Data security is a broad term that includes many tools practices, technologies, and techniques to safeguard digital data from theft, unauthorized access, and loss throughout its lifetime. This includes physical security of hardware and storage devices, logical security of software applications and organizational policies and procedures. Security strategies for data are vital to ensure business trust, ensuring compliance with regulations and keeping data breaches from becoming costly.
Types of data security include:
Authentication: The process of accurately authenticating users prior to giving them access to sensitive information or systems. Authentication is the process of confirming the identity of an individual by using methods like PINs, passwords and swipe cards.
Encryption: This procedure converts information into a coded form that can only be deciphered by a key, thereby protecting information from cybercriminals even if it is intercepted during transit. This is usually used to safeguard personal information like credit card numbers and financial data.
Backup and recovery The process creates and creates backups of data to ensure that it is retrieved in the event of system failure, natural disaster or data corruption. A consistent backup strategy can reduce the chance of losing important data.
Data resilience: The ability to operate without interruption in the event of a loss of power or natural catastrophe. This is achieved through a combination of procedures like data masking, encryption redaction and centralized management tools.
