In the rapidly evolving landscape of cybersecurity, regular vulnerability assessments are essential to identify and mitigate potential security risks. The Terrapin Vulnerability Scanner, developed by the RUB-NDS research group, offers a powerful tool for scanning and evaluating the security posture of systems. In this article, we explore how Ansible, a popular automation tool, can be leveraged to streamline the process of deploying and executing the Terrapin Scanner.

Understanding the Ansible Playbook

The provided Ansible playbook is a set of instructions written in YAML format, defining a sequence of tasks to be executed on remote hosts. Let’s break down the key components of the playbook:

- name: Terrapin Vulnerability Scanner
  hosts: all
  gather_facts: false
    scanner: "Terrapin_Scanner_MacOS_arm64_darwin"
    target: ""
    version: "1.1.0"
    myurl: "{{ version }}/{{ scanner }}"
    mydest: "./"
    cli_params: "-json -connect {{ target }}"
    - name: Download the scanner
        url: "{{ myurl }}"
        dest: "{{ mydest }}"
        mode: '0644'

    - name: Set scanner execution permission
        dest: "{{ mydest }}/{{ scanner }}"
        mode: 'a+x'

    - name: Execute the scanner
      ansible.builtin.command: "{{ mydest }}/{{ scanner }} {{ cli_params }}"
      register: command_output

    - name: Print message on the screen
        var: command_output
