to help build a centralized system to enable broad monitoring of the Internet and, potentially, surveillance of its users.

The proposal is part of a final version of a report, ``The National Strategy to Secure Cyberspace,'' set for release early next year, according to several people who have been briefed on the report. It is a component of the effort to increase national security after the Sept. 11, 2001, attacks.

The president's Critical Infrastructure Protection Board is preparing the report, and it is intended to create public and private cooperation to regulate and defend the national computer networks, not only from everyday hazards such as viruses but also from terrorist attack.

Ultimately, the report is intended to provide an Internet strategy for the new Department of Homeland Security.
