May 2025 accomplished security automation and release hygiene across two Ostorlab repositories. Key features delivered: GraphQL Knowledge Bases Security Review Flag for New KBs in Ostorlab/KB, which automatically sets security_status to true for newly added GraphQL KBs to route them for security review. Commits: b4cabddff1a3ec0b58a2771a6f1b30533f2984d0. Release/maintenance in Ostorlab/oxo: Knowledge Base Submodule Synchronization and Version Metadata Update — updated the KB submodule reference to the latest commit and bumped oxo version from 1.6.2 to 1.6.3 for release metadata (no functional changes). Commits: ee487f7b4df97b7dad9793ce5e08cf0a1a484f18; 0f2cd1c1614a85e48044e7e664a7077f8ea56442. Major bugs fixed: none this month. Overall impact: improved security posture for new KBs, enhanced release readiness, and consistent cross-repo versioning. Technologies/skills demonstrated: GraphQL, security review automation, Git submodules, versioning, release management, cross-repo coordination.

April 2025 – Ostorlab/KB: GraphQL security hardening delivered via two major features. Key features delivered: (1) GraphQL Alias Limiting and Brute Force Protection — core hardening for alias limiting, query timeouts and brute-force protections; accompanying documentation and metadata updates (11 commits). (2) GraphQL API Security: Comprehensive Attack Vector Protections — protection against array-based batch queries, circular fragments/references, directive overloading, field duplication, POST-only methods, resource/complexity protections, plus tracing and secure debug mode practices (9 commits). Major bugs fixed: none logged as separate bugs; emphasis on security improvements rather than bug fixes. Overall impact: strengthens GraphQL security posture, reduces risk of resource exhaustion and unauthorized access, improves governance via secure KBs and documentation, enhancing customer trust and maintainability. Technologies/skills demonstrated: GraphQL security practices, security documentation, metadata/config management, secure KB development, tracing and debugging practices.

March 2025 — Ostorlab/oxo: strengthened vulnerability reporting and aligned release processes to boost triage speed and release reliability. Delivered the Vulnerability Reporting System enhancement by adding a RECORD_TYPE metadata type and renaming it to DNS_RECORD_TYPE across the protobuf and generated code, improving DNS-related record categorization and analytics. Finalized release readiness with a version bump to 1.5.3 in setup.cfg for the forthcoming release, reducing drift between development and deployment. These changes improve data clarity, enable faster triage, and streamline the next release workflow.
