Information Security
Information security is about protecting an organization’s information—whether digital or physical—against unauthorized access, alteration, or loss. It is based on three fundamental principles: confidentiality, integrity, and availability (the CIA triad). With stricter regulations such as NIS2, information security has become a clear management and board issue.
The Basics of Information Security
A systematic approach to information security is based on three fundamental objectives:
- Confidentiality: Information should only be available to those who are entitled to it.
- Accuracy: Information must be accurate and protected against unauthorized modification.
- Accessibility: Information should be available when it is needed.
- Classification: This work should be carried out systematically, often with the support of a management system such as ISO 27001.
Common Challenges in Information Security
- Viewed as an IT issue: Information security is mistakenly viewed as merely a technical issue, rather than a business and management issue.
- Regulatory pressure: Requirements from NIS2 and GDPR compliance raises the bar significantly.
- The Human Factor: Most incidents are due to human error rather than technical failures.
- Skills Shortage: There is an acute shortage of qualified security professionals in the market.
How an Interim CIO Can Strengthen Security
Information Security supports NIS2 efforts and the roles of security managers and CIOs within our network.
- Current Situation Analysis: One interim CIO identifies where the organization's security is lacking and what needs to be prioritized.
- Establishes governance: Establishes a systematic approach to safety and the processes required by regulations.
- Raises awareness: Experience in embedding security throughout the entire organization, not just in the IT department.
- Immediate capacity: Interim Search's process ensures that you have the right talent in place within 48 hours.
Frequently Asked Questions About Information Security
What is the difference between information security and cybersecurity?
Information security is the broader concept and encompasses the protection of all information, including physical and organizational aspects. Cybersecurity is a subset that specifically concerns the protection of digital systems, networks, and data against IT-related threats. Cybersecurity is thus an important part of—but not the entirety of—information security.
What is ISO 27001?
ISO 27001 is an international standard for information security management systems (ISMS). It provides a framework for systematically identifying risks and implementing appropriate security measures. Certification under this standard is often used to demonstrate to customers and regulatory authorities that the organization takes a structured approach to information security.
How is information security related to NIS2 and the GDPR?
Both NIS2 and the GDPR set specific requirements that necessitate effective information security practices. The GDPR focuses on the protection of personal data, while NIS2 sets broader requirements for cybersecurity and incident reporting for critical infrastructure sectors. A systematic approach to security is the foundation for complying with both.
