MetaDefender Storage Security v3.4.0

Release Date: 13 May 2024

Version support until 13 November 2025

We're excited to announce major updates to our Windows Native Applications.

This release not only boosts functionality and system security but also improves user access, reflecting our ongoing dedication to enhancing user experience. Key updates include integration with Oracle Cloud Object Storage (OCI) via AWS SDK, streamlined Single Sign-On (SSO) support for MDSS using Active Directory Federation Services and OpenID Connect, and bolstered API security.

Highlights
  • Exciting Enhancements to Our Windows Native Applications by providing:
  • Dynamic Service Orchestration: New service manages, orchestrates, and heals MDSS processes based on module settings.
  • Registry Scan to Prevent Installation Conflicts: Prevents version 3.4.0 from being installed over Docker-based setups.
  • Performance Boost by Replacing Docker with Native Processes: Enhances stability and utilizes full system resources by transitioning to native processes.
  • Enhanced Cache Management with MongoDB: Integrates MongoDB to improve caching operations as a robust alternative to Redis on Windows.
  • We are announcing a new integration capability with Oracle Cloud Object Storage (OCI) via AWS SDK: This integration employs path-based access to connect to OCI, accommodating the platform's limitation on not supporting virtual hosted access.
  • We've introduced Single Sign-On support for MDSS using Active Directory Federation Services and OpenID Connect, streamlining login processes and enhancing security and user experience for seamless authentication and easier access management.
  • Strengthened API Security Enhancements against various security vulnerabilities, ensuring a more secure and reliable environment for our users: Enhanced HTTPS Enforcement, Strict-Transport-Security (HSTS) Implementation, X-Content-Type-Options Header Upgrade, Mandatory Operation Security Field
Performance, Security, and Usability Enhancements
  • Stress Testing Enhancements: Conducted stress tests under heavy load on a machine with 8 cores and 16GB of RAM, where RabbitMQ and MongoDB utilized 25% of RAM, in both AWS and SMB environments.
  • Improved Real-Time Processing for NFS: Enhanced Real-Time Protection with Deep Content Disarm and Reconstruction for NFS on Windows shares, improving security performance.
  • Streamlined Command-Line Upgrading for MDSS: Updated the command-line upgrade process to consistently display the EULA page, particularly when using clean commands or exporting support packages, enhancing user compliance and experience during upgrades.
  • Event Limitation and Scaling Guidance: Implemented an event limitation in the discovery process; the system will pause when it reaches 5,000 events. Users are encouraged to scale up their systems to maintain continuous operation.
  • DocumentDB Integration: Successfully integrated our system with DocumentDB, enhancing our database management capabilities.
  • Storage Limitation and UI Enhancements for Simpler Deployments: Introduced a storage limitation per instance to prevent overload and added UI warnings for excessive CPU usage, along with a sizing guide to help customers effectively scale their systems.
