Building a Reasonably Safe Travel Burner Laptop

International travel can be difficult, and for a security conscious person especially so.

In this video from t2’15 Georg Wicherski demonstrates a way of solving many problems related to carrying a personal computing device with you. For a person crossing borders on a regular basis or otherwise in need of heightened security for their laptop, this is a must see. Enjoy!

Do note that this has been actually implemented in practice instead of being just intellectual mastu^H^H^H a mental exercise. For more details about the setup, refer to the github repository. The setup has been since updated to support TPM remote attestation.

If Attackers Can Use Graphs, Then Why Can’t We?

Those in the business of securing enterprises and organizations should definitely watch OlleB‘s presentation from t2’15. Moving from point-in-time <insert-product-name-here> scans to a more structured approach using graphs, attack models, understanding and eradicating vulnerability classes or using safety/assurance cases is a long-term security investment.

Taking your defensive game to the next level requires trying out new approaches to old problems and sometimes challenging the conventional wisdom. This video should give you food for thought – it’s one of our favorites!

Nano-Scale Red Teaming

If you want to learn how to apply defensive measures to protect offensive operations and your capabilities, Jacob Torrey’s “Nano-Scale Red Teaming: Making REs Cry With Device-Specific Opaque Execution” from t2’16 is the presentation to watch.

The wealth of knowledge presented on how to create trusted implants via physically uncloneable functions and encrypted execution is not limited to just theory as Jacob and Assured Information Security, Inc have released PUFlib on github.

Live long and persist!
