ASGARD 2.14 Release

by Nov 3, 2022

We’ve just released the new ASGARD Management Center version 2.14 with important new features. This blog posts lists the most important changes in dedicated chapters. The whole change log can be found at the end of the article. 

Broker Network

The Broker Network allows you to proxy connections to an ASGARD through a so called Broker.

The Broker is a hardened connection proxy that brokers connections to an ASGARD Management Center. Brokers can be exposed to the Internet and allow users to roam between the corporate network and their home network without the need for a permanent VPN connection. They can also load balance connections. 

Two more components are required to maintain a Broker Network: a Gatekeeper and a Lobby.

The Gatekeeper is an application layer firewall that filters malformed or unverifiable requests. The Lobby is a dedicated system to manage and accept new request from yet unverified agents.

The use of the new Broker Network and its components is optional and requires a so-called “Broker License”. Please contact us for more details.

ASGARD Query Language

The new ASGARD query language allows to filter the list of assets based on complex conditions.

It can also be used to select targets for scans or other tasks. 

Advanced Target Selection

Currently, the target selection only allows the selection of target groups based on their label. All target groups are combined with a logical OR. 

The new target selection allows you to include and exclude groups of assets based on their tags. 

E.g., you can now create a job that runs on all systems with the tag “linux” and exclude all systems with the tag “munich”. You can also combine them with a logical AND and instruct ASGARD to run tasks only on systems that have e.g. the labels “windows” AND “berlin”.

The result of this change is that you no longer need to label everything you want to select as target.

New Maintenance Tasks

New predefined tasks allow you to reconfigure or move an agent from one ASGARD Management Center to another one. 


Other Important Changes and Improvements

  • Repeated installation of ASGARD agents will not cause duplicate assets
  • Manual deletion of assets from Asset View
  • Multiple UI improvements
  • The new ASGARD agent will not send his agent log via syslog by default anymore. This has to be enabled individually.
