Log Management

  1. Repurposing 32-bit Laptop as Linux Firewall for Cybersecurity Lab - Separated logs into dedicated files, enabled log rotation to prevent massive disk usage over time, and set descriptive log prefixes.
  2. Bridging Lab to the Cloud with Site-to-Site VPN - Configured the lab firewall to forward telemetry logs securely to a centralized Wazuh SIEM hosted in AWS.
  3. Developing Wazuh Decoders and Rules for Lab Firewall - Built custom decoders using PCRE2 to extract structured fields from raw nftables and dnsmasq logs.
