Chatgpt for cybersecurity: practical applications, challenges, and future directions

Artificial intelligence (AI) advancements have revolutionized many critical domains by providing cost-effective, automated, and intelligent solutions. Recently, ChatGPT has achieved a momentous change and made substantial progress in natural language processing. As such, a chatbot-driven AI technology has the capabilities to interact and communicate with users and generate human-like responses. ChatGPT, on the other hand, has the potential to influence changes in the cybersecurity domain. ChatGPT can be utilized as a chatbot-driven security assistant for penetration testing to analyze, investigate, and develop security solutions. However, ChatGPT raises concerns about how the tool can be used for cybercrime and malicious activities. Attackers can use such a tool to cause substantial harm by exploiting vulnerabilities, writing malicious code, and circumventing security measures on a targeted system. This article investigates the implications of the ChatGPT model in the domain of cybersecurity. We present the state-of-the-art practical applications of ChatGPT in cybersecurity. In addition, we demonstrate in a case study how a ChatGPT can be used to design and develop False data injection attacks against critical infrastructure such as industrial control systems. Conversely, we show how such a tool can be used to help security analysts to analyze, design, and develop security solutions against cyberattacks. Finally, this article discusses the open challenges and future directions of ChatGPT in cybersecurity.
