, ACL enforcement, SSH secure administration, Syslog monitoring, and attack simulation.

---

Project Overview

The network was designed to simulate a secure enterprise banking infrastructure with multiple departments separated using VLANs and protected through access control mechanisms.

The project includes:

• VLAN Segmentation
• Router-on-a-Stick Configuration
• Access Control Lists (ACLs)
• SSH Secure Remote Administration
• Syslog Monitoring
• Internal Web Server Access Control
• Security Validation & Attack Simulation
