## Overview

GET Hard is a collection of security scripts intended to help users create more secure machines. The README describes running a selected script but does not document the scripts’ internal calls or detailed behavior, so the graph shows only that entry-point relationship and the documented machine-hardening purpose. Component labels for the memory and framework scripts are based on their filenames.

Main entry points: [`hardasf/desktopharden.sh`](https://github.com/befoul/get-hard/blob/main/hardasf/desktopharden.sh) (Desktop Hardening), [`hardasf/serverharden.sh`](https://github.com/befoul/get-hard/blob/main/hardasf/serverharden.sh) (Server Hardening), [`hardasf/frameworks.sh`](https://github.com/befoul/get-hard/blob/main/hardasf/frameworks.sh) (Framework Hardening), [`malloc/securemalloc.sh`](https://github.com/befoul/get-hard/blob/main/malloc/securemalloc.sh) (Secure Malloc)
