A.2.1 Introduction
Tactical Software redirectors use TCP/IP network connections to carry data that PC applications read and write
on COM ports. By using a network, redirectors introduce two security concerns:
1. How can the identity of both ends of a connection be guaranteed?
2. Is the data in the transmission secure?
In many cases, these issues are sufficiently addressed by the design of the local area network and restricted
physical access to systems and communications equipment.
To meet the greater security requirements of some applications, Tactical Software offers a SSL/TLS Security
option that adds SSL/TLS encryption and certificate features to Tactical products. With the SSL/TLS Security
option, Tactical products gain data security with encryption and authentication with certificates, matching or
exceeding the level of security offered by conventional modem or serial connections.
The SSL/TLS Security features are available only by the use of special Tactical license keys that enable built-in
encryption software, which is otherwise not functional in the Tactical product. Once enabled, settings controlling
the encryption features become available in the Tactical product's Control Panel and its Advanced Settings
window. In the case of the COM/IP Redirector, its built-in software modem also can configure the security-related
settings using AT commands.
Important Note Regarding Export
Tactical Software products with the SSL/TLS Security features enabled are subject to regulations of the U.S.
government and other authorities. Export or re-export of such products is prohibited without the permission of
Tactical Software.
