What is the first step in the rule writing journey?

The first step in the rule writing journey is identifying sources. This step is crucial because it involves understanding what the potential sources of traffic are—whether those are workloads, applications, or services that need to communicate with one another. By identifying sources, you establish the foundation for building effective security policies.

The process of defining how these sources interact and what permissions or restrictions should be applied comes later in the rule writing process. It ultimately helps you to create precise allow or deny rules based on the specific sources you have identified. Understanding these sources is vital for tailoring the policy to efficiently manage and secure network traffic based on the actual requirements of the environment. Without this initial step, it would be challenging to create rules that accurately reflect the organization’s security posture.
