Content Disarm and Reconstruction (CDR) is an advanced cybersecurity technology designed to neutralize threats, such as malware and ransomware, within files.
CDR works by disassembling files (documents, images, etc.) and removing any potentially malicious elements. Advanced CDR solutions, such as Glasswall CDR technology, are able to retain a document’s original functionality and appearance – providing seamless protection to the end user.
Content Disarm and Reconstruction plays a crucial role in enhancing an organization’s cybersecurity strategy. Here are 4 reasons why CDR is considered one of the most effective file protection solutions:
CDR is a zero-trust data filter that rebuilds files and documents into a safe, clean standard, free from the risks of malware. CDR prevents malicious files from entering a network and is used for secure file transfer across trust boundaries.
Unlike detection-based solutions, CDR doesn’t try to identify malicious code – it simply removes the ability for it to exist altogether. This zero-trust approach disarms often overlooked advanced persistent threats, such as zero-day malware, high-risk active code and anomalies within a file’s structure.
Many conventional data filters flatten files (turn them into images) for use in high risk environments. Files cleaned by CDR are visually identical and fully functional, meaning you get your report – not a pancake.
CDR offers organizations comprehensive analysis of the threats within files, empowering security teams to remove or manage high-risk content according to their risk appetite.
While our recommendation is that CDR should be used as one component of a wider cybersecurity strategy, it is helpful to understand the significant advantages CDR has over other file protection technologies.
Glasswall CDR employs our patented 4-step approach to protect government agencies and organizations against file-based threats. Unlike other cybersecurity solutions, we don’t try to identify the malicious code – we simply remove the ability for it to exist in the file altogether.
Breaks down the file into its constituent components. Validates the file’s structure against its specification
Unknown and invalid file structures are repaired in-line with the file’s specification
Removes high-risk file structures that contain active content, based on configurable policy
Semantic checks ensure the file’s integrity. The safe and fully functional file is now ready to use
