SECURITY CORRELATION

What Is Security Event Correlation?

Security correlation is the process of considering relationships between multiple events or findings instead of evaluating each observation independently.

An isolated event may tell only part of the story

A single failed login may be normal. Repeated authentication failures combined with another unusual event can provide a different level of context.

Correlation connects evidence

Security correlation can consider relationships such as:

  • Repeated observations over time
  • Multiple findings associated with the same asset
  • Related authentication activity
  • Different sources describing the same security condition
  • Historical patterns affecting current risk interpretation

Correlation is not the same as certainty

A correlated pattern does not automatically prove malicious activity. It creates additional context that can help a human reviewer decide what deserves attention.

Why this matters for smaller organisations

Teams with limited security resources need to avoid spending unnecessary time reviewing disconnected low-value observations.

Better context can help prioritise where human attention should be directed.

AssayMark security intelligence

AssayMark is being developed around contextual analysis, historical security memory and correlation so that related evidence can support more explainable security decisions.
