ATTACK SURFACE IN THE CONTEXT OF ITS USERS (“TREAT ACTORS”) FOR CRITICAL INFRASTRUCTURE FACILITIES

Abstract

In the modern digital world, where information technology is an integral part of life, cybersecurity issues are becoming increasingly relevant. One of the key aspects of protecting information systems is managing the attack surface, which includes all possible entry points for malicious actors. Forming and managing the attack surface is a complex task that requires constant attention and improvement. Malicious actors (“Threat actors”) play a crucial role in this process. They constantly seek new ways to penetrate systems, using various methods and techniques. These “actors” can vary in their origins and motivations: from cybercriminals seeking financial gain to state actors conducting espionage and sabotage activities. Understanding the types of “malicious actors” and their methods is essential for effective attack surface management. This understanding helps to timely detect and eliminate vulnerabilities, improve system and network configurations, and raise staff awareness of modern cyber threats. This article examines the key aspects of forming the attack surface, focusing on the role of “malicious actors”. It explores the types of “malicious actors”, their methods and techniques, and provides practical recommendations for reducing risks and improving the protection of information systems. Additionally, conducting regular security audits and implementing modern protection technologies such as intrusion detection systems, data encryption, and multi-factor authentication are important. Thus, a comprehensive approach to managing the attack surface, which includes understanding “Threat actors”, utilizing modern protection technologies, and continuously training personnel, is crucial for effectively protecting the information systems of critical infrastructure.
