This is something most do not think about, but it is very important. You should shred important documents. If you have documents that contain sensitive information such as passwords or even a network diagram, you need to shred it. Why, hackers and people up to no good will look at trash and attempt to find information to use to attack you. This could be an easy way to obtain sensitive information. Do not just get a cheap shredder; get one that makes confetti out of the paper.
