You contact the SmartView Tracker about ftp connections to a ftp server called boson that keep dropping after an two hours of idleness. The SmartView Tracker shows “Unknown established error” entry for this connection. How would you resolve this error without causing any other security problems?

You will create a new TCP service object on port 21 which you can name as ftpboson, then configure the Global Properties. You will then use the new object only in the rule that allows the ftp connections to the boson

B.
Go to the Global Properties window, increase the ftp connections to 24 hours

C.
You will create a new TCP service object on port 21 which you can name as ftpboson. You will then use the new object only in the rule that allows the ftp connections to the boson
