Technologies Used

• tcpdump: For capturing network traffic.
• Wireshark: For analyzing captured packet data.
• Scapy: A Python library used for packet manipulation and analysis.
• Volatility: A tool for memory forensics.
• Python: For scripting and automation tasks.
• Ansible: For configuration management and enforcing security policies.

Setup Instructions

1. Capture Network Traffic: Execute the following command to capture network traffic:

   sudo tcpdump -i eth0 -nn -c 1000 -w pcap/capture_all.pcap
   

2. Analyze Network Traffic: Open the "capture_all.pcap" file in Wireshark. Apply filters to focus on HTTP and HTTPS traffic

3. Run Python Analysis Scripts: Execute the following command to analyze traffic data:

   python3 scripts/analyze_traffic.py
   

4. Conduct Memory Analysis: Use Volatility to analyze memory images:

   volatility -f mem_dump.raw --profile=WinXPSP2x86 pslist
   

5. Enforce Security Policies with Ansible: Run the following command to enforce security policies:

   ansible-playbook ansible/security_policies.yml
   
   

Results

• Packet Analysis: Successfully captured and analyzed network traffic, identifying suspicious connections for further investigation.
• Digital Forensic Analysis: Conducted thorough memory and log analysis to uncover potential security incidents.
• Security Policies: Developed compliance verification scripts and implemented network-wide policies using Ansible.

Conclusion

This project showcases a holistic approach to cybersecurity, demonstrating expertise in network monitoring, forensic analysis, and security policy implementation. It serves as a valuable asset for any cybersecurity professional's portfolio.
