The Three Pillars of Data Security
Data security is the safeguarding of the systems and data belonging to an organization against unauthorized access, modification and use. This can help prevent data breaches that can cause disruption to businesses and financial loss and compliance penalties as well as reputational damage. Modern approaches to data security consist of a combination of tools methods and best practices that are based on three pillars: Confidentiality, Integrity and Integrity.
Data security begins with a thorough inventory and mapping. The cataloguing of data from your data centers, network-connected devices like desktops, mobiles cloud services and software applications is important. It is also essential to consider physical storage devices like external hard drives and USB sticks, and even removed printed documents and printed files. These are often overlooked and can hold a lot of sensitive information, making them a prime target for cybercriminals.
Once you’ve got a clear view of your data sets you’ll need to identify sensitive data to determine what it is and where it’s situated within your system. This will enable you to prioritize security measures, making sure that only the most important data is protected and less critical information is easily accessible. It also allows you to comply with industry and regulatory standards, like those applicable to health care, finance and communications.
