The Security team believes that a former employee may have gained unauthorized access to AWS resources sometime in the past 3 months by using an identified access key.
What approach would enable the Security team to find out what the former employee may have done within AWS?
A
A company is storing data in Amazon S3 Glacier. The security engineer implemented a new vault lock policy for 10TB of data and called initiate-vault-lock operation 12 hours ago. The audit team identified a typo in the policy that is allowing unintended access to the vault.
What is the MOST cost-effective way to correct this?
A
Initiate the lock by attaching a vault lock policy to your vault, which sets the lock to an in-progress state and returns a lock ID. While in the in-progress state, you have 24 hours to validate your vault lock policy before the lock ID expires.
Use the lock ID to complete the lock process. If the vault lock policy doesn't work as expected, you can abort the lock and restart from the beginning. For information on how to use the S3 Glacier API to lock a vault, see Locking a Vault by Using the Amazon S3 Glacier API.

A threat assessment has identified a risk whereby an internal employee could exfiltrate sensitive data from production host running inside AWS (Account 1). The threat was documented as follows:
Threat description: A malicious actor could upload sensitive data from Server X by configuring credentials for an AWS account (Account 2) they control and uploading data to an Amazon S3 bucket within their control.
Server X has outbound internet access configured via a proxy server. Legitimate access to S3 is required so that the application can upload encrypted files to an
S3 bucket. Server X is currently using an IAM instance role. The proxy server is not able to inspect any of the server communication due to TLS encryption.
Which of the following options will mitigate the threat? (Choose two.)
AC
A company will store sensitive documents in three Amazon S3 buckets based on a data classification scheme of `Sensitive,` `Confidential,` and `Restricted.` The security solution must meet all of the following requirements:

✑ AWS KMS must automatically rotate encryption keys annually.
Which of the following meets these requirements?
A
