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.

In the event of a security issue on the cloud, such as a DDoS attack or illegal activities, Incident Handlers are typically the first responders. Their role is to manage the initial response to the incident, which includes identifying, assessing, and mitigating the threat to reduce damage and recover from the attack.

Here’s the role of Incident Handlers as first responders:

Incident Identification: They quickly identify the nature and scope of the incident.

Initial Response: Incident Handlers take immediate action to contain and control the situation to prevent further damage.

Communication: They communicate with internal stakeholders and may coordinate with external parties like law enforcement if necessary.

Evidence Preservation: Incident Handlers work to preserve evidence for forensic analysis and legal proceedings.

Recovery and Documentation: They assist in the recovery process and document all actions taken for future reference and analysis.
