Default Likelihood of IT using a Packet Sniffer

A buddy of mine used to have a PC that didn't work through his
employer's network but tapped straight into the internet (not sure how
that setup worked, so just bear with me). Recently, they moved from a
wired network to a wireless one. To our knowledge, that machine is
still set up with a direct connection (he uses an external computer
system and it doesn't work well with the netowork).

A mutual friend of ours happened to mention the concept of a packet
sniffer to him and now he's completely paranoid about using said PC
for anything other than the strictest of business. A day gets boring,
so you hit a few of your gaming forums, browse a bunch of news sites,
and maybe doing some instant messaging (GMail ftw!), whatever. No,
he's not hitting porn; he's bored, not a moron!

I've tried explaining to him that the only reason they're going to be
checking his traffic is if he's given them a reason to do so. He
busts his ass for the company, is almost always on time, works OT at
the drop of a hat, and is basically his boss's right hand man. Even
so, he won't so much as crack open his GMail now to check it during
the day out of fear of Big Brother watching.

So I ask: How likely is it that his IT department is bothering to sit
down and piece together his IM threads to find out about us talking
about Dr. Who's season finale? Sure they COULD do that, but does any
IT group turn that kind of stuff on by default, or is it only a "Yeah,
this is Jones up in Finance. I want to keep track of Larry
Riley...can you see what he's doing online?"

It varies from "almost certain because they're logging IM traffic
automagically and proxying it to the internet" to more along the lines
of what you're suggesting--auditing on an as needed basis if he's
screwing up in something else. Depends on teh size of the
organization, their risk tolerance, and IT infrastructure.

It also depends on what he signed in terms of paperwork when he was
hired.

I will share this though:

I know of a guy who worked for a large retail chain's front end
development staff. He had exchanged ongoing jocular banter between
him and a colleague that had a high incidence of Jerky Boys quotes.

It came to management's attention some how and they were both fired
for it. I don't have the entire story, so take that for what it's
worth, but there's reason to be extremely cautious with this.

Personally though, if my employer won't treat me like an adult and
allow me casual and resonable access to a personal email account
during the day, I don't wanna work for them.

If you want to keep them from being able to read your personal email,
that's where encryption and proxies come in.

We documented a case of a worker sending 843 emails in one shift, they
were warned 3 times and then fired. Most of the employees at our
customers have little need for outside email, so it's easy to monitor.

We can run a report in seconds that shows User, date, subject, number of
emails per subject, number of emails per day, total emails per period,
in/out direction, who to/from....

We normally check for 30 external emails per week or more for people
that have no business using external email addresses, above that and
they are warned/fired.

With this and web filtering/monitoring, most places see an increase in
productivity, as high as 30% after the first couple weeks of enacting
the policy.

Who owns the computer? You? Or your employer?

If it's not your computer, then you have no right to dictate how
it's to be used.

Where do people like you get the idea that you have a _right_ to
use the company computer they way _you_ want to?

I fully agree, but that's not the point.

Todd said "if my employer won't treat me like an adult and allow me
casual and reasonable access to a personal email account during the
day, I don't wanna work for them"

That's a fair statement to make, as long as it is made openly. One
doesn't *have to* work for a certain company, and a certain company
doesn't *have to* hire him. It takes two to tango.

Point taken.

It's just that I see so much on TV, etc... of people whining when
they get in trouble for doing personal stuff on the company
computer, as if it was their God given right that was just tread
upon.

But I have to wonder, would a person not take or quit a job just
because they can't have access to their personal email from the
work computer?

On a related tangent, it just seems to me that too many people
don't respect other's property.

Sounds like your friend has a job he's doing well at it. Why don't
you find something else to amuse yourself other than risking his job
by chatting with him while he's at work?

Well, it certainly isn't a god-given right, but you keep your employees
happy (and thus more productive) if you allow them to stray every once
in a while. Provided they get their work done, that is.

Yup.

For anyone that's worked in such a draconian environment, a fascist
policy and technical controls that prohibits an employee accessing
some personal email during the day tend to be just one symptom of a
much larger trust problem.

For many tech workers, it'd be akin to prohibiting a personal cell
phone on the premises, or having a strict prohibition against the
taking of any personal calls on the work phone line.

That's not to say there aren't job roles where such prohibitions are
required, or tend to attract workers that wouldn't get their **** done
otherwise. My work, however isn't in such space.

In Belgium, if the IT department wants to check up on you, they are
obliged by law (CAO nr. 81) to inform the employee(s) about this
/before/ they start checking up on him/her/them. Not informing them is
considered illegal and an invasion of privacy.

Of course, the IT department is permitted to collect anonymous data. For
example, they can screen which sort of attachments are being
sent/received or look at which URLs are being accessed, as long as this
is done "global" and not on a personal level.

So, you might want to check what the law in your country says before
asking such questions in an international newsgroup...

We fire people for personal use of company networks, they understand and
don't use it.

And for many companies, it's not a trust issue, it's a COST issue. We've
documented many cases where about 3% of the workers waste real hours per
day doing "Personal" internet things instead of working.

You're right about it being a symptom, it's a symptom of how few ethics
some people have, how people have adopted the mindset that the Company
OWES THEM A JOB.....

When you're at work, work.

We use GFI Mail Essentials at most locations, great product for
monitoring emails. We also log all emails (full contents) for medical
clients.

Hence it is a privilege, not a right.

Don't get me wrong. I'm not saying employers should be that
strict. What I am saying is that employees need to understand
their place in such a situation.

Yes, I browse at work. I try to restrict it to my lunch time,
and try to restrict where I am going. I never do personal chat
or email of any kind. Typically, it's just catching the news
or browsing wikipedia or the like.

I simply respect the trust my employers have in me and I don't
abuse it.

Did you also take into consideration the possible loss of productivity
caused by unmotivated workers?

Not everything that's countable counts and not everything that counts
is countable.

BS. It's just about the straight line between job and private life
loosening up.

Ethics is a subjective matter which changes over time.

Okay. So when at home I accidentally get to think of my job or maybe
come to think of a good idea that's job related I can claim an extra
pay for that or take a day off.

A good rule of thumb is: Don't do anything you wouldn't want your boss

In many companies real hours are "lost" from smokers going to the
smoking area for a break. It's a cost / benefit issue.
