How can ISA/IEC62443 help with NIS2 compliance?
How can ISA/IEC62443 help with NIS2 compliance?
ISA/IEC 62443 is a set of standards developed specifically for cybersecurity.
We can set out how this standard can help us achieve the objective within our organizations, and meet the requirements of the NIS Directive2,
which we have already commented on in this series of news in several ways
Structure and Guidance for Implementing Security Measures
Risk and Vulnerability Assessment
ISA/IEC 62443-2-1:
It is no more than a set of guidelines for establishing an industrial cyber security program.
This includes risk identification and assessment, which is crucial to meeting the risk assessment requirements of the NIS2.
Technical and Safety Management Requirements
- ISA/IEC 62443-3-3: Defines technical security requirements for industrial automation and control systems, addressing access controls, system integrity, confidentiality, and availability.
- ISA/IEC 62443-2-4: Establishes security requirements for engineering and support service providers, ensuring that these services are performed in a secure manner.
Network Segmentation and Access Control
Network Segmentation
- ISA/IEC 62443-3-2: Provides a methodology for network segmentation and the creation of security zones and ducts, which helps limit lateral movement of threats within the OT network.
Access Control
- ISA/IEC 62443-3-3: Includes guidelines on identity management and role-based access control(RBAC).
- ensuring that only authorized personnel can access critical systems, aligning with NIS2 access control requirements.
Incident monitoring and response
Continuous Monitoring
- ISA/IEC 62443-3-3: Although it has a very ugly, distant comet-like name, it actually describes the requirements for continuous system security monitoring,
- including intrusion detection
- Incident response, which is fundamental to incident reporting under NIS2.
Incident Management
- ISA/IEC 62443-2-1: Provides guidance for the establishment of incident response procedures, including incident detection, analysis, response and recovery.
- In doing so, we help organizations to facilitate their ability to meet the requirements of :
- Notifications
- NIS2 Incident Management.
- In doing so, we help organizations to facilitate their ability to meet the requirements of :
TECHNOLOGY AND CYBERSECURITY EXPERTS
On-Site technicians, remote support 24x7 | 11x5, migrations, cybersecurity solutions, secure communications auditing, cloud PBX, wifi, videoconferencing, network electronics...
Training and awareness
- Staff Training
- ISA/IEC 62443-2-1: Recommends the implementation of cybersecurity training and awareness programs for personnel,
- ensuring that all employees understand their role in the protection of industrial control systems.
Compliance and Audit
Audits and Security Review
- ISA/IEC 62443-2-4: Provides guidelines for conducting periodic safety audits and reviews.
Collaboration and Best Practices
Information Exchange
- ISA/IEC 62443-2-1: Promotes collaboration and information sharing on cyber threats and best practices among organizations and stakeholders, which is essential to meet the cooperation requirements of NIS2.
Conclusion
ISA/IEC 62443 provides a detailed and specific framework for cyber security.
This framework covers industrial control systems and OT, addressing many of the key requirements of the NIS2 Directive.
By implementing the practices and guidelines of ISA/IEC 62443, organizations can
- significantly improve your safety posture
- ensure compliance with NIS2 and
- effectively protect your industrial operations against cyber threats.
