Ensure compliance with regulations—don’t let your global customers turn away from your organization! In an era of globalization and highly competitive markets, the world demands more automation, which increases the risk of cyber threats. The IEC 62443 standard is critical for protecting industrial automation and control systems from security breaches. If an attack succeeds, unauthorized actors could access sensitive data, disrupt or shut down the network, and even cause industrial systems to malfunction. Therefore, meeting cybersecurity requirements and implementing IEC 62443 is essential today. The IEC 62443 standard is a series of standards for cybersecurity management controls that leverage technical reports and related information to define the implementation process for secure Industrial Automation and Control Systems (IACS).

The IEC 62443 standard is designed to prevent cybersecurity vulnerabilities and attacks targeting asset owners. In 2002, the International Society of Automation (ISA) published a document titled ISA-99, which contained the information needed by companies operating in the automation sector to protect themselves against cyber threats.

IACS is synonymous with operational technology (OT), a technology that interfaces with an operational process. In this context, the term is used to distinguish an IACS from an information technology (IT) device intended to receive and transmit information. Examples of IACS include industrial devices such as programmable logic controllers (PLCs), human-machine interfaces (HMIs), and supervisory control and data acquisition (SCADA) systems

Would you like to implement IEC 62443 Security Levels (SL)?

IEC 62443 Security Levels are security levels used to assess cybersecurity risks. These security levels help you understand how best to address risks. There are five security level values ranging from 0 to 4. SL 0 represents the minimum risk level, while SL 4 represents the maximum risk level. This means that SL 4 has stricter compliance requirements than SL 0.

• Security Level 0 — No special requirements or security protection is required.
• Security Level 1 — Protection against accidental or unintentional violations.
• Security Level 2 — Protection against intentional breaches can be provided using simple tools against the following:
• Security Level 3 — Protection against intentional breaches using advanced tools, including the following:
  • Moderate resources
  • IACS-specific skills
  • Moderate motivation
• Security Level 4 — Protection against deliberate attacks using advanced tools with the following:
  • Extended resources
  • IACS-specific capabilities
  • High motivation

Why and How Should You Comply with the IEC 62443 Standard?

The IEC 62443 standard provides guidance on how to ensure the secure development of an IACS. The most important part of complying with the IEC 62443 standard is the use of a static code analyzer. A static code analyzer automatically identifies security vulnerabilities and defects as you write code. Additionally, you can apply a coding standard to ensure your software is compliant and reliable. The standard requires the use of a static code analyzer to implement secure coding practices. Securesys will assist you with both code security and compliance.

Compliance with the IEC 62443 standard serves as a guarantee for both the security of OT data shared with IT and the entire manufacturing sector. Thanks to this standard, it is possible to prevent potential infections caused by compromised data. Looking to the future, if we do not implement adequate security measures against cyberattacks for industrial automation control systems, ensuring the security of industrial products will not be possible. Therefore, we all need to be aware of this scenario.
