NIS2, also known as the revised Directive on Security of Network and Information Systems, is a European Union legislation aimed at enhancing cybersecurity and ensuring the resilience of critical infrastructure and digital services. The NIS2 came into force on January 16, 2023. The new rules are likely to apply as of October 2024
Here are some important steps companies should consider to ensure compliance with NIS2:
Understand the scope and applicability: Familiarize yourself with the requirements and scope of NIS2 to determine if your organization falls within its purview. Assess whether you provide essential services or operate within critical infrastructure sectors identified in the directive.
Conduct a risk assessment: Identify and assess potential risks to the security of your network and information systems. Perform a comprehensive risk assessment, considering both internal and external threats, and evaluate the potential impact on your services and systems.
Develop a security policy: Establish a robust cybersecurity policy that outlines your organization’s commitment to NIS2 compliance. The policy should cover areas such as risk management, incident response, access controls, employee training, and supplier management.
Implement security measures: Deploy appropriate technical and organizational measures to protect your network and information systems. Consider implementing measures such as access controls, encryption, intrusion detection systems, security monitoring, and incident response plans.
Establish incident response capabilities: Develop an incident response plan that outlines the steps to be taken in the event of a cybersecurity incident. Define roles and responsibilities, establish communication channels, and conduct regular drills to ensure preparedness.
Maintain security awareness and training: Train your employees on cybersecurity best practices and ensure they are aware of their roles and responsibilities in protecting critical systems. Regularly update training materials to address emerging threats and promote a security-conscious culture within the organization.
Collaborate with relevant authorities: Cooperate with the appropriate national authorities and Computer Security Incident Response Teams (CSIRTs) as required by NIS2. Establish mechanisms for sharing information on incidents and cooperating in the resolution of cybersecurity issues.
Monitor and report incidents: Implement a robust incident monitoring and reporting system. Monitor your systems for potential security incidents, promptly investigate any anomalies, and report significant incidents to the relevant authorities, as required by NIS2.
Engage third-party suppliers: Evaluate the security practices of your suppliers and service providers to ensure they meet the necessary standards. Incorporate contractual obligations to comply with NIS2 requirements, including incident reporting and cooperation.
Regularly review and update security measures: Conduct periodic reviews of your security measures to ensure they remain effective and aligned with evolving threats and regulatory requirements. Stay informed about updates to NIS2 and adjust your practices accordingly.
