Enabling A Whitelist And Adding Ip Addresses - Polycom RealPresence Group 550 Administrator's Manual

Administrator's Guide for the Polycom RealPresence Group Series
● Admin Settings > Security > Local Accounts > Account Lockout > Lock Admin Account after
Failed Logins is set to 4.
● Admin Settings > Security > Local Accounts > Account Lockout > Admin Account Lock
Duration is set to 1 Minute.
● Admin Settings > Security > Local Accounts > Account Lockout > Reset Admin Account Lock
After is set to 1 Hour.
Scenario 1 - Admin account locked due to excessive failed logins
A user fails to log in to the Admin account twice on the web interface, and the same or another user fails to
log in to the Admin account on the local interface. This means that three failed attempts have been made
to the Admin account so far. If the next attempt to log in to the Admin account on any login port is
unsuccessful, which would mean 4 failed logins, further attempts to access the Admin account are locked
out for 1 Minute (the expiration of the Admin Account Lock Duration period). After the 1 Minute account
lock duration has past, logins will once again be allowed. As this example illustrates, the failed login attempts
made to an account accumulate across any login port.
Scenario 2 - Successful login resets the failed login attempts counter
A user fails to log in to the Admin account twice on the web interface, and the same or another user fails to
log in to the Admin account on the local interface. This means that three failed attempts have been made
to the Admin account so far. If the next login attempt is successful, then the failed login attempts counter
for the Admin account is reset to zero and now once again 4 failed attempts can be made before the Admin
account would be locked.
Scenario 3 - Failed attempts counter resets after failed login window closes
A user fails to log in to the Admin account twice on the web interface, and the same or another user fails to
log in to the Admin account on the local interface. This means that three failed attempts have been made
to the Admin account so far. If no more failed attempts are made within 1 Hour of the first failed attempt
(which is the value of the Reset Admin Account Lock Counter After setting), the failed login attempts
counter for the Admin account is reset to zero, and 4 failed attempts are allowed again before the Admin
account is locked.

Enabling a Whitelist and Adding IP Addresses

When a whitelist is enabled, the Polycom RealPresence Group system web interface and SNMP ports
accept connections only from specified IP addresses. This feature, which supports both IPv4 and IPv6
addresses, can only be configured in the web interface.
In environments where dynamic address assignment is used, ensure that you keep the Whitelist up to
date with the latest assigned addresses for computers authorized to access the system. Failing to
update the Whitelist means these computers cannot connect to the system.
To enable a whitelist:
1 In the web interface, go to Admin Settings > Security > Global Security > Access.
2 Select Enable Whitelist and select Save.
To add addresses to an enabled whitelist:
1 Select Edit Whitelist.
