DECOIT SIEM-GUI (iMonitor edition)

The DECOIT SIEM-GUI was developed during the iMonitor and SIMU research projects, while this repository contains the iMonitor version of it. Developed as a Java web application it serves as the administrator front-end of the SIEM system developed in that project. It is based on the Spring Framework version 4.1 and makes heavy use of advanced technologies such as WebSockets. The back-end of the SIEM-GUI was developed as a Java web application that runs on a Apache Tomcat 8 application server. It serves a web-interface written with AngularJS to allow users of the SIEM system access to detected incidents and raw event data.


To use the SIEM-GUI several steps are required in advance to make sure everything builds and runs fine. It relies on a number of external services and tools.

  • Java 8
  • Maven 3
  • Icinga
  • Request Tracker (RT)
  • DECOIT RT-Connector
  • iMonitor Correlation engine
  • Apache Tomcat 8

Java 8 and Maven 3

Maven is required to build this project. The SIEM-GUI uses Java 8 features and thus a Java 8 (preferably Oracle JDK) is required. It will not run on Java 7 or below!


The iMonitor project uses Icinga as an event aggregator. A running instance must we accessible by the SIEM-GUI installation. Icinga must be configured to store its event log into a database and access to that database is required for the SIEM-GUI to access the raw event data.

Request Tracker (RT)

The ticket system RT is required by the SIEM-GUI as well. It serves as user management system and ticket system to track incident processing. RT must be accessible via HTTP or HTTPS by the SIEM-GUI and required some additional configuration. Please refer to the section Configuration below, the detailed configuration of RT is described there.

DECOIT RT-Connector

To access the REST API of RT our RT-Connector is required. It can be downloaded here. Instruction how to build and install it can be found there as well.

iMonitor Correlation engine

The SIEM-GUI depends on several libraries provided by the iMonitor correlation package. It can be downloaded from the project website. Instructions how to install the libraries and setup the correlation can be found inside the archive file. The dependencies must be installed in your local Maven repository before building the SIEM-GUI.

Apache Tomcat 8

The Apache Tomcat 8 application server is required to serve the SIEM-GUI WAR file. It must be configured to use a Java 8 JRE. If you are planning to use RT via HTTPS the server for RT must be configured properly and the certificate file must be importet into the TrustStore that will be used by the Tomcat domain that serves the SIEM-GUI application. Please refer to the RT-Connector documentation for information on how to setup a proper certificate and import it into a key store file.
