Introduction
The maritime industry, as a vital component of international trade, has witnessed a growing prevalence of cyber threats. The digitization of ship and port operations has led to an increase in the number and complexity of cyber threats. 

BIMCO (Baltic and International Maritime Council) is a significant organization that establishes various standards and guidelines for the maritime industry. In recent years, BIMCO has placed significant emphasis on the issue of cyber security. BIMCO's guidelines and rules on cyber security have been established with the objective of ensuring that ship operators and interested parties are protected against cyber threats.

It is of paramount importance for the maritime industry to prioritize cybersecurity, as it directly affects operational efficiency, the prevention of financial losses, and the protection of human life. The functionality of digital systems utilized in maritime operations, including ship voyages, port operations, and supply chain management, may be compromised as a consequence of cyber-attacks. Such incidents can result in significant economic losses and operational disruptions. Moreover, attacks on the control systems of ships can potentially compromise the safety of the crew and the environment.

Cyber Security in the Maritime Industry
The key point regarding BIMCO's cyber security rules and guidelines is the Cyber Security Management Plan (CSMP). It is a regulatory requirement that every ship be equipped with a cyber security management plan. The plan should encompass the measures and procedures to be implemented for the ship's operational systems, networks, data, and information management. In addition, the CSMP should include training and awareness programs for both onshore and offshore personnel. It is recommended that regular cyber risk assessments be conducted and that appropriate security measures be taken in line with the results of these assessments. The risk assessment is employed to ascertain the susceptibility of both the ship and the company to cyber threats.

The maritime industry places a high degree of importance on cyber security, as it is directly related to the safety of ships, cargo, and personnel. In the context of maritime cybersecurity, the term "IT" (Information Technology) and "OT" (Operational Technology) systems refers to the protection of digital and operational systems, respectively, against unauthorized access, manipulation, and disruption. While information technology (IT) systems facilitate communication and data flow between the ship and shore offices, operational technology (OT) systems regulate the physical operations of the ship. Consequently, the security of both systems is of paramount importance.

The maritime industry is confronted with a plethora of cyber threats. These include malware, ransomware, social engineering attacks, denial of service (DoS) attacks, and data breaches. Malware can infect ship systems, resulting in operational disruptions and data leakage. Ransomware can render ship and port systems inoperable and demand ransom from businesses, potentially leading to operational shutdowns. Social engineering attacks can result in the compromise of critical information by misleading crew and personnel. Denial-of-service (DoS) attacks can target ship and port systems, resulting in the disruption of services and difficulties in accessing these systems. Data breaches can result in financial losses and reputational damage due to the unauthorized access of sensitive data.

BIMCO's cyber security rules provide a comprehensive framework for the protection of ship owners, operators, crew, and all interested parties. The objective of these rules is to safeguard ships and maritime operations in the context of digital transformation and the intensifying cyber threats facing the maritime industry.

Cyber Incidents and Risks
The maritime industry is susceptible to a variety of cyber incidents, which can occur in a number of ways.

Corruption of electronic chart data may occur in a number of ways. The corruption of the chart data stored in the Electronic Chart Display and Information System (ECDIS) may result in the ship navigating on the incorrect course.

Another potential avenue for infection is the use of an infected USB drive. The use of an infected USB drive during software maintenance can result in system failures and data loss.

Existing Vulnerabilities and Management Strategies
The maritime sector is confronted with a multitude of challenges, including the utilisation of antiquated and obsolete systems, the involvement of a multitude of stakeholders, and the necessity for remote access. In light of these considerations, it is recommended that companies adopt the following management strategies:

In the context of a multi-stakeholder environment, it is necessary to consider the involvement of various stakeholders and the potential challenges that this may present. Given the multitude of stakeholders involved in the operation and chartering of a vessel, there is a risk of a lack of accountability for IT and OT system infrastructure and vessel networks.

• Legacy Systems: The utilization of IT and OT systems that are no longer supported or based on legacy operating systems is a prevalent phenomenon.

• Remote Access and Monitoring: The remote monitoring and access of shipboard equipment by manufacturers or support providers renders it susceptible to cyber-attacks.

• Comprehensive Cyber Security Policies: Such policies should include measures to protect against cyber threats, incident response plans, and regular risk assessments.

Training and awareness programs are essential for ensuring the security of shipboard IT and OT systems. It is imperative that all personnel on board the vessel receive regular training and information on the subject of cyber security.

Technical and procedural security measures are essential for the protection of shipboard equipment. It is imperative that advanced technological solutions and security protocols be implemented in order to minimise the potential for security vulnerabilities.

Maritime Cyber Security and Legal Obligations
The maritime industry is characterized by a multitude of technological and operational systems, which necessitates the implementation of cybersecurity measures to safeguard these systems from unauthorized access, manipulation, and disruption. The International Maritime Organization (IMO) is a pivotal organization in the establishment of maritime security standards, and the IMO has mandated that all ship operators incorporate cyber risk management into their security management systems by 2021.

The IMO requires the maritime industry to integrate cyber risk management into security management systems. These regulations require ship owners and operators to assess and manage cyber security risks.

EU General Data Protection Regulation (GDPR): In addition, cybersecurity should be considered in the context of the EU General Data Protection Regulation (GDPR) and similar international regulations. Such legislation increases maritime companies' obligations to report data breaches and notify affected individuals.

Implementation Strategies and Recommendations:
In order to ensure cyber security in the maritime industry, a number of measures should be taken. Firstly, training crew and personnel on cyber security and increasing their awareness can help prevent social engineering attacks.
