Amazon Web Services AWS Certified Security - Specialty SCS-C02 Exam Dumps: Updated Questions & Answers (October 2025)

Enable Amazon Macie:

Amazon Macie automatically scans S3 buckets for sensitive data, such as PII, and uses managed data identifiers for efficient classification.

Configure Data Identifiers:

Use managed data identifiers for pre-configured sensitive data patterns like credit card numbers, personal information, etc.

Set Up Notifications:

Create an Amazon EventBridge rule to trigger on Macie findings.

Configure the rule to send notifications to the existing SNS topic.

Advantages:

Automated: Minimal manual intervention needed.

Efficient: Leverages Macie’s built-in capabilities to reduce implementation effort.

the reason why there were no alerts on the sudo commands. Sudo commands are commands that allow a user to execute commands as another user, usually the superuser or root. CloudWatch Logs agent is a software agent that can send log data from an EC2 instance to CloudWatch Logs, a service that monitors and stores log data. The CloudWatch Logs agent needs an IAM instance profile, which is a container for an IAM role that allows applications running on an EC2 instance to make API requests to AWS services. If the IAM instance profile on the EC2 instance was not properly configured to allow the CloudWatch Logs agent to push the logs to CloudWatch, then there would be no alerts on the sudo commands. The other options are either irrelevant or invalid for explaining why there were no alerts on the sudo commands.

To redesign the edge security to help mitigate the DDoS attack risk in the future, the engineer could do the following:

Move the static content to Amazon S3, and front this with an Amazon CloudFront distribution. This allows the engineer to use a global content delivery network that can cache static content at edge locations and reduce the load on the origin servers.

Use AWS WAF security rules to inspect the inbound traffic. This allows the engineer to use web application firewall rules that can filter malicious requests based on IP addresses, headers, body, or URI strings, and block them before they reach the web servers.

Use Amazon Route 53 to distribute traffic. This allows the engineer to use a scalable and highly available DNS service that can route traffic based on different policies, such as latency, geolocation, or health checks.

To troubleshoot the issue of an EC2 instance failing to start and transitioning to a terminated state when it has an EBS volume encrypted with an AWS KMS customer managed key, a security engineer should take the following steps:

C. Verify that the KMS key that is associated with the EBS volume is in the Enabled state. If the key is not enabled, it will not function properly and could cause the EC2 instance to fail.

D. Verify that the EC2 role that is associated with the instance profile has the correct IAM instance policy to launch an EC2 instance with the EBS volume. If the instance does not have the necessary permissions, it may not be able to mount the volume and could cause the instance to fail.

Therefore, options C and D are the correct answers.

The error message indicates that the private key file permissions are too open, meaning that other users can read or write to the file. This is a security risk, as the private key should be accessible only by the owner of the file. To fix this error, the security administrator should use the chmod command to change the permissions of the private key file to 0400, which means that only the owner can read the file and no one else can read or write to it.

The chmod command takes a numeric argument that represents the permissions for the owner, group, and others in octal notation. Each digit corresponds to a set of permissions: read (4), write (2), and execute (1). The digits are added together to get the final permissions for each category. For example, 0400 means that the owner has read permission (4) and no other permissions (0), and the group and others have no permissions at all (0).

The other options are incorrect because they either do not change the permissions at all (D), or they give too much or too little permissions to the owner, group, or others (A, C).

The below diagram from an IAM blog shows how security groups can be monitored

Option A is invalid because you need to use Cloudwatch Events to check for chan,

Option B is invalid because you need to use Cloudwatch Events to check for chang

Option C is invalid because IAM inspector is not used to monitor the activity on Security Groups

The correct answer is: Use Cloudwatch events to be triggered for any changes to the Security Groups. Configure the Lambda function for email notification as well.

the most secure way to meet the requirements. TLS is a protocol that provides encryption and authentication for data in transit. ALB is a service that distributes incoming traffic across multiple EC2 instances. HIDS is a system that monitors and detects malicious activity on a host. ECDHE is a type of cipher suite that supports perfect forward secrecy, which is a property that ensures that past and current TLS traffic stays secure even if the certificate private key is leaked. By creating a listener on the ALB that does not enable PFS cipher suites, and using encrypted connections to the servers using ECDHE cipher suites, you can ensure that the HIDS agents can capture the traffic of the EC2 instance without compromising the privacy of the users. The other options are either less secure or less compatible with the third-party solution.

The correct answer is C. Use AWS Resource Access Manager (AWS RAM) to share Account-A’s VPC subnets with the remaining member accounts. Configure the member accounts to use the shared subnets to launch workloads.

This answer is correct because AWS RAM is a service that helps you securely share your AWS resources across AWS accounts, within your organization or organizational units (OUs), and with IAM roles and users for supported resource types1.One of the supported resource types is VPC subnets2, which means you can share the subnets in Account-A’s VPC with the other member accounts using AWS RAM. This way, you can meet the requirements of using a centrally managed VPC, avoiding duplicate VPCs in each account, and launching workloads in shared subnets.You can also control the access to the shared subnets by using IAM policies and resource-based policies3, which can prevent one account from modifying another account’s resources.

The other options are incorrect because:

A.Using aCloudFormation template in the member accounts to launch workloads and using the Fn::ImportValue function to obtain the subnet ID values is not a solution, because Fn::ImportValue can only import values that have been exported by another stack within the same region4. This means that you cannot use Fn::ImportValue to reference the subnet IDs that are exported by Account-A’s CloudFormation template, unless all the member accounts are in the same region as Account-A. This option also does not avoid creating duplicate VPCs in each account, which is one of the requirements.

B. Using a transit gateway in the VPC within Account-A and configuring the member accounts to use the transit gateway to access the subnets in Account-A to launch workloads is not a solution, because a transit gateway does not allow you to launch workloads in another account’s subnets.A transit gateway is a network transit hub that enables you to route traffic between your VPCs and on-premises networks5, but it does not enable you to share subnets across accounts.

D. Creating a peering connection between Account-A and the remaining member accounts and configuring the member accounts to use the subnets in Account-A through the VPC peering connection to launch workloads is not a solution, because a VPC peering connection does not allow you to launch workloads in another account’s subnets.A VPC peering connection is a networking connection betweentwo VPCs that enables you to route traffic between them privately6, but it does not enable you to share subnets across accounts.

Set Up AWS Client VPN:

Deploy a Client VPN endpoint in the region where the VPCs are located.

Authorization Rule:

Configure the VPN endpoint with authorization rules to allow access only to the specific VPC subnets that the consultant needs.

VPC Peering Consideration:

Ensure routing between the peered VPCs is correctly configured to allow traffic from the Client VPN endpoint.

Advantages:

Secure Access: Provides encrypted access to the VPCs.

Granular Control: Restricts access to only required resources.
