A healthcare startup stores encrypted patient records in a private Amazon S3 bucket in its production AWS account. An internal compliance officer (an IAM user in the same account) requires read-only access to these records for auditing. Simultaneously, an automated diagnostic application running in an external partner's AWS account must upload new patient reports directly to the same bucket. The startup's security policy prohibits sharing credentials or setting up cross-account identity federation. Which of the following configurations represents the most secure, AWS-recommended approach to grant the required access?

Cevabı ve açıklamayı göster

Cevap: Attach an identity-based policy to the compliance officer's IAM user granting read access, and attach a resource-based policy (bucket policy) to the S3 bucket granting write access to the partner's external AWS account.

Cevap

Attach an identity-based policy to the compliance officer's IAM user granting read access, and attach a resource-based policy (bucket policy) to the S3 bucket granting write access to the partner's external AWS account.
The correct answer is to attach an identity-based policy to the compliance officer's IAM user granting read access, and attach a resource-based policy (bucket policy) to the S3 bucket granting write access to the partner's external AWS account. Identity-based policies are optimal for managing access for users in the local account, while resource-based bucket policies are the most secure way to grant cross-account permissions directly without requiring the creation of local IAM users, the sharing of credentials, or the setup of full cross-account role assumption.

Adım Adım Çözüm

1
Analyze the access requirements for the internal user.
The internal compliance officer is an IAM user in the same AWS account. An identity-based policy attached directly to the user (or their group) is the standard and most secure way to grant read access to S3.
Identity-based policies are designed to manage permissions for identities within the local account.
2
Analyze the access requirements for the external partner's application.
The application runs in an external AWS account. To grant cross-account access without sharing credentials, a resource-based S3 bucket policy should be configured to trust the external account's ARN or identity.
S3 bucket policies (resource-based) can directly grant cross-account access, eliminating the need to create IAM users or share long-term credentials.
3
Combine the configurations and evaluate best practices.
The combination of an identity-based policy for the internal user and a resource-based bucket policy for the external partner's application provides the most secure configuration while adhering to the principle of least privilege.
This avoids creating unnecessary IAM users with static keys or exposing root credentials, matching AWS security best practices.

Anahtar Kavram

Distinction between identity-based policies (attached to users/groups/roles) and resource-based policies (attached to resources like S3 buckets) for cross-account access.

Cevap: Deploying Amazon Simple Queue Service (Amazon SQS) to decouple the checkout system from the backend payment processing service; Implementing a microservices architecture where services communicate via standard web APIs

Cevap

Deploying Amazon Simple Queue Service (Amazon SQS) to decouple the checkout system from the backend payment processing service, and implementing a microservices architecture where services communicate via standard web APIs
AWS Cloud architecture principles emphasize loose coupling, which minimizes dependencies between systems. Deploying Amazon Simple Queue Service (Amazon SQS) acts as a buffer between components, preventing failures in the downstream payment processor from impacting upstream checkout functions. Similarly, a microservices architecture communicates over web APIs, isolating services so that issues in one do not disrupt the availability of others.

Adım Adım Çözüm

1
Identify the primary requirement: preventing a failure in one component from taking down other components.
This requirement aligns with the AWS Cloud design principle of loose coupling and isolation of failures.
By reducing dependencies between components, system reliability and resilience are enhanced.
2
Evaluate the choices to find which options promote decoupling.
Using message queues like Amazon SQS and building a microservices architecture using APIs are standard patterns to achieve loose coupling.
These solutions separate boundaries of responsibility and failure between components.

Cevabı ve açıklamayı göster

Cevap: Enable multi-factor authentication (MFA) on the AWS account root user and create individual IAM users for daily administrative tasks.; Configure the application servers to use IAM roles with temporary credentials instead of long-term access keys.

Cevap

Enable multi-factor authentication (MFA) on the AWS account root user and create individual IAM users for daily administrative tasks, and configure the application servers to use IAM roles with temporary credentials instead of long-term access keys.
The correct actions are securing the root user with multi-factor authentication (MFA) while using individual IAM users for daily administrative activities, and configuring application servers to use IAM roles with temporary credentials rather than long-term access keys. These actions adhere to the principle of least privilege, guarantee auditability, and minimize the risk of compromised long-term credentials.

Adım Adım Çözüm

1
Analyze the security risk of using the AWS account root user for daily configuration tasks.
The root user possesses unrestricted privileges that cannot be locked down. Continued operational use increases the attack surface.
AWS security standards state that the root user should be secured with MFA and restricted to a tiny subset of account-level administrative actions.
2
Address the risk of hardcoded long-term credentials on application servers.
Long-term access keys are permanent until rotated manually, presenting a leak risk if credentials are checked into repositories or compromised.
AWS recommends replacing static credentials with IAM roles, which leverage short-term, temporary security credentials that rotate automatically.
3
Evaluate and discard insecure administrative models.
Shared credentials (like shared IAM users or shared root accounts) break audit trails, and requesting AWS to manage client keys violates the Shared Responsibility Model.
Every administrator must have a unique identity, and the customer retains operational control over IAM configuration.

Cevap: Configuring VPC security groups to restrict network access to the cache cluster nodes

Cevap

Configuring VPC security groups to restrict network access to the cache cluster nodes
The correct answer is configuring VPC security groups to restrict network access to the cache cluster nodes. Under the AWS Shared Responsibility Model, firewall configuration and network access controls (such as security groups) are always the customer's responsibility, regardless of whether the service is IaaS or a managed database/cache service.

Adım Adım Çözüm

1
Analyze the service type in the scenario.
Amazon ElastiCache for Redis is a managed database/caching service.
Managed services shift the management of the underlying physical infrastructure, operating system, and database software patching to AWS.
2
Determine the boundary of customer responsibility for managed services under the Shared Responsibility Model.
The customer remains responsible for data protection, identity and access management (IAM), and network traffic configuration (such as security groups).
This isolates the customer's responsibility to security 'in' the cloud, specifically network firewall rules and access credentials.
3
Evaluate the choices to find the one matching the customer's responsibility.
Configuring VPC security groups is a customer task, whereas patching the guest OS, maintaining physical security, and performing physical audits are AWS responsibilities.
This correctly identifies the boundary of network security configuration for ElastiCache nodes.
