Data security is the protection of organizational data and systems against unauthorized access, modification and use. This can help prevent data breaches that could cause disruption to business operations financial loss and compliance penalties as well as reputation damage. Modern approaches to protecting data comprise a mix of tools, methods and best practices that are based on three pillars: Confidentiality, Integrity and Integrity.
The first step to effective data security is to create and maintaining an inventory and mapping of your data sets. This includes cataloging all the data stored in your data centers, network-attached storage as well as mobile devices, desktops and cloud services from third-party providers as well as software applications. It’s also important to take into account physical storage devices like external hard drives, USB sticks, and even discarded printed files and documentation. They are often ignored but could contain a wealth of confidential information. Cybercriminals will make use of this.
Once you’ve got a clear view of your data sets, the next step is to classify your sensitive data so that you are aware of the location and how it is stored within your infrastructure. This will allow you to prioritize security measures, ensuring that only the most vital data is protected and less important information is accessible. This enables you to conform with regulatory and industry standards, such as those applicable to the health care, finance, and telecommunications industries.
