# Tools Explored in this course

> This course explores essential security tools for hardening CI/CD pipelines in a DevSecOps context.

In this DevSecOps–focused course, you’ll discover essential security tools and technologies that harden your CI/CD pipeline. This lesson provides a high-level introduction to each tool, covering:

* What the tool does
* Why it matters in a secure CI/CD workflow
* How it integrates into your overall DevSecOps process

## Course Structure

We’ll explore each category over four detailed sections:

1. Static Code Analysis
2. Dependency & Package Management
3. Container & Infrastructure Scanning
4. Runtime Protection & Secrets Management

## Running Example: Spring Boot Application

All demonstrations use a [Spring Boot](https://spring.io/projects/spring-boot) application. While some tools are Spring Boot–specific, the concepts and workflows apply broadly across other ecosystems.

## Ecosystem-Specific Recommendations

Many of the security tools we cover support multiple languages and frameworks. Here are links to the official sites for alternative ecosystems:
