How to effectively control outgoing files, block USB and prohibit outgoing files through the network.

1. The first thing is to block the computer's usb storage devices.

You need to disable configuration in the group policy of windows computers. Change "disable installation of removable devices" to "enabled". Of course, administrator privileges cannot be given to users, otherwise changing the policy back will not work.

two。 Block all kinds of file transfers in application filtering

3. Configure the policy by applying filtering to allow only corporate mailboxes

Ban all kinds of mail protocols first.

Add the company's mail server to the exception setting so that employees can only send mail through the company's mail server.

4. Block all kinds of network disks and file transfer websites

Then through the "web filtering" module, the "mail", "network disk and file sharing" and other categories are blocked.

Of course, in order to achieve stricter control, it is safer to use the "website whitelist", which only allows you to visit work-related websites.

After the above configuration, you can effectively control the outgoing files. Of course, outgoing files can also be controlled by means of file encryption, cloud desktops and so on. I will not dwell on other ways.
