   Table 1 Protection policy parameters

   Parameter	Description	Example Value
   Policy	Policy name	test
   Action	Indicates how an event is handled. Report alarm and isolate Report alarm	Report alarm and isolate
   Bait File	After bait protection is enabled, the system deploys bait files in protected directories and key directories (unless otherwise specified by users). A bait file occupies only a few resources and does not affect your server performance. If ransomware prevention is enabled, this function is enabled by default. NOTE: Currently, Linux servers support dynamic generation and deployment of bait files. Windows servers support only static deployment of bait files.	Enabled
   Bait File Directories	Protected directories (excluding subdirectories). Separate multiple directories with semicolons (;). You can configure up to 20 directories. This parameter is mandatory for Linux servers and optional for Windows servers.	Linux: /etc/lesuo Windows: C:\Test
   Excluded Directory (Optional)	Directories where bait files are not deployed. Separate multiple directories with semicolons (;). You can configure up to 20 excluded directories.	Linux: /test Windows: C:\ProData
   Protected File Type	Types of files to be protected. More than 70 file formats can be protected, including databases, containers, code, certificate keys, and backups. This parameter is mandatory for Linux servers only.	Select all

5. Click Next and select servers. You can search for a server by its name or by filtering.
