Data security helps protect data and systems from the risk of unauthorized access, use, and alteration. This helps avoid data breaches that can cause disruption to businesses financial loss as well as compliance penalties and reputational damage. Modern approaches to protecting data comprise a mix of tools, techniques and best practices that are based on three pillars: Confidentiality and Integrity.
The first step towards 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-connected devices including desktops, mobiles, cloud services and software applications is vital. It is also essential to take into account physical storage, such as external hard drives, USB sticks, and even the discarded printed documents and files. They are often ignored, but can contain valuable confidential data. Cybercriminals will take advantage of this.
Once you’ve gotten a better understanding of your data security data sets the next step is to categorize your sensitive information so that you can better understand how and where it exists within your system. This allows you to prioritize your security efforts by ensuring that the most valuable information is protected while less important information remains readily accessible. This allows you to comply with the regulations and requirements of your industry, such as those that pertain to the health care, finance, and telecommunications industries.
