Content Disarm & Reconstruction (CDR)

Content Disarm & Reconstruction is a computer security technology for removing potentially malicious code from files. Unlike malware analysis, CDR technology does not determine or detect malware's functionality but removes all file components that are not approved within the system's definitions and policies. It is used to prevent cyber security threats from entering a corporate network perimeter. Channels that CDR can be used to protect include email and website traffic. Advanced solutions can also provide similar protection on computer endpoints, or cloud email and file sharing services. There are three levels of CDR - 1) flattening and converting the original file. 2) stripping active content while keeping the original file type. 3) eliminating all file-borne risk while maintaining file type, integrity and active content.
