AWS Certified Security - Specialty Questions and Answers

Question 21

A company uses AWS Organizations to manage a small number of AWS accounts. However, the company plans to add 1 000 more accounts soon. The company allows only a centralized security team to create IAM roles for all AWS accounts and teams. Application teams submit requests for IAM roles to the security team. The security team has a backlog of IAM role requests and cannot review and provision the IAM roles quickly.

The security team must create a process that will allow application teams to provision their own IAM roles. The process must also limit the scope of IAM roles and prevent privilege escalation.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Create an IAM group for each application team. Associate policies with each IAM group. Provision IAM users for each application team member. Add the new IAM users to the appropriate IAM group by using role-based access control (RBAC).

Delegate application team leads to provision IAM rotes for each team. Conduct a quarterly review of the IAM rotes the team leads have provisioned. Ensure that the application team leads have the appropriate training to review IAM roles.

Put each AWS account in its own OU. Add an SCP to each OU to grant access to only the AWS services that the teams plan to use. Include conditions tn the AWS account of each team.

Create an SCP and a permissions boundary for IAM roles. Add the SCP to the root OU so that only roles that have the permissions boundary attached can create any new IAM roles.

Answer:

Explanation:

To create a process that will allow application teams to provision their own IAM roles, while limiting the scope of IAM roles and preventing privilege escalation, the following steps are required:

Create a service control policy (SCP) that defines the maximum permissions that can be granted to any IAM role in the organization. An SCP is a type of policy that you can use with AWS Organizations to manage permissions for all accounts in your organization. SCPs restrict permissions for entities in member accounts, including each AWS account root user, IAM users, and roles. For more information, see Service control policies overview.
Create a permissions boundary for IAM roles that matches the SCP. A permissions boundary is an advanced feature for using a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM entity. A permissions boundary allows an entity to perform only the actions that are allowed by both its identity-based policies and its permissions boundaries. For more information, see Permissions boundaries for IAM entities.
Add the SCP to the root organizational unit (OU) so that it applies to all accounts in the organization. This will ensure that no IAM role can exceed the permissions defined by the SCP, regardless of how it is created or modified.
Instruct the application teams to attach the permissions boundary to any IAM role they create. This will prevent them from creating IAM roles that can escalate their own privileges or access resources they are not authorized to access.

This solution will meet the requirements with the least operational overhead, as it leverages AWS Organizations and IAM features to delegate and limit IAM role creation without requiring manual reviews or approvals.

The other options are incorrect because they either do not allow application teams to provision their own IAM roles (A), do not limit the scope of IAM roles or prevent privilege escalation (B), or do not take advantage of managed services whenever possible ©.

Question 22

A company is implementing new compliance requirements to meet customer needs. According to the new requirements the company must not use any Amazon RDS DB instances or DB clusters that lack encryption of the underlying storage. The company needs a solution that will generate an email alert when an unencrypted DB instance or DB cluster is created. The solution also must terminate the unencrypted DB instance or DB cluster.

Which solution will meet these requirements in the MOST operationally efficient manner?

Options:

Create an AWS Config managed rule to detect unencrypted ROS storage. Configure an automatic remediation action to publish messages to an Amazon Simple Notification Service (Amazon SNS) topic that includes an AWS Lambda function and an email delivery target as subscribers. Configure the Lambda function to delete the unencrypted resource.

Create an AWS Config managed rule to detect unencrypted RDS storage. Configure a manual remediation action to invoke an AWS Lambda function. Configure the Lambda function to publish messages to an Amazon Simple Notification Service (Amazon SNS) topic and to delete the unencrypted resource.

Create an Amazon EventBridge rule that evaluates RDS event patterns and is initiated by the creation of DB instances or DB clusters Configure the rule to publish messages to an Amazon Simple Notification Service (Amazon SNS) topic that includes an AWS Lambda function and an email delivery target as subscribers. Configure the Lambda function to delete the unencrypted resource.

Question 23

A company in France uses Amazon Cognito with the Cognito Hosted Ul as an identity broker for sign-in and sign-up processes. The company is marketing an application and expects that all the application's users will come from France.

When the company launches the application the company's security team observes fraudulent sign-ups for the application. Most of the fraudulent registrations are from users outside of France.

The security team needs a solution to perform custom validation at sign-up Based on the results of the validation the solution must accept or deny the registration request.

Which combination of steps will meet these requirements? (Select TWO.)

Options:

Create a pre sign-up AWS Lambda trigger. Associate the Amazon Cognito function with the Amazon Cognito user pool.

Use a geographic match rule statement to configure an AWS WAF web ACL. Associate the web ACL with the Amazon Cognito user pool.

Configure an app client for the application's Amazon Cognito user pool. Use the app client ID to validate the requests in the hosted Ul.

Update the application's Amazon Cognito user pool to configure a geographic restriction setting.

Use Amazon Cognito to configure a social identity provider (IdP) to validate the requests on the hosted Ul.

Question 24

An Application team has requested a new IAM KMS master key for use with Amazon S3, but the organizational security policy requires separate master keys for different IAM services to limit blast radius.

How can an IAM KMS customer master key (CMK) be constrained to work with only Amazon S3?

Options:

Configure the CMK key policy to allow only the Amazon S3 service to use the kms Encrypt action

Configure the CMK key policy to allow IAM KMS actions only when the kms ViaService condition matches the Amazon S3 service name.

Configure the IAM user's policy lo allow KMS to pass a rote lo Amazon S3

Configure the IAM user's policy to allow only Amazon S3 operations when they are combined with the CMK
