Access Control Implementation
Over-permissioned accounts are the most common finding in security audits. We implement least-privilege access control across your entire stack — IAM policies, role-based access, just-in-time elevation, and automated access reviews — so every identity has exactly the permissions it needs and nothing more.
Need this done for your project?
We implement, you ship. Async, documented, done in days.
IAM Policy Architecture
We redesign IAM from scratch: no inline policies, no wildcard permissions, no shared credentials. Permission boundaries set maximum possible privileges per role. Service control policies (SCPs) enforce organization-wide guardrails. IAM roles use assume-role patterns with session tags for fine-grained, attribute-based access control. Every policy is documented with its business justification. The result is an IAM architecture that an auditor can review and understand in 30 minutes.
Just-in-Time Access
Standing administrative access to production is eliminated. Engineers request temporary elevated access through a JIT system (Teleport, AWS IAM Identity Center, or custom automation). Requests specify the resource, permission level, duration, and business justification. Approvals are automated for pre-defined scenarios and manual for exceptional cases. Sessions are logged, time-limited (maximum 4 hours), and automatically revoked. Zero standing privileges means a compromised credential has zero production access.
Service Account Management
Service accounts (application credentials, CI/CD tokens, API keys) are the most dangerous credentials because they never expire and rarely get rotated. We implement: dedicated IAM roles per service with minimal permissions, short-lived credentials via IRSA (IAM Roles for Service Accounts) in Kubernetes, automated rotation for long-lived credentials, and monitoring for service account usage anomalies. No service account has admin access. Period.
Automated Access Reviews
Quarterly access reviews are automated: IAM Access Analyzer identifies unused permissions, a script generates an access report showing every identity and its permissions, managers review and approve via a simple web interface, and unapproved access is revoked automatically. The review process produces an audit trail with timestamps and approvals. Access creep — the gradual accumulation of permissions over time — is identified and remediated systematically.
