This blog dives into the concept of cybersecurity, discussing the key components that are relevant for organizations. Furthermore, an overview of the most important frameworks and regulatory requirements – NIST CSF 2.0, NIS2, DORA, ISO27001, and BSI baseline protection – provides insights into how to fortify defenses against the ever-evolving landscape of cyber threats.

Cybersecurity encompasses a broad range of technologies, processes, and practices designed to protect networks, data, applications, and devices from attack, damage, or unauthorized access. At its core, cybersecurity aims to ensure the confidentiality, integrity, and availability of information.

A successful cybersecurity strategy involves the following three layers of protection that all complement one another:

• People: All users must adhere to basic security principles such as choosing strong passwords, being wary of attachments in email, and backing up data regularly.
• Processes: This includes but is not limited to organizational policies and processes that outline how to handle and protect sensitive information and how to respond to cybersecurity incidents.
• Technology: This addresses the software and hardware defenses that protect endpoint devices, networks and the cloud.

Cybersecurity is a critical component within the broader fields of IT security and information security, each addressing different aspects of protection in the digital age.

• Information Security: Encompasses the protection of both digital and non-digital information. It addresses the confidentiality, integrity, and availability of all forms of data – electronic, printed, or else – and ensures that data is accessible only to those authorized to access it.
• IT Security: As a subset of information-security, IT security focuses specifically on the digital protection of stored and processed information. It involves safeguarding data from unauthorized access and threats through technological means.
• Cybersecurity: Refers to the protection of systems, networks, and applications from digital attacks. It extends the concepts of IT-security to the entire cyberspace, including all cloud-connected systems and the broader digital environments.

Together, these areas create a comprehensive framework for protecting all forms of data and managing the wide array of risks associated with information in the digital age.

In the realm of cybersecurity, various frameworks and regulations have been established to guide organizations in enhancing their security measures. These frameworks and regulations provide structured approaches to managing cybersecurity risks, complying with legal requirements, and implementing best practices across industries. Below is a summary of some of the key standards and regulatory requirements.

These regulations and standards are crucial because they provide:

• Structured Approach: Helping businesses manage cybersecurity risks systematically and efficiently.
• Compliance: Assisting organizations in meeting legal and regulatory requirements.
• Trust: Building trust inside and outside the organization by demonstrating a commitment to cybersecurity.

By committing to cybersecurity, organizations can not only protect themselves from the impacts of attacks but also gain a competitive advantage.

NIS2 seeks to address the increasing number of cyber threats and incidents by establishing a high common level of security for networks and information systems across the EU. It is an update to the European Union’s Directive on security of network and information systems, aiming to bolster the level of cybersecurity across the EU by expanding the scope of its predecessor, NIS1, to include a wider range of sectors and digital services.

NIS2 applies to a broader array of sectors compared to the original directive, impacting medium and large organizations across essential and important sectors such as:

• Essential Services: Energy, transport, banking, digital infrastructure, and healthcare.
• Important Services: Postal and courier services, waste management, manufacture and supply of water, and food production.
• Digital Services: Including cloud computing services and online marketplaces.

This wider scope ensures that more entities are maintaining robust cybersecurity practices.

The NIS2 directive outlines comprehensive requirements aimed at strengthening cybersecurity across various sectors:

• Risk Management: Development of concepts for risk analysis, assessment and proper management measures.
• Incident Handling: Processes for managing and mitigating cybersecurity incidents effectively.
• Business Continuity Management: Includes backup handling, recovery from disruptions, and comprehensive crisis management.
• Supply Chain Security: Enhancing the security aspects of relationships and dependencies between a business and their direct suppliers and service providers.
• Access Control and Asset Management: Security measures that include trainings, cryptography, need-to-know, and segregation of duties principles.

These legal requirements are designed to ensure that entities not only comply with the highest security standards but also maintain a proactive posture against the evolving landscape of cyber threats.

The Digital Operational Resilience Act (DORA) is a new regulatory framework introduced by the European Union to enhance the operational resilience of its financial sector. DORA aims to ensure that all entities in the financial system have the necessary safeguards to mitigate cyber risks and maintain their operations through various types of ICT disruptions. DORA provides significant extensions and more precise requirements than the NIS2 directive, particularly increasing the demands regarding the financial sector and their IT service providers.

DORA adopts a holistic approach, targeting a wide spectrum of financial entities within its regulatory scope.

• Financial Institutions: Extending its scope from banks and insurance companies, which are already familiar with EBA/EIOPA guidelines for ICT security and outsourcing, to trading venues, institutions for occupational retirement provision, crypto service providers, insurance intermediaries, and numerous other financial firms.
• ICT Providers: Additionally, IT service providers that serve financial institutions, may now fall under DORA, if they are classified as “critical ICT providers”. The criteria for this classification, to be further specified by the European Supervisory Authorities (ESAs), primarily depend on how critical the services provided are to the financial market, the extent of dependency on the ICT provider, and the ease with which they can be replaced.

This extensive scope is crucial as it ensures that the entire financial ecosystem, including its supporting ICT infrastructure, adheres to uniform resilience standards, thereby significantly reducing systemic risk and enhancing the overall stability of financial markets across Europe.

To enhance the cybersecurity posture of the financial sector across the European Union, DORAis built on the following core pillars:

• ICT Risk Management: Development of a comprehensive information security concept and framework, including the assessment of existing resilience, and establishment of detective security systems.
• ICT Incident Reporting: Implementation of early warning indicators and means for incident classification, along with handling, classification and handling of incidents.
• Operational Resilience Testing: Establish incident response plans, conduct regular testing and assessments (e.g. end-to-end, performance, penetration, or compatibility), and provide employee training.
• ICT Third-Party Risk: Assessment of the extent, complexity, and relevance of ICT-related dependencies on service providers, including contractual agreements and their documentation.
• Information & Intelligence Sharing: Exchange cyber threat information within trusted communities to boost security, ensuring details are protected and compliant with confidentiality and competition guidelines.

These pillars collectively strengthen the infrastructure of the financial sector, ensuring it can resist and recover from operational disruptions linked to ICT issues, thus maintaining market integrity and overall trust.

The National Institute of Standards and Technology (NIST) Cybersecurity Framework offers a structured and scalable approach to managing cybersecurity risks. The latest iteration, the NIST CSF 2.0, builds on proven practices to offer an even more robust framework.
