Potentially malicious file types, customer experience

When setting up a content management policy make sure you add a list of file types you want to be set on hold to prevent them from harming your system  Here is the list of potentially malicious file types. There are four main sections:    Programs    .EXE – An executable program file. Most of the applications running on Windows are .exe files.  .PIF – A program information file for MS-DOS programs. While .PIF files aren’t supposed to contain executable code, Windows will treat .PIFs the same as .EXE files if they contain executable code.  .APPLICATION – An application installer deployed with Microsoft’s ClickOnce technology.  .GADGET – A gadget file for the Windows desktop gadget technology introduced in Windows Vista.  .MSI – A Microsoft installer file. These install other applications on your computer, although applications can also be installed by .exe files.  .MSP – A Windows installer patch file. Used to patch applications deployed with .MSI files.  .COM – The original type of pro

Cross Domain Solutions Plug-in

The Glasswall Cross Domain Plug-in removes potential threats from files crossing multiple domains in and out of private or public networks. The Plug-in mediates the flow of files from a source location (e.g. Dropbox) onto the Glasswall CDR Platform which instantly cleans and rebuilds files to match their known good manufacturer's specification – then places the safe file to a destination location which is typically in a higher trust zone. How it worksCDR implementations can be chained together, as they span different domains to ensure that the process is double-blind. Files are processed in dedicated Kubernetes Pods and Containers which are destroyed once a sanitized file is emitted, ensuring the integrity of the environment.   Key benefitsGlasswall CDR platform is context agnostic about how the Cross Domain air-gap is established Multiple connectors available to define how the Cross Domain Plug-in communicates with storage repositories before passing the file to the Glasswall CDR Plat

What is the best solution if the system goes down?

We are always looking at improvements for our product and the service we can give to our customers. We are looking at 2 solutions for customers to have their say over. If there is a delay or a fault our engineers will be hard at work to get the systems back up and running, The 2 solutions we are working on for your continued service are the below, these will run parallel together so if queuing after 1 hour the delay is not resolved this will bypass Glasswall and emails will go straight to the recipient. Service bypass - Service will bypass Glasswall and emails/attachments will be sent to the recipient without Glasswall involvement until the incident has been resolved. This can be completed on our system so there will be no involvement needed by the customer and a report will be sent to cover the time the system was down and Glasswall can supply and attachments you wish to be rebuilt and sent directly to you during the downtime. Message queuing - We also have an option to queue emails f

Analysis and Protect mode

Analysis and Protect mode Glasswall Rebuild's unique patented approach provides the reassurance of total document security within normally communicated documents. This is achieved principally using a patented regeneration capability whereby only known good data is allowed to be generated to a sanitized, safe file.The engine has two broad modes of operation:Analysis: Provides a detailed report highlighting content that is contained within a file is shown Protect: File is analyzed and a safe, substitute copy is made.The Analysis mode enables the content of documents to be assessed with an XML report generated to summarise the non-conformances and potential threats. The Protect mode addresses the issues that are identified, returning an updated document with the remedies and sanitization changes necessary to remove threats within the original document.You can select mode by changing process mode in config file, 0 Analysis and 1 for Protect :  Analysis Mode OverviewIn Analysis Mode a file-

Glasswall Mail Service Policy

Glasswall mail service Policy allows users to create a unique set of rules for your account. This means that you can fully customize the way that this service is running. This can be very useful when working in a dynamic environment.  There are two major categories of rules. First one is dealing with what is to be done with a specific type of files. For example, all incoming word documents are to be clear of macros and the second major category is to set a rule based on sender and recipient address. For example, all incoming mail from sender X containing word document is allowed to have macros. Also, there are 3 policy categories regarding the time when the policy was or will be used: previous, current and draft policy. All rules and groups are created in the file trust administrator portal. https://portal.filetrust.io/                When setting up Policy first thing to do is to set up the main policy in regarding file type.This will allow you to create a unique rule for each file ty

Bounce Backs

 Bounce Back’s In The Transaction Logs You may see bouncebacks appearing in the transaction logs which may acquire when going live after the policy set up, even during configuration mode. They may not need to be action taken, check the following: Is the address’s non-reply address? Does the sender address have a relay endpoint? This may be for an example a news letter which does not require a reply and when the email is processed through the Glasswall engine the engine can not resolve the sender's address.

Add Exception for a Large File

How to Add an Exception for a Large File Glasswall Email Security allows any file up to 50MB through by default. However, if a file exceeds that size you will see the following alert: Warning: FileTrust Email - A tenants email has been bounced. on aks-cluster:uksprod1,message:the_received_message_of_52718694_bytes_exceeds_max_message_size_of_52428800_bytes.,tenant_name:companynameAn email has been bounced:- Tenant: companyname- Cluster: clustername- Reason: the_received_message_of_52718694_bytes_exceeds_max_message_size_of_52428800_bytes. Fortunately, there is a way we can implement an exception for those files so that they are not relayed through, via the Glasswall Portal.The changes are made via the Exchange Admin by adding an exception for files larger than 50MB, as shown below.
