compliance Perform
- Plan, scope, and conduct
internal IT security audits for 8–12 manufacturing clients annually.
- Assess IT environments
(Active Directory, firewalls, patch management, privileged access, MFA,
logging/SIEM).
- Evaluate OT/IoT security
where IT systems connect to production networks (PLCs, HMIs, SCADA,
historians).
- Review compliance with ISO
27001, NIST CSF, IEC 62443-2-1, and GDPR (where applicable).
- Perform audit procedures
including:
- Control testing (technical
& administrative)
- Vulnerability assessment
(non-intrusive)
- Configuration reviews
(switches, firewalls, servers)
- Access control & user
entitlement reviews
- Backup & disaster
recovery validation
- Identify gaps in network
segmentation between office IT and shop-floor OT.
Reporting
& Remediation
- Document findings with clear
risk ratings (Critical, High, Medium, Low).
- Provide
manufacturing-specific recommendations (e.g., “air gap backup recovery,”
“replace unsupported Windows 7 on HMI”).
- Present audit reports to
plant managers and IT leadership.
- Track remediation progress
and perform limited validation re-audits.
Compliance
& Standards
- Map audit findings to
regulatory requirements (e.g., CMMC, NIS2 if applicable).
- Support clients during
external audits or insurance cyber assessments.
Collaboration
- Work with client maintenance
and controls engineers (non-security personnel) to explain risks without
jargon.
- Escalate critical findings
(e.g., ransomware exposure via exposed RDP on a production server)
immediately.

Experience
- 3–5 years in IT security
auditing or security consulting – with at least 1 year directly auditing

- Familiarity with industrial
protocols (Modbus, PROFINET, OPC UA) – not for deep testing, but to
understand risk context.
