Opps, they did it again…

27. June 2008 by admin.

I just read an article about another 51,000 credit card numbers going into the wind… See the article here…

These stories scare the bejeebies out of me… I guess it’s a “there, but for the grace of  God, go I” kind of thing.  How would I know if someone has my credit card information?  Apparently the company that bought the rights to the Montgomery Ward name didn’t feel it was important enough to let their unlucky customers know.

I wonder if someone has any of my financial information.  I am pretty sure there is no key-logger installed on any of my own computers…make that 99.999% sure, but not 100% sure.

Since I constantly work with other people’s data, I am especially sensitive to the possibilities and careful to stay as infection-free as humanly possible.  But since I am human, I can’t be 100% certain… No one can. Firewalls, anti-virus, anti-spyware, and Trojan remover software…all of these things stand guard between me and thee, but is it enough?  Who knows?

As we move out from my semi-controlled environment and into the technological wilderness of my client’s accounts, I become more and more concerned.

At my Wilmington Delaware network support company, we always spend extra time stressing to our clients just how important safe surfing and safe-email practices can be.  We spin a lot of  “what if” tales to illustrate just what can happen if you let your guard down for even a minute.

We’ll take a computer with a new, unpatched installation of XP and set it in the client’s DMZ, then check it a couple of hours later. Almost every time you’ll find that the available free drive space has shrunk by 2 to 3 gigs. This is  a great argument for when a client thinks they are too small to be of interest to a hacker. There just “ain’t no such animal” as an installation that is of no interest to a hacker.

We monitor our clients’ anti-malware installations and make sure the signature files get updated daily. We check the status of the firmware of the hardware firewalls daily. We make sure that all available patches are up-to-date (after checking them for unexpected results).  We run Snort intrusion detection on our larger clients.  We train.  We explain. We do pen testing.  And still, I worry if some client is giving away the keys to the kingdom… right now.. this very minute.
