SCS-C02 Exam Dumps : AWS Certified Security - Specialty

You can establish a private connection between your VPC and Secrets Manager by creating an interface VPC endpoint. Interface endpoints are powered by AWS PrivateLink, a technology that enables you to privately access Secrets Manager APIs without an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection.

The correct answer is D. Configure a Secrets Manager interface VPC endpoint. Include the Lambda function’s private subnet during the configuration process.

A Secrets Manager interface VPC endpoint is a private connection between the VPC and Secrets Manager that does not require an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection1. By configuring a Secrets Manager interface VPC endpoint, the security engineer can enable the custom Lambda function to communicate with Secrets Manager without sending or receiving network traffic through the internet.The security engineer must include the Lambda function’s private subnet during the configuration process to allow the function to use the endpoint2.

The other options are incorrect for the following reasons:

A.An egress-only internet gateway is a VPC component that allows outbound communication over IPv6 from instances in the VPC to the internet, and prevents the internet from initiating an IPv6 connection with the instances3. However, this option does not meet the requirement that the VPC must not send or receive network traffic through the internet.Moreover, an egress-only internet gateway is for use with IPv6 traffic only, and Secrets Manager does not support IPv6 addresses2.

B.A NAT gateway is a VPC component that enables instances in a private subnet to connect to the internet or other AWS services, but prevents the internet from initiating connections with those instances4. However, this option does not meet therequirement that the VPC must not send or receive network traffic through the internet.Additionally, a NAT gateway requires an elasticIP address, which is a public IPv4 address4.

C.A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses5. However, this option does not work because Secrets Manager does not have a default VPC that can be peered with.Furthermore, a VPC peering connection does not provide a private connection to Secrets Manager APIs without an internetgateway or other devices2.

Comprehensive and Detailed Explanation From Exact Extract:

The GuardDuty finding “IAMUser/InstanceCredentialExfiltration” indicates that temporary credentials from the instance metadata service have been stolen and used from an unusual location. The immediate priority is to revoke all existing IAM sessions for that instance profile to block the compromised credentials.

This is considered a critical containment action. IAM allows active session revocation, which invalidates credentials associated with a compromised instance profile.

This is explicitly covered under the Incident Response domain in the AWS Security Specialty study material, which emphasizes session revocation and credential rotation in response to exfiltration events.

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.
