<strong>Polycom</strong> <strong>RMX</strong> <strong>2000</strong>/4000 Administrator’s <strong>Guide</strong><br />

An administrator can assign a new password to a user at any time.<br />

Forcing Password Change<br />

When the system is in Enhanced Security Mode the user is forced to change<br />

his/her password as follows:<br />

• After modifying the value of the JITC_MODE System Flag to YES, all<br />

<strong>RMX</strong> users are forced to change their Login passwords.<br />

• When an administrator creates a new user, the user is forced to<br />

change his/her password on first Login.<br />

• If an administrator changes a users User ID name, that user is forced<br />

to change his/her password on his/her next Login.<br />

• If a user logs in using his/her old or default password, the Login<br />

attempt will fail. An error, User must change password, is displayed.<br />

• Changes made by the administrator to any of the Strong Password<br />

enforcement System Flags render users’ passwords invalid.<br />

Example: A user is logged in with a fifteen character password. The<br />

administrator changes the value of the MIN_PASSWORD_LENGTH<br />

System Flag to 20.<br />

The next time the user tries to log in, he/she is forced to change his/her<br />

password to meet the updated Strong Password requirements.<br />

Temporary User Lockout<br />

When the JITC_MODE System Flag is set to YES, Temporary User Lockout<br />

is implemented as a defense against Denial of Service Attacks or Brutal<br />

Attacks. Such attacks usually take the form of automated rapid Login<br />

attempts with the aim of gaining access to or rendering the target system<br />

(any network entity) unable to respond to users.<br />

If a user tries to log in to the system and the Login is unsuccessful, the<br />

user’s next Login attempt only receives a response from the <strong>RMX</strong> after 4<br />

seconds.<br />

User Lockout<br />

User Lockout can be enabled to lock a user out of the system after three<br />

consecutive Login failures with same User Name. The user is disabled and<br />

only the administrator can enable the user within the system. User<br />

Lockout is enabled when the USER_LOCKOUT System Flag is set to YES.<br />
