Vendor Evaluation and Selection Checklist
Securing Industrial Environments Against Removable Media Threats
In industrial environments, cybersecurity threats rarely begin with sophisticated remote attacks. In many cases, the entry point is something much simpler-removable media. USB drives, portable storage devices, CDs, and SD cards are still widely used across industrial sites for firmware updates, configuration transfers, and maintenance activities. While these tools enable operational efficiency, they also introduce significant cybersecurity risks into Operational Technology (OT) environments.
Even highly segmented or air-gapped industrial networks are not immune. Malware can easily enter through removable media used by contractors, engineers, or maintenance teams. Several well-known industrial cyber incidents demonstrated how adversaries used infected media as an initial access vector to compromise Industrial Control Systems (ICS), SCADA networks, and safety systems.
To help OT security teams make informed decisions, Shieldworkz has developed the Removable Media Scan Solution Vendor Evaluation and Selection Checklist. This practical checklist helps organizations assess whether a removable media security solution is truly suitable for industrial environments-not just traditional IT networks.
The checklist is designed for OT security practitioners, asset owners, plant operators, and procurement teams who need a structured framework to evaluate solutions before deploying them across critical infrastructure environments.
Why this checklist matters
Industrial environments have very different requirements from enterprise IT networks. Many facilities still rely on legacy operating systems, specialized industrial protocols, and isolated network architectures that cannot support conventional IT security tools. Deploying the wrong removable media scanning solution can introduce new operational risks. For example, solutions that require internet connectivity, generate unexpected network traffic, or attempt to modify files during scanning could disrupt industrial processes or trigger alarms in sensitive environments.
This checklist addresses those challenges by providing a structured evaluation framework based on widely recognized industrial cybersecurity practices and standards such as IEC 62443 and industrial security best practices.
The evaluation criteria are organized across seven key domains, including:
OT environment compatibility
Malware detection and scanning capabilities
Operational workflow and usability
Threat intelligence and signature updates
Logging and reporting capabilities
Security hardening of the scanning solution
Vendor maturity and long-term support
Each criterion is categorized based on priority levels such as Mandatory, Recommended, Preferred, or Situational, allowing decision-makers to identify which requirements are non-negotiable for safe deployment in OT environments.
Why it is important to download this Checklist
Selecting a removable media scanning solution for an industrial environment is not simply a technology decision-it is a risk management decision that can impact operational safety, production continuity, and regulatory compliance.
This checklist helps organizations:
Make informed procurement decisions: Procurement teams often evaluate security tools using IT-centric criteria. This checklist ensures the evaluation focuses on OT-specific risks and operational requirements.
Reduce the risk of introducing unsafe security tools: Some solutions designed for enterprise environments may create compatibility issues in ICS environments. The checklist helps ensure the solution aligns with industrial operational constraints.
Strengthen protection against removable media threats: By validating detection capabilities such as multi-engine scanning, deep file inspection, and heuristic analysis, organizations can better defend against sophisticated malware threats.
Support regulatory and compliance requirements: Industrial organizations are increasingly required to demonstrate cybersecurity controls aligned with standards and regulatory frameworks. This checklist helps create documented evidence for internal and external audits.
Standardize vendor evaluation processes: Instead of ad-hoc comparisons, teams can use this checklist to conduct consistent and repeatable evaluations across multiple vendors.
Key Takeaways from the Checklist
The Removable Media Scan Solution Vendor Evaluation and Selection Checklist highlights several critical considerations that organizations should not overlook when evaluating scanning solutions for industrial networks.
OT Compatibility Is the First Priority: Industrial systems often operate in air-gapped or isolated environments where internet connectivity is restricted. Any scanning solution must function fully offline and must not introduce network dependencies that could disrupt OT security perimeters.
Detection Must Go Beyond Traditional Antivirus: Industrial threats increasingly involve custom malware targeting OT systems. Effective removable media scanning solutions must include capabilities such as multi-engine scanning, behavioral analysis, and deep inspection of file contents rather than relying solely on basic signature detection.
Operational Workflow Must Be Practical: Security controls that slow down operations are frequently bypassed by users. The checklist emphasizes usability features such as automated scanning on media insertion, clear operator feedback, and fast scan times to ensure that security processes integrate smoothly with operational workflows.
Logging and Auditability Are Critical: Industrial security programs require strong logging and reporting capabilities. Detailed scan logs help support incident investigations, regulatory audits, and compliance reporting.
The Scanner Itself Must Be Secure: The removable media scanner should be treated as a critical security asset. Hardened operating systems, secure boot mechanisms, restricted ports, and encrypted storage help ensure that the scanning system itself cannot become a new attack vector.
Vendor Expertise Matters: Industrial cybersecurity solutions require deep understanding of OT environments. Vendors must demonstrate proven experience supporting industrial sectors and maintaining long-term product support cycles that align with OT infrastructure lifecycles.
