AWS IAM Roles: AWS Identity and Access Management (IAM) roles allow for permissions to be assigned to AWS resources without the use of static credentials. Roles provide temporary credentials that are automatically rotated.

Service Role: The ‘get-pics’ service role created by Rebecca includes a permission policy for read-only access to the S3 bucket and a trust policy that allows the EC2 instance to assume the role.

Temporary Credentials: When the application runs on the EC2 instance, it uses the temporary credentials provided by the role to access the S3 bucket. These credentials are dynamically provided and do not require developer management.

Developer and Admin Roles: Since the EC2 instance has the necessary permissions through the service role, the developer does not need to manage credentials. Similarly, the admin does not need to grant explicit permission to the developer because the permissions are already encapsulated within the role.

Security Best Practices: This approach adheres to AWS security best practices by avoiding the sharing of static credentials and minimizing the need for manual credential management.

To encrypt the traffic between the load balancer and clients that initiate SSL or TLS sessions, SecAppSol Pvt. Ltd.'s security team would enable an HTTPS listener on their load balancer. This is a common method used in AWS to secure communication.

Here’s how it works:

HTTPS Listener Configuration: The security team configures the load balancer with an HTTPS listener, which listens for incoming SSL or TLS connections on a specified port (usually port 443).

SSL/TLS Certificates: They deploy SSL/TLS certificates on the load balancer. These certificates are used to establish a secure connection and encrypt the traffic.

Secure Communication: When a client initiates a session, the HTTPS listener uses the SSL/TLS certificate to perform a handshake, establish a secure connection, and encrypt the data in transit.

Backend Encryption: Optionally, the load balancer can also be configured to encrypt traffic to the backend servers, ensuring end-to-end encryption.

Security Policies: The security team sets security policies on the load balancer to define the ciphers and protocols used for SSL/TLS, further enhancing security.

Chris Noth is looking to manage user identities and automate the provisioning and de-provisioning of users in cloud-based services and applications. The IAM standard that supports this functionality is SCIM (System for Cross-domain Identity Management).

SCIM Overview: SCIM is an open standard designed to manage user identity information across different domains. It simplifies user management in cloud-based applications and services by allowing for automated user provisioning and de-provisioning1.

Automated Provisioning: With SCIM, when new users are added to an organization’s system, their identities can be automatically provisioned across various cloud services without manual intervention1.

Automated De-provisioning: Similarly, when users leave the organization or their roles change, SCIM can ensure that their access is automatically revoked or adjusted across all connected services. This reduces the risk of former employees retaining access to sensitive systems and data1.

Why Not the Others?:

XACML (eXtensible Access Control Markup Language) is used for defining access control policies, not for identity provisioning.

OpenID is an authentication standard that allows users to be authenticated by certain co-operating sites using a third-party service, without the need for passwords.

OAuth is an open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords.
