As an OT Security Specialist, my job is all about keeping our critical infrastructures safe and secure. You may not think about it often, but many of the fundamental services we rely on every day – things like electricity, water, and transportation – are vulnerable targets for nefarious actors looking to cause chaos and destruction. That’s where I come in – my job is to assess and fortify the security of these essential systems, ensuring that they remain operational and available to those who rely on them. In this brief introduction, I’ll provide an overview of what an OT Security Specialist does, and explain why the work we do is so critical to our way of life. So, let’s jump in!

What does an OT security specialist do?

As an OT security specialist, your main focus is to evaluate the security of a client’s operational technology and identify potential vulnerabilities that could compromise their systems. You will conduct security assessments and reviews of their security risk landscape, providing advice on improvements and developing strategies, roadmaps, and innovative operating models that help clients make these improvements. Here are some of the key responsibilities of an OT security specialist:

  • Identifying potential vulnerabilities in a client’s operational technology and developing strategies to address them
  • Conducting security assessments and reviews of the client’s security risk landscape to identify areas that need improvement
  • Providing advice on best practices for securing operational technology
  • Developing innovative operating models that help clients to improve their security posture
  • Designing and implementing security protocols that protect operational technology from cyber threats
  • Collaborating with cross-functional teams to ensure that all stakeholders are informed of potential security risks and are taking appropriate measures to secure the systems
  • Whether you are working independently or as part of a larger team, your work as an OT security specialist will be critical in helping clients to protect their systems and data from cyber threats. This role requires a keen understanding of operational technology, as well as a deep knowledge of security best practices and protocols.


    ???? Pro Tips:

    1. Conduct regular assessments and vulnerability scans to identify potential security threats and risks to the operational technology (OT) system.
    2. Implement best practices based on industry standards to secure the OT environment, including network segmentation, access control, and encryption.
    3. Train employees and stakeholders on safe cyber behaviors and the importance of OT security.
    4. Monitor OT systems for suspicious activity and take proactive measures to prevent attacks.
    5. Develop incident response plans to quickly and efficiently respond to any security incidents that occur on the OT system.

    Assessing Clients’ Operational Technology Security Risks

    As an OT security specialist, one of the primary responsibilities is to assess the client’s operational technology and security risks. This includes analyzing the client’s security landscape and identifying any vulnerabilities that expose the organization to potential threats. The assessment is usually done through interviews with key stakeholders within the organization, examining the systems in use, and identifying areas that require attention.

    A comprehensive risk assessment helps to identify potential threats that the organization may face, such as malware, cyber-attacks, or physical damage to equipment or infrastructure. The assessment also helps to identify weaknesses in the client’s security protocols and procedures. Based on the assessment findings, the specialist can then provide recommendations and develop strategies to mitigate risk and improve security.

    Providing Recommendations for Improvement

    After conducting the security assessment, the OT security specialist can provide advice to clients on how to improve their operational technology security posture. Recommendations might include implementing specific hardware or software solutions, changing policies related to user access, or improving disaster recovery and business continuity plans. The specialist may also need to advise on the trade-offs between security and operational considerations to help clients find the right balance.

    It is essential to provide clear and concise recommendations that clients can easily understand and implement for maximum effectiveness. The recommendations provided should align with the industry best practices and should be tailored to the client’s specific needs and concerns.

    Developing Security Strategies and Roadmaps

    Based on the recommendations provided, the OT security specialist can develop comprehensive security strategies and roadmaps that help clients prioritize and address the identified security risks. The specialist may need to engage with senior management and other key stakeholders to get buy-in and commitment to implement the security strategies.

    The security roadmap outlines specific milestones and key performance indicators (KPIs) that the client should achieve to improve their security posture. The roadmap may also include timelines, budgetary estimates, and any necessary resources needed to achieve the desired outcomes.

    Creating Innovative Operating Models

    Innovation is essential in cybersecurity, and the OT security specialist should be constantly looking for new ways to improve an organization’s security posture. Innovative operating models can help clients stay ahead of emerging threats by developing comprehensive security solutions that include both technical and operational controls.

    Implementing innovative operating models requires the specialist to be familiar with the latest security technologies and trends. The specialist may need to research and analyze emerging threats and adjust their approach to mitigate risks effectively. Operating models may include the use of proactive threat hunting, behavioral analytics, and incident response strategies.

    Staying Current with the Latest Security Technologies and Threats

    One of the most critical aspects of an OT security specialist’s role is to stay up to date with the latest security technologies and threats. The specialist must stay informed about new security threats, exploits, and zero-day vulnerabilities that could threaten the security of the client’s operational technology systems.

    Security resources, such as industry news feeds, online training, and certifications, can help the specialist stay informed and current with the latest security trends. Cybersecurity is a constantly evolving industry, and staying up to date with the latest developments is essential to providing effective security solutions.

    Collaborating with Clients on Security Implementation Plans

    Once the security roadmap is developed, and the innovative operating models are in place, the OT security specialist will collaborate with the client to implement the security strategies. Collaboration is critical to ensure that the implementation process is seamless. The specialist may also need to address any concerns that the client may have during the implementation process.

    Collaboration throughout the implementation process helps to ensure that the client is satisfied with the security solutions provided and understands how best to use and maintain them. The specialist may need to adjust the implementation approach to accommodate changes in the business environment or address new emerging security threats.

    Training Clients on Best Practices for OT Security

    Finally, the specialist may provide training to employees and other stakeholders on the best practices for OT security. Training and raising awareness about OT security is crucial to ensure employees are well-informed about security policies and procedures and remain vigilant about any potential security incidents. The specialist can also help to develop training materials, including guidelines and checklists, to help employees understand their role in keeping the organization secure.

    In conclusion, an OT security specialist has several responsibilities, including assessing the client’s operational technology security risks, developing security strategies and roadmaps, and providing recommendations for improvement. The specialist must stay up to date with the latest security trends and technologies and collaborate with clients to ensure that security implementation plans are successful. Training employees on security best practices is also an essential aspect of the specialist’s role to help maintain a secure operational technology environment.
