Steps to setup AWS CT:
Setting up a Control Tower on a new account is relatively simpler when compared to setting it up on an existing account. Once Control Tower is set up, the landing zone should have the following.
- 2 Organizational Units
- 3 accounts, a master account and isolated accounts for log archive and security audit
- 20 preventive guardrails to enforce policies
- 2 detective guardrails to detect config violations
The next step is to create a new Organizational unit and then create a new account using the account factory and map it to the OU that was created. Once this is done, you can start setting up your resources and any non-compliance starts reflecting in the Noncompliant resources’ dashboard. In addition to this, any deviation to the standard AWS best practices would be reflected in the dashboard.
With many of the organizations opting for and using AWS cloud services, AWS Control Tower with the centralized management service offers the simplest way to set up and govern multiple AWS accounts securely through beneficial features and established best practices.
