How can you set up a security perimeter to prevent data exfiltration while allowing project communication?

1. Establish IAM roles for each project

2. Deploy a separate network for each project

3. Use an infrastructure-as-code tool for a single service perimeter

4. Implement a complex firewall policy for all projects

The correct answer is: Use an infrastructure-as-code tool for a single service perimeter

Setting up a security perimeter to prevent data exfiltration while allowing project communication can be effectively achieved by using an infrastructure-as-code tool for a single service perimeter. This approach allows organizations to define and manage security policies programmatically, ensuring consistent enforcement of security measures across their cloud environment. By utilizing infrastructure-as-code, you can create a single service perimeter that encapsulates all the resources within specified projects. This perimeter controls the flow of data and access between projects, allowing only approved communication paths while restricting data egress to the outside world. This method is both scalable and efficient, allowing for rapid changes and updates as the organization's security landscape evolves. This solution also minimizes the administrative overhead associated with managing separate security policies for each project and ensures that security requirements are uniformly applied, reducing the risk of misconfigurations that could lead to data leaks. While the other choices may provide some level of security, they don't effectively address the need for a coherent, central management strategy for project communication and data protection. For example, establishing IAM roles for each project focuses primarily on access controls rather than broad network security, deploying a separate network for each project introduces complexity and isolation that may hinder necessary communication, and implementing a complex firewall policy can become unwieldy and difficult to manage as
