3.2. Compute Security

Securing your compute resources is a critical part of infrastructure security. This involves applying security best practices to your virtual servers (EC2 instances), containers, and serverless functions to protect them from compromise.

The First Principle is that robust compute security involves hardening operating systems, securing container images and runtimes, and strictly controlling permissions for serverless functions, fundamentally protecting your application's execution environment.

You will learn about securing EC2 instances, containers, and serverless applications.

The focus is on comprehending how to implement and maintain these compute-level security measures, which is crucial for the SCS-C02 exam.

Scenario: You are responsible for securing a new application that runs on a mix of EC2 instances, Docker containers, and Lambda functions. You need to ensure each compute environment is protected from vulnerabilities and unauthorized access.

Reflection Question: How does robust compute security (e.g., patching, hardening, container image scanning, Lambda permissions) fundamentally protect your application's execution environment by securing operating systems, container runtimes, and strictly controlling permissions for serverless functions?
