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