Data security protects organizational data and systems from unauthorized access, use and modification. This helps prevent data breaches that can cause disruption to business operations and financial losses, compliance penalties, and reputational damage. Modern approaches to protecting data include a combination of tools, methods and best practices that are based on three pillars: Confidentiality, Integrity and Integrity.

The first step towards effective data security is to create and maintaining an inventory and mapping of your data sets. Data cataloguing in your data centers and network-attached devices, desktops, mobiles, cloud services and software applications is vital. It is crucial to think about physical storage devices like USB sticks and external hard drives, and even discarded documents and printed documents. These are often overlooked and can contain a wealth of confidential information, which makes them a prime target for cybercriminals.

Once you have visibility into your data sets the next step is to classify your sensitive data so that you can better understand what it is and where it is within your system. This lets you prioritize your security efforts, ensuring that the highest-value data is secured while less important information remains easily accessible. This lets you adhere with regulatory and industry standards, such as those applicable to the health care, finance and telecommunications industry.
