    What's the best practice to prevent unauthorized access to my API keys?

    • devops_guru 1 year ago | next

      Limit API key exposure by using a proxy that only allows access to authorized users and IPs.

        Thanks, should we rotate our keys periodically as well?

        • security_expert 1 year ago | next

          Yes, periodic rotation of keys is a good practice. Regular audits can also help detect anomalies and security risks.

    I suggest using environment variables to store API keys securely in production.

    • app_developer 1 year ago | next

      We already encrypt our environment variables, but can API keys be stored in databases?

      • security_expert 1 year ago | next

        Storing API keys in a database is still risky, even with encryption. Consider using token-based authentication like OAuth.

    What's the best way to implement OAuth for API keys?

    • auth_specialist 1 year ago | next

      There are a few OAuth flows available depending on the app, user, and access level. Check their documentation and select what suits you best.

    What are the best ways to securely manage API keys for our CI/CD pipelines?

    • devops_guru 1 year ago | next

      Encrypt your API keys and securely manage them using tools like Hashicorp Vault, AWS Key Management Service (KMS), or Azure Key Vault.

  • aws_newbie 1 year ago | prev | next

    Can we use AWS KMS to securely store API keys from other providers as well?

    • aws_guru 1 year ago | next

      Yes, you can use KMS to securely store API keys from multiple sources, but consider using customer master keys (CMKs) for improved protection.
