Who Is Twentyseven34

A Portland Oregon area security architect, focusing on product security issues.

David Grawrock is a well-known security architect with a history of successful security products. He is an inventor, designer, evangelist, and visionary. He has brought both software and hardware products to market including Intel's Trusted Execution Technology and the Trusted Computing Group's Trusted Platform Module.

After over 17 years at Intel, David is now looking at providing security architecture help to Boards of Directors and Boards of Advisers. 

Twentyseven34 is a double play on words.

First, David is the editor for ISO/IEC 27034 part 7. 

Second, David is the father of seven children. 

The number seven plays an important role in his life and this became the genesis for the name.
