# Security Enterprise Network Design

![Secure Company Network Packet Tracer](https://res.cloudinary.com/dtsm9eluo/image/upload/v1736501723/security_enterprise_network_project_hxc1dh.png)

---

## 🚀 Purpose

The primary objective of this project is to:

- Design a secure enterprise network architecture.

- Demonstrate communication between systems using routing and switching protocols.

- Implement and test security measures, including firewalls, VLANs, ACLs, and VPNs.

- Provide a scalable and redundant network for enterprise applications.

---

## 🖥️ Devices Used

- **Routers:** Cisco ISR Series (e.g., ISR 2911) for routing and inter-network communication.

- **Switches:** Cisco Catalyst Series (e.g., Catalyst 2960) for VLAN and inter-VLAN routing.

- **Firewalls:** Simulated firewall devices for network perimeter security.

- **Servers:**

  - Authentication Server (e.g., AAA Server).

  - DNS Server.

  - Application Servers (Web and Database).

- **End Devices:** PCs, laptops, and wireless devices connected through VLANs.

---

## 📡 System Communication

### Communication Protocols:

- **Routing Protocols:** OSPF/EIGRP for efficient network routing.

- **Switching:** VLANs (802.1Q) for logical traffic segmentation.

- **Security Measures:**

  - ACLs for traffic filtering.

  - Firewalls for access control.

  - VPNs for secure remote communication.

---

## 🔧 Configuration

### Key Configurations:

1. **Routers:**

   - OSPF/EIGRP configuration for dynamic routing.

   - NAT for external access.

   - VPN tunnels for secure remote access.

2. **Switches:**

   - VLAN configurations for segmentation.

   - Trunking for inter-VLAN communication.

3. **Firewalls:**

   - Rule-based access control for inbound/outbound traffic.

   - Stateful packet inspection.

4. **Servers:**

   - DNS configuration for name resolution.

   - Authentication services (e.g., RADIUS).

## 🛠️ Setup Instructions

1. **Install Cisco Packet Tracer:**

   - Download from [Cisco NetAcad](https://www.netacad.com/).

2. **Open Project File:**

   - Clone this repository and load the `.pkt` file in Cisco Packet Tracer.

3. **Inspect and Configure:**

   - Open the devices in Packet Tracer to review the topology.

   - Apply any necessary configurations (VLANs, routing, firewalls, etc.).

4. **Simulate:**

   - Use simulation mode to test connectivity and verify security policies.

5. **Document Results:**

   - Record test results and analyze the network's performance.

---

## 🌀 Workflow

1. **Planning:**

   - Define the network's objectives, such as scalability, redundancy, and security.

   - Design the topology and device roles.

2. **Implementation:**

   - Configure VLANs, routing, firewalls, and servers.

   - Set up remote access through VPNs.

3. **Testing:**

   - Simulate traffic and validate network configurations.

   - Verify ACLs, routing protocols, and connectivity.

4. **Optimization:**

   - Troubleshoot any issues and fine-tune configurations.

5. **Documentation:**

   - Maintain detailed records of configurations, addressing schemes, and test results.
