What Must Be In Place

Concrete structural preconditions — what must exist before this capability operates reliably.

Primary Structural Lever

Whether operational knowledge is systematically recorded

The structural lever that most constrains deployment of this capability.

Whether operational knowledge is systematically recorded

  • Systematic capture of all inbound email metadata, header fields, link destinations, and attachment hashes into structured security event logs with timestamps and sender reputation scores

How explicitly business rules and processes are documented

  • Documented classification policy defining phishing signal categories, severity tiers, and escalation thresholds as machine-readable rules with versioned approval records

How data is organized into queryable, relational formats

  • Taxonomy of threat indicator types (domain spoofing, credential harvesting, payload delivery, social engineering) with consistent labelling across security event records

Whether systems expose data through programmatic interfaces

  • Real-time query access to email gateway logs, Active Directory user-attribute data, and threat intelligence feeds via standardized API interfaces

How frequently and reliably information is kept current

  • Scheduled retraining cadence for phishing detection models with drift monitoring on false-positive and false-negative rates per threat category

Whether systems share data bidirectionally

  • Bidirectional data handoff between the email security platform and the SIEM, enabling correlated alert enrichment and incident ticket creation

Common Misdiagnosis

Security teams treat phishing detection as a vendor model problem and deploy off-the-shelf solutions without establishing structured capture of internal email telemetry, leaving the model blind to organisation-specific impersonation patterns and trusted-sender abuse.

Recommended Sequence

Start with capturing comprehensive email telemetry and historical phishing reports into structured logs before formalising classification policies, because policy thresholds must be calibrated against real signal distributions rather than abstract threat definitions.
