What is NIS2?

NIS2 stands for the second iteration of the EU’s Network and Information Systems Directive. It is a set of cybersecurity regulations designed to improve the resilience and security of network and information systems across the EU.

NIS2 requires organizations that provide essential services, such as energy, finance, healthcare, and transportation, to implement robust cybersecurity measures and report certain types of security incidents.

The directive also establishes a cooperation framework between EU member states to share information and coordinate response to cyber incidents.

Overall, NIS2 aims to improve the protection of critical infrastructure and enhance the cybersecurity posture of the EU.

The key elements are:

  • Cybersecurity law for the EU.
  • Higher protection standards will be required.
  • More sectors are under its scope.
  • Reporting incidents will now be mandatory.
  • Increased supervisory powers are granted.
  • EU-wide harmonization of regulations.

What steps can you take to achieve NIS2 compliance?

1. Identify your critical infrastructure

Identifying your critical infrastructure is essential to protect your most valuable assets.

  • Determine which assets are critical to your business operations.
  • Assess the risks to those critical assets.
  • Use automated threat detection to identify potential risks and vulnerabilities in real-time.

Vectra AI can help you identify your critical infrastructure by continuously monitoring your network and cloud environments, providing real-time visibility into the security posture of your entire infrastructure. Learn more about the Vectra AI Threat Detection and Response platform.

2. Develop an incident response plan

Developing an incident response plan is crucial for minimizing the impact of a security breach.

  • Define roles and responsibilities for responding to security incidents.

  • Use machine learning algorithms to quickly identify and respond to threats in real-time.

Vectra AI can help you monitor your network for anomalies by providing industry leading Attack Signal Intelligence™, automated incident response capabilities and behavioral analytics to identify anomalies that may indicate a security breach. Vectra can provide coverage for networks, cloud, SaaS (software as a service) and identity environments. With native integrations to leading EDR (Endpoint Detection and Response) providers Vectra AI can provide coverage for all five attack surfaces. Vectra AI Managed Detection and Response services are available to help organizations who lack the required resources and skills to deliver a comprehensive internal service.

7. Develop a disaster recovery plan

Developing a disaster recovery plan is crucial for minimizing the impact of a security breach and ensuring that your business can continue to operate in the event of a security incident.

  • Define recovery time objectives (RTOs) and recovery point objectives (RPOs) for critical systems.
  • Implement data backup and restoration procedures to ensure that critical data can be recovered in the event of a security incident.
  • Test your disaster recovery plan regularly to ensure that it is effective and up to date.

Vectra AI can help disaster recovery by providing automated incident response capabilities and forensic analysis to help you quickly detect and respond to security incidents. Take a tour. How Vectra AI protects against ransomware

Timeline to implement NIS2

The timeline to implement NIS2 can vary depending on the size and complexity of your organization’s network and infrastructure, as well as the level of maturity of your existing cybersecurity program. However, in general, it is recommended to start planning for NIS2 implementation as soon as possible to ensure that your organization is prepared for the evolving threat landscape. Here is a potential timeline for implementing NIS2:

1. Assessment and planning (3-6 months)

This phase involves conducting a comprehensive assessment of your organization’s current security posture to identify gaps and areas of improvement. This can include identifying critical assets, reviewing policies and procedures and conducting vulnerability assessments and penetration testing. Based on the findings, you can develop a roadmap and timeline for NIS2 implementation.

2. Implementation (6-12 months)

This phase involves implementing the necessary technical and organizational measures to comply with NIS2. This can include implementing security controls and tools, such as intrusion detection and prevention systems, firewalls, and SIEM (Security Information and Event Management) solutions, as well as establishing processes for incident response, vulnerability management and security awareness training.
