Data security is the protection of data and systems against unauthorized access, modification and use. This helps to avoid data breaches, which could lead to business disruption, financial losses, compliance penalties, and reputational damage. Modern approaches to data protection comprise a mix of tools, technology and best practices that are based on three pillars: Confidentiality and Integrity.
The first step in effective data security is to create and maintaining an inventory and mapping of your data sets. The cataloguing of data from your data centers and network-attached devices like desktops, mobiles cloud services, and software applications is vital. It is crucial to think about physical storage options like USB sticks and external hard drives, as well as discarded documents and printed documents. These are often ignored and can hold a lot of confidential information, making them a popular target for cybercriminals.
Once you’ve gotten a better understanding of your data sets you’ll have to classify sensitive information in order to know the location and where it is located within your infrastructure. This will enable you to prioritize security measures, making sure that only the most crucial information is protected, and that less-critical information remains easily accessible. This allows you to comply with the regulations and requirements of your industry, such as those pertaining to the health care, finance and telecommunications industry.
