Hey folks! Just wrapped up a massive PCI-DSS audit for our cloud environments, and Orca Security was a huge part of our success. I wanted to share our exact configuration journey, focusing on the "how" rather than just the "what." Our goal was to get from initial setup to audit-ready reports with minimal noise and maximum compliance signal.
We started by defining our scope in Orca: all AWS accounts handling cardholder data. The key was using Orca's **Policy Sets** to laser-focus on the PCI-DSS v4.0 framework. Here's how we structured it:
1. **Created a dedicated "PCI-DSS Audit" policy set.**
2. **Enabled only the PCI-DSS v4.0 controls** within that set, temporarily disabling other alerts to reduce distraction.
3. **Fine-tuned alert severity** based on our risk assessment. For example, we set "Encryption of Cardholder Data at Rest" findings to `Critical`, while some "Audit Logging" alerts were set to `Medium`.
We also leveraged the **Exclusion Rules** heavily to cut down on false positives, but we did it in a traceable way. For instance, we had a legacy application with a specific, approved cryptographic module that Orca flagged. Instead of ignoring it globally, we scoped the exclusion tightly:
```yaml
# Example of a targeted exclusion rule we documented for auditors
rule_name: "PCI-Exclude-Legacy-App-Crypto"
resource_id: "i-1234567890abcdef0"
finding_id: "CIS-AWS-2.1.4"
justification: "Legacy application using FIPS 140-2 validated module, exception documented in RISK-12345"
```
The real win was automating the evidence collection. We used Orca's **API** to pull daily summary reports into our internal dashboards and fed critical findings directly into our GRC platform. This gave auditors a continuous compliance story, not just a point-in-time snapshot.
Biggest lessons learned:
* **Tagging is everything.** Orca's ability to filter by AWS tags (like `pci-scope=true`) saved us countless hours.
* **Start with the policy sets immediately.** Don't try to boil the ocean.
* **Document every exclusion.** Your auditor will ask.
The process wasn't without hiccups—some initial scans took longer than expected, and we had to adjust some resource permissions—but overall, it turned a traditionally painful manual process into a much more automated and reviewable one. Would love to hear if others have tackled similar audits and what your key configurations were!
