项目说明

Cybersecurity Lab: A Hands-On SOC & Penetration Testing En

A fully isolated lab for simulating real-world cyber attacks (DDoS, MITM, Exploitation) and practising defensi operations with industry-standard tools

📜 Project O

This project addresses the critical gap between theoretical cybersecurity knowledge and practical skills. I designed, implemented, and documented a fully isolated cybersecurity laboratory using desktop . The lab provides a safe, legal, and controlled en to simulate real-world cyber threats and practice both offensive and defensi techniques, mirroring the workflows of a Security Operations Center (SOC).

The core of this project was to mo theory and build a platform for experiential learning, enabling hands-on practice in threat detection, incident response, and network defense.

🏗️ Lab Architecture

The lab is built on * Workstation Pro* using a *Host-Only network* (192.168.100.0/24) to ensure complete isolation from external networks. It consists of three specialized machines:

* *Attacker (Kali Linux):* A penetration testing platform equipped with tools for reconnaissance, exploitation, and attack simulation.
* *Target (Metasploitable 2):* An intentionally Ubuntu server, pro a realistic and safe target for practicing exploitation techniques.
* *Defender (Ubuntu Server 22.04):* A dedicated monitoring and defense platform, configured with tools for traffic analysis, intrusion detection, and firewall management.

🛠️ Tools & Technologies Used

| Category | Tools |
| :--- | :--- |
| ** | Workstation Pro |
| *Offensi* | Kali Linux, Nmap, Metasploit Framework, hping3, arpspoof (dsniff) |
| *Defensi* | Ubuntu Server, Wireshark, tcpdump, iptables, fail2ban, arpwatch |
| * Target* | Metasploitable 2 ( 2.3.4, etc.) |

🔬 Hands-On Exercises & Simulations

This lab was through several realistic cybersecurity scenarios that demonstrate its educational value:

1. Distributed Denial of Service (DDoS) Attack & Mitigation

* *Action:* Simulated a SYN flood attack from Kali against the Ubuntu ser hping3.
* *Detection:* Monitored the attack in real-time on the Ubuntu defender using *Wireshark* to analyze the traffic spike.
* *Mitigation:* Implemented and tested defensi* firewall rules on the Ubuntu server to rate-limit incoming traffic and block the attacker's IP, successfully mitigating the attack.

2. Exploitation & Patching (Full Lifecycle)

* *Recon:* Performed service and enumeration on Metasploitable using *Nmap* (-sV).
* *Exploit:* Identified the infamous * 2.3.4 backdoor (C)* and used the *Metasploit Framework* to exploit it, gaining a reverse shell on the target system.
* *Remediation:* "Patched" the by updating the service and hardening its configuration.
* *:* Re-scanned the target with Nmap and re-ran the exploit to confirm the was successfully mitigated.

3. Man-in-the-Middle (MITM) Attack with ARP Spoofing

* *Action:* Executed an ARP spoofing attack from Kali to intercept network traffic between the Metasploitable target and the Ubuntu defender.
* *Interception:* Enabled IP forwarding on Kali to become a transparent relay.
* *Analysis:* Used *tcpdump* on Kali to capture and analyze the li stream between the two machines, demonstrating how easily unencrypted communications can be intercepted.

🚀 Practical Use Cases

Beyond structured exercises, the lab is designed for practical application:

* *Rapid Deployment:* Pre-configured for a fully functional, multi-role lab en to be operational in minutes.
* *Safe Maintenance:* The Host-Only network ensures all malicious activity is contained. Temporary internet access can be enabled for *safe tool updates* (e.g., updating Kali's tool suite) without exposing the target.
* *Repeatable Learning:* * snapshots* are crucial, allowing the entire lab or indi machines to be re to a clean state in seconds. This enables endless, risk-free experimentation and consistent exercise repetition.

✅ & Key Achie

* *Pro:* Successfully configured a Host-Only network, confirming that communicate internally but had no access to the external internet.
* *Exercise Reproducibility:* the snapshot and recovery process, guaranteeing that the lab can be reset to a pristine state for consistent training.
* *Educational Value:* Demonstrated the lab's effecti by successfully executing three distinct attack/defense scenarios, pro a platform for de practical skills in threat response and network defense.
