PCI-DSS 4.0 Compliance Automation — A Complete Guide

Walk through all 12 PCI-DSS 4.0 requirements and how DKTrace maps security events to each control — automatically collecting, timestamping, and signing evidence with chain-of-custody for QSA auditors.

The PCI-DSS 4.0 Challenge

PCI-DSS 4.0 introduced 64 new requirements compared to v3.2.1. Many SOC teams are still manually collecting evidence for audits — a process that takes months and introduces human error. DKTrace automates this end-to-end.

How DKTrace Maps to PCI-DSS 4.0

The Evidence Chain

Every piece of evidence DKTrace collects is:

1SHA-256 hashed at collection time
2HSM-signed with the artifact-store's key
3Written to an immutable custody_log table (append-only, no DELETE privilege)
4NTP-timestamped in UTC with sub-millisecond precision
5Exportable as a court-admissible PDF via the report-engine

Your QSA gets a signed, timestamped evidence package — not a spreadsheet.

Requirement 10 — Audit Log Deep Dive

Requirement 10 is the most log-intensive. DKTrace satisfies it as follows:

10.2.1.1 User authentication events: all 4624/4625/4648 Windows events, all SSH auth, all API auth
10.2.1.2 Actions with root/admin: all sudo events, all privileged API calls
10.2.1.3 Access to audit logs: all queries to the event-store table are themselves logged
10.3.2 Audit log protection: ClickHouse event-store is read-only to all service accounts except event-ingestion. No DELETE or UPDATE allowed.
10.5.1 Retain logs for 12 months: configurable retention, default 12 months hot + cold tiering to S3/MinIO

One-Click Audit Report

DKTrace's report-engine generates a complete PCI-DSS 4.0 evidence package on demand:

Per-requirement evidence summary
Event counts with date ranges
Exception log (gaps in coverage, suppressed events)
Digital signature and chain-of-custody certificate
Export formats: PDF, JSON, XML (for QSA tools)

Typical generation time for a 12-month evidence package: 47 seconds.
