Utilizing CloudFront signed cookies is the simplest and most effective way to protect HLS video content for paying subscribers. Signed cookies provide access control for multiple files, such as video chunks in HLS streaming, without the need to generate a signed URL for each video chunk. This method simplifies the process for long video events with thousands of chunks, enhancing user experience while ensuring content protection.

Option A is incorrect since you don't add a user to the IAM Role

Option C is incorrect since you don't assign multiple users to a policy

Option D is incorrect since this is not an ideal approach

An IAM group is used to collectively manage users who need the same set of permissions. By having groups, it becomes easier to manage permissions. So if you change the permissions on the group scale, it will affect all the users in that group

For more information on IAM Groups, just browse to the below URL:

The correct answer is: Use the IAM groups and add users, based upon their role, to different groups and apply the policy to group

The reason is that this solution will meet the requirements of collecting, reviewing, and managing the evidence from both on-premises and AWS resources to demonstrate compliance with company policy. According to the web search results12, “AWS Audit Manager helps you continuously audit your AWS usage to simplify how you manage risk and compliance with regulations and industry standards. AWS Audit Manager makes it easier to evaluate whether your policies, procedures, and activities—also known as controls—are operating as intended.” The results1 also state that “In addition to the evidence that Audit Manager collects from your AWS environment, you can also upload and centrally manage evidence from your on-premises or multicloud environment.” Therefore, by creating an assessment in AWS Audit Manager, the security engineer can use a prebuilt or custom framework that contains the relevant controls for the company policy, upload manual evidence from the on-premises workloads, and add the evidence to the assessment. After Audit Manager collects the necessary evidence from the AWS resources, the security engineer can generate an assessment report that includes all the evidence from both sources.

The other options are incorrect because:

B. Install the Amazon CloudWatch agent on the on-premises workloads. Use AWS Config to deploy a conformance pack from a sample conformance pack template or a custom YAML template. Generate an assessment report after AWS Config identifies noncompliant workloads and resources. This option is not sufficient to meet the requirements, because it does not collect or manage the evidence from both sources. It only monitors and evaluates the configuration compliance of theworkloads and resources using AWS Config rules. According to the web search results3, “A conformance pack is a collection of AWS Config rules and remediation actions that can be easily deployed as a single entity in an account and a Region or across an organization in AWS Organizations.” However, a conformance pack does not provide a way to upload or include manual evidence from the on-premises workloads, nor does it generate an assessment report that contains all the evidence.

C. Set up the appropriate security standard in AWS Security Hub. Upload manual evidence from the on-premises workloads. Wait for Security Hub to collect the evidence from the AWS resources. Download the list of controls as a .csv file. This option is not optimal to meet the requirements, because it does not provide a comprehensive or audit-ready report that contains all the evidence. It only provides a list of controls and their compliance status in a .csv file format. According to the web search results4, “Security Hub provides you with a comprehensive view of your security state within AWS and helps you check your environment against security industry standards and best practices.” However, Security Hub does not provide a way to upload or include manual evidence from the on-premises workloads, nor does it generate an assessment report that contains all the evidence.

D. Install the Amazon CloudWatch agent on the on-premises workloads. Create a CloudWatch dashboard to monitor the on-premises workloads and the AWS resources. Run a query on the workloads and resources. Download the results. This option is not sufficient to meet the requirements, because it does not collect or manage the evidence from both sources. It only monitors and analyzes the metrics and logs of the workloads and resources using CloudWatch. According to the web search results, “Amazon CloudWatch is a monitoring and observability service built for DevOps engineers, developers, site reliability engineers (SREs), and IT managers.” However, CloudWatch does not provide a way to upload or include manual evidence from the on-premises workloads, nor does it generate an assessment report that contains all the evidence.

By disabling SSL termination, you are leaving an unsecure connection from the ELB to the back end instances. Hence this means that part of the data transit is not being encrypted.

Option B is incorrect because this would not guarantee complete encryption of data in transit

Option C and D are incorrect because these would not guarantee encryption

The correct answer is: Use S3 SSE and use SSL for data in transit

The correct answer is A. Revoke all versions of the signing profile assigned to the developer.

According to the AWS documentation1, AWS Signer is a fully managed code-signing service that helps you ensure the trust and integrity of your code. You can use Signer to sign code artifacts, such as Lambda deployment packages, with code-signing certificates that you control and manage.

A signing profile is a collection of settings that Signer uses to sign your code artifacts. A signing profile includes information such as the following:

The type of signature that you want to create (for example, a code-signing signature).

The signing algorithm that you want Signer to use to sign your code.

The code-signing certificate and its private key that you want Signer to use to sign your code.

You can create multiple versions of a signing profile, each with a different code-signing certificate. You can also revoke a version of a signing profile if you no longer want to use it for signing code artifacts.

In this case, the company wants to ensure that all the code that the developer wrote can no longer be deployed to the Lambda functions. One way to achieve this is to revoke all versions of the signing profile that was assigned to the developer. This will prevent Signer from using that signing profile to sign any new code artifacts, and also invalidate any existing signatures that were created with that signing profile. This way, the company can ensure that only trusted and authorized code can be deployed to the Lambda functions.

The other options are incorrect because:

B. Examining the developer’s IAM roles and removing all permissions that grant access to Signer may not be sufficient to prevent the deployment of the developer’s code. The developer may have already signed some code artifacts with a valid signing profile before leaving the company, and those signatures may still be accepted by Lambda unless the signing profile is revoked.

C. Re-encrypting all source code with a new AWS Key Management Service (AWS KMS) key may not be effective or practical. AWS KMS is a service that lets you create and manage encryption keys for your data. However, Lambda does not require encryption keys for deploying code artifacts, only valid signatures from Signer. Therefore, re-encrypting the source code may not prevent the deployment of the developer’s code if it has already been signed with a valid signing profile. Moreover, re-encrypting all source code may be time-consuming and disruptive for other developers who are working on the same code base.

D. Using Amazon CodeGuru to profile all the code that the Lambda functions use may not help with preventing the deployment of the developer’s code. Amazon CodeGuru is a service that provides intelligent recommendations to improve your code quality and identify an application’s most expensive lines of code. However, CodeGuru does not perform any security checks or validations on your code artifacts, nor does it interact with Signer or Lambda in any way. Therefore, using CodeGuru may not prevent unauthorized or untrusted code from being deployed to the Lambda functions.

To ensure that the load balancer only accepts connections over port 443, the security engineer should do the following:

Create a security group with a single inbound rule that allows connections from 0.0.0.0/0 on port 443. This means that the security group allows HTTPS traffic from any source IP address.

Ensure this security group is the only one associated with the ALB. This means that the security group overrides any other rules that might allow HTTP traffic on port 80.

this is the accurate reflection of the access control mechanisms that the Architect should verify. Access control mechanisms are methods that regulate who can access what resources and how. Security groups and network ACLs are two types of access control mechanisms that can be applied to EC2 instances and subnets. Security groups are stateful, meaning they remember and return traffic that was previously allowed. Network ACLs are stateless, meaning they do not remember or return traffic that was previously allowed. Security groups and network ACLs can have inbound and outbound rules that specify the source, destination, protocol, and port of the traffic. By verifying the outbound security group configuration on database servers, the inbound security group configuration on application servers, and the inbound and outbound network ACL configuration on both the database and application server subnets, the Architect can check if there are any misconfigurations or conflicts thatprevent the application servers from initiating a connection to the database servers. The other options are either inaccurate or incomplete for verifying the access control mechanisms.
