Security threats are increasing in volume, diversity, and sophistication at the same time that high-value, sensitive data is more commonly being generated, used, and stored on standard business PCs. While the traditional focus of network protection has been on servers and network access devices, these PCs are typically lightly protected, coupled with the fact that a compromised PC may offer the means to obtain access to servers and other network assets, these characteristics have created an incentive for hackers to focus their efforts on client computing platforms.
In Dynamics of a Trusted Platform David Grawrock has updated his highly popular Intel Safer Computing Initiative with new topics covering the latest developments in secure computing. The reader is introduced to the concept of Trusted Computing and the building block approach to designing security into PC platforms. The Intel® Trusted Execution Technology† (Intel® TXT) is one of those building blocks that can be used to create a trusted platform by integrating new security features and capabilities into the processor, chipset, and other platform components.
Building blocks of a trusted platform discussed in this book include:
- Evidence/measurement, reporting/attestation, TCB management, policy engine and PII handling
- Randomness, sequencing, protected storage, detection and inspection, and architectural performance
- Isolation and trusted channel
- External access
- Protected execution
In this concise book, the lead architect for Intel’s security initiative provides critical information you need to evaluate Trusted Computing for use on today’s PC systems and to prepare your designs to respond to threats. A must-read for all hardware and software architects and developers engaged in the PC computing and IT industries—this book will arm the reader with the knowledge required to understand the design of a trusted computer.
