Download Cyberarms IDDS Version 2.2

Image -screenIDDS is a completely free on-host intrusion detection system. 


If you have not installed Cyberarms IDDS before on your system, please download the ZIP archive and use setup.exe for installation. The installer will install the latest version of Microsoft .NET Framework version 4.0 and the current C++ runtime library.

If you are doing an upgrade install, please use the .msi software installer packet. To avoid a system restart to be required, simply stop the Cyberarms Intrusion Detection Service and close the administration program prior installation.

Download your free Security System:



  • For new installations, start setup.exe. Do not use the .msi file for installation.
  • For upgrade installations, use the .msi file for installation. Stop the Intrusion Detection Service and close the administration program to avoid a system restart.
  • The system does not protect you "out of the box". To make the system work, you have to enable the security agents required by your system after installation (see installation & configuration). The setup process dispays the installation guide automatically in a browser window after installation. Please follow the basic installation steps.

Version 2.1.3

Version 2.1.3 delivers new security agents for Routing and Remote Access (RRAS) and a FileMaker. The security agent for Remote Desktop protection (TLS/SSL agent) was updated to reflect the new TLS/SSL protocol specification used between Windows Server 2012 and Windows 8 (and higher).

In some circumstances, the SQL Server security agent falsely denied access to the system. This happened when connecting from the local host with invalid credentials and named pipes connections. This issue was resolved with version 2.1.3. 

Version 2.1.1

This update contains an agent status icon on the dashboard to see which agents are enabled. This was introduced to improve software usability.

Manual removal of IP addresses from the firewall rule resulted in an unrecoverable state of the lock object. This was corrected with version 2.1.1
