  • [AWS CCP] 23, AWS Secrets and Parameter Management
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - AWS Secrets Manager is the correct choice for scenarios requiring automatic credential rotation, such as for RDS databases.
    - AWS Systems Manager Parameter Store is ideal for storing static configuration data and secrets that do not need automated rotation.
    - The primary differentiator tested on the AWS CCP exam between the two services is the automatic rotation feature of Secrets Manager.
    - Parameter Store is generally the more cost-effective solution, especially for a large number of standard parameters without rotation needs.
    - Both services integrate with AWS KMS for encryption and IAM for access control, but only Secrets Manager can generate random secrets.

  • [AWS CCP] 22, Identity Federation and SSO
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - AWS IAM Identity Center is the primary service for managing single sign-on (SSO) for your internal workforce across multiple AWS accounts and applications.
    - Amazon Cognito is designed for customer-facing identity management, allowing users of your web and mobile apps to sign up and sign in via social providers or email.
    - The most critical exam distinction is the user type: IAM Identity Center is for internal employees, while Cognito is for external customers of an application.
    - SAML 2.0 is the underlying open standard protocol that enables identity federation by exchanging authentication data between an identity provider and AWS.
    - A common exam trap is to present a scenario and force a choice between IAM Identity Center and Cognito; correctly identifying the user as 'workforce' or 'customer' is the key to the right answer.

    - AWS WAF is a web application firewall that protects against application-layer (Layer 7) attacks like SQL injection and cross-site scripting.
    - Amazon CloudFront acts as a first line of defense by absorbing and distributing attack traffic at its global edge locations before it reaches your origin.
    - A complete DDoS strategy involves layering these services: CloudFront at the edge, protected by Shield, with WAF filtering application-specific traffic.

  • [AWS CCP] 18, Network Security on AWS
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - Security Groups are stateful firewalls at the instance level, while NACLs are stateless firewalls at the subnet level.
    - "Stateful" means return traffic is automatically allowed, whereas "stateless" requires explicit outbound rules for return traffic.
    - A public subnet is defined by having a route table entry that points to an Internet Gateway (IGW).
    - To explicitly block a specific IP address, you must use a NACL, as Security Groups only support "allow" rules.
    - Troubleshooting network connectivity requires checking both the instance's Security Group and the subnet's NACL.
