Network engineers are technology experts not security experts. They often need training to raise their awareness of security issues. Remember the study a while back that found that the largest single factor that caused network failures was human error? > > The only way to protect against that sort of situation is to > > encourage everyone to be security-minded and not take risks > > where the network is concerned. > > Definitely.

The question in that case is: "Do you know, in enough detail, what is going on in your network that you can confidently say that nothing awful is happening?". --Michael Dillon
