Go Firewall Rule Self-Service – v0.02

This post will be an overview of the project progress for Firewall Rule Self-Service portal that I am creating with Go.
The code can be found as release v0.02 in my GitHub

The project is to allow non-technical users to create a firewall rule in Terraform. Currently, the project has a single main page, which is the /create-rule page. This is where the user will provide the rule details required, this will test to see if the database has a duplicate rule, if so an error message is displayed. If the rule is unique, then a summary page is displayed and a Terraform file is appended in the root of the project directory.

resource "ciscoasa_access_in_rules" "1.1.1.1_172.16.1.10_9001" {
  interface = "OUTSIDE"
  rule {
    source              = "1.1.1.1"
    destination         = "172.16.1.10"
    destination_service = "tcp/9001"
  }
}

The Terraform file called cisco_asa_terraform.tf is created, and each rule is appended as a resource. This Terraform configuration is still to be tested, but this is the idea currently.

resource "ciscoasa_access_in_rules" "1.1.1.1_172.16.1.10_9001" {
  interface = "OUTSIDE"
  rule {
    source              = "1.1.1.1"
    destination         = "172.16.1.10"
    destination_service = "tcp/9001"
  }
}
