Topic #: 1

[All AWS Certified Security - Specialty Questions]

A company is running an application on Amazon EC2 instances in an Auto Scaling group. The application stores logs locally. A security engineer noticed that logs were lost after a scale-in event. The security engineer needs to recommend a solution to ensure the durability and availability of log data. All logs must be kept for a minimum of 1 year for auditing purposes.
What should the security engineer recommend?

A. Within the Auto Scaling lifecycle, add a hook to create an attach an Amazon Elastic Block Store (Amazon EBS) log volume each time an EC2 instance is created. When the instance is terminated, the EBS volume can be reattached to another instance for log review.
B. Create an Amazon Elastic File System (Amazon EFS) file system and add a command in the user data section of the Auto Scaling launch template to mount the EFS file system during EC2 instance creation. Configure a process on the instance to copy the logs once a day from an instance Amazon Elastic Block Store (Amazon EBS) volume to a directory in the EFS file system.
C. Build the Amazon CloudWatch agent into the AMI used in the Auto Scaling group. Configure the CloudWatch agent to send the logs to Amazon CloudWatch Logs for review.
D. Within the Auto Scaling lifecycle, add a lifecycle hook at the terminating state transition and alert the engineering team by using a lifecycle notification to Amazon Simple Notification Service (Amazon SNS). Configure the hook to remain in the Terminating:Wait state for 1 hour to allow manual review of the security logs prior to instance termination.

None of these answers have a cloudwatch logs retention period in their answer. So here it is, just incase you care. "To get started, see Sending CloudTrail Events to CloudWatch Logs in the AWS CloudTrail User Guide . Log Retention – By default, logs are kept indefinitely and never expire. You can adjust the retention policy for each log group, keeping the indefinite retention, or choosing a retention period between 10 years and one day." https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html So, yea -C-

Selected Answer: C

While reading the question, you might think of lifecycle hook, but then when you read the option you find out that there's a better way of doing it..CW Logs agent baked into AMI used in ASG launch template. C is the correct answer.

The security engineer should recommend option C. They can build the Amazon CloudWatch agent into the AMI used in the Auto Scaling group and configure the CloudWatch agent to send the logs to Amazon CloudWatch Logs for review. This will ensure the durability and availability of log data and all logs can be kept for a minimum of 1 year for auditing purposes.

Answer B: Reason: When you first create a security group, it has no inbound rules. Therefore, no inbound traffic originating from another host to your instance is allowed until you add inbound rules to the security group.

i think your answer is regarding a different question, here answer B is regarding EFS and copying the logs once a day, once a day is bad since you wont get the logs of the crash since you wont get to the 'once a day' part of the day, answer is C
