Who Accessed What and When in PaaS: Achieving Full-Stack Visibility

The logs told a story no one wanted to read. A service account ran at midnight, pulling data it shouldn’t have touched. Questions followed fast: who accessed what, and when?

Platform as a Service (PaaS) environments make it easy to deploy fast and scale without friction. But that simplicity hides complexity. Access can come from apps, users, scripts, or integrations. If you don’t track every permission and event, you lose visibility. And without visibility, you lose control.

The core challenge is knowing, in real time, the full path of every access event. This means recording the identity, the resource touched, the exact timestamp, and the originating IP or service. PaaS logs, audit trails, and authorization services must work together. Without that integration, data is fragmented across dashboards, making incident response slow and incomplete.

To answer "who accessed what and when" in PaaS, enforce strong identity management. Use single sign-on, multi-factor authentication, and granular role-based access control. Permanent credentials in code or config files should be eliminated. Rotate keys and enforce expiry policies. Each change in permissions should be logged and reviewed.

Monitor continuously. Stream audit logs from the PaaS provider into centralized logging systems. Correlate them with application logs and API gateway logs. Dashboards should display real-time state and allow historical searches. Alerts must trigger when access patterns diverge from the norm.

Compliance frameworks like SOC 2, ISO 27001, and HIPAA demand proof of control over "who accessed what and when." Meeting these requires precise logging, immutable storage, and fast retrieval during audits. Cloud-native tooling can help, but only if configured to capture the right fields with consistent timestamp formats.

When breaches happen, the speed of your forensic analysis depends entirely on the accuracy of these records. Missing fields or delayed log ingestion will leave gaps. And those gaps are where attackers hide.
