PaaS Security Review: A Comprehensive Guide to Protecting Your Cloud Applications
Platform as a Service (PaaS) security is not theoretical—it is the thin line between a sealed system and a breached one. A PaaS security review cuts into the layers that sit between developer code and cloud infrastructure, auditing every point where trust meets exposure.
A strong review starts with identity and access management. All user and service accounts must follow least privilege. No shared credentials. No leftover roles with admin rights. Multi-factor authentication should be enforced everywhere. Logs must show when and why each access was granted or denied.
Next is network segmentation and data flow. A secure PaaS isolates workloads at the network level, enforces TLS 1.2+ for data in transit, and encrypts all persistent storage. API gateways should enforce authentication, rate limits, and request validation to stop abuse before it reaches core systems.
Configuration is often the weakest link. PaaS services can drift—default permissions reappear, open ports stay open, or unpatched dependencies linger. A proper review checks every setting against security benchmarks like CIS or NIST. Continuous configuration scanning catches drift before it becomes a vulnerability.
Application-level controls are critical. Runtime protection should detect anomalies and block malicious payloads. Build pipelines must scan for known vulnerabilities and enforce signed containers. Secrets must be managed in dedicated vaults, never in source control.
Monitoring closes the loop. Centralized logging and SIEM integration allow rapid detection of suspicious activity. Metrics and alerts must be actionable, not noise. Incident response plans should be ready, tested, and tied to both PaaS provider features and internal playbooks.
Security in PaaS is shared responsibility—but precision audits and continuous enforcement can tip the balance toward safety.
