What's new in 4.11.2?

The following new features and enhancements are contained in the 4.11.2 version of the Gateway. This includes updates since the release of version 4.10.0.

Upgrade components for 5.0.0

The 4.11.2 release provides the tools to enable an in-place upgrade of your Gateway 4.x software to Gateway 5.0.

Sanitize URLs in documents

You can now use a Sanitize Document Content rule to detect and remove potentially harmful URLs from documents. See URL Lists to find out more about configuring lists of URLs as policy references. You can also find out more about adding URLs and Hyperlinks to a content rule in What To Look For? Clauses.

Images extracted from PDFs

You can configure the Gateway to extract and scan images from PDFs. This feature is not enabled by default on the ICAP Gateway. To enable PDF image extraction, see Setting Processing Limits.

OCR for Web

The OCR (Optical Character Recognition) feature scans and reads text that might be displayed in images. This allows the Web Gateway to detect, and consequently block or redact any suspicious or confidential text it discovers. OCR is available on three content rules: Check Registered Data, Detect Lexical Expression, and Redact Text. See Content rule templates for more information.

Improved searchability in reference lists

You can now use the Search text box at the top of a list to search for a particular entry within a list. This has been applied to the following sections: Machine Lists, User Name Lists, Internet Zones, and Intranet Sites.

Configurable transaction logs

You can now select which fields are included in the Web Transaction log, using the ICAP Settings > Transaction Logging page. The Fields area enables you to configure the Current list of fields that will be generated. See Configuring Transaction Logging for more information.

Sanitize and redact metadata in GIF and PNG image types

The GIF and PNG image types are now supported by the following sanitization-related and redaction-related content rules: Analyze Properties, Detect Lexical Expression, Redact Text, Sanitize Document Content. Metadata found in these image types can be sanitized and/or redacted based on how these content rules are used in your policy. See Sanitization and Adaptive redaction to find out more about supported media types.

Detect RAR5 archive files

You can now detect RAR5 archive files and inspect the contents. If your existing content rules have this clause set to Include all media types, RAR5 will be automatically detected from now on. If your rules do not have Include all media types enabled, RAR5 is included within the RAR - RAR compressed Archive type. For more information on the Which Media Type clause, refer to What To Look For? Clauses.
