HOB SCS 2.1 (Secure Communications Server)



HOB Secure Communications Server, in short, HOB SCS, enhances the comprehensive security solution HOB RD VPN  with a stable, hardened operating system platform. HOB Secure Communications Server (SCS) is an HOB-developed operating system based on open software technology. HOB SCS does not employ an already existing distribution, rather, HOB SCS is its own, independent distribution.


HOB Secure Communications Server offers a simple and efficient way to acheive secure remote access via the comprehensive security solution HOB RD VPN. HOB Secure Communications Server uses tried and proven open source technology. When deployed together with  HOB SCS, HOB RD VPN has extra advantages in security, stability, performance and scalability.


The addition of HOB SCS makes the comprehensive security solution HOB RD VPN into a complete software appliance. HOB SCS has the benefits of an appliance solution, such as easy installation, administration and maintenance in connection with a secure and stable operating system.


HOB SCS contains not olny all of the functionality needed to operate HOB RD VPN, it also has additional software components which are either directly integrated or avaliable as add-ins (e.g., NTP time server, SSH access).


As HOB SCS can be installed on the hardware of your choice, you get a definite advantage in comparison to hardware-based solutions. Contrary to hardware appliances, with HOB SCS the hardware on which it is installed can be updated or exchanged whenever and however you want. It is also especially well-suited for implementation as a virtualized solution.


After HOB SCS has been installed, you have a secure, hardened operating system at your disposal. No further security settings are required. As it only has the necessary and essential components, the risk of a faulty configuration is minimized. Operation and administration can be carried out without superuser or root login. To ensure continuous security, HOB provides you with updates.


HOB SCS is based on Open Source technology that has been tried and tested extensively. This software has been adapted and extended to ensure optimal operation of HOB RD VPN as regards security, performance and stability.

HOB SCS with HOB RD VPN has been successfully tested on a mid-priced server with 10,000 parallel sessions. Each of these 10,000 concurrent SSL sessions generated simulated RDP data traffic under realistic conditions

Via an installation CD, both the open source-based operating system HOB SCS as well as the comprehensive security solution HOB RD VPN are installed in one operation. After just a few minutes you have a fully functional HOB RD VPN on a secure, hardened open source operating system at your disposal..


HOB SCS with HOB RD VPN includes the HOB Enterprise Access Server and the HOB WebSecureProxy (HOB WSP), the central core of HOB RD VPN. HOB SCS can be, via HOBmin, a browser-based administration and configuration tool, easily and efficiently administrated. Administration tasks are carried out from the browser over HTTPS, i.e., SSL encrypted.


To administrate and configure HOB RD VPN, a Java-based application for both the Enterprise Access Server and for the WebSecureProxy ( WSP) is included.

These fiatures provide you with a comprehensive remote administration for the entire software appliance. Updates and patches, for HOB SCS as well as for HOB RD VPN, can be installed via the administration tool HOBmin.


The WSP uses SSL encryption. HOB SSL supports all current encryption algorithms, including AES (Advanced Encryption Standard), with up to 256-bit key lengths.


The HOB RD VPN configuration data are stored in the central administration component HOB Enterprise Access. HOB Enterprise Access can use either its own integrated database or save the data to an  LDAP server. HOB Enterprise Access supports all conventional LDAP servers as well as Microsoft Active Directory. When HOB Enterprise Access is configured to store data in an LDAP server, the required structures are created via a schema extension.
