Awesome AppSec in Ubuntu

Description

Ubuntu, a mature and user-friendly Linux distribution, is used by developers and security communities alike. Its appeal also lies in the ease of installing handy tools. Ubuntu have two main software distribution channels:

• Ubuntu archive: If software is embraced by Ubuntu or Debian because of its maturity and usefulness, it's distributed as a Debian package. Given the slow release cycle, you can expect only stable versions here. However, it's a double-edged sword - you might miss out on the latest features introduced by the upstream.
• Snap Store: Here's where anyone can play! By simply wrapping your software in a self-contained snap, you can publish it in the Snap Store. With no restrictions on release cycles, maintainers can publish new versions at their own pace.

This open list curates awesome tools that:

• Assist anyone working with code to ensure or improve the security of a codebase; and
• Can be easily installed on Ubuntu, either from the Ubuntu Archive or the Snap Store.

Categories

The tools were meticulously grouped into categories. To make things more visual, the following diagram outlines each category and how it could potentially fit into your software development lifecycle.
