Advanced Jenkins setups often use Security scanning tools to detect vulnerabilities in the Jenkins environment and its jobs. These tools analyze code, configurations, and dependencies for potential security risks.

For effective Continuous Integration in Jenkins, it is important to have Unit tests that run quickly and reliably. Unit tests focus on individual components, ensuring that each part of the code functions correctly in isolation.

To secure a Jenkins master-slave connection, the use of the HTTPS protocol is recommended. This ensures encrypted communication, protecting sensitive information during data transfer.

The Jenkins JUnit plugin is essential for integrating automated testing frameworks, such as JUnit, into the Jenkins build process. It helps in reporting and visualizing test results within Jenkins.

Project Labels are commonly used in Jenkins to manage different project environments. Labels help in categorizing and directing jobs to specific nodes or agents based on their configurations.

JVisualVM is a sophisticated tool for detailed monitoring of Jenkins nodes and executors. It provides real-time performance and resource usage metrics, aiding experts in optimizing Jenkins performance.

The crucial data to back up for disaster recovery in Jenkins is the Jenkins home directory. This directory contains configuration settings, job configurations, and other essential data for the Jenkins instance.

Running a script outside the Jenkins sandbox environment increases the risk of malicious code execution. The sandbox restricts certain operations to prevent unauthorized access and potential security vulnerabilities.

Multibranch Pipeline jobs in Jenkins provide improved code organization and versioning by automatically creating jobs for each branch in a repository, making it easier to manage and build code changes.

The AWS CodeDeploy plugin is commonly used to integrate Jenkins with AWS. It facilitates the deployment of applications to Amazon EC2 instances.
