ICS/IOT Security Assessments

Identify and remediate vulnerabilities in your ICS/OT system

Industrial automation systems, such as Industrial Control Systems (ICS) / Operational Technology (OT) and Supervisory Control and Data Acquisition (SCADA) systems pose unique security challenges, including securing network connections and rapidly patching vulnerabilities. Tangible Security offers comprehensive ICS/OT security assessment services. We assess security controls, architecture, remote access, network segmentation, physical security, and more. We identify vulnerabilities and deliver detailed reports that help you enhance security and ensure the resilience of your operations. Our assessment consists of four main components:

ICS/OT secure design and architecture assessment
Network vulnerability assessment and penetration testing to ensure proper segmentation
ICS/SCADA security assessment and control gap analysis
Reporting and recommendations

Identify and remediate vulnerabilities in your ICS/OT systems
Stay compliant and maintain operational continuity

ICS/OT Secure Design and Architecture Assessment

Our team of security experts collaborates with your management and technical teams to get an in-depth understanding of your system/network architecture design, focusing on documentation, information flow within the system, installation and administration procedures, operational methodology, and existing security safeguards. We then conduct a thorough assessment of your systems, including system architecture, access controls, auditing processes, configurations, and more. We then develop threat models to assess system security.

Assessment focus areas:

Alignment with best practices
System configurations
System architecture
Network architecture

Assessment focus areas:

External points of access
Externally accessible vulnerabilities
Network access controls
Network infrastructure

Network Vulnerability Assessment and Penetration Test

Leveraging insights from the design and architecture assessment, our team conducts comprehensive external and internal vulnerability assessments, including penetration tests where appropriate. The external assessment focuses on IT systems connected to the internet, and the internal assessment looks at operational technology, including ICS/SCADA networks and connected systems. We establish clear rules of engagement to ensure operational continuity and safety and ensure both a thorough security evaluation and appropriately sensitive handling of critical OT environments. Our approach identifies security risks and vulnerabilities in your networks and systems, evaluates associated risks, and develops a set of targeted strategies and recommendations to resolve issues and mitigate risks.

ICS/SCADA Security Assessment and Control Gap Analysis

Our team conducts an in-depth ICS/SCADA security assessment and control gap analysis, examining each component of the architecture individually and within the system context. We employ targeted activities including information-gathering, vulnerability testing, network topology analysis, and authentication/access control evaluations. If appropriate, we employ advanced techniques such as fuzzing to identify potential vulnerabilities in ICS devices and components. The ICS/SCADA security assessment and control gap analysis uses the findings from the earlier assessment phases to create a detailed analysis with a comprehensive mapping of existing and missing security controls across the entire ICS/SCADA environment. This approach allows us to uncover vulnerabilities and weaknesses that may have broader implications, identifying gaps in both operational and technical controls to provide a holistic view of your organization’s ICS/SCADA security posture.

Assessment focus areas:

Known vulnerabilities in components
Misconfiguration testing of components
Authentication and access controls

Report focus areas:

List of vulnerabilities by severity
Recommendations for remediation
Remediation validation testing

Reporting and Recommendations

Upon completion of the project, we produce a comprehensive technical report that highlights any discovered vulnerabilities and risks identified during the assessment, along with a set of findings and recommendations for remediation. The report is divided into separate sections for management and technical staff, ensuring the information is presented in a clear and concise manner. If requested, we can perform remediation validation testing within 90 days of report submission.
