Some interesting information on passwords

The other day I was reading a pretty neat article on Business Week that had some interesting information on passwords.

Ah passwords. So difficult to remember, so easy to guess. This chart below is taken from the article which gives you rough estimates on how long it would take to crack.

As a worker in IT, passwords means one thing: Change them often.

Most-used passwords: 123456, password, 12345678, qwerty, abc123

Time it takes a hacker’s computer to randomly guess your password:

Length: 6 characters
Lowercase: 10 minutes
+ Uppercase: 10 hours
+ Nos. & Symbols: 18 days

Length: 7 characters
Lowercase: 4 hours
+ Uppercase: 23 days
+ Nos. & Symbols: 4 years

Length: 8 characters
Lowercase: 4 days
+ Uppercase: 3 years
+ Nos. & Symbols: 463 years

Length: 9 characters
Lowercase: 4 months
+ Uppercase: 178 years
+ Nos. & Symbols: 44,530 years

Average amount it costs a business to field a phone call requesting a password reset: $10
Proportion of help desk calls that are password-related: 30%
Users who choose a common word or simple key combination for a password: 50%
