What do Dash Cam's have to do with Information Security?

I always tell my family and friends to purchase a dash cam for their vehicles. Because you never know. But what does this have to do with Information Security? 

Quite a lot. 

Having a dash cam can help reconstruct what happened right before and after an accident. Often in accidents and investigations there will be conflicting reports between witnesses. People's memories are often hazy or get distorted as they are recalled more often and as more time passes by. 

In information security, I am advocate of having strong Network Security Monitoring infrastructure in place so that when an incident occurs there is data available that can be used to reconstruct the events. One of the worst feelings in information security is realizing that data is simply not there to answer the critical questions. 

So if you drive, go out there and get a dash cam. They run roughly $100-$200 and can be purchased at an electronics retailer or online.
