About Data Security
Data Security is a process of protecting files, databases, and accounts on a network by adopting a set of controls, applications, and techniques that identify the relative importance of different datasets, their sensitivity, regulatory compliance requirements and then applying appropriate protections to secure those resources.
Similar to other approaches like perimeter security, file security or user behavioral security, data security is not the be all, end all for a security practice. It’s one method of evaluating and reducing the risk that comes with storing any kind of data.
The core elements of data security are confidentiality, integrity, and availability. Also known as the CIA triad, this is a security model and guide for organizations to keep their sensitive data protected from unauthorized access and data exfiltration.
1. Confidentiality ensures that data is accessed only by authorized individuals;
2. Integrity ensures that information is reliable as well as accurate;
3. Availability ensures that data is both available and accessible to satisfy business needs.
Firstly, the purpose of personal data protection isn’t to just protect person’s data, but to protect the fundamental rights and freedoms of persons that are related to that data. Whilst protecting personal data it is possible to ensure that persons’ rights and freedoms aren’t being violated. For example, incorrect processing of personal data, might bring about a situation where a person is overlooked for a job opportunity or, even worse, loses current job.
Secondly, not complying with the personal data protection regulations can lead to even harsher situations, where it’s possible to extract all the money from a person’s bank account or even cause a life-threatening situation by manipulating health information.
Thirdly, data protection regulations are necessary for ensuring and fair and consumer friendly commerce and provision of services. Personal data protection regulations cause a situation, where, for example, personal data can’t be sold freely which means that people have a greater control over who makes them offers and what kind of offers they make.
