Is Privacy a Thing of the Past?
by Rick Johnson

If you have seen the news this week, then the FBI's latest tool should 
have you afraid to use the Internet. If you have not yet heard, here you 
go.

The FBI system, dubbed Carnivore 
(http://www.fbi.gov/programs/carnivore/carnivore.htm), connects directly 
to an Internet Service Provider's network and has the potential to 
monitor all of the communications traveling through the network. It 
snoops e-mails, officials announced Friday. The FBI claims it will use 
the system only with valid court orders and that Carnivore will allow it 
to narrowly target its investigations. Of course, the system has to 
review all traffic to decide what is logged. Anyone see a problem with 
this?

Through the Freedom of Information Act, the American Civil Liberties 
Union is trying to force the FBI to disclose details of the inner 
workings of its Carnivore system (http://www.idg.net/go.cgi?id=42853). 
"The FBI takes the position of, 'Trust us, we're the government. Open 
your entire network to us,'" says Barry Steinhardt, associate director 
for the American Civil Liberties Union, which sent a letter about 
Carnivore to members of Congress. "There's no way for an ISP to know 
what they're doing."

The FBI refuses to reveal the inner workings or the Carnivore system to 
anyone. Due to the security concerns this presents, most ISP's are 
vowing to fight against any court order forcing the implementation of a 
Carnivore system. Having cut my teeth in this environment, I can tell 
you that an ISP is more than capable of complying with a court order and 
gathering any needed information. In the past, the FBI has been 
tremendous help in bringing to justice those who make the Internet 
unsafe. However, violating the privacy of many to convict one is not 
acceptable. I am by no means a paranoid conspiracy freak or 
anti-government activist. I am simply a concerned security 
administrator. I don't care whether it is a 14-year old script kiddie or 
a 92 year old government agency, if I'm not breaking the law, no one 
should have the capabilities to listen in on all traffic passing to and 
from my network.

So, what does this have to do with Linux Security you ask? It's the most 
basic form of security -- privacy. You can lock down your servers but 
what good is it if the data leaving them is used against you? Sure, 
there are ways to encrypt standard services such as Web, mail, and FTP; 
however, they still maintain the ability to track where you visit and 
with who, you communicate. Of course, the general mentality is, "If you 
aren't committing a crime then you have nothing to worry about." How do 
you argue with that kind of logic? Remember, Big Brother is not just a 
TV show.

Ok, so occasionally I like to play the role of the paranoid security 
freak. Can you blame me?
