b_64_decode_depth

Specifies the maximum number of bytes to extract and decode from each Base64 encoded MIME email attachment. You can specify an integer less than 65535, or specify 0 to disable decoding. Specify -1 to place no limit on the number of bytes to decode.

You can enable rule 141:4 to generate events for this parameter, and in an inline deployment, drop offending packets when decoding fails (due to incorrect encoding or corrupted data).

Type: integer

Valid range: -1 to 65535

Default value: -1

bitenc_decode_depth

Specifies the maximum number of bytes to extract from each non-encoded MIME email attachment. You can specify an integer less than 65535, or specify 0 to disable the extraction of the non-encoded MIME attachment. Specify -1 to place no limit on the number of bytes to extract. These attachment types include 7-bit, 8-bit, binary, and various multipart content types such as plain text, JPEG and PNG images, and MP4 files.

Type: integer

Valid range: -1 to 65535

Default value: -1

decompress_pdf

Specifies whether to decompress application/pdf (PDF) files in MIME attachments.

You can enable rule 141:8 to generate events for this parameter, and in an inline deployment, drop offending packets.

Type: boolean

Valid values: true, false

Default value: false

decompress_swf

Specifies whether to decompress application/vnd.adobe.flash-movie (SWF) files in MIME attachments.

You can enable rule 141:8 to generate events for this parameter, and in an inline deployment, drop offending packets.

Type: integer

Valid values: true, false

Default value: false

decompress_vba

Specifies whether to decompress Microsoft Office Visual Basic for Applications macro files in MIME attachments.

Type: boolean

Valid values: true, false

Default value: false

decompress_zip

Specifies whether to decompress application/zip (ZIP) files in MIME attachments.

You can enable rule 141:8 to generate events for this parameter, and in an inline deployment, drop offending packets.

Type: boolean

Valid values: true, false

Default value: false

qp_decode_depth

Specifies the maximum number of bytes to extract and decode from each quoted-printable (QP) encoded MIME email attachment. You can specify an integer less than 65535, or specify 0 to disable decoding. Specify -1 to place no limit on the number of bytes to decode.

You can enable rule 141:5 to generate events for this parameter, and in an inline deployment, drop offending packets when decoding fails (due to incorrect encoding or corrupted data).

Type: integer

Valid range: -1 to 65535

Default value: -1

uu_decode_depth

Specifies the maximum number of bytes to extract and decode from each Unix-to-Unix encoded (uuencoded) MIME email attachment. You can specify an integer less than 65535, or specify 0 to disable decoding. Specify -1 to place no limit on the number of bytes to decode.

You can enable rule 141:7 to generate events for this parameter, and in an inline deployment, drop offending packets when decoding fails (due to incorrect encoding or corrupted data).

Type: integer

Valid range: -1 to 65535

Default value: -1

Enable the imap inspector rules to generate events and, in an inline deployment, drop offending packets.

vba_data

Sets the detection cursor to the Microsoft Office Visual Basic for Applications macros buffer.

Syntax: vba_data;
