The Three Pillars of Data Security

Data security guards the data of organizations and systems from the risk of unauthorized access, use, and alteration. This can help prevent data breaches that can result in business disruption financial loss, compliance penalties and reputational damage. Modern approaches to data protection include a combination tools, technologies and best practice that are based on three pillars: Confidentiality and Integrity.

The first step to effective data security is to create and maintaining an inventory and mapping of your data sets. This includes cataloguing all data stored in your data centers, network-attached storage, mobile devices, desktops, cloud services offered by third-party companies and software applications. It’s also important to take into account physical storage devices like external hard drives and USB sticks, and even discarded printed files and documentation. These are often overlooked but could contain a wealth of confidential information. Cybercriminals will make use of this.

Once you have visibility of your data sets, you’ll have to classify sensitive information in order to understand where and how it is situated within your system. This lets you prioritize your security efforts by ensuring that the most valuable information is protected, while less critical information is accessible. It also allows you to meet regulatory and industry requirements similar to those that apply to finance, health care and telecoms.
