INTERMEDIATE // MULTI LAYER STACKING
MODULE 05 // LAYER INTEGRATION

Threat Intelligence.

Enrich ABIS assessments with external threat intelligence for broader context.

EXTERNAL INTELLIGENCE INTEGRATION

Threat intelligence provides external context that ABIS cannot generate internally: IP reputation, known bad actors, active threat campaigns, and dark web credential exposure.

Integration patterns: pre-check (filter known bad before ABIS analysis), enrichment (add context to ABIS assessment), post-check (verify ABIS decisions against threat feeds).

Balance freshness vs cost. Real-time threat feed queries add latency and cost. Cache common lookups, but ensure cache TTL is short enough to catch rapidly-evolving threats.

IP REPUTATION

Check IP against known proxies, VPNs, datacenter IPs, and historically malicious addresses.

TTL: 1 HOUR

CREDENTIAL EXPOSURE

Check if user credentials appear in known breach databases. Trigger password reset if exposed.

TTL: 24 HOURS

THREAT CAMPAIGNS

Active threat campaign indicators. Block patterns associated with current attack waves.

TTL: 15 MIN

ACTOR DATABASE

Known bad actor fingerprints and patterns. Long-term blocklist for repeat offenders.

TTL: 7 DAYS
KNOWLEDGE CHECK // Q05
How should threat intelligence caching balance freshness vs cost?
