Security
The Security screen controls access to the CN9000/CN9600/CN9900/CN9950
and allows you configure the login failure policies, filter settings, encryption
settings, security level, working mode, private certificate and certificate
signing request.
Login Failures
For increased security, the Login Failures section allows administrators to set
policies governing what happens when a user fails to log in successfully.
The meanings of the entries are explained below.
Login Fail Policy: Select the login failure policy that the CN9000/
CN9600/CN9900/CN9950 applies.
Lock Client PC – If this is enabled, after the allowed number of failures
have been exceeded, the computer attempting to log in is automatically
locked out. No logins from that computer will be accepted. The default is
unchecked. This function relates to the client computer's IP. If the IP is
changed, the computer will no longer be locked out.
Lock Account – If this is enabled, after the allowed number of failures
have been exceeded, the user attempting to log in is automatically locked
out. No logins from the username and password that have failed will be
accepted. The default is unchecked.
Allowed – Sets the number of consecutive failed login attempts that are
permitted from a remote computer. The default is 5 times.
Timeout – Sets the amount of time (in minutes) that a remote computer
must wait before attempting to login again after it has exceeded the
number of allowed failures. The default is 3 minutes.
Note: If Login Failures is not enabled, users can attempt to log in an
unlimited number of times with no restrictions. For security purposes,
we recommend that you enable this function and enable the lockout
policies.
