Surveillance Self-Defense (SSD) exists to answer two main questions:
What can the government legally do to spy on your computer data and
communications? And what can you legally do to protect yourself against
such spying?
After an introductory discussion of how you should think about
making security decisions — it's all about risk management — we'll be
answering those two questions for three types of ..
First, we're going to talk about the threat to the data stored
on your computer posed by searches and seizures by law enforcement, as
well as subpoenas demanding your records.
Second, we're going to talk about the threat to your data on
the wire — that is, your data as it's being transmitted — posed by
wiretapping and other real-time surveillance of your telephone and
Internet communications by law enforcement.
Third, we're going to describe the information about you that
is stored by third parties like your phone company and your Internet
service provider, and how law enforcement officials can get it.
In each of these three sections, we're going to give you
practical advice about how to protect your private data against law
enforcement agents.
