Nov 1, 2024

November 2024 (Azure/Azure-Sentinel) delivered measurable business value through packaging automation, ingestion efficiency, and governance-aligned repo modernization. Key packaging and deployment work established end-to-end ZIP tooling for funcapp and templates, enabling reliable builds and simplified rollouts. Ingest cadence optimization reduced unnecessary processing by persisting and reusing last ingest/analysis times. UTC timezone alignment for BEH parameters ensured consistent time handling across environments. Added scheduling to run connectors twice daily, improving data freshness. Executed a major migration and version upgrade to align with Azure-Sentinel, updating deployment artifacts and schema references (2.x→4.x) and migrating sources from DavidItkin to Azure/Azure-Sentinel, reducing fragmentation and risk. These efforts demonstrated proficiency in build tooling, data engineering, time-zone normalization, scheduling, and cross-repo governance.

2024-10 Monthly Summary for Azure/Azure-Sentinel: Delivered key security analytics features, enhanced data quality, and established centralized ingestion for BloodHound Enterprise. Implemented new BloodHound Enterprise analysis workbooks and ensured their discoverability, extended the event logging schema for richer auditing, and launched a BloodHound Enterprise Azure Sentinel data connector with Function App-based ingestion. Note: initial connector currently duplicates log records due to missing persisted timestamp; mitigation planned in upcoming sprint.
