Granting Temporary Access in Google Cloud
Blog post from P0 Security
Granting temporary access in Google Cloud can enhance identity security by utilizing Conditional IAM to attach expiration times to role bindings, thereby minimizing the risks associated with excess permissions and simplifying access management. This approach ensures engineers only access production environments when necessary, preventing potential unintentional impacts and aiding compliance by avoiding permanent grants to sensitive resources. The process involves using the Google Cloud Console or CLI to specify expiration conditions for role binding, which remains intact but inactive post-expiration. However, limitations exist, such as the inability to use basic roles with IAM conditions and the clutter caused by expired bindings. To address these challenges, solutions like P0 Security automate the granting and revocation of temporary access, bypassing some of Google Cloud's limitations and maintaining a clean IAM policy.
