View User Access

Reviewing a user's recent service-level activity is very important before doing anything to it as it might delete an access from a principal (person or application), who is still using it.

Listing IAM Users

You can easily list the IAM users in your AWS account or in a specific IAM user group, and list all the user groups that a user is in, as described below.

To list all the users in the account

  1. AWS Management Console shows the users in your AWS account and you can choose Users from the navigation pane.
  2. AWS CLI: aws iam list-users.
  3. AWS API: ListUsers.

To list the users in a specific group

  1. You can select the User groups, their name, and the Users tab from the navigation pane of the AWS Management Console.
  2. AWS CLI: aws iam get-group.
  3. AWS API: GetGroup.

To list all the user groups that a user is in

  1. Select the Users, user name, and then, the Groups tab from the navigation pane of the AWS Management Console.
  2. AWS CLI: aws iam list-groups-for-user.
  3. AWS API: ListGroupsForUser.

Renaming an IAM User

As the console doesn't have an option for renaming or change a user's name or path, you must use the AWS CLI, Tools for Windows PowerShell, or AWS API and this change leads to the following things:
  1.  All the policies attached to the user stay with the user under the new name.
  2. The user stays in the same user groups under the new name.
  3.  The unique ID for the user remains the same. 
  4. All the resources or role policies that refers to the user as a principal will be automatically updated to use the new name or path. However, this doesn't happen when the user is referred as a resource, it should be done manually.

To rename a user

  1. AWS CLI: aws iam update-user.
  2. AWS API: UpdateUser.

  Azure Sentinel Workbooks Several ready for use templates are provided by the Azure Sentinel that can be used to create your own workbook and then modify them as needed for Contoso. Most of the data connectors it uses to ingest data come with their own workbooks, but better insight can be obtained by simply looking into the data that is being ingested by using tables and visualizations, including bar and pie charts. You can also make your own workbook easily by using this data from the beginning instead of using the predefined templates. Workbook Page You can easily access the workbook page from the Azure Sentinel from the navigation pane which consists of the: Workbook header- You can add a new workbook and review the saved workbooks as well as templates that are available on the workbook page.

The loaf balancer also offers an option of DirectServerReturn which if configured, can help in directing the traffic from the DBMS VM to the SAP application layer directly to the application layer without routing through the load balancer. But, if it isn't configured, then the return traffic to the SAP application layer is routed through the load balancer. You can also use Azure Load Balan
