Project-Lockdown

Network security project demonstrating offensive techniques and defensive solutions using Kali Linux, Ubuntu, and Metasploitable2.

Project Lockdown: Enterprise Network & Systems Hardening

Overview

Project Lockdown is a comprehensive cybersecurity simulation focused on assessing, exploiting, and securing an enterprise infrastructure. The project covers end-to-end security operations—from initial reconnaissance and vulnerability exploitation to implementing robust defense controls and auditing mechanisms.

Key Highlights & Artifacts

• Full Documentation: Detailed report available in Project-Lockdown-Report.pdf.
• Execution Proof & Screenshots: Visual proof of offensive tactics and defensive hardening configurations can be found in the Screenshots/ folder.

Technical Scope

Offensive Phases (Red Teaming)

• Reconnaissance & Enumeration: Target discovery and service identification.
• Exploitation & Initial Access: Weaponization and vulnerable service exploitation.
• Traffic Interception & Exfiltration: ARP spoofing, packet inspection, and data exfiltration techniques.
• Lateral Movement & Ransomware Simulation: Lateral movement across subnets and payload execution impact.

Defensive Hardening (Blue Teaming)

• Network Defense: iptables rules and static ARP table enforcement to prevent MITM attacks.
• Data & Storage Security: AES-256 file encryption using GPG and SHA-256 checksum integrity verification.
• Logging & Monitoring: System audit logging via journald and persistent event tracking.
