The kernel developers are generally quite good about responding to security problems.

It is a system which works pretty well.

Cox Communications employee William Bryant recently pleaded guilty to information technology sabotage, having caused the loss of computer, telecommunications and emergency 911 services for thousands of Cox's business and residential customers throughout Dallas, Las Vegas, New Orleans and Baton Rouge .

Although services were fully restored, the incident's effect on Cox's reputation has yet to be determined.
