I collected and enriched DNS logs from multiple servers with GeoIP and WHOIS data, implementing blacklist and IoC-based detection systems to identify blacklisted domains, IoCs, and attack signatures. I also developed an AI model to classify domains as benign or malicious and designed an interactive dashboard with detailed visualizations to monitor data and detection metrics. To strengthen the platform's functionality, I implemented a user alerting mechanism to promptly notify users of potential intrusions.
