Codification in the new European Data Protection Regulation.

Riestra Abogados. 

Today, more than ever, companies need to robustly protect their information against potential attacks or intrusions into their IT systems, given the risks that a potential security breach would pose to both the company and its customers or potential clients. Hence, encryption and two-factor authentication (also known as 2FA) are considered the basic pillars of security.

However, the preconceived idea that systems are complex to manage and implement is now obsolete. To this end, we refer to the statement made by Arturo Ribagorda, Professor of Computer Science at UC3M, who states the following: "The idea that implementing data protection security measures is difficult is a misconception and fallacy."

Importance of encryption

Today, no company, no matter how small or large, can guarantee that it has not suffered or will not suffer an attack on its assets, meaning the computer files it holds.

Therefore, the AGPD, in its report No. 494/2009, highlights the importance of adequate data protection: "The security of the exchange of personal information, for which high-level security measures must be adopted, particularly data encryption requirements, is not a trivial matter, nor a mere administrative procedure, nor a matter of convenience. It is the technical means by which the protection of a fundamental right is guaranteed, and the time and resources necessary for its proper implementation must be dedicated to it."

What encryption options do we have?

The encryption options applicable in Spain are based on both the provisions of European regulations on this matter and Article 104 of the Regulation implementing the Organic Law on Data Protection (RDLOPD). Therefore, companies that are required to adopt encryption measures due to the volume of assets, etc., may choose between:

- Robust professional encryption system.

- Any other system that guarantees that the information will not be intelligible or tampered with by persons outside the company.

Article 104 of the LOPD Regulation:

“When, in accordance with Article 81.3, high-level security measures must be implemented, the transmission of personal data through public networks or wireless electronic communications networks shall be carried out by encrypting said data or using any other mechanism that guarantees that the information is not intelligible or tampered with by third parties.”

Therefore, companies must adhere to these encryption systems and omit those that do not guarantee adequate security, such as various tools for personal use or file compression. The AGPD has issued a statement on the matter, stating the following: "Products that generate PDF files, or the one generated by WinZip, have known vulnerabilities, and freely distributed tools are available that exploit these vulnerabilities. More specifically, not only are utilities that break the protections of PDF or ZIP files easily available on the Internet, but the very algorithm that encrypts PDF documents, the RC4 algorithm, is clearly vulnerable" (Report 494/2009).

New features introduced by the new Data Protection Regulation

Due to the entry into force of the new General Data Protection Regulation (EU), there are three "levels" of encryption:

Mandatory encryption:

- This is mandated by the state; that is, in Spain, all companies or organizations that process particularly sensitive data (ethnic or racial origin, political opinions, religious beliefs, etc.) and therefore must apply high-level security measures will be required to adopt encryption systems to protect their files.

- All companies that have adhered to a code of conduct must adopt an encryption system, provided that such code so requires.

- Companies that process biometric data or systematically monitor publicly accessible areas must encrypt the data they collect.

- If there is a definite risk, the company or organization in question must adopt an encryption system to mitigate it, regardless of the importance of the data handled.

Recommended Encryption:

- All companies, regardless of the volume or importance of the personal data they process, should implement an encryption system to safeguard their computer files and provide greater security for their users.

Voluntary Encryption:

- The encryption system will be an optional measure for companies that process disassociated data, since it would not be possible to identify a natural person through it.

Obligations for the controller and the processor

Pursuant to Article 32 of the GDPR (EU), both the controller and the processor must implement appropriate technical and organizational measures, such as:

- Pseudonymization and encryption of personal data;

- The ability to guarantee the ongoing confidentiality, integrity, availability, and resilience of processing systems and services;

- The ability to restore the availability of and access to personal data quickly in the event of a physical or technical incident;

- A process for regularly verifying, evaluating, and assessing the effectiveness of technical and organizational measures to ensure the security of processing.

What obligations exist in the event of a security breach?

According to the GDPR (EU), ALL companies are required to notify any security breach, no matter how small, and communicate it to the data subjects. Therefore, immediately upon the company becoming aware of such a vulnerability in its security system, it must notify the General Data Protection Agency (GDPR) or the competent supervisory authority.

This notification must be made as quickly as possible and, whenever possible, within 72 hours of becoming aware of the security breach.

As can be seen from the above, the encryption system is a somewhat mandatory security measure in certain cases and is always recommended by the European institutions. The General Data Protection Agency (GDPR) has adopted it as its own, given that millions of attacks are carried out daily against any type of company or organization to access personal data. Therefore, the ultimate objective of encryption is to protect the rights and freedoms of individuals.

Therefore, sanctions could range from administrative fines of up to €10 million or an amount equivalent to 2% of the total annual global turnover of the previous financial year, whichever is higher (Article 83 GDPR (EU).
