Network Server
Security settings designed for a machine providing network services such as a web
server, file server, name server, etc. This set provides the most secure configuration
of the predefined settings.
Custom Settings
A pre-selected Custom Settings (when opening the Predefined Security Configura-
tions dialog) indicates that one of the predefined sets has been modified. Actively
choosing this option does not change the current configuration - you will have to
change it using the Security Overview.
8.3 Password Settings
Passwords that are easy to guess are a major security issue. The Password Settings dialog
provides the means to ensure that only secure passwords can be used.
Check New Passwords
By activating this option, a warning will be issued if new passwords appear in a
dictionary, or if they are proper names (proper nouns).
Test for Complicated Passwords
When this option is checked, any new password is checked that it consists of a
mixture of characters, digits and special characters. If it fails to pass this test, a
warning is issued upon the entering of the new password.
Number of Passwords to Remember
When password expiration is activated, this setting stores the given number of a
user's previous passwords, preventing their reuse.
Password Encryption Method
Choose a password encryption algorithm. Normally there is no need to change the
default (Blowfish).
Minimum Acceptable Password Length
If the user chooses a password with a length shorter than specified here, a warning
will be issued.
