Collaborative Cloud Workspace Based on Univention Corporate Server

In this success story, a team which had only worked together online in the past required a stable IT infrastructure of its own with classic, collaborative elements as well as a cloud workspace. Following successful realization of the project, the cooperation can now continue in a virtualized environment with UCS.

In this article, I will be explaining in more detail which hardware and software were employed in the implementation of this project.

Central IdM of Cloud to Minimize Risks with Users and Structures

When administrators think about user management (IdM), they often only keep an eye on traditional IT systems. But even in the cloud, where you can buy new services with just a few clicks, it’s extremely important for companies to keep control over their users if they do not want to lose control over who has rights and access in the organization. Otherwise, a dissatisfied or dismissed employee can quickly become a real threat to the entire corporate IT. Or the failure of subsystems can mean that the entire IT can no longer be accessed and all processes in the company are stopped.

Errata Updates for Spectre and Meltdown Problems

Developers at Google have discovered a problem with processors of several different CPU vendors, which can be exploited by software. Due to these security vulnerabilities, unauthorized users may gain access to supposedly protected memory areas.

These problems, known as “Spectre” and “Meltdown”, are specified by the CVE (Common Vulnerability and Exposures) numbers: CVE-2017-5753, CVE-2017-5715 and CVE-2017-5754. Apparently some of these problems affect most CPUs made by Intel, but also by AMD and ARM, regardless of the operating system in use.

We are currently working hard to provide errata updates for UCS to fix the problem. The current status and links to the errata can be found in the Univention Forum.

I Mattermost now…

I wrote the following article about the ChatOps solution Mattermost on November 26, 2017 for my own Blog “gestreift.net”. As Mattermost has been available in the Univention App Center for a few months now, Univention had the idea to publish this article here for your information, too.

And here we go:

It’s just over a year now since I first wrote about the popularity of Slacking und WhatsApping and explained how to install Rocket.Chat. For a number of reasons, I stumbled across Mattermost a while ago and the time has come to pen a few lines on the how and the why…
