Protection from Password Cracking
Here are some suggestions on how to keep your passwords from being cracked:
1. Use strong passwords that cannot be determined by a dictionary attack.
2. Don't post your passwords near your computer.
3.Limit wrong attempts to three tries, then lock the account. The
password must then be reset.
(This does not apply to documents or password protected zip files –
they do not have lock out options.)
4.Change passwords regularly.
5. Use a variety of passwords for different computers. Does this mean
that you need to create a unique password for everything? Absolutely
not. Maintain a master password for things that don't matter . But use
good passwords for anything that actually
needs to be secure.
