so im not too smart when it comes to security. i just pretty much know the basics. im on a windows machine so i have norton, and then a password on my router to access my wireless network. ive been reading a lot about phishing, and VPN (i think thats what it was, i cant really remember) and i just read about mobile me and the web app using SSL. which i have no clue what it is. and some guy was talking about DNS forgery attacks.. so obvoiusly im a complete noob when it comes to stuff like this, but i really would like to learn more about it. so i guess my question is, what are these things: VPN, SSL, and DNS. and maybe some other things lol. i guess i just want to know that what im doing on my computers in my house arent being seen by other people, like when im shopping online using credit card information etc. and nobody can get into my wireless home network.
