How HexaPrime help you with OT Security!

OT environments require a different security approach from traditional IT. Production availability, legacy technologies, proprietary protocols, safety requirements, and long equipment lifecycles must all be considered before conducting security assessments. Our methodology combines safe technical assessment, architecture analysis, configuration review, vulnerability identification, and security-control validation to provide a holistic view of the OT security posture.

FAQs
Frequently Asked Questions
What is an OT Security Assessment?

An OT Security Assessment evaluates the cybersecurity posture of systems responsible for physical and industrial operations. It identifies vulnerabilities, architecture weaknesses, configuration issues, security-control gaps, and potential attack paths that could affect the confidentiality, integrity, availability, or safety of operational environments.

How is an OT Security Assessment different from a traditional IT security assessment?

OT assessments place greater emphasis on operational availability, process safety, legacy systems, industrial protocols, equipment lifecycle, and production impact. Testing techniques that may be acceptable in traditional IT environments may create unacceptable risks in OT and are therefore carefully controlled.

Will the assessment disrupt our production environment?

The assessment is designed to minimize operational risk. Activities are planned according to agreed rules of engagement, and intrusive testing is avoided on sensitive production systems unless specifically authorized and determined to be safe.

What types of OT systems can be assessed?

Depending on the environment and agreed scope, assessments can cover SCADA systems, DCS environments, PLCs, RTUs, HMIs, engineering workstations, historians, OT servers, industrial network devices, firewalls, IIoT devices, remote-access systems, and supporting security technologies.

Do you perform vulnerability scanning in live OT environments?

Where technically and operationally appropriate, vulnerability assessment techniques may be used. The exact approach depends on asset sensitivity, vendor restrictions, operational requirements, and customer approval. Passive or non-intrusive techniques may be preferred for highly sensitive systems.

Do you assess IT-to-OT connectivity?

Yes. The architecture review can assess IT/OT trust boundaries, industrial DMZs, firewall rules, remote access, vendor connectivity, network segmentation, and communication flows that could provide potential pathways into critical OT environments.

Do you map findings to MITRE ATT&CK for ICS?

Yes. Where relevant, findings and attack scenarios can be mapped to MITRE ATT&CK for ICS tactics and techniques, helping security teams understand the relationship between identified weaknesses and known adversary behaviors.

Will we receive remediation recommendations?

Yes. Each significant finding includes practical remediation guidance. A prioritized remediation roadmap is also provided to help organizations determine which security improvements should be addressed immediately, in the short term, and as part of longer-term OT security initiatives.

Can the assessment evaluate our existing OT security tools?

Yes. The assessment can evaluate whether deployed security technologies are appropriately positioned, configured, integrated, and providing sufficient visibility across the OT environment. This can include OT firewalls, IDS/NDR, SIEM, endpoint security, remote-access solutions, and other monitoring or protection technologies.

Which standards and frameworks can the assessment align with?

Depending on customer requirements, the assessment methodology and recommendations can be aligned with recognized OT cybersecurity practices and frameworks such as IEC 62443, NIST Cybersecurity Framework, NIST SP 800-82, MITRE ATT&CK for ICS, and relevant vendor security guidance.
