Ive been reading alot of stuff on here and have two books im reading on hacking and security measures. My question is this. In order to use, port scanners, scanners , sniffers and other tools. Do i need to have a knowledge of programming to use the tools or do they tell you how to use them. So far I have come across nothing that explains wether i need to have programming knowledge in order to use the tools and understand the info they are sending. Appreciate any assistance.
