Talk
on Tech
Welcome to the
newest feature of the St. Charles School District website. Talk on Tech will
feature monthly updates on using and understanding the technology
available within the district. Enjoy!
Spam
Already You are the
Winner Most Lucky!
I remember being ten years old, stalking the mailman each summer
day. I was hoping for a letter back from Jenny, the girl from
Pennsylvania I met on the family vacation to Orlando. I didn't mind
the long, hot hours spent staking out the front yard. I got excited
when the mail truck appeared at the top of Longford Drive. Maybe
today would bring word from the woman that, with a committed
courtship and a long campaign of letter-writing, I hoped to someday
divorce.
For the most part, that kind of correspondence is a thing of the
past. Because of today's technology, when we want to stay in touch
with family, complain to businesses, or talk to girls we met in
Florida, we can communicate instantaneously. Email is so prevalent
that it's tough to find someone who doesn't have it. Electronic
communication has truly made the world a smaller place.
And then, there are the spammers, who set up automated systems for
inundating your email box with unwanted, sometimes offensive
material. In this, the first of a series of columns detailing
technology use and safety in the St. Charles School District, well
discuss who the spammers are, and what your tech team is doing to
stop them.
What they do, and why they do it
In the old days of paper junk mail, senders had significant postage
and material costs between them and your mailbox. Today, setting up
an email server is relatively cheap and easy. And because it's a
machine, it doesn't balk about working 24 hours a day to let you and
every other carbon based life form know that you have, in fact,
already won.
Won what? It doesn't matter. Maybe a boat. Maybe access to drugs
without prescriptions. Want whiter teeth? Just click the link. Bill
Gates is dying to give you a big chunk of his fortune, if only
you'll tell ten friends to get some, too. The good luck never seems
to stop raining on your inbox. Why, people from Africa have heard
about you. If you haven't already, you should soon be getting a
letter from the son of a prominent and wealthy African, who
wants for reasons that aren't really clear to send you millions of
dollars. He'll just need your bank account info.
Does anybody really fall for this stuff? A small percentage of
people really do. But as
this excellent article by the University of
Oregon's Dr. Joseph St. Sauver points out, spammers don't even count
on you buying that discount Viagra they're hawking. Junk e-mailers
can generate profits without selling a thing. If you click on their
links, or even the unsubscribe option, spammers count you as a
visitor to their websites. They then use this artificially inflated
traffic to sell ad space to other companies.
The result? Spammers make money for doing nothing more than annoying
you. In this regard, they are not unlike television comedian Bob
Saget, formerly of Americas Funniest Home Videos infamy.
What were doing about spam
On the topic of junk emails, picture your district technology staff
like a vanguard of knights in shining armor, guarding the gates of
our technological kingdom against gnats. We have many intimidating
security systems in place, but the reality is that there are so many
spammers spamming away out there that some sneak through.
Our first line of defense is a new technology we implemented over
the summer. MOREnet, our Internet service provider, has worked with
us and other districts to block spam before it ever approaches our
private network. The program isn't completely successful, but we do
estimate that it has reduced junk mail by about 80 percent.
We also have a nifty device called a proxy server, which acts as the
gatekeeper for all traffic in and out of the district. We've tweaked
that server to be aware of the worst spammers, and taken
countermeasures against them. Finally, we have anti-virus software
that knocks down spam traffic generated by a virus type called a
worm, which sneaks into your address book and sends bulk mail
without you even realizing it.
Our final defense is manually tracking and blocking individual
spammers, when new ones happen across our network like ants
stumbling across a picnic. We can go in and block emails from
certain addresses from ever appearing in your mailbox. However,
there are problems with this last approach. The main one being that
spammers - like gnats - multiply and swarm pretty fast. Once they elude
our electronic bug zappers, swatting them can be more than a full
time job.
Canning the spam
Want to help us swat gnats? Be careful who gets your email address.
Don't sign up for free offers! online. When you do get spam, never
hit the unsubscribe option - often, that leads to more spam, not less.
These folks aren't known for their ethics.
Finally, the biggest thing you can do to help is find and get
friendly with the delete key. Until there are real, enforceable laws
against unsolicited mass mailings (check here for developments in
that area), spam is going to be a fact of life. When that next ad
arrives promising you leaner abs, more endurance, African riches or
a good deal on an illegally smuggled panda, pretend it is screaming
when your index finger sends it off to oblivion. Meanwhile, well
keep swatting as many gnats as we can.
And if anybody hears from Jenny from Pennsylvania, tell her I never
got her letter and give her my email address.
