# Securing Linux
This repo creates a usable Linux platform with adequately security for daily, non-production usage.
TODO: add blurb about reasoning
TODO: add blurb about workflow
Make no mistake this set of playbooks are opinionated and come **without any express or implied warranty**.
## Steps in security
1. [Protect data with partitioning and encryption](./terraform/libvirt/ubuntu/cloud_init.yml)
2. [Set useful base tools](./ansible/tasks/base.yml)
3. [Restrict physical access](./ansible/tasks/physical_access.yml)
4. [Restrict network access](./ansible/tasks/network_access.yml)
5. [Track audit-worthy change events](./ansible/tasks/audit_tools.yml)

## Setting up for development
This project uses :
- [Terraform](https://www.terraform.io/)
- [dmacvicar/terraform-provider-libvirt](https://github.com/dmacvicar/terraform-provider-libvirt) for local dev
- [aws](https://registry.terraform.io/providers/hashicorp/aws/latest) for remote dev
- [Ansible](https://www.ansible.com/) for development and evaluation.
- [Taskfile](./Taskfile.yml) contains most of the magic to get this project working.
### Initializing the project
```bash
make init
```
- Ansible-galaxy installs required public roles within [requirements.yml](requirements.yml)
- Vagrant pulling down the most recent versions of the boxes currently configured.
- Creating an [Ansible Vault](https://docs.ansible.com/ansible/latest/user_guide/vault.html) to protect sensitive data such as keys / passwords in an encrypted vault. An example decrypted file can be reviewed [vault-example.yml](inventory/group_vars/vault-example.yml), which will become [vault.yml](inventory/group_vars/vault.yml).
### Encrypting and decrypting the vault
```bash
make enc # encrypt vault.yml
make dec # decrypt vault.yml
```
### Creating the test VMs
```bash
make build
make ping
```
- Vagrant creates test VMs
- Vagrant takes snapshot of the state at _baseline_ to make iterative testing much faster
### Managing the state of the VMs
```bash
make start
make stop
make restore # restore baseline snapshot
make destroy # remove all traces
```
### Reviewing the baseline security official vagrant boxes
```bash
make audit
```
### Running a hardening playbook
```bash
make play
make audit
```
