In the real world an unexpected aspect is how attacks occur like in the 2015 Ukraine power grid hack show OT vulnerabilities, highlighting the need for robust security in converged setting, which isn't always immediately obvious to the laypeople.

Survey Note: Detailed Analysis on Convergence of IT and OT Security

Convergence of information technology (IT) and operational technology (OT)is emerging as a critical area in cyber security, particularly as industries increasing digitalize their operations. This survey note explores the topic in depth providing a comprehensive overview for professionals and lay readers. the information is from a research process and all details are included.

Background and definitions

IT encompasses system and technology used to manage and process information on the networks, computers, servers and databases. Its primary focus is on ensuring that the data is safe, privacy and availability. OT on the other hand refers to the systems that control physical processes in the industries including industrial control system (ICS) supervisory control and data acquisition (SCADA), and programmable logical controllers (PLCs). OT prioritize the reliability availability and safety of these physical processes often in the sector like manufacturing, transportation and energy.

Historically, IT and OT were operated in SILOS with OT systems frequently air-gapped-isolated from networks-for security. However, with the advancement of the industry 4.0 the Internet of things (IOT), and the need for the real-time data analysis, there is growing trend to integrated IT and OT, allowing them to share the data and work together more efficiently. This convergence is driven by the desire for more enhanced operational work which will increase visibility automation and cost saving. As the enhancement occurred it also introduced certain significant cyber security challenges for cyber experts.

Why Convergence is happening

The convergence happened by the several factors:
Operational Efficiency: The connection between the IT and OT enables real-time data analysis improving decision making and reducing downtime.
Technological Advancement: As the rise of IOT, AI and machine learning in industrial setting necessitates integration for data driven insights.
Cost saving: Optimizing the processes and resources utilizing it can lower the operational costs.
Industry 4.0: The fourth industrial revolution emphasizes the smart factories which are interconnected with the systems requiring IT and OT to work together.

There are various benefits which includes better visibility into operations, enhanced data-driven decision-making, increased automation, and improved customer experiences through personalized services. For instance, manufacturing plant can also use IT system to analyze sensor data from OT equipment, optimizing production lines in the real time.

Security Challenges in Converged Environments

As the integration expands these attack surfaces exposes the OT systems, which are traditionally isolated to the same cyber threat as IT systems. Key challenges include:

Expanded Attack Surface: When there are more connections and devices mean more potential entry point for attackers increasing vulnerability.
Diverse Technologies: The IT and OT use different technologies and protocols (example IT use TCP/IP, while OT often use its proprietary protocols), making uniform security measure difficult to implement.
Legacy Systems: As many OT systems are older, and were designed decades ago, and may lack built-in security features like encryption or patch management which are complicating updates.
Different Security Priorities: IT focuses on protecting data through confidentiality, and integrity, and availability (the CIA triad), while OT prioritizes ensuring the availability and safety of physical processes. This difference leads to conflicting security approaches.
Skills Gap: The security professionals may lack expertise in both IT and OT, requiring cross-training or hiring specialists, which can be resource-intensive. As both fields are different form each other.
Regulatory Compliance: IT follows rules like GDPR (General Data Protection Regulation) for data privacy, while OT has specific standards like NERCCIP (North American Electric Reliability Corporation Critical Infrastructure Protection) for energy. These differences make it more compliance and challenging to understand.

These challenges are exacerbated by the fact that OT systems often have a longer life cycle than IT systems with some equipment designed to last decades, making it harder to integrate modern security protocols.

Strategies for Securing Converged IT and OT Environment

To address these challenges organizations, need a holistic psychotic strategy to consider both it and OT the following step are recommended:

Risk Assessment: Identify the critical assets and potential threat to prioritize security efforts this involves mapping all the IT and OT system and assessing their vulnerabilities.
Zero-Trust Model: By implementing a zero-trust approach where every user and device is verified before granting access regardless of network location. This minimizes unauthorized access and lateral movement in the case of breach.
Network Segmentation: Isolate IT and OT networks where possible by using firewalls, and VLANs to limit the spread of attacks. This creates a defense-in-depth strategy reducing the risk of single point of failure.
Regular Updates and Patches: To keep all systems, including legacy OT systems, up to date with the latest security updates with the latest vendors to ensure compatibility and availability and updates.
Monitoring and Detection: The use of advanced monitoring tool such as security information and event management SIEM system to detect anomalies and potential security incidents in real time this is crucial for both IT and OT even their interconnected nature. By measuring these advance monitoring tools, the system will be more protected.
Employees Training: Educate employees on the security best practices to reduce the risk of human error, such as falling for phishing attacks, which can be a gateway for OT system breaches.
Incident Response Plan: Develop and regularly update incident response plan to handle security incidents efficiently, ensuring minimal disruption to operations and compliance with regulations.

Additional best practices include using secure communication protocols example (TLS for data in transit), implementing multi-factors authentication and two step verification for the access of critical systems, and conducting regular security audits and vulnerability assessments. Collaboration with vendors is also essential to ensure their product are secure and receive timely updates.

Real-World Examples and Case Studies

The Importance of Securing Converged IT and OT Environments is evident in several high-profile incidents:

Ukrainian Power Grid Hack (2015): Attackers used spear-phishing to gain access to utility's IT network, then moved laterally to OT systems, causing a power outage affecting thousands of people. This incident is detailed posted on many websites which was highlighted globally, the vulnerability of OT systems when connected to IT networks.
WannaCry Ransomware Attack (2017): This global ransomware attack not only affect the IT networks but also the OT systems in various industries, such as manufacturing and healthcare, causing significant operational disruptions. It underscores the need for robust security in converged environments, as noted in (20 emerging cybersecurity trends) article.

These examples illustrate the real-world impact of security failures, emphasizing the need for the proactive measures in converged settings.
