How do you secure Jenkins?
By default, Jenkins 1.x does not perform any security checks. But, you can manually change that by customizing access controls and configuring it as per one’s need.
Access control locks down access to the Jenkins UI Console and users may log in to get access via Passwords.
One more feature in Jenkins for security is the additional subsystems to prevent direct and indirect attacks on the system.
