A company has an application that uses an Amazon RDS PostgreSQL database. The company is developing an application feature that will store sensitive information for an individual in the database.
During a security review of the environment, the company discovers that the RDS DB instance is not encrypting data at rest. The company needs a solution that will provide encryption at rest for all the existing data and for any new data that is entered for an individual.
Which combination of options can the company use to meet these requirements? (Select TWO.)
A security engineer is designing an IAM policy for a script that will use the AWS CLI. The script currently assumes an IAM role that is attached to three AWS managed IAM policies: AmazonEC2FullAccess, AmazonDynamoDBFullAccess, and Ama-zonVPCFullAccess.
The security engineer needs to construct a least privilege IAM policy that will replace the AWS managed IAM policies that are attached to this role.
Which solution will meet these requirements in the MOST operationally efficient way?
A company needs to use HTTPS when connecting to its web applications to meet compliance requirements. These web applications run in Amazon VPC on Amazon EC2 instances behind an Application Load Balancer (ALB). A security engineer wants to ensure that the load balancer win only accept connections over port 443. even if the ALB is mistakenly configured with an HTTP listener
Which configuration steps should the security engineer take to accomplish this task?
A company is developing an ecommerce application. The application uses Amazon EC2 instances and an Amazon RDS MySQL database. For compliance reasons, data must be secured in transit and at rest. The company needs a solution that minimizes operational overhead and minimizes cost.
Which solution meets these requirements?
A company uses Amazon Elastic Container Service (Amazon ECS) containers that have the Fargate launch type. The containers run web and mobile applications that are written in Java and Node.js. To meet network segmentation requirements, each of the company's business units deploys applications in its own dedicated AWS account.
Each business unit stores container images in an Amazon Elastic Container Registry (Amazon ECR) private registry in its own account.
A security engineer must recommend a solution to scan ECS containers and ECR registries for vulnerabilities in operating systems and programming language libraries.
The company's audit team must be able to identify potential vulnerabilities that exist in any of the accounts where applications are deployed.
Which solution will meet these requirements?
A company is developing a highly resilient application to be hosted on multiple Amazon EC2 instances . The application will store highly sensitive user data in Amazon RDS tables
The application must
• Include migration to a different IAM Region in the application disaster recovery plan.
• Provide a full audit trail of encryption key administration events
• Allow only company administrators to administer keys.
• Protect data at rest using application layer encryption
A Security Engineer is evaluating options for encryption key management
Why should the Security Engineer choose IAM CloudHSM over IAM KMS for encryption key management in this situation?
A company has a new partnership with a vendor. The vendor will process data from the company's customers. The company will upload data files as objects into an Amazon S3 bucket. The vendor will download the objects to perform data processing. The objects will contain sensi-tive data.
A security engineer must implement a solution that prevents objects from resid-ing in the S3 bucket for longer than 72 hours.
Which solution will meet these requirements?
A security engineer is troubleshooting an AWS Lambda function that is named MyLambdaFunction. The function is encountering an error when the function attempts to read the objects in an Amazon S3 bucket that is named DOC-EXAMPLE-BUCKET. The S3 bucket has the following bucket policy:
Which change should the security engineer make to the policy to ensure that the Lambda function can read the bucket objects?
A security engineer needs to create an Amazon S3 bucket policy to grant least privilege read access to IAM user accounts that are named User=1, User2. and User3. These IAM user accounts are members of the AuthorizedPeople IAM group.The security engineer drafts the following S3 bucket policy:
When the security engineer tries to add the policy to the S3 bucket, the following error message appears: "Missing required field Principal." The security engineer is adding a Principal element to the policy. The addition must provide read access to only User1. User2, and User3.Which solution meets these requirements?
A)
B)
C)
D)
A company must retain backup copies of Amazon RDS DB instances and Amazon Elastic Block Store (Amazon EBS) volumes. The company must retain the backup copies in data centers that are several hundred miles apart.
Which solution will meet these requirements with the LEAST operational overhead?
A company recently had a security audit in which the auditors identified multiple potential threats. These potential threats can cause usage pattern changes such as DNS access peak, abnormal instance traffic, abnormal network interface traffic, and unusual Amazon S3 API calls. The threats can come from different sources and can occur at any time. The company needs to implement a solution to continuously monitor its system and identify all these incoming threats in near-real time.
