Network Security Project

where I designed and implemented a robust security architecture using Cisco ASA and VPN technologies. This project enhances perimeter defense, intrusion prevention, secure remote access, and access control to create a strong and secure network environment.

️ Key Implementations:

Cisco ASA Firewall & Firepower NGFW for perimeter security

Intrusion Prevention System (IPS) to detect & block malicious traffic

Zone-Based Firewall (ZBF) for advanced traffic filtering

Access Control Lists (ACLs) to restrict unauthorized access

IPsec VPNs for encrypted remote communication

Network Segmentation with OSPF authentication & dynamic routing

Layer 2 Security Enhancements: VLAN hopping & MAC spoofing protection

AAA Server (RADIUS & TACACS+) for centralized authentication & access control

Spanning Tree Protocol (STP) for network redundancy

DHCP Snooping & Dynamic ARP Inspection (DAI) to prevent network attacks

Syslog Server Configuration for centralized logging & monitoring

Network Time Protocol (NTP) Configuration for time synchronization across devices
