pings or traceroutes and does not respond to communication attempts on

unused TCP/UDP sockets.

Password Security

To enhance password security, you can use these settings:

• Minimum password length - Allows passwords that are 3 to 255 characters

long; also allows spaces in passwords

• Maximum password age - Specified in days. To disable this setting, enter 0.

• Enforce password complexity - Cannot include all or part of a user’s

account name. Passwords must be at least eight characters long. If you

enable Minimum Password Length, passwords can be 8-255 characters

long and must include three of these four categories of characters:

• English uppercase characters (A-Z)

• English lowercase characters (a-z)

• Base 10 digits (0-9)

• Non-alphabetic characters (!, $, #, %, and so on)

• Enforce password history - Cannot reuse the last nine passwords
