Terraform
terraformAn agent with terraform on its PATH can apply infrastructure changes. Memnox wraps the binary, reads the command before it runs, and matches it against the table below. Nothing here is a list of what we support: it is what the runtime already classifies, and the strings are the ones a rule matches on.
What it reads to authenticate
Discovery records that these exist and hashes them. It never reads a value, so a scan can say three agents reach this file and never what is inside it.
What it cannot undo
Every one of these carries the alternative a refusal names, which is why an agent takes the alternative and finishes the task instead of stopping.
terraform destroy **terraform.destroy- Denied, it names
terraform plan -destroy, and read itinstead. terraform state rm **terraform.state-rm- the resource survives and is forgotten
What it changes
Allowed by default, and the obvious first thing to put behind ask.
terraform apply **terraform.apply- Denied, it names
terraform planinstead. terraform import **terraform.import
What it only reads
Matched so a rule can say read is fine, rather than leaving it unspoken.
terraform plan **terraform.planterraform show **terraform.show
The rule this writes
[[rules]] name = "terraform-destructive-asks-first" match.actions = ["terraform.destroy"] decision.effect = "ask" decision.reason = "This cannot be undone."
memnox protect --for terraform writes this into memnox.policies.toml from the table above. You can edit it, and the file is yours.
Run npx memnox to find out whether Terraform is actually reachable from your machine. It reads your own disk and needs no account.
