Data protection and security are essential for the continuity of business. Data protection is not nice to have, but it is required by the legal system. Sensitive data, such as user information, email addresses, geographical addresses, and payment information, should be protected against any data breach. There are several other topics related to data security, such as data privacy, retention, and loss prevention.
There are several levels of data protection, often defined in the data protection policy and by the country's legal system. Data protection policy often defines data dissemination to other parties, users authorized to access the data, and so on. Data should be protected on different levels, including transferring and encrypting data on storage devices. Data security is a huge topic and often there are data security managers dedicated only to these tasks.
