Data security is the protection of data and systems against unauthorised access, modification and use. This helps to prevent data breaches that can cause disruption to businesses financial losses, compliance penalties, and reputational damage. Modern approaches to data protection comprise a mix of tools, technologies and best practice that focus on three pillars: Confidentiality and Integrity.
The first step to ensuring data security is creating and maintaining an inventory and mapping of your data sets. This involves cataloguing all data stored in your data centers, network-attached storage as well as mobile devices, desktops as well as third-party cloud services and software applications. It’s important to consider physical storage like USB sticks and external hard drives, as well as old documents and printed documents. These are often ignored and can contain a wealth of confidential information, making them an attractive target for cybercriminals.
Once you have visibility into your data sets The next step is to classify your sensitive information so you can better understand how and where it exists within your system. This will allow you to prioritize security efforts, ensuring that only the most important data is protected and information that is not as critical is readily accessible. This enables you to conform to industry and regulatory requirements, such as those pertaining to the finance, health care and telecommunications industry.
