Network Operations Center (NOC) – Open Source Implementation

📌 Project Overview

This project presents the design and implementation of a complete Network Operations Center (NOC) in a simulated enterprise environment.
It integrates monitoring, security, centralized logging, and incident management using open-source tools.

The infrastructure is deployed and tested using GNS3 and VMware Workstation, simulating a real-world enterprise network with VLAN segmentation and security controls.

🎯 Objectives

• Centralized monitoring of network devices and servers
• Real-time detection of failures and security incidents
• Centralized log collection and analysis
• Structured incident and asset management
• Simulation of an enterprise-grade NOC architecture

🏗️ Architecture Overview

The network is segmented into multiple VLANs:

VLAN	Name	Network	Purpose
10	Management	172.16.2.0/24	Admin access, monitoring tools
20	DMZ	172.16.1.0/24	NOC servers
30	LAN1	172.16.3.0/24	User clients
40	LAN2	172.16.4.0/24	Additional clients

Key components:

• pfSense: Firewall, VLAN routing, DHCP, NAT
• Zabbix: Performance & availability monitoring
• Wazuh: Security monitoring & centralized logging
• Snort: Intrusion Detection System (IDS)
• GLPI: IT asset management & ticketing

🧪 Testing & Validation

The infrastructure was validated through:

• VLAN connectivity tests
• DHCP assignment verification
• Zabbix performance alerts
• Snort intrusion detection (scan, ICMP flood)
• Centralized log validation in Wazuh
• Ticket creation and resolution in GLPI

Detailed test cases are documented in the tests/ directory.
