Create an AWS WAF Web ACL:

Use AWS WAF to create a web ACL for the CloudFront distribution.

Add Managed Rules for Bot Protection:

Include theAWSManagedRulesACFPRuleSetto protect against automated bots and account fraud.

Add a Rate-Based Rule:

Implement a rate limit rule to restrict the number of requests to/store/registrationduring promotions.

Example rule: Deny requests exceeding 100 per minute.

Associate the Web ACL with CloudFront:

Attach the web ACL to the CloudFront distribution to enforce the rules globally at edge locations.

Advantages:

Prevents Fraudulent Activity: Detects and mitigates bot activity.

Scalable: Operates at the CloudFront level, ensuring global protection.

"Before you assign your permission set with IAM policies, you must prepare your member account. The name of an IAM policy in your member account must be a case-sensitive match to name of the policy in your management account. IAM Identity Center fails to assign the permission set if the policy doesn't exist in your member account."

Comprehensive and Detailed Explanation From Exact Extract:

To prevent developers from configuring unauthenticated Lambda function URLs, the most effective approach is to use Service Control Policies (SCPs) at the organizational level. By explicitly denying actions such as lambda:CreateFunctionUrlConfig and lambda:UpdateFunctionUrlConfig when the lambda:FunctionUrlAuthType is set to NONE, the organization ensures that only authenticated function URLs are deployed in production.

This method imposes no additional workload on developers and leverages AWS Organizations' SCPs to enforce centralized security policy — a recommended practice in the Identity and Access Management domain.

because these are the steps that can ensure that the service-linked role can launch instances with encrypted volumes. A service-linked role is a type of IAM role that is linked to an AWS service and allows the service to perform actions on your behalf. A KMS grant is a mechanism that allows you to delegate permissions to use a customer master key (CMK) to a principal such as a service-linked role.A KMS grant specifies the actions that the principal can perform, such as encrypting and decrypting data. By creating a KMS grant for the service-linked role with the specified actions, you can allow the service-linked role to use the CMK in Account-2 to launch instances with encrypted volumes. By attaching an IAM policy to the role attached to the EC2 instances with KMS actions and then allowing Account-1 in the KMS key policy, you can also enable cross-account access to the CMK and allow the EC2 instances to use the encrypted volumes. The other options are either incorrect or unnecessary for meeting the requirement.

A. New patch baseline with 0-day approval ensures that critical security patches are available immediately for deployment without delay, which is crucial in response to imminent threats.

B. Patch Now operation in Patch Manager allows for immediate patch deployment across all instances, and storing logs in Amazon S3 provides centralized evidence and audit trails for compliance and verification.

Together, these actions support rapid response, immediate patch deployment, and auditability, aligning with Infrastructure Security and Incident Response best practices.

In an AWS environment where a VPC has no internet access and requires communication with AWS services such as Secrets Manager, the most secure method is to use an interface VPC endpoint (AWS PrivateLink). This allows private connectivity to services like Secrets Manager, enabling AWS Lambda functions and other resources within the VPC to access Secrets Manager without requiring an internet gateway, NAT gateway, or VPN connection. Interface VPC endpoints are powered by AWS PrivateLink, a technology that enables private connectivity between AWS services using Elastic Network Interfaces (ENI) with private IPs in your VPCs. This option is more secure than creating a NAT gateway because it doesn't expose the resources to the internet and adheres to the principle of least privilege by providing direct access to only the required service.
