Performing PLC Firmware Security Analysis

When to Use

• When assessing PLC security as part of an IEC 62443 component security evaluation (IEC 62443-4-2)
• When validating firmware integrity after a suspected compromise or supply chain attack
• When evaluating the security of a new PLC platform before deployment in critical infrastructure
• When performing vulnerability research on industrial control system devices in an authorized lab
• When responding to an incident where PLC logic or firmware tampering is suspected

Do not use on live production PLCs without explicit authorization and safety controls in place. Firmware extraction and analysis should be performed on lab devices or offline backups. Never upload PLC firmware to public analysis services. See performing-ics-penetration-testing for authorized live testing procedures.
