Security incident tickets and notifications begin to be sent to customer incident contacts using Fusion platform where actionable behaviors are identified through detection and response processes. Ongoing action as vendors release updates for variants and additional policy updates.
Activity communicated to customers through Fusion cases and change tickets. We immediately investigated the vulnerabilities and potential exploits and continue to monitor the situation as new Log4j vulnerabilities are released.
Where there was potential for abuse via the exploit, we have remedied this in our environments. We are taking a proactive response and actively hunting for the presence of attacks via Log4j.
We are diligently watching over our customers for exposure and associated attacks, as we are able to detect the exploits in the wild. We are taking action with approved mitigation efforts. Trustwave MDR Advanced clients have been advised of the active threat hunt activity that has occurred via Fusion and standard processes. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from malicious servers when message lookup substitution is enabled.

Check the boxes to select the desired conditions. In general, the more boxes selected, the more restrictive the conditions on downloads or uploads. This is the basic condition.
Note: Best practice is to block files that are reported as password protected or corrupt since these cannot be scanned as well as files containing malware.
This Condition invokes one or more TextCensor Scripts to check the text content of a web page or other text file. If you have configured complex scripts, scanning can have an impact on perceived performance. To enhance processing speed, in most cases a TextCensor rule that blocks a request should also add the URL to a category.
To create a new TextCensor Script, click New. To review and edit an existing TextCensor script, select the script name and then click Properties. If you have selected more than one TextCensor Script from the list. Click All to open the Multiple Scripts window.
Choose from the following. Select an option, and then click OK to return to the parent Wizard. This Condition allows you to apply Rules to specific file types. File types are recognized by their internal structure, and not by their name or extension. Caution: Although this condition is available in both Standard and Content Analysis rules, Trustwave recommends you use it only in Content Analysis rules. Standard Rules are often evaluated when only part of the data is available, and for many types this makes determining the type of the file unreliable.
Content Analysis rules are always evaluated once the entire file has been downloaded and the file type has been correctly determined. For more information, see Trustwave Knowledge Base article Q Note: You can match files in two other ways:. Expand any category to see the particular types available. Choose the categories or specific types of files to match. Note: Some types cannot be checked by Standard rules.
The Select File Types window for Standard rules shows these types in the lower pane. You can check for these types in Quota or Content Analysis rules. This Condition allows you to apply Rules to all files that are not of specific file types. See the condition Where the file type is for details on how to select types.
This Condition allows you to create Content Analysis Rules that check a condition for a file that was requested, or all files that are contained within it if it is a document or archive that WebMarshal can unpack. For instance, you can apply a rule to document files that contain images.
For other options, see the condition Where the parent file type is. You can choose to include or exclude the originally requested file from matching. Click is or contains to open the Trigger window. Tip: For example, if you want to make a rule that applies to all image files, including image files within documents or archives, select The transferred file or any unpacked file. If you want to make a rule that applies to image files within documents or archives, but NOT directly requested images, select Any unpacked file.
This Condition allows you to create Content Analysis Rules that apply to a file that was unpacked from an archive or other unpackable type, depending on the type of the parent file. Note: For other file type conditions, see Where the file is or contains a file of type, Where the file type is, and Except where the file type is. You can choose to perform matching on the originally requested file, all unpacked files, or only the immediate parent container.
You can find a specific User or Group by typing a few characters in the bottom text field. Note: WebMarshal supports nested User Groups. WebMarshal protects against virus infection, other malware, and exploits for all downloads and uploads in a number of ways: by TRACEnet filtering, by passing messages to third-party scanners, and by file name and file type rules. WebMarshal can scan for viruses, malware, and other malicious content using the Malware Scan condition in Content Analysis rules.
Before you can enable rules that use this action, you must install and configure at least one scanner. Note: WebMarshal can apply malware scanning to all types of files. Scanning all files provides added assurance but has a significant impact on performance.
These rules can cause users to experience page loading times 2 to 4 times slower than when using standard rules. Other types of rules also help to protect against malware downloads. WebMarshal helps to achieve the goal of conserving network resources by proxy caching, Connection rules, Quota rules, and Content Analysis rules. You can reduce bandwidth usage by enabling WebMarshal proxy caching. Caching is enabled by default on new installations.
You can manage connections from many popular Instant Messaging and Streaming Media applications, as well as the WebSocket protocol. Sample blocking rules are provided in the default configuration. To quickly apply these rules to a user, add the user to the pre-defined WebMarshal Group Restricted Users. Sample quotas are configured in the default rules, but all quota rules are disabled by default.
WebMarshal can stop the download of oversized files by a Standard rule. WebMarshal can also stop uploading of oversized files by a Standard rule. These file size rules are enabled by default for the Restricted Users group. When triggered, these rules take similar actions to the rules described earlier.
