This dependence on the technology aspects has also resulted in increased vulnerability from attacks by hackers and other unauthorized persons on the internet. Various cybersecurity threats such as malware, ransomware, phishing, social engineering, insider threats, advanced persistent threats (APTs), and data breaches, have continuously caused loss of personal data as well as financial loss for companies. This research discusses these major cybersecurity threats that companies need to understand and put up measures to curb any unauthorized access to their systems. The key regulatory framework such as those outlined by HIPAA and FDA, are also explained and how companies can make sure they adhere to such guidelines. A detailed explanation of CISOs functions in pharmaceutical industry companies is also detailed herein. Keywords: Malware, ransomware, phishing, social engineering, insider threats, advanced persistent threats (APTs), data breaches I. INTRODUCTION The pharmaceutical industry is responsible for the development of drugs as well as their processing and distribution to all parts of the supply chain. As the industry continues to grow in leaps and bounds, it has been forced to embrace better means of managing its resources and operations. For instance, they have been able to adapt some form of IT systems to automate and simplify their manual processes as well as ensure that there is real-time monitoring of transactions in the supply chain. They have been able to adopt technology in operations ranging from research and development (R&D) to manufacturing and distribution. These processes require huge data handling and processing which therefore means that the system needs high data integrity and protection of intellectual property to ensure data security [5]. IT systems enable pharmaceutical companies to store and analyze vast amounts of data, streamline clinical trials, manage supply chains, and comply with regulatory requirements. The industry is therefore prone to cybersecurity threats due to the high value data that is held. There have been several data breaches in the past that have led to loss of crucial data and financial losses. It therefore is crucial to understand the cybersecurity threats that are present and how to protect against these threats so as to ensure continued trust from stakeholders and regulatory bodies. By exploring the nature of these threats and the potential impacts of security breaches, the paper seeks to provide a comprehensive understanding of the current cybersecurity landscape within this sector. II. OVERVIEW OF PHARMACEUTICAL IT SYSTEMS There are several types of IT systems available for the pharmaceutical industry. Research and development (R&D) databases is the first type where they facilitate the collection, storage, analysis, and sharing of experimental data, enabling researchers to identify potential drug candidates, conduct preclinical studies, and manage the results of laboratory experiments [12]. This means that they store large data and they can be integrated with bioinformatics tools and models that can help hasten the process of drug discovery by ensuring accurate and efficient predictions. There are also manufacturing and supply chain management systems. These systems provide critical information on the movement and distribution of pharmaceutical products along the supply chain [9]. Information from the raw materials processing to finished goods dispatch is contained in thus system. They therefore help in tracking inventory levels, managing production schedules, and ensuring quality control. These systems are important in the pharmaceutical industry as they bring about transparency in logistical flow of drugs and other pharmaceutical products ensuring on time delivery complying with regulatory standards and reducing risks in the supply chain [6]. Another IT system in the pharmaceutical industry is the clinical Trial Management System. This system is involved in the entire testing and development phase of drugs. For instance, it is involved in the planning, tracking, and management of clinical trials.
