Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments are increasingly targeted by sophisticated cyberattacks. Critical sectors such as manufacturing, energy, water, transportation, and smart cities rely heavily on ICS/OT infrastructure in Malaysia. A breach in these systems can lead to operational disruptions, financial loss, safety hazards, and regulatory non-compliance. IEC 62443 provides a globally recognized framework for ICS/OT cybersecurity, including risk assessment, system hardening, access control, and secure lifecycle management. In Malaysia, aligning with IEC 62443 ensures operational resilience and regulatory compliance.
Cyberintelsys, a CREST accredited cybersecurity firm, delivers comprehensive Vulnerability Assessment (VA) and Penetration Testing (PT) services for IEC 62443 environments. Our services help industrial organizations identify, prioritize, and mitigate vulnerabilities in ICS/OT systems, enhancing cybersecurity posture, compliance, and operational continuity.
Importance of VA/PT for IEC 62443 Compliance
ICS/OT systems differ from traditional IT networks. They often include legacy devices, proprietary protocols, and high-availability systems that cannot tolerate downtime. Vulnerabilities can arise in PLCs, HMIs, SCADA servers, network controllers, and communication protocols.
VA/PT is essential because:
Identify critical vulnerabilities in industrial control systems.
Demonstrate regulatory alignment with IEC 62443 standards.
Ensure operational continuity and process safety.
Strengthen ICS cybersecurity resilience.
Build stakeholder confidence and compliance readiness.
