01
The Challenge
API keys and database credentials were hardcoded in application config files and shared informally between team members, with no rotation policy and no way to know who had access to what.
02
The Approach
1
Deployed HashiCorp Vault for centralized secrets storage, replacing hardcoded credentials across application configs.
2
Migrated services to fetch secrets dynamically at runtime instead of from static config files committed to version control.
3
Implemented role-based, least-privilege IAM policies so team members and services only have access to what their role requires.
4
Set up automatic credential rotation for database and third-party API keys.
03
The Outcome
Every credential is now centrally managed, rotated automatically, and access-logged, closing off a major source of unmanaged risk and giving the client an audit trail they didn't previously have.
