Content Disarm & Reconstruction

Content Disarm and Reconstruct (CDR) removes malicious elements from files by breaking them down into individual components, analyzing them for threats, and rebuilding them into sanitized versions. Unlike traditional file scanning solutions, CDR guarantees malware-free content without relying on detection-based methods, making it an essential tool for secure environments.

Overview

Content Disarm and Reconstruction (CDR) is an advanced cybersecurity technology designed to neutralize threats embedded in files by breaking them down, removing potential malicious code, and rebuilding safe, usable versions of the content. CDR assumes all files are potentially malicious and proactively eliminates risks rather than relying on detection-based methods.

CDR is widely used in industries such as government, defense, critical infrastructure, and enterprise IT, where secure file transfer and handling are essential.

Key Objectives of Content Disarm & Reconstruction (CDR)

Threat Neutralization

Proactively removes malicious code, scripts, or macros embedded within files to prevent potential cyberattacks.

File Integrity Preservation

Ensures the sanitized files remain functional and retain their original format and usability.

Prevention of Zero-Day Attacks

Eliminates threats without relying on signature databases or known malware indicators, making it effective against zero-day vulnerabilities.

Compliance

Assists organizations in meeting security standards such as ISO 27001, GDPR, and NIST by safeguarding sensitive data exchanges.

Workflow

File Ingestion: Files are received from external or internal sources (e.g., email attachments, uploads, or file transfers).
File Decomposition: The file is broken into core elements (e.g., metadata, content, scripts).
Threat Removal:Malicious elements are stripped from the file. Examples include:
- Macro removal from Word documents.
- JavaScript removal from PDFs.
- Embedded executable code removal.
File Reconstruction: A clean version of the file is rebuilt, retaining its original format and usability.
Delivery: The sanitized file is sent to the intended recipient or destination, ensuring it is safe to access.
Monitoring and Auditing: All file processing activities are logged for monitoring and compliance.
