Jenkins Security Hardening | Automation Testing Notes

📄️ Jenkins Security Hardening – Overview

This section focuses on securing Jenkins controllers, agents, pipelines, and integrations.

This document explains how Jenkins identifies users (authentication) and controls what they can do (authorization).

RBAC is the recommended authorization model for production Jenkins.

The Jenkins controller is the most sensitive component in the system.

Jenkins agents execute untrusted and user-controlled code.

Plugins extend Jenkins functionality but also extend its attack surface.

Network exposure is one of the most common Jenkins security failures.

Auditing and monitoring help you detect misuse, attacks, and misconfigurations in Jenkins.
