Why SAP threat detection matters
SAP is the system of record for finance, supply chain, human resources, and treasury in many enterprises. A hostile actor inside SAP can manipulate vendor master, payment runs, payroll, and inventory in ways that are immediately financially material. Conventional security operations centers focus on the perimeter and the endpoint and rarely have detection content tuned for SAP application events. The result is a blind spot that an external auditor will note in the SoX ITGC walkthrough. The discipline of SAP threat detection rests on tailored signal sources, dedicated detection content, and a triage workflow that the SAP business owner can act on.

Signal sources for SAP detection
Five signal sources support SAP detection. The security audit log captures authentication, authorization, and transaction events. The change documents log captures master data and configuration changes. The transport log captures the path from development to production. The table logging captures changes to financially sensitive tables. The system log captures basis events. The customer position is to forward all five to the central SIEM with five minute latency or better. The reference is the discipline documented in the SAP audit trail analysis.

Detection content for SAP
The detection content covers eight scenarios that are specific to SAP. Privileged user logon at unusual hours. Mass change to vendor master bank account fields. Payment run executed outside the documented schedule. Authorization assignment to a sensitive role outside the workflow. RFC destination created with default credentials. Code execution through report submission with dynamic ABAP. Table change to a SoX in scope table outside the change window. Audit log deactivation. The eight scenarios cover the most common patterns of insider risk and external compromise that auditors expect detection coverage for.

Detection content tuned to SAP application events closes the most common audit finding against SoX ITGC monitoring. The tuning is the difference between a generic security operations center and one that protects the system of record.
Alert triage workflow
The triage workflow rests on a two tier model. The first tier is the security operations center analyst who validates the alert against the SAP context. The second tier is the SAP application security specialist who interprets the alert in the business context and assigns disposition. The disposition options are confirmed incident, suspicious requiring investigation, expected business activity, and false positive requiring tuning. Each disposition has a response time service level. The workflow is documented and the documentation supports the external audit walkthrough on detection effectiveness.

Monitoring posture that survives audit
The audit defensible monitoring posture rests on five controls. First, the five signal sources forwarded to central SIEM. Second, the eight detection scenarios with active rules. Third, the two tier triage workflow with response time service levels. Fourth, the quarterly review of detection tuning. Fifth, the annual tabletop exercise that tests the detection and response capability end to end. The five controls satisfy the SoX ITGC monitoring objective and the cyber insurance underwriter request for documentation.
