To prevent unauthorised access and possible changes to your data, data security measures are in order. Such measures, on the one hand, serve to protect personal data and confidential information and on the other hand offer protection against unauthorised manipulation or erasure of files (intentional or unintentional).
Data security can be considerably increased with the help of technical measures. However, these must be accompanied by organisational measures in the form of policies and guidelines.
in the video below several measures which directly contribute to data security are detailed: limit access with passwords, encrypt data and securely dispose of data that you no longer need. These measures are exemplified and supplemented with other measures in the tabs below the video (LSI Storage, 2009).
