Infrastructure as Code Security
How plan-stage policy blocks unsafe AWS and Azure infrastructure before deployment, with practical policy testing and enforcement guidance.
What problem does policy-as-code solve that a manual infrastructure change review does not?
A manual review depends on a human noticing a specific misconfiguration, an open security group, an unencrypted storage bucket, in a plan diff that may span hundreds of resources, and that scrutiny has to be repeated consistently by every reviewer on every change. Policy-as-code encodes the same rule once as executable logic and runs it automatically against every plan, so an overly permissive security group is caught the same way on the hundredth change as the first, without depending on which reviewer happened to be paying attention that day.

Terraform Basics
How Terraform's state model, providers, and plan/apply workflow make infrastructure reviewable like code, plus the state pitfalls that trip up teams.
What is Terraform state and why is it required?
State is a JSON file (by default `terraform.tfstate`) that maps every resource block in your configuration to the real-world object Terraform created for it (an AWS instance ID, a DNS record, etc.). Terraform is declarative, your config describes the desired end state, not the steps to get there, so on every run it needs state to compute a diff between what exists now and what the config says should exist. Without state, Terraform would have no way to know whether a resource already exists, needs updating, or was deleted outside of Terraform.
Why is storing Terraform state locally a problem for a team, and what is the standard fix?
Local state is a single file on one person's machine, so another engineer can apply against stale or missing state and create conflicting changes. The standard fix is a remote backend that stores state centrally and supports locking. For the S3 backend, current Terraform supports native lock files with `use_lockfile = true`; DynamoDB-based locking is deprecated. The backend should also encrypt state and keep recoverable versions because state can contain sensitive values.
What is the difference between terraform plan and terraform apply, and why does that separation matter?
`plan` computes and displays the diff between current state and desired config without changing anything; it is a dry run. `apply` executes that diff against real infrastructure. Separating them means a human (or a CI approval gate) can review exactly what will be created, changed, or destroyed before anything actually happens, which is the core safety mechanism that makes infrastructure-as-code safer than manually clicking through a cloud console, nothing changes without a reviewed, explicit plan.
