and data security

Due to the technological progress, with which both private individuals and companies have access to various types of data, appropriate security measures are an absolute must. In this category, we will inform you about the terms data protection and data security. In addition, you will learn which measures go hand in hand with this.

Why are data security and data protection essential?

It is not uncommon for private individuals and companies to be victims of cyber attacks, credit card fraud or data misuse. The consequences include, for example, subscriptions that those affected never took out, telephone harassment through dubious surveys or fraudulent schemes. The stakes are often high. Data security is therefore highly relevant in both the private and professional spheres.

What do the terms mean? Data protection and data security?

What data protection and data security have in common is the common goal of keeping data confidential and reliably protecting it. Nevertheless, the terms differ in some respects:

The term data security refers to the general protection of data and specifies appropriate measures to prevent data loss or data corruption. No distinction is made between personal and other data.

The guiding question is: How do I protect data from unauthorized access? The focus is therefore not on whether and what data may be collected, but on what security measures are necessary.

Data protection, on the other hand, refers to the protection of personal data and the legal situation. The question here is: Who is allowed to collect, process or use which data?

What are the goals the GDPR?

Among the principles that should ensure data protection and data security according to the GDPR, and thus the objectives they should pursue:

  • Lawfulness: This principle is self-explanatory - there should be no unlawful data processing.
  • Purpose limitation: Personal data may only be collected and processed by third parties if there are legitimate purposes. Controllers shall determine those purposes prior to processing.
  • Data minimization: In data processing, the guiding principle is: "As much as necessary, as little as possible." Unnecessary data collection is to be refrained from.
  • Accuracy: No outdated or incorrect data shall be processed. Otherwise, correction or deletion is inevitable.
  • Memory limitation: Data is only stored as long as it serves the purpose. If not, deletion or anonymization of the data is pending.
  • Availability: There must be a failover at all times that allows continuous access to the data.
  • Integrity and confidentiality: Integrity in this context means that the data is credible and unaltered - i.e., not manipulated. With the help of appropriate organizational and technical measures, companies can protect personal data from unlawful access and unauthorized processing, as well as from destruction or damage.

Measures for data security and data protection

Data protection or data security measures succeed, among other things, through end-to-end encryption, authentication, and adherence to certain guidelines.

measures for more security for cloud storage

In the case of cloud storage, both private individuals and companies should pay attention to triple encryption and the so-called zero knowledge principle. This means that even the cloud provider itself has no insight into stored data.

In addition, users can gain transparent insight into the source code via open source software and thus see, among other things, who has access to which data. Backups with snapshots are equally important. In the case of criminal third-party encryption and access denial, so-called ransomwares, they restore your data to its original state.

Measures for more security for communication

The same security measures apply to everyday communications. E-mail addresses or contact information should generally only be passed on to other people after consultation and for a valid reason. In addition, two-factor authentication offers a high level of protection. When you log in, you confirm your identity in addition to your password, for example, by means of a PIN code that you receive by text message.

Furthermore, content can be encrypted using additional passwords. Some companies and institutions also use internal messaging tools to prevent third-party interference or espionage.
