We help manufacturers implement the processes and technical measures required to develop secure products.<\/p>

Secure Development Lifecycle (IEC 62443-4-1)<\/strong><\/p>

We support the implementation of the following practices:<\/p>

  1. Security Management<\/li>
  2. Security Requirements, including security concepts, threat modelling, threat analysis and risk assessment (TARA)<\/li>
  3. Secure by Design<\/li>
  4. Secure Implementation<\/li>
  5. Security Verification and Validation<\/li>
  6. Vulnerability and Security Incident Management<\/li>
  7. Security Update Management<\/li>
  8. Security Guidelines and User Documentation<\/li><\/ol>

    Security Requirements for Components (IEC 62443-4-2)<\/strong><\/p>

    We help organizations to:<\/p>

    • assess existing products,<\/li>
    • define the target Security Level Capability (SL-C),<\/li>
    • identify missing security functions,<\/li>
    • prepare supporting evidence for certification.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/section>\n\t\t

      Design and Implementation of Secure Industrial Systems<\/span><\/strong><\/p>

      System integrators combine multiple products and technologies into a single functional system. As a result, cybersecurity is not only a characteristic of individual products, but of the entire system.<\/p>

      We help organizations to:<\/p>

      • define a security architecture,<\/li>
      • identify security zones and conduits,<\/li>
      • define\u00a0cyber-security requirements,<\/li>
      • assess risks at the system level,<\/li>
      • evaluate compliance with IEC 62443 requirements,<\/li>

        Risk Assessment and Security Levels.<\/span><\/strong><\/p>

        IEC 62443 requires organizations to understand cybersecurity risks and determine the appropriate level of protection. We help organizations to:<\/p>

        • identify assets,<\/li>
        • analyze threats,<\/li>
        • model potential attack scenarios,<\/li>
        • assess cybersecurity risks,<\/li>
        • define the target and achieved Security Level (SL-T, SL-A).<\/li><\/ul>
