Content Disarm and Reconstruction by link22 Data Guard
Content Disarm and Reconstruction (CDR) from Glasswall enhances protection against previously unknown threats and so-called zero-day attacks. With CDR, each file can be deconstructed, validated, cleansed, and reconstructed based on specifications of known and well-defined file types that are safe and permitted in your business. The capability of CDR allows you to shift from passive to active review and protect against zero-days where other solutions fall short.
Neutralizes Files
Content Disarm and Reconstruction neutralizes the content of files. If CDR is set up in the secure solution for importing/exporting information, the file is taken apart, verified, and reconstructed into a secure file with the same informational content. This makes it much harder for perpetrators to send unwanted code hidden in regular files.
Protection against the unkown
Firewalls and filters search for known threats, viruses, or other software classified as malicious. Therefore, they do not protect against undiscovered threats, such as Zero Day attacks. CDR solves this problem by transforming every file into a harmless one, regardless of whether the original file was malicious or not.
Perfect for link22 Cross Domain Solution
link22 has developed a seamless integration to make it easy to combine our products with Glasswall's CDR. The CDR feature is an excellent complement to link22's Cross Domain Solution. This technology can be used for both import and export of information, and it can also be applied between security domains.

CDR in four steps
1 – Inspect
Three layers of the file are inspected to validate that its digital DNA aligns with the manufacturer's specifications for a harmless file. Actions are taken immediately where discrepancies are detected.
2 – Cleanse
Active content of a risky nature (e.g. macros and embedded links) is cleansed and removed, based on your policy - only those users who need active content will receive it.
3 – Re-create
The file is reconstructed according to the manufacturer's standard for a harmless file type, ensuring that the file is clean and free from threats.
4 – Deliver
The user has imported a secure, approved, standardized, and trusted file.
