Cyber Threat Intelligence in a Cloud-Centric World
Cyber threats move quickly, and cloud environments expand your attack surface. In a cloud-centric world, threat intelligence must combine external feeds with your own cloud telemetry to stay useful. Teams often receive data from many tools, but without a clear plan it becomes noise. A simple approach helps: define what to watch, how to normalize it, and who will use the results.
Key data sources include both outside signals and inside observations:
- Cloud provider logs: AWS CloudTrail, Azure Activity Logs, Google Cloud Audit Logs
- Cloud-native security tools: CSPM, CWPP, CNAPP
- Identity and access analytics: unusual login patterns, key creation, privilege changes
- Network and application telemetry: VPC flow logs, DNS logs, API gateways
- Threat feeds and vulnerability alerts: vendor advisories, open source feeds
- Internal incident history: past breaches, near misses, lessons learned
Clouds also present challenges: enormous data volume, noisy signals, and silos across security, DevOps, and SRE teams. Misconfigurations and excessive permissions are common weak points. Attacker techniques in cloud differ from on-prem, such as API abuse, credential compromise, and rapid movement across services.
To make threat intelligence work in practice, align with a formal framework and a repeatable process:
- Map cloud events to a framework like MITRE ATT&CK for cloud
- Build an ingestion pipeline with normalization, enrichment, and scoring
- Share insights with the right teams: SOC, DevSecOps, and incident response
- Automate enrichment and response where possible, using SIEM or SOAR playbooks
Practical steps you can take today:
- Start with a small, curated set of feeds plus your own telemetry
- Normalize data to a common schema (for example, JSON with timestamps, sources, and indicators)
- Tag and rate signals, linking IOCs to cloud events
- Create rules that automatically enrich cloud signals with context (which service, region, user)
- Integrate with your security platform and incident response playbooks
- Review and update signals after incidents; test for false positives
Key Takeaways
- Cloud threat intel requires combining external feeds with cloud telemetry.
- Focus on data quality, normalization, and automation.
- Align with MITRE ATT&CK for cloud and integrate with SOC/DevSecOps.
