Data security helps protect data and systems from unauthorized access, use and alteration. This helps prevent data breaches that could result in business disruption financial loss or penalties for compliance, as well as reputational damage. Modern approaches to data protection comprise a mix of tools, techniques and best practices that focus on three pillars: Confidentiality, Integrity and Integrity.
Data security starts with an extensive inventory and mapping. This involves cataloguing all data stored in your data centers, network-attached storage as well as desktops, mobile devices as well as third-party cloud services and software applications. It is essential to consider physical storage like USB sticks and external hard drives and also discarded documents and printed documents. They are often ignored but they could contain a wealth of confidential data. Cybercriminals will take advantage of this.
Once you’ve gotten a better understanding of your data sets the next step is to classify your sensitive information so you know how and where it exists within your infrastructure. This will help you prioritize security efforts, ensuring that only the most crucial data is protected and less-critical information remains easily accessible. It also lets you meet regulatory and industry requirements similar to those that apply to health care, finance and telecommunications.
