Top 5 Security Misconfigurations Causing Data Breaches | UpGuard

This report is a practical guide on security misconfigurations that can lead to data breaches: it catalogs common misconfiguration types (e.g., default settings, unnecessary features, insecure permissions, outdated software, insecure APIs), explains causes such as human error and cloud complexity, cites notable examples (Microsoft Power Apps leak, T‑Mobile API issues), and recommends mitigations including comprehensive security policies, MFA, IAM, patch management, SSDLC, zero-trust, monitoring and hardening—while highlighting how UpGuard’s tools can help detect and remediate these issues.
