Telvent's OASyS DNA 7.5 SCADA Successfully Concludes its Initial Evaluation Stage

December 19, 2007

Madrid, December 19, 2007 – Telvent (Nasdaq: TLVT), the IT company for a sustainable and secure world, announced today the successful completion of the first phase of a research and security assessment, guaranteeing the security of the OASyS DNA 7.5 SCADA.

The research project, which began in early 2007, is being developed in collaboration with the Centre for SCADA (NTBS) of the U.S. Energy Department (DOE) and the Idaho National Laboratory, which in turn is collaborating with the private industry to assess and mitigate potential threats on the control systems for critical infrastructure

The goal of the project was to verify the efficiency of the OASyS DNA 7.5 system and data application. NSTB’s experts in security have evaluated and tested the system’s vulnerability by subjecting it to potential attacks. During this first evaluation phase, they have focused on the specific risks associated with the Gas and Oil sectors, as requested by the DOE.

The final report also provided recommendations on measures that could further enhance the overall security of the product. Telvent will soon begin the second evaluation phase of the project supported by the DOE and the INL.

Telvent continues to search for tools to reduce attacks on critical infrastructures’ control systems, such as attacks to telecommunication networks, electricity grids, chemical plants and other energy assets that can cause losses of billions of euros and leave millions of consumers without power for days. Telvent’s commitment is to actively work on improving the security of its system SCADA.
