Data security helps protect data and systems from unauthorised access, use and alteration. This can help prevent data breaches that can result in business disruption and financial loss and compliance penalties as well as reputation damage. Modern methods of protecting data consist of a combination of tools techniques and best practices that focus on three pillars: Confidentiality and Integrity.
Data security starts with an extensive inventory and mapping. This includes cataloging all the data stored in your data centers, storage devices that are network-attached and mobile devices, desktops as well as third-party cloud services and software applications. It is essential to consider physical storage devices like USB sticks and external hard drives as well as discarded documents and printed documents. These are often ignored and could contain a vast amount of confidential data, making them a popular target for cybercriminals.
Once you are aware of your data sets you’ll need to categorize sensitive data to know the location and where it is situated within your infrastructure. This lets you prioritize your security efforts by making sure that the most valuable information is protected while less important information remains easily accessible. This also allows you to comply with industry and regulatory requirements similar to those that apply to finance, health care and telecommunications.
