A Comprehensive Review on Encryption based Open Source Cyber Security Tools

With the worldwide migration of workloads on internet and doud based platforms, maintaining security has become a major bottleneck in business workflows. Open source security tools are widely available for maintaining network security, endpoint security, system security etc. However, there exists a gap in adoption of these tools amidst end users. In This work, we have reviewed encryption based open source cybersecurity tools for a detailed study and comparison under different categories. Numerous open source tools are investigated which can be used by cyber security industries, academia, hackers and business institutions across the world. A comprehensive review of the tools is provided so as to guide anyone who wants to explore encryption based tools in today’s rapidly evolving digital world.

I. Introduction

In the last decade, the focus of IT businesses has shifted towards cybersecurity - thereby making it one of the foundations for computational service delivery and providing security. Despite having a good cybersecurity infrastructure and personnel training; cyberattacks and threat vectors have evolved at an unprecedented rate [1]. In 2019, 21 million passwords and 770 million email addresses were exposed from the MEGA cloud service which was later named “Collectionl” as nearly 1 TB of critical data was leaked. Half a billion Facebook user records, 100 million user records of JustDial in India, personal medical data of 1 million users in New Zealand, 3 million customer details from a banking firm UniCredit in Italy were exposed by various online cyberattacks [2].
