The Three Pillars of Data Security

Organizations are increasingly faced with the challenge of protecting confidential and/or sensitive personal data. It is crucial to ensure this information doesn’t end up “in the wrong hands.” Hugo Gerritse (Information Security & Quality Consultant) observes that many organizations struggle to translate security requirements into practical, everyday actions.

“For organizations, it is a complex task to map out where personal data is processed, who has access to sensitive information, and whether systems are secure enough. Meeting these requirements depends largely on the awareness of employees and the external parties an organization collaborates with. Do they possess the right expertise, and are external parties, for example, certified? These are just some of the questions that need to be addressed,” explains Hugo.

But how can you ensure you implement the appropriate control measures? And what do you expect from customers, suppliers, and other external parties to meet these standards? In this blog, we’ll explain three areas where you can enhance the security and quality of data within your organization:

1. Physical security measures
2. Organizational security measures
3. Technical security measures

Physical security measures at and around your location(s)

Our physical and digital environments are constantly evolving. Developments occur rapidly, and changing regulations (such as the GDPR) also pose challenges. How is your access policy organized? Does your security management system still align with it? Are hardware components such as cameras, intrusion systems, or locks functioning properly?

The right mix of personnel, structural, and electronic measures forms the foundation of physical security measures and directly impacts the safety of your data. Some examples that can enhance security at and around your location(s) include:

• Authorizing visitors and employees through an access control system.
• Installing an anti-intrusion system that covers all access points.
• Implementing 24/7 camera surveillance at the access points of your location(s).
• Considering whether 24/7 on-site surveillance is applicable.

Organizational Security Measures: Awareness is Essential

Physical security measures are only as effective as the organizational agreements established with employees, as well as with customers and suppliers. It is therefore crucial that they also meet your standards for security and quality, with clear agreements that are properly documented. External parties with various certifications (e.g., ISO) can help fulfill these requirements. Examples of organizational measures to safeguard your data include:

• Obtaining a Certificate of Good Conduct.
• Conducting awareness training in privacy and information security, such as social engineering tests, phishing simulations, and workshops.
• Setting up a formal approval process for access to spaces or, for instance, client servers.
• Applying project management methodologies that include risk assessments according to ISO 27001.
• Certification for information security: ISO 27001.

Certification for information security: ISO 27001.

ISO 27001 is the international standard for information security. The certification demonstrates that an organization has implemented necessary precautions to protect sensitive information from unauthorized access or modification. This standard focuses not only on process and procedure setup but also on adherence, monitoring, evaluation, and continuous improvement. It is not a one-time achievement but an ongoing process of safeguarding and quality enhancement. Key characteristics of ISO 27001 include:

• Demonstrating the importance of information security at all organizational levels.
• Reinforcing the confidence of customers, employees, trading partners, and stakeholders that information and IT systems are handled responsibly.
• Supporting compliance with relevant laws and regulations, such as the GDPR, which mandates the secure handling of personal data.
• Reducing risks and incidents through well-designed and effectively executed data security processes.

Technical Security Measures for Process Continuity

IT measures are also crucial to ensuring the continuity of processes and protecting your data. These upgrades are essential to maintain smooth and secure business operations, ensuring the availability, continuity, and security of your locations now and in the future. Additionally, it’s important to establish measures for data management and storage. Where is your data stored? Does it comply with legal requirements and align with your security needs? Examples of technical security measures include:

• Accessing servers through two-factor authentication over secure data connections.
• Hosting database servers in secured, ISO 27001-certified data centers.
• Backing up databases and storing them both internally and externally.
• Continuously monitoring systems and servers, with regular monthly updates.

Striking the Right Balance Between Awareness and Measures

Ensuring the security of corporate data hinges on combining awareness with “harder” measures, such as systems that integrate with your business processes or come with proper certifications.
