From Firewall to AI: Strengthening Linux Server Security

Abstract

Nowadays, cybersecurity issues are constantly increasing. Some of the main challenges are the rapidly evolving threat landscape, the lack of skilled cybersecurity professionals, complexity of IT environments and emerging technologies, Zero-Day vulnerabilities, lack of international cooperation, user behavior and social engineering. The selection of an operating system can significantly influence the establishment of robust defenses against cyber threats. Now, many strategies are known for defense-in-depth of critical server infrastructure, but the ever-increasing sophistication of cyber-attacks must also be considered. When a previously unknown attack occurs, a defense system must be able to recognize it and act. The current development of Artificial Intelligence (AI) makes it possible to create this type of intelligent protection. This paper aims to provide an overview of some of the most renowned traditional practices and explores the potential of leveraging a neural network model to enhance cybersecurity used to protect Linux servers against cyber-attacks.
