Performance Improvements to Role Strategy Plugin

The task for my Google Summer of Code program was to improve the performance of the Role Strategy Plugin. The performance issues for Role Strategy Plugin had been reported multiple times on Jenkins JIRA. With a large number of roles and with complex regular expressions, a large slow-down was visible on the Web UI. Even Read more about Performance Improvements to Role Strategy Plugin[…]

Introducing new Folder Authorization Plugin

During my Google Summer of Code Project, I have created the brand new Folder Auth Plugin for easily managing permissions to projects organized in folders from the Folders plugin. This new plugin is designed for fast permission checks with easy-to-manage roles. The 1.0 version of the plugin has just been released and can be downloaded Read more about Introducing new Folder Authorization Plugin[…]

AWS Security Hub Now Generally Available

I’m a developer, or at least that’s what I tell myself while coming to terms with being a manager. I’m definitely not an infosec expert. I’ve been paged more than once in my career because something I wrote or configured caused a security concern. When systems enable frequent deploys and remove gatekeepers for experimentation, sometimes Read more about AWS Security Hub Now Generally Available[…]

First successful use of Jenkins telemetry

Half a year ago we delivered a security fix for Jenkins that had the potential to break the entire Jenkins UI. We needed to change how Jenkins, through the Stapler web framework, handled HTTP requests, tightening the rules around what requests would be processed by Jenkins. In the six months since, we didn’t receive notable Read more about First successful use of Jenkins telemetry[…]

Security spring cleaning

Today we published a security advisory that mostly informs about issues in Jenkins plugins that have no fixes. What’s going on? The Jenkins security team triages incoming reports both to Jira and our non-public mailing list. Once we’ve determined it is a plugin not maintained by any Jenkins security team members, we try to inform Read more about Security spring cleaning[…]

Limitations of Credentials Masking

In the Jenkins project, we ask that people report security issues to our private issue tracker. This allows us to review issues and prepare fixes in private, often resulting in better, safer security fixes. As a side effect of that, we also learn about common misconceptions and usability problems related to security in Jenkins. This Read more about Limitations of Credentials Masking[…]

Remoting-based CLI removed from Jenkins

Close to two years ago, we announced in New, safer CLI in 2.54 that the traditional “Remoting” operation mode of the Jenkins command-line interface was being deprecated for a variety of reasons, especially its very poor security record. Today in Jenkins 2.165 support for this mode is finally being removed altogether, in both the server Read more about Remoting-based CLI removed from Jenkins[…]

Triggering builds with webhooks behind a secure firewall

In this post I wanted to show how you can run Jenkins behind a firewall (which could be a corporate firewall, a NAT’ed network like you have at home) but still receive webhooks in real time from You can generalise this to other services too – such as BitBucket or DockerHub, or anything really Read more about Triggering builds with webhooks behind a secure firewall[…]

The Silence of the Lambs: Inspecting binaries with Jenkins

This is a guest post by Michael Hüttermann. In a past blog post, Delivery Pipelines, with Jenkins 2, SonarQube, and Artifactory, we talked about pipelines which result in binaries for development versions, and in Delivery pipelines, with Jenkins 2: how to promote Java EE and Docker binaries toward production, we examined ways to consistently promote Read more about The Silence of the Lambs: Inspecting binaries with Jenkins[…]
