A corporation utilizes distinct accounts for varying stages of their software lifecycle to improve security and segregation of environments. Their policy mandates that a specialized team must be equipped to quickly respond and exercise full permissions in any of these accounts during critical incidents. Which strategy should be implemented to confer the specialized team the necessary elevated access in line with best practices for security?
Create user accounts with high-level permissions within each environment for the response team, distributing credentials as needed.
Implement organization-wide service control policies to grant the response team emergency access to all environments.
Establish roles for cross-environment access that the specialized response team can assume when elevated permissions are necessary.
Use a centralized identity management service for streamlined team authentication across all environments, avoiding specific roles for emergency situations.
