A company runs an application on a fleet of Amazon EC2 instances. The application is accessible to users around the world. The company associates an AWS WAF web ACL with an Application Load Balancer (ALB) that routes traffic to the EC2 instances.
A security engineer is investigating a sudden increase in traffic to the application. The security engineer discovers a significant amount of potentially malicious requests coming from hundreds of IP addresses in two countries. The security engineer wants to quickly limit the potentially malicious requests but does not want to prevent legitimate users from accessing the application.
Which solution will meet these requirements?
A company hosts a web application on an Apache web server. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The company configured the EC2 instances to send the Apache web server logs to an Amazon CloudWatch Logs group that the company has configured to expire after 1 year.
Recently, the company discovered in the Apache web server logs that a specific IP address is sending suspicious requests to the web application. A security engineer wants to analyze the past week of Apache web server logs to determine how many requests that the IP address sent and the corresponding URLs that the IP address requested.
What should the security engineer do to meet these requirements with the LEAST effort?
A company runs a public web application on Amazon EKS behind Amazon CloudFront and an Application Load Balancer (ALB). A security engineer must send a notification to an existing Amazon SNS topic when the application receives 10,000 requests from the same end-user IP address within any 5-minute period.
Which solution will meet these requirements?
A company has a PHP-based web application that uses Amazon S3 as an object store for user files. The S3 bucket is configured for server-side encryption with Amazon S3 managed keys (SSE-S3). New requirements mandate full control of encryption keys.
Which combination of steps must a security engineer take to meet these requirements? (Select THRE
E.
)A security engineer needs to prepare a company ' s Amazon EC2 instances for quarantine during a security incident. The AWS Systems Manager Agent (SSM Agent) has been deployed to all EC2 instances. The security engineer has developed a script to install and update forensics tools on the EC2 instances.
Which solution will quarantine EC2 instances during a security incident?
A security engineer is troubleshooting an AWS Lambda function that is namedMyLambdaFunction. The function is encountering an error when the function attempts to read the objects in an Amazon S3 bucket that is namedDOC-EXAMPLE-BUCKET. The S3 bucket has the following bucket policy:
{
" Effect " : " Allow " ,
" Principal " : { " Service " : " lambda.amazonaws.com " },
" Action " : " s3:GetObject " ,
" Resource " : " arn:aws:s3:::DOC-EXAMPLE-BUCKET " ,
" Condition " : {
" ArnLike " : {
" aws:SourceArn " : " arn:aws:lambda:::function:MyLambdaFunction "
}
}
}
Which change should the security engineer make to the policy to ensure that the Lambda function can read the bucket objects?
A company begins to use AWS WAF after experiencing an increase in traffic to the company’s public web applications. A security engineer needs to determine if the increase in traffic is because of application-layer attacks. The security engineer needs a solution to analyze AWS WAF traffic.
Which solution will meet this requirement?
A company manages multiple AWS accounts through an organization in AWS Organizations. The company enables all features in the organization.
A security team must implement a solution to centrally manage VPC security groups across the accounts. The company uses an existing reference security group with the required configuration. The solution must detect if security group rules have been modified to deviate from the reference security group. The solution must automatically restore any noncompliant security groups to match the reference security group.
The security team needs to select a solution that does not require custom development or scripting.
Which solution will meet these requirements?
A company uses AWS Organizations to manage its AWS accounts in a single organization. The company applies the FullAWSAccess SCP to every OU. However, now the company must explicitly deny specific services. The company needs a solution that restricts any users in the organization from using the explicitly denied services.
Additionally, the solution must enforce all Amazon S3 buckets across the organization to have a minimum TLS version of 1.2. The company requires a central solution that applies to all existing accounts and any new accounts that the company creates in the future.
