To block all FTP connections regardless of the ports being used, the following steps should be taken using Netskope's Cloud Firewall:
* Real-time Protection Policy:
* Create a Real-time Protection policy where FTP is defined as the destination application.
* Set the action to "Block" to ensure that any FTP traffic is blocked regardless of the port being used.
* Custom Firewall App Definition:
* Create a custom Firewall App Definition specifically for TCP port 21.
* Define the action as "Block" to ensure any traffic directed to this port is blocked, preventing FTP access.
These configurations ensure that FTP traffic is effectively blocked, securing the network from potential threats and unauthorized data transfers via FTP.
