Identity and Access Management (IAM) Strategies Flashcards
AWS Certified Solutions Architect Professional SAP-C02 Flashcards
| Front | Back |
| How do Attribute-Based Access Control (ABAC) differ from traditional IAM policies | ABAC assigns permissions based on tags or attributes attached to resources and identities, rather than static roles or users. |
| How do MFA and IAM policies work together to secure access | MFA adds an additional layer of security, and policies can enforce its use by requiring MFA authentication for specific actions. |
| How do resource ARNs impact IAM policies | ARNs specify the exact resource covered by a policy, allowing permissions to be targeted at individual resources. |
| How do Service Control Policies (SCPs) enhance security in AWS Organizations | SCPs define permissions boundaries for accounts in an organization to restrict actions regardless of individual IAM policies. |
| How do you implement fine-grained permissions in IAM policies | Use resource-level permissions, condition keys, and actions to specify precise access rules for your resources. |
| How does Access Analyzer assist with IAM security | Access Analyzer provides insights into resource sharing settings and flags risky or unintended public access permissions. |
| What happens if an IAM policy and SCP contradict each other | The SCP takes precedence, overriding permissions granted by the IAM policy and restricting the account's actions. |
| What is the difference between IAM users and federated identities | IAM users are created and managed in AWS directly, while federated identities leverage external identity providers for authentication. |
| What is the function of AWS Organizations in centralized IAM management | AWS Organizations allows you to group accounts and manage policies across them for centralized control and governance. |
| What is the key advantage of using federated authentication over IAM users | Federated authentication eliminates the need for AWS-managed credentials and integrates existing identity providers for better scalability. |
| What is the purpose of IAM roles in cross-account access | IAM roles allow secure granting of permissions to access resources in another AWS account without exposing credentials. |
| What is the role of SAML in federated authentication | SAML enables single sign-on (SSO) by exchanging authentication data between an identity provider and AWS. |
| When should you use AssumeRole for cross-account access | Use AssumeRole when an entity in Account A needs temporary permissions to access resources in Account B securely. |
| Why should you use a policy generator for complex IAM scenarios | Policy generators help create accurate policies by simplifying syntax and providing templates for fine-grained access management. |
This deck focuses on complex IAM scenarios, including cross-account access, fine-grained permissions, federated authentication, and service control policies in AWS Organizations.
