Chapter 2 — Networking, Security, and Support Connectivity <br />CHAPTER 2 - NETWORKING, SECURITY, AND <br />SUPPORT CONNECTIVITY <br />3.1 INFORM CAD AND ACTIVE DIRECTORY <br />The server and workstation -based components of a TriTech system rely upon an effectively functioning <br />Windows -based network TriTech strongly recommends that Inform CAD systems be implemented on an <br />isolated network and not to attach the CAD domain to the customer's existing Active Directory infrastructure. <br />Recommended Example: <br />Two Actin Di�rc,41oryv Sowers PCs) <br />TriTech Servers. Trite¢h Woirkst<itions <br />TriTech's network recommendations are as follows: <br />/ Group Policies - Newly deployed Group Policies from the WAN side Active Directory can interfere with <br />Inform CAD/Inform application(s). <br />TriTech has identified significant problems with TriTech applications, including Inform CAD, at customer <br />sites due to a Group Policy that was applied. Group Policy related issues may sometimes be difficult to <br />identify and troubleshoot. <br />1 Organizational Unit - If the CAD system is part of an existing Active Directory, all the CAD users/groups <br />and computers should be moved to a separate Organizational Unit (OU). `Block Policy inheritance' should <br />then be enabled on that OU. <br />► Pirewalls - TriTech recommends separating the CAD network from the rest of the WAN and using <br />firewall(s) between the CAD network and the WAN. <br />1 Security Patches - TriTech cannot always guarantee that the latest operating system service packs and <br />security patches will be compatible with TriTech applications. Therefore, systems running Inform CAD <br />may become vulnerable and if they are art of an existing Active Directory infrastructure/network, exposed <br />to possibility of being affected by a virus or an Internet worm. <br />1 Static IP Addresses - Based upon problems experienced at customer sites, TriTech strongly recommends <br />the use of static IP addresses for an Inform CAD System. <br />The contents of this material are confidential and proprietary to TriTech Software Systems, Inc. and may not be reproduced, <br />published or disclosed to others without the prior written consent of TriTech Software Systems, Inc. <br />©2015 TriTech Software Systems <br />
