The onboarding process security review is the firewall against that risk. It is the moment where access, roles, and permissions are locked into place with precision.
Security reviews during onboarding stop dangerous defaults before they spread. They verify identity with strong authentication. They confirm least privilege access. They document every granted permission in a way that can be audited later without guesswork. This is where attack surfaces shrink and accountability grows.
A thorough onboarding security checklist starts with identity verification. Every new user, contractor, or service account must be tied to a verified source. Multi-factor authentication should be enforced from the first login, not as an afterthought. Role-based access control (RBAC) is next. Assign only the permissions needed to perform the work. No more, no less.
Review integration points. API keys, tokens, and service credentials often slip past initial audits. Each must be scoped tightly, rotated on schedule, and logged for monitoring. Check default configurations in connected systems. Disable unused modules. Remove generic accounts.
