Data Silo at Transmission
What This Pattern Is
When data is created successfully in a source system (badge reader, CCTV, HR system) but is not transmitted to the systems that depend on it (SIEM, access control, incident response), the data becomes isolated. No downstream system can act on, correlate, or learn from it.
How to Recognize It
Data exists in source system but is never queried elsewhere
No API or integration connects source system to downstream consumers
Manual export/import required (if it happens at all)
Different teams operate systems without awareness of each other
Incident response team discovers data only after incident
What Happens as a Result
Intelligence available in source system is invisible to analysts
Correlation impossible across physical and cyber data
Compliance audits cannot see complete picture
Incident response is slower and less complete
Patterns across systems never emerge
Why It Happens
Systems purchased at different times without integration plan
No unified data governance requiring cross-system transmission
Cost of integration deferred or not budgeted
Legacy systems lack modern APIs
Organizational silos prevent cross-team collaboration
When patterns are documented, they become frameworks.
