Get an overview of NIS2

The EU member states have adopted a new version of the Network and Information Security Directive (NIS). The NIS2 Directive expands EU requirements for companies’ and organizations’ approaches to risk management, security implementation, and preparedness for handling cyberattacks. The deadline for implementation is set for July 1, 2025.

The purpose of NIS2 is to strengthen cybersecurity and make companies more resilient to cyber threats across the EU. This means the requirements have been tightened for several sectors, where organizations must address risk management, control, reporting, and supervision.

The NIS2 Directive applies to critical infrastructure companies, which are defined as those with a crucial role in society. Key details include:

  • Adoption: On November 10, 2022, the European Parliament adopted the NIS2 Directive.
  • Purpose: To ensure a high common level of network and information security in Europe.
  • Target group: Companies and organizations with a critical role in society.
  • Changes from the previous NIS Directive: Broader sector coverage.
  • New rules:
    • Possibility of fines for non-compliance.
    • Critical companies must implement comprehensive security protocols to protect their digital infrastructure.
    • The NIS2 Directive strengthens oversight to ensure compliance with security requirements.
    • Management is held directly accountable for legal violations.
  • Objective: To create incentives for leaders to take NIS2 seriously and ensure adherence to the regulations.

Analysis of Your Network

Why a Network Analysis is Important
A thorough analysis of your network is crucial for identifying vulnerabilities, improving performance, and ensuring that your infrastructure is robust enough to withstand cyber threats while supporting your business needs. A network analysis provides insights into the strengths and weaknesses of your network, enabling informed decisions about upgrades, security measures, and future investments.

A network analysis is an essential tool for any organization aiming to ensure the stability, security, and efficiency of its network. By conducting an analysis, you can enhance performance, protect against cyber threats, and make well-informed decisions for the future. The result is a network that is secure, scalable, and fully equipped to meet the organization’s needs.

Asset Management

Asset Management involves identifying, tracking, and monitoring all assets within a network, including hardware and software. It is critical for security in OT (Operational Technology) environments. Having a complete overview of all assets allows for better protection against potential cyber threats and ensures operational stability in critical systems.

In Summary
Asset Management is a core function of OT security and risk management. By maintaining a clear picture of all assets, overall security is strengthened, and the organization achieves greater resilience against potential cyber threats.

Disaster Recovery Plan

A Disaster Recovery Plan (DRP) is a structured, documented strategy that outlines how an organization should respond to and recover its critical IT and OT systems following a major disruption or disaster, such as a cyberattack, natural disaster, or system failure. The plan includes procedures for backup, data restoration, system recovery, and communication, helping to reduce downtime and minimize financial losses.

IEC 62443: A Standard for Security in OT Systems and Networks

IEC 62443 is an internationally recognized standard for cybersecurity in Industrial Automation and Control Systems (IACS). The standard is designed to protect OT systems and OT networks (Operational Technology) from cyber threats and includes a range of requirements and guidelines to help organizations secure their industrial systems, such as SCADA, PLCs, and other critical control devices.

Strengthen Security on Your OT Network

Why is it important to enhance the security of your OT network? Cyberattacks targeting OT companies have been on the rise, especially in critical infrastructure and industrial sectors, as these areas often rely on OT networks to manage vital processes.

Significant reports and studies have documented attacks on OT companies across industries such as energy, manufacturing, transportation, water supply, and healthcare. Here are some well-known examples and statistical trends illustrating the scale of the issue. These statistics demonstrate that OT networks are particularly vulnerable, and attacks can have serious consequences for operational continuity and finances. The need to strengthen OT security through network segmentation, secure firewalls, access control, continuous monitoring, and regular system and software updates is therefore crucial.

A study by Gartner revealed that attacks on OT systems increased by over 40% in 2022, and it is predicted that 30% of OT devices will be affected by cyber threats in the next five years.

Typical Types of Hacker Attacks

In a digitalized world, cyberattacks pose a serious threat to businesses. Hackers constantly develop new methods to steal data and cripple critical functions. No company is immune, and the consequences can include financial losses, loss of customer trust, and reputational damage. Many smaller businesses close within six months of a major attack. Understanding the most common cyberattacks is essential for protecting your business effectively.
