| A high security Pre-scan Encryption software for a
leading international financial services provider: The company is one of the largest financial institutions in the world. A leading Information Technology innovator, the company has been rated highly for effective use of technology. The client's business is information intensive as it is heavily dependent on timely exchange of crucial and sensitive information such as rates, trades and transfers and its rapid interpretation by people in different parts of the world. To serve its global enterprise needs, the company implemented a worldwide network of diverse machines. The size of the network can be gauged from the fact that the New York office alone had 264 file servers running Novell NETWARE, in addition to numerous gateways and routers. Given the sensitivity of this data, the security of information traveling on this vast network is a critical issue. Information on the network must be protected from unauthorized users who may be deliberately tapping the network. A Security Access Server system was implemented to meet these objectives by providing a unified and highly secure login facility to various servers on the worldwide network. To keep information secure from unauthorized access yet allow authorized access over telephone lines, all data was encrypted at the operating system level. The ODI prescan encryption layer module performed this task. Such driver level encryption differs from application level encryption in two ways, the applications whose data streams are being encrypted do not need to know about the encryption and driver level encryption is significantly faster at almost real-time speed. This module now runs on environments as diverse as DOS, OS/2 and Novell NETWARE. It can encrypt various protocols like IPX, TCP/IP and NETBIOS packets. The system has been completed for DOS and OS/2 for the IPX protocol and has been implemented in 32-bit 80386-80486 ASSEMBLER and C code. It consists of about 15,000 lines of code. Novell API for DOS, Novell SDK for OS/2 and Novell SDK for NLM development were utilized. Top |
