Firewall

  1. Repurposing 32-bit Laptop as Linux Firewall for Cybersecurity Lab - Implemented a host-based firewall using nftables and followed a zero-trust approach for default traffic.
  2. Bridging Lab to the Cloud with Site-to-Site VPN - Configured AWS Security Groups and applied strict nftables forwarding rules to restrict and secure traffic flowing through the encrypted tunnel.
  3. Developing Wazuh Decoders and Rules for Lab Firewall - Parsed raw nftables telemetry to engineer detection rules capable of identifying network reconnaissance, spoofed private IPs, and packet floods.
