Protection Against Ransomware – a Subjective Overview

antivirus. Binary code, technology background

The threat posed by ransomware such as Locky and other malware has been a hot topic on and off in the media for months now. In a number of cases, including some rather more prominent ones, hackers have managed and continue to manage to infect their victims’ files with malware, which encrypts them to the point where they can no longer be used – the files are only made available again once a “ransom” has been paid. The more accesses the user in question has, the higher the damage: if possible, files on servers in the network are also “captured”.

A great deal has already been written on the topic. At this point, I would like – albeit very subjectively – to introduce a couple of approaches for how to protect yourself against such attacks.

Manage Local System Configuration in UCS with UCR

UCR is the central tool for the management of the local system configuration of a UCS-based system. It releases you from the manual editing of sensitive configuration files.

In this video tutorial we explain how you can easily administrate your local system configuration in Univention Corporate Server via Univention Configuration Registry (UCR).

Through the integration of the software Samba in Univention Corporate Server we provide you with Microsoft Windows Services.

In this video we like to explain you the basic concept behind the software Samba in UCS and present you two of the most widely used UCS extensions. These are the Microsoft Active Directory compatible domain controller and the Windows compatible member server.

Join a Windows Client to a UCS Domain

You cannot only join further UCS servers to an existing UCS domain but also various clients. After the join you can manage and configure these clients easily via the Univention Management Console from anywhere you are. Among those administrative tasks are, for example, the installation of software, the monitoring and controlling of services, and the network configuration.

In this article and in the video below I will show you in detail how easy that is.

An Introduction to the Univention Management Console

The Univention Management Console (UMC) is the graphical web interface of Univention Corporate Server. In the following video, I would like to explain you the most important features and functions of this tool.

Synchronisation between UCS and Microsoft Windows with Samba Active Directory

In “Fail-safe performance and load distribution thanks to LDAP replication” I focused on describing the UCS OpenLDAP directory service. Unfortunately, OpenLDAP is only of comparatively little help to me if I want to operate Windows systems in my network, as Windows doesn’t speak the standard-compliant LDAP protocol as a rule, but rather a particular dialect that Microsoft selected for its Active Directory. I would now like to explain which technologies integrated in Univention Corporate Server we can use to deal with this situation and go into more detail about the replication via listener/notifier for OpenLDAP, DRS replication for the Active Directory and the “Univention S4 Connector”, which synchronises between the two worlds.
