密码安全 for 教职员工
Passwords need to be complex enough to discourage guessing but easy enough for you
要记住. As computer processors become faster and faster hackers are taking advantage
of better password cracking systems. This means we have to shift the way we generate
密码.
It is best to start using a 12-20 character password or, better yet, a passphrase
to prevent someone from easily guessing it. Really good passphrases should contain
a number of character types, letters, numbers, and special 字符. 保持他们的创造力
and unique to yourself. A passphrase combined with your own "Rules" for substitutions
and character insertion makes them easier for you 要记住 but much harder for
anyone or any computer to guess.
Here are a couple of passphrase generation ideas. If you really like cookies, use
Snickerdoodles, Coconut Macaroons, Gingerbread or Vanillekipferl as a base. 使用一个
special character as a space. Substitute letters with numbers that look the same.
Substitute "o" with the digit zero, "L" with the digit one, "S" with the digit five,
等. Make a phrase out of it, and mix in special 字符. "Snick3Rd00dle$#r#good”.
Mix up your schemes, one year use Cookies, then next year Baseball teams, wood working
tools, maybe Civil War Generals. The advantage of better passphrases is that you can
use them longer before having to change them.
