> TL;DR: Common blind spots around DSN-related flows: access, logs, test environments, and data reused beyond its intended scope.

In payroll software, DSN-related flows are not only a compliance concern. They are also an access, traceability, and data-separation concern.

The usual weak points

logs that expose too much operational detail;

test data too close to production reality;

overbroad support or admin access;

files reused outside their intended business scope.

What teams should revisit

The important question is simple: who can view, replay, export, or correct a DSN-related flow, and with what proof?

Key Takeaways

Identify and test your exposed attack surfaces before a third party does.

Client-side security controls never replace server-side validation.

Regular audits are more effective than one-time checks — vulnerabilities appear with every deployment.
