Secure Network Infrastructure with Cisco Firepower and VPN Integration

"Secure Network Infrastructure with Cisco Firepower and VPN Integration."

This project is a comprehensive network security simulation in Cisco Packet Tracer, integrating advanced firewalls, authentication, VPNs, and access controls to create a secure and efficient enterprise network.

I gained hands-on experience in defensive cybersecurity and network security, focusing on:

Basic Network & End-Device Configuration: Setting up routers, switches, and end devices while testing connectivity and reachability.

VLANs, VLAN Security & Inter-VLAN Routing: Configuring VLANs to segment network traffic, securing VLANs against attacks, and enabling communication between VLANs using inter-VLAN routing and DHCP.

Access Control Lists (ACLs): Enforcing traffic filtering policies for better security.

Layer 2 Security: Protecting networks from attacks like MAC spoofing and VLAN hopping.

802.1X Authentication: Enhancing port security with identity-based network access control.

Zone-Based Policy Firewalls (ZPF): Implementing robust firewall rules to safeguard networks.

Intrusion Prevention Systems (IPS): Detecting and mitigating cyber threats in real time.

Established a Site-to-Site IPsec VPN for secure inter-site communication.

Firewall Policy Configurations: Structuring rules to regulate network traffic securely.
