In today’s world, cybersecurity is crucial for every industry, but the stakes are even higher in industries that depend on Operational Technology (OT). The role of an OT Cybersecurity L2 SOC (Security Operations Center) Analyst is integral in ensuring that critical OT systems remain secure from cyber threats. In this article, we’ll dive deep into the responsibilities, skills, tools, and challenges faced by an OT Cybersecurity L2 SOC Analyst, as well as the importance of specific technologies like Nozomi Networks and MITRE ATT&CK in the OT landscape.
What is OT Cybersecurity?
OT cybersecurity is the practice of protecting industrial control systems (ICS), such as SCADA (Supervisory Control and Data Acquisition) systems, Distributed Control Systems (DCS), and Remote Terminal Units (RTUs), from cyber threats. Unlike IT (Information Technology) cybersecurity, which deals with traditional computer systems, OT cybersecurity focuses on the protection of hardware and software used to monitor and control industrial processes.
OT systems often have critical functions in industries like energy, manufacturing, transportation, and utilities. A security breach in these sectors could have severe consequences, including equipment damage, environmental harm, and safety risks. This is why securing OT systems is essential for maintaining operational integrity.

An L2 SOC Analyst in OT cybersecurity has various key responsibilities aimed at ensuring the security of industrial networks and systems. Some of the primary duties include:
Monitoring OT Network and Systems
An L2 SOC Analyst is responsible for monitoring the OT network 24/7, looking out for any unusual activities or security breaches. The role demands attention to detail and the ability to quickly identify and respond to threats.
Incident Detection and Analysis
Once a potential security threat is detected, an L2 SOC Analyst must quickly analyze the incident. This could involve identifying vulnerabilities in the system, understanding the scope of the threat, and determining the impact on operations. The analyst works to mitigate the threat as quickly as possible.
Collaboration with OT Teams and SMEs
An effective L2 SOC Analyst needs to work closely with OT subject matter experts (SMEs) and department teams to resolve security incidents. This collaboration is crucial for addressing technical challenges and ensuring that all OT systems are properly secured.
The Critical Role of an L2 SOC Analyst in Identifying OT Threats
The L2 SOC Analyst plays a vital role in identifying and responding to cyber threats. Their day-to-day duties may include:

To be successful as an L2 SOC Analyst in OT cybersecurity, specific skills and knowledge are crucial:
Expertise in OT Networking Devices and Protocols
An L2 SOC Analyst must understand how OT networking devices and systems, such as DCS, SCADA, and RTUs, communicate within the broader industrial network. Familiarity with OT networking protocols is essential for detecting anomalies and potential threats.
Knowledge of ICS, DCS, and SCADA Systems
The analyst should have in-depth knowledge of ICS (Industrial Control Systems), DCS (Distributed Control Systems), and SCADA (Supervisory Control and Data Acquisition) systems. These systems control critical infrastructure, and understanding their vulnerabilities is key to cybersecurity.
Familiarity with OT Security Tools and Vendors
The L2 SOC Analyst should also be familiar with various OT security tools, vendors, and solutions, such as Nozomi Networks, and have the ability to choose the right tools for the job.
The Role of MITRE ATT&CK in OT Cybersecurity
MITRE ATT&CK is a globally recognized framework for understanding and combating cyber threats. In the context of OT cybersecurity, MITRE ATT&CK can help analysts map out adversary tactics, techniques, and procedures (TTPs) based on real-world observations.
How MITRE ATT&CK Helps in OT Security
The framework provides a structured approach to understanding the various stages of a cyberattack, from initial access to execution. By mapping these stages to the OT environment, L2 SOC Analysts can better prepare for and respond to attacks.
Incident Management and Reporting in OT Cybersecurity
An L2 SOC Analyst must be adept at managing and reporting incidents efficiently. This involves:
- Incident detection: Identifying anomalies or security breaches in real time.
- Prioritizing vulnerabilities: The analyst must assess the severity of incidents and prioritize remediation efforts accordingly.
- Collaboration with OT CISO GRC: Ensuring incidents are resolved in line with agreed Service Level Agreements (SLAs) and reporting them to the relevant stakeholders.
Vulnerability Management in OT Cybersecurity
OT systems are complex and vulnerable to various threats. Therefore, managing vulnerabilities is a significant part of the L2 SOC Analyst’s role. This involves:
- Conducting vulnerability assessments: Regularly scanning OT systems for potential weaknesses.
- Applying patches and updates: Ensuring timely application of security patches to reduce exposure to cyber threats.
Security Audits and Compliance in OT Cybersecurity
Security audits play a vital role in maintaining compliance with industry standards. An L2 SOC Analyst assists in preparing for internal and external audits, ensuring that OT systems meet regulatory requirements.
Threat Intelligence Sharing in OT Cybersecurity
Sharing threat intelligence with industry peers and relevant agencies is a key component of OT cybersecurity. It allows analysts to stay informed about emerging threats and strengthens the defense mechanisms across the industry.
Challenges and Opportunities in OT Cybersecurity
While the role of an OT Cybersecurity L2 SOC Analyst is rewarding, it does come with its unique challenges. These include:
