Probably, one of the scarier articles I have read. Portends
more danger for the business environment as an entire generation
growing up using such software migrate into the corporate world
over the years.
While the solutions recommended in the article will help, they
address only part of the problem. Even Full Disk Encryption (FDE)
is not a solution, as P2P networks operate only when a legitimate
user has booted up the machine (by which time the FDE software is
already decrypting everything for applications).
The only long-term solution with the smallest attack-surface is:
Policy + Enforcement + Education + Application-level encryption
requiring the authentication of users before decrypting content.
