An Offline Cybersecurity Device for U.S. Small Businesses: Detecting Ransomware and Restoring Data Without Internet or Cloud

Abstract

During the digital era, ransomware has become a severe problem for the cybersecurity of small and medium-sized companies (SMEs) in the United States. Compared to massive companies with well-developed cybersecurity systems, a small business lacks capabilities and resources, which makes such an enterprise extremely vulnerable to cyber attacks. Ransomware, malicious encryption of user data combined with extortion of the decryption keys, has become more mature as an attack method, in its occurrence rate, and scale. Most of the present day solutions aimed at cybersecurity largely depend on the cloud and internet connectivity as means to monitor and report events in real-time, make back-ups and restore a system. Nevertheless, this dependence results in several points of failure, especially when the internet goes down in an outage after an attack or when other services (like cloud-based) become unavailable as well.

The current research introduces a brand new, all offline cybersecurity solution that caters exactly to the requirements of small businesses in the United States. The technology of this system is designed in a manner that it functions independently without using internet or cloud. It includes a hybrid ransomware detection model of both signature-based and behavior-detected analytics and a locally based air-gapped local backup system that runs in real-time. Through the same, the device will guarantee constant protection, continuous identification of questionable activity as well as quick data recovery amid and following ransomware attack.
