Self-Defending SSD That Protects Data From Ransomware Attacks
Reading Time: 2 minutes

Cyber-security startup Cigent Technology built a self-defending SSD that protects data from Ransomware Attacks.

The self-defending SSD features Dynamic Data Defence Engine (D³E) software for Windows 10. It offers file-level Zero- Trust access controls and uses encryption and multi-factor access control. The company claims it makes data invisible when an attack is detected.

Cingent uses the D³E software in its Aspen, K2, and Denali Secure SSDs. The D³E Windows-based agent works with Phison E12DC-Crypto-SSD controller firmware. This combination provides ransomware detection and response to constantly protect data.

What is Cigent Secure SSD?

Cigent Secure SSD is the first of its kind to offer protection to storage devices with cybersecurity built into the firmware itself. It includes a dedicated security processor that uses machine learning to detect and respond to ransomware. While the keep alive sensors automatically encrypt sensitive files if security software is bypassed. When under attack it makes data invisible to any attacker. It keeps the sensitive files protected for the entire data lifecycle when paired with D³E.

According to Michael Wu, president and GM of Phison Electronics US, “As the world’s first and only self-defending solid-state storage devices, the Cigent Secure SSD family is a true breakthrough that challenges conventional thinking about data security.”Self-Defending SSD

According to the company, during a ransomware attack the system stores data in threat-aware virtual safe rooms; these cease to exist from the operating system’s point of view. A Dual Mode feature provides private/secure and non-private storage partitions independent and invisible to one another and to adversaries.

The drive data is encrypted automatically via the KeepAlive heartbeat feature in case the designated cyber-security software stops running.

Currently, both K2 Secure SSD and D³E software are available, while the Denali Secure SSD, with machine learning-based data protection, will be available in summer 2021.

The disk can be installed as primary storage on Windows PC, as secondary internal storage, or connected externally as USB media.
