Summary
Security engineer Day shares lessons from security work: ship a useful first-pass IOC-based cloud detection during a monitored crypto-mining campaign, refine it later, model cloud threats at scale, prioritize intelligence by organizational impact, and document repeatab
Key points
- While monitoring a cloud crypto-mining campaign, Day says his team used an IOC-heavy detection to gain visibility quickly, with plans to refine it after the immediate pressure passed.
- For cloud detection work, he recommends threat modeling services and shared attack surfaces first, then translating the findings into focused detection questions and rules.
- He advises filtering threat intelligence according to its impact on the organization and making those decisions repeatable, rather than following headline severity alone.
- He describes documenting defensive systems, organizing knowledge-sharing sessions, and building a centralized knowledge base to reduce reliance on tribal knowledge.
- His framework emphasizes understanding organizational context, choosing scalable priorities, executing and iterating, and using incidents and data to guide future work.
- He argues that security and engineering speed can work together when teams provide structured, usable paths and improve them over time.
