was curious on password security...lets say the average password on an email server or web site, how can you make the most secure password (tips that is)

basically I was curious cause my friend has a friend that is a "cracker" not a hacker (by term of course) and has hacked into my stuff to "check" on things while i was friends with my friend (we're not now)...but i was wanting to figure a way to make a more secure password and how long it would take for a good cracker/hacker to find out the password (and how they find out)

I was asking, because I want to start hacking my own computer to find out where my computer security lacks, and learn how to build a firewall and other security programs to help protect my computer (through practice of course)

Also i would like to add if you want to get a overview of how hackers operate and how to stop them for beginners i would recommend reading Hacking for dummies.It will help you understand computer security basics without getting over technical. Good luck on securing youre system

just like slinjim100 said,

peace.

Yes teaching paraphrases is a key to strong passwords in the work place. If part of my job is to help implement good security policies at a business, I always teach paraphrasing.
