If personal data falls into the wrong hands, it can lead to a variety of problems, including identity theft, reputational damage, fraud, property-related crimes, and other harmful consequences. Data breaches and new data leaks are reported regularly. It is therefore wise to learn in advance how to protect your personal data and reduce the risk of harm before an incident occurs.

Many different registers and databases contain information, some of which constitutes personal data. If information is stored in an information system, it may also become the target of a data breach. It is the responsibility of the data controller to protect and secure that information. If data is stolen or falls into the wrong hands, it can cause significant harm to the individuals concerned. The more sensitive the information, the greater the potential harm if it is disclosed, and the more important it is to store it securely.

Address details, names, patient records, contact information, educational records, asset information, permit details, passport numbers, personal identity codes, hobbies, contacts, customer relationships, ownership interests, and even shoe size can all constitute personal data. However, not all of this information requires the same level of protection or needs to be stored under the same security measures. When combined, however, these data can form a significant collection of personal information that, if misused, may cause considerable harm.