Which solution will meet these requirements?
An IAM user receives an Access Denied message when the user attempts to access objects in an Amazon S3 bucket. The user and the S3 bucket are in the same AWS account. The S3 bucket is configured to use server-side encryption with AWS KMS keys (SSE-KMS) to encrypt all of its objects at rest by using a customer managed key from the same AWS account. The S3 bucket has no bucket policy defined. The IAM user has been granted permissions through an IAM policy that allows the kms:Decrypt permission to the customer managed key. The IAM policy also allows the s3:List* and s3:Get* permissions for the S3 bucket and its objects.
Which of the following is a possible reason that the IAM user cannot access the objects in the S3 bucket?
A company is evaluating the use of AWS Systems Manager Session Manager to gam access to the company's Amazon EC2 instances. However, until the company implements the change, the company must protect the key file for the EC2 instances from read and write operations by any other users.
When a security administrator tries to connect to a critical EC2 Linux instance during an emergency, the security administrator receives the following error. "Error Unprotected private key file - Permissions for' ssh/my_private_key pern' are too open".
Which command should the security administrator use to modify the private key Me permissions to resolve this error?
A security engineer is designing security controls for a fleet of Amazon EC2 instances that run sensitive workloads in a VPC. The security engineer needs to implement a solution to detect and mitigate software vulnerabilities on the EC2 instances.
Which solution will meet this requirement?
A company runs workloads in the us-east-1 Region. The company has never deployed resources to other AWS Regions and does not have any multi-Region resources.
The company needs to replicate its workloads and infrastructure to the us-west-1 Region.
A security engineer must implement a solution that uses AWS Secrets Manager to store secrets in both Regions. The solution must use AWS Key Management Service(AWS KMS) to encrypt the secrets. The solution must minimize latency and must be able to work if only one Region is available.
The security engineer uses Secrets Manager to create the secrets in us-east-1.
What should the security engineer do next to meet the requirements?
A company uses AWS Organizations to manage an organization that consists of three workload OUs Producbon Development and Testing. The company uses AWS CloudFormation templates to define and deploy workload infrastructure in AWS accounts that are associated with the OUs Different SCPs are attached to each workload OU.
The company successfully deployed a CloudFormation stack update to workloads in the Development OU and the Testing OU. When the company uses the same CloudFormation template to deploy the stack update in an account in the Production OU the update fails The error message reports insufficient 1AM permissions.
What is the FIRST step that a security engineer should take to troubleshoot this issue?
A company needs to store multiple years of financial records. The company wants to use Amazon S3 to store copies of these documents. The company must implement a solution to prevent the documents from being edited, replaced, or deleted for 7 years after the documents are stored in Amazon S3. The solution must also encrypt the documents at rest.
A security engineer creates a new S3 bucket to store the documents.
What should the security engineer do next to meet these requirements?
A developer has created an AWS Lambda function in a company's development account. The Lambda function requires the use of an AWS Key Management Service (AWS KMS) customer managed key that exists in a security account that the company's security team controls. The developer obtains the ARN of the KMS key from a previous Lambda function in the development account. The previous Lambda function had been working properly with the KMS key.
When the developer uses the ARN and tests the new Lambda function an error message states that access is denied to the KMS key in the security account. The developer tests the previous Lambda function that uses the same KMS key and discovers that the previous Lambda function still can encrypt data as expected.
A security engineer must resolve the problem so that the new Lambda function in the development account can use the KMS key from the security account.
Which combination of steps should the security engineer take to meet these requirements? (Select TWO.)
A company is using IAM Secrets Manager to store secrets for its production Amazon RDS database. The Security Officer has asked that secrets be rotated every 3 months. Which solution would allow the company to securely rotate the secrets? (Select TWO.)
A company has two IAM accounts within IAM Organizations. In Account-1. Amazon EC2 Auto Scaling is launched using a service-linked role. In Account-2. Amazon EBS volumes are encrypted with an IAM KMS key A Security Engineer needs to ensure that the service-linked role can launch instances with these encrypted volumes
Which combination of steps should the Security Engineer take in both accounts? (Select TWO.)
