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 helps in preventing data breaches that can cause disruption to businesses and financial losses as well as compliance penalties and reputational damage. Modern approaches to data security comprise a mix of technologies, tools and best practices that concentrate on the three main pillars of security for data which are: Confidentiality (preventing information from being read or read without authorization) and Integrity (ensuring that the information is accurate and is not altered) and Availability (ensuring that information is readily available whenever it is needed).

Data security starts with an exhaustive inventory and mapping. This involves cataloguing all data stored in your data centers, network-attached storage, mobile devices, desktops as well as third-party cloud services and software applications. It’s also important to consider physical storage options, such as external hard drives, USB sticks, and even removed printed documents and printed files. They are often ignored however they can contain a wealth of confidential data. Cybercriminals will take advantage of this.

Once you have visibility of your data sets, you will need to classify sensitive information to know the location and where it is in your infrastructure. This lets you prioritize your security efforts, ensuring that the most valuable information is secured while less critical information remains readily accessible. It also allows you to comply with industry and regulatory standards, like those applicable to finance, health care and telecommunications.
