Blocking executable file uploads

To block the upload of executable files, click Advanced Options. Under Executable File Uploads, select Block executable file uploads. This setting blocks the upload of all executable files across your organization.

You can enable analysis of inbound executables on the Web Content & Security tab. See Configuring file analysis. To block the download of executable files, see Blocking by file type.


	Important Executable files included in archived/compressed files are not blocked. Archived/compressed files are inspected for malware but are not extracted to determine if the contents contain an executable file that should be blocked. Archived and compressed files can be blocked, if needed, to avoid uploading an unwanted executable file.

Block file downloads based on size, or size and category

To limit the download of all files based on file size, or size and category, click Advanced Options. Then:

Under File Size Limits, set the file blocking Rule State to Enabled.

To configure blocking by file size for all categories:

Under Blocking Options, select Block all files over... KB.

Specify the size limit (1000 KB, by default).

To block files in specific categories:

Select Category specific blocking.

Fill in the size in kilobytes. Files over this size in the categories you choose will be blocked.

You can select a category directly from the list, or enter text in the search box to locate the category you want. Click on the plus sign to the left of each category to view subcategories to which you can also apply blocking actions.

To select multiple categories, use the Shift and/or Ctrl keys. You can also use the drop-down menu above the category list to select Web 2.0 categories or privacy categories, or to select or deselect all categories.

Optionally, enter or select the users and groups to whom the file blocking applies. You can also specify that the file blocking applies to all users and groups in the policy except the group you select.

Select the block page that will be displayed when this file size is detected and blocked.

When you are finished making changes, click Save.
