Orchestrating Cloud Network Security with Ansible
In this hands-on lab, you will use Ansible to automate the deployment and validation of cloud network security policies on AWS. Starting with configuring a secure automation environment using dynamic inventory and encrypted credentials, you will build playbooks that declare and enforce Security Group rules across Development and Production environments, and finish by validating network state and policy compliance through automated checks. By the end, you'll have practical experience orchestrating cloud security the NetDevOps way, replacing manual console clicks with version-controlled, repeatable automation.

Challenge
Establish a Secure Cloud Automation Environment with Ansible
- Configure a dynamic inventory using the amazon.aws.aws_ec2 plugin to automatically discover AWS resources.
- Encrypt sensitive credentials using ansible-vault to protect secrets used in automation workflows.
- Define shared global variables for network configuration such as DNS servers, NTP servers, and environment CIDR ranges.
-
Challenge
Enforce Cloud Network Access Control Policies with Ansible
- Use the amazon.aws.ec2_security_group module to declare and enforce the desired state of Security Group rules.
- Apply environment-specific security policies using conditional logic to differentiate Production and Development rules.
- Generate structured compliance reports using Jinja2 templates driven by YAML security policy data.
-
Challenge
Validate Cloud Network State and Security Compliance
- Verify endpoint reachability using the Ansible uri module to ensure required services remain accessible.
- Audit AWS routing tables to confirm traffic is correctly routed and detect potential misconfigurations.
- Implement handlers that trigger notifications when critical Security Group changes occur.
