It is a good policy to routinely change your password to protect data, even in what you may consider a 'safe' environment. In the workplace, failure to apply an appropriate password policy could leave you in breach of Data Protection laws.
Please consider the following guidelines when selecting a password:
* Ensure that your password is an adequate length; 6 characters should be the absolute minimum number of characters in the password.
* Ensure that your password is not open to dictionary attacks. Use a mixture of upper and lower case letters and numerics, and avoid words or names. Consider using the first letter from each word in a phrase that you will remember easily but is an unfamiliar acronym.
* Ensure that your password is changed regularly; at minimum, change it every ninety days.
The above should be considered a starting point: It is not a comprehensive list and it **will not guarantee security**.
