Public Notification of a Hack
By Rick Johnson

We've all been there before.  You work all night assessing the damage 
on a compromised server, and compiling a report showing known 
compromised areas and those potentially compromised. The internal 
emergency work is done, but now it's time to deal with the public.  How 
do you proceed?  Advice on dealing with the technical side effects of a 
compromise can be found relatively easily, but very little information 
exists dealing with the after effects of a malicious hacker ruining 
your day. 

Most companies prefer to suppress any information about a compromise 
and with good reason.  Such bad publicity can erode confidence, cause a 
revenue drop, and, worse yet, send investors running the stock price 
plummeting. Clearly it's touchy issue.

Sure, the whole incident could pass with little more than a whisper if 
you decide to keep things quiet (and succeed). Should word leak out 
though, you have made it worse.  So before deciding whether or not to 
publicize a compromise, perform an external damage assessment and 
consider the following issues.

Was any customer data affected?
If the answer is yes, then the company must notify its customers 
immediately -- especially when credit card information is leaked to the 
world. Notifying customers can be done in a variety of ways. Personal 
contact is always preferable, but rarely a viable option.  Emailing the 
affected customer base should be your second choice. Also be prepared 
to continually update customers as the situation changes.  Finally, the 
least favorable option would be issuing a wide scale press release.  
Certainly not the best choice, but it's still better than customers 
hearing about it on CNN.

What would be gained by exposing the compromise?
Exposing the incident can reduce the damage by allowing your public 
relations department to spin the release far more favorably than your 
average news report. Exposure also shows you have nothing to hide and 
that the compromise was just a case of bad luck.  Now you can show how 
diligently your staff has worked to correct the vulnerability and 
prevent it from happening again.

Keep everyone in the loop
Before making any public statements, consult with your Legal 
department.  If you do not have one, then contact an attorney skilled 
in these matters.  Legal should approve any prepared statements or 
press releases before reaching the public domain.  Of course, make sure 
your technology department has patched every hole before releasing any 
information. Once the proper action has been decided, inform the entire 
organization of the procedures for handling the incident. Even in cases 
where customer information remains safe, you should be ready to discuss 
the security problems publicly.

Prepare to be the scapegoat
Drastic enough situations could result in someone being fired. An 
individual's mistake occasionally results in a compromise, but more 
commonly companies terminate an employee to show stockholders and 
customers that the weakest link has been removed. We all know who gets 
blamed first and if it was your fault, then start typing your resume. 
More often, an executive did not heed your warnings, which resulted in 
a compromise.  Cover yourself by documenting every recommendation and 
the response when presented. Once someone disregards your warning, they 
then take responsibility if the worst should happen.
