A company Is planning to use Amazon Elastic File System (Amazon EFS) with its on-premises servers. The company has an existing IAM Direct Connect connection established between its on-premises data center and an IAM Region Security policy states that the company's on-premises firewall should only have specific IP addresses added to the allow list and not a CIDR range. The company also wants to restrict access so that only certain data center-based servers have access to Amazon EFS How should a security engineer implement this solution''
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?
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 has two AWS accounts: Account A and Account B. Account A has an IAM role that IAM users in Account B assume when they need to upload sensitive documents to Amazon S3 buckets in Account A. A new requirement mandates that users can assume the role only if they are authenticated with multi-factor authentication (MFA). A security engineer must recommend a solution that meets this requirement with minimum risk and effort. Which solution should the security engineer recommend?
A security engineer must use AWS Key Management Service (AWS KMS) to design a key management solution for a set of Amazon Elastic Block Store (Amazon EBS) volumes that contain sensitive data. The solution needs to ensure that the key material automatically expires in 90 days. Which solution meets these criteria?
An international company has established a new business entity in South Kore a. The company also has established a new AWS account to contain the workload for the South Korean region. The company has set up the workload in the new account in the ap-northeast-2 Region. The workload consists of three Auto Scaling groups of Amazon EC2 instances. All workloads that operate in this Region must keep system logs and application logs for 7 years. A security engineer must implement a solution to ensure that no logging data is lost for each instance during scaling activities. The solution also must keep the logs for only the required period of 7 years. Which combination of steps should the security engineer take to meet these requirements? (Choose three.)
A company is operating a website using Amazon CloudFornt. CloudFront servers some content from Amazon S3 and other from web servers running EC2 instances behind an Application. Load Balancer (ALB). Amazon DynamoDB is used as the data store. The company already uses IAM Certificate Manager (ACM) to store a public TLS certificate that can optionally secure connections between the website users and CloudFront. The company has a new requirement to enforce end-to-end encryption in transit. Which combination of steps should the company take to meet this requirement? (Select THREE.)
A Development team has built an experimental environment to test a simple stale web application It has built an isolated VPC with a private and a public subnet. The public subnet holds only an Application Load Balancer a NAT gateway, and an internet gateway. The private subnet holds ail of the Amazon EC2 instances There are 3 different types of servers Each server type has its own Security Group that limits access lo only required connectivity. The Security Groups nave both inbound and outbound rules applied Each subnet has both inbound and outbound network ACls applied to limit access to only required connectivity Which of the following should the team check if a server cannot establish an outbound connection to the internet? (Select THREE.)
A company is deploying an Amazon EC2-based application. The application will include a custom health-checking component that produces health status data in JSON format.

A company has secured the AWS account root user for its AWS account by following AWS best practices. The company also has enabled AWS CloudTrail, which is sending its logs to Amazon S3. A security engineer wants to receive notification in near-real time if a user uses the AWS account root user credentials to sign in to the AWS Management Console.

Which solutions will provide this notification? (Select TWO.)

A.
Use AWS Trusted Advisor and its security evaluations for the root account. Configure an Amazon EventBridge event rule that is invoked by the Trusted Advisor API. Configure the rule to target an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe any required endpoints to the SNS topic so that these endpoints can receive notification.

Suggested answer: C, E

Explanation:

To receive near-real-time notifications of AWS account root user sign-ins, the most effective solutions involve the use of AWS CloudTrail logs, Amazon CloudWatch Logs, and Amazon EventBridge.

Solution C involves configuring AWS CloudTrail to send logs to Amazon CloudWatch Logs and then setting up a CloudWatch Logs metric filter to detect successful root account logins. When such logins are detected, a CloudWatch alarm can be configured to trigger and notify an Amazon Simple Notification Service (Amazon SNS) topic, which in turn can send notifications to the required endpoints. This solution provides an efficient way to monitor and alert on root account usage without requiring custom parsing or handling of log data.

Solution E uses Amazon EventBridge to monitor for specific AWS API calls, such as SignIn events that indicate a successful root account login. By configuring an EventBridge rule to trigger on these events, notifications can be sent directly to an SNS topic, which then distributes the alerts to the necessary endpoints. This approach leverages native AWS event patterns and provides a streamlined mechanism for detecting and alerting on root account activity.

Both solutions offer automation, scalability, and the ability to integrate with other AWS services, ensuring that stakeholders are promptly alerted to critical security events involving the root user.
