Your goal is to make it as difficult as possible to dissuade a hacker from getting your data or from being a victim of cybercrime
Cybercriminals go after easy targets unless the victim has something of great value
№26 слайд
Содержание слайда: Good Line of Defense

Make them work them for it! In doing so, they might give up and move on to an easier target
Minimizes the chances of being a victim
№27 слайд
Содержание слайда: Password Cracking Example
Hackers use “Brute-Force” Password Crackers
One group cracked 2700 “bad” passwords in 30 seconds
The crack program ran for 48 hours more and did not crack the 250 remaining “good” passwords
Do the hackers keep trying to get the remaining 250 passwords? Or do they find easier targets?
Your goal: Be one of the 250
№28 слайд
Содержание слайда: Are you a target?
