Data security is an umbrella term that includes a range of tools, technologies and practices to protect digital information from unauthorized access, alterations and theft throughout its cycle. This includes the physical security of hardware and storage devices as well as the logical security software applications, and organizational policies and procedures. Security strategies for data that are strong are vital for maintaining business trust and adhering to regulations and also making sure that there are no costly data breaches.
Security of data can be classified into:
Authentication is the process of precisely identifying a user before granting access to sensitive data or systems. Authentication involves the verification of an individual’s identity by using methods like passwords, PINs, security tokens, swipe cards and biometrics.
Encryption is a process that transforms data into a coded format that can only deciphered by a key. It safeguards information from cybercriminals, even if it is intercepted in transit. This is commonly used to safeguard credit card numbers as well as personal financial information.
Backup and recovery: The process of making and keeping backups of data to ensure that they will be retrieved in case of a system malfunction or a disaster. It also prevents corruption of data. A continuous backup and recovery strategy minimizes the chance of losing important data.
Data resilience: The ability to continue operations without interruption in the case of a power failure or natural catastrophe. This is achieved through using a combination of data masking redaction, encryption and encryption tools, as well as central management software.
