Over five months, Cirtec delivered a robust IP and URL blocking infrastructure in the CIRTEC-QRO/Prueba_BloqueoIPs repository, focusing on scalable, policy-driven network security. Leveraging shell scripting and configuration management, Cirtec engineered batch updates to blocklists, expanded rule coverage, and optimized filtering performance. The work integrated threat intelligence and IP reputation management to proactively block malicious actors, including botnet and ransomware campaigns. Through disciplined version control and clear commit practices, Cirtec ensured maintainability and traceability. The resulting system improved access control, reduced exposure to emerging threats, and enabled rapid policy updates, reflecting a deep, iterative approach to security engineering.

Month: 2025-03 – CIRTEC-QRO/Prueba_BloqueoIPs Key features delivered: - Implemented blocklist enhancements for IPs and a malicious URL to block Mirai, Troldesh, and Trojan campaigns, consolidating related updates into a single, user-facing improvement. Major bugs fixed: - No major bugs reported in this period for this repository. Overall impact and accomplishments: - Strengthened defense against botnet and ransomware activities by expanding IP and URL blocklists, reducing exposure to known Mirai and Trojan campaigns. - Improved incident response readiness and user confidence through a consolidated, clearly communicated security improvement. - Maintained a clear audit trail with explicit commit messages, enabling traceability and compliance. Technologies/skills demonstrated: - Threat intelligence integration and security blocklists (IP reputation-based filtering, URL-based blocking). - Version control discipline and commit hygiene (clear, campaign-linked messages). - Security-focused deployment readiness and documentation.
