Data security is a broad term that covers a variety of tools, techniques and methods to safeguard digital information from unauthorized access, alterations and theft throughout its cycle. This includes physical security of hardware and storage devices, as well as logical security of software applications and organizational policies and procedures. Security strategies for data that are strong are vital to ensure trust in business and complying with the regulations and also to avoid costly data breaches.

Data security can be described in terms of:

Authentication is the process of precisely authenticating users prior to giving access to sensitive information or systems. Authentication is the process of verifying the identity of an individual by using methods like PINs, passwords and swipe cards.

Encryption is the process of converting data into a coded form which can only be decoded by using a code, which safeguards information from cybercriminals even if it is accessed during transport. This is often used for securing credit card numbers and other financial details of personal nature.

Backup and recovery: This process creates, and keeps backups of data to ensure it can be recovered in the event of system malfunction, disaster, or corruption. A solid backup and recovery plan minimizes the chance of losing valuable data.

Data resilience: The ability to continue operating without interruption in the event of an outage of power or natural disaster. This is accomplished through the use of processes such as data masking, encryption redaction, and centralized management tools.
