Why is data security important? Show
Data security is the practice of protecting digital information from unauthorized access, corruption, or theft throughout its entire lifecycle. It’s a concept that encompasses every aspect of information security from the physical security of hardware and storage devices to administrative and access controls, as well as the logical security of software applications. It also includes organizational policies and procedures. When properly implemented, robust data security strategies will protect an organization’s information assets against cybercriminal activities, but they also guard against insider threats and human error, which remains among the leading causes of data breaches today. Data security involves deploying tools and technologies that enhance the organization’s visibility into where its critical data resides and how it is used. Ideally, these tools should be able to apply protections like encryption, data masking, and redaction of sensitive files, and should automate reporting to streamline audits and adhering to regulatory requirements. Business challenges The business value of data has never been greater than it is today. The loss of trade secrets or intellectual property (IP) can impact future innovations and profitability. So, trustworthiness is increasingly important to consumers, with a full 75% reporting that they will not purchase from companies they don’t trust to protect their data. More on data security
Encryption Data Erasure Data Masking Data Resiliency Resiliency is determined by how well an organization endures or recovers from any type of failure – from hardware problems to power shortages and other events that affect data availability (PDF, 256 KB). Speed of recovery is critical to minimize impact. Data security capabilities and solutions Data security tools and technologies should address the growing challenges inherent in securing today’s complex, distributed, hybrid, and/or multicloud computing environments. These include understanding where data resides, keeping track of who has access to it, and blocking high-risk activities and potentially dangerous file movements. Comprehensive data protection solutions that enable enterprises to adopt a centralized approach to monitoring and policy enforcement can simplify the task. Data discovery and classification tools Data and file activity monitoring Vulnerability assessment and risk analysis tools Automated compliance reporting
A comprehensive data security strategy incorporates people, processes, and technologies. Establishing appropriate controls and policies is as much a question of organizational culture as it is of deploying the right tool set. This means making information security a priority across all areas of the enterprise. Physical
