Access by file type
Before you begin
- This feature requires an Advanced Threat license. To participate, contact your Akamai representative.
- The ETP Proxy must be enabled to use this feature.
ETP allows you to block or monitor specific file types based on MIME type. To detect the MIME-types, ETP inspects the actual HTTP payloads and file extensions. It does not evaluate Content-Type headers which do not always match the actual file types.
Note: ETP does not inspect individual files within archive files, such as ZIP, TAR, and RAR files. To block files within archives, set file blocking on one or more archive file MIME types, such as application/zip, application/x-tar, application/x-rar (see steps below).
This procedure allows you to block or monitor the download of specific file types.
