Data security is an umbrella term that covers a variety of tools techniques, practices, and technologies to safeguard digital data from theft, unauthorized access, and loss throughout its life. This includes the physical security of storage devices and hardware, the logical security software applications, as well as the organizational policies and procedures. Data security strategies that are robust are essential for maintaining business trust and ensuring compliance with regulations as well as to avoid costly data breaches.
Data security can be classified into:
Authentication means the process of accurately authenticating users prior to giving them access to sensitive information or systems. Authentication is the process of verifying the identity of an individual using methods such a PIN, passwords, and swipe cards.
Encryption: This process converts data into a coded format that can only be deciphered by using a code, which safeguards information from cybercriminals even if it gets snatched during transit. This is typically used to secure credit card numbers and other financial data of a person’s personal.
Backup and recovery is the process of creating and storing copies of data to ensure that they can be retrieved if there is an outage or disaster, or if there is a corruption of data. A solid backup and recovery plan minimizes the chance of losing important data.
Resiliency of data: The capacity to continue operations with no interruption in the event of a power outage or natural catastrophe. This is achieved through a combination of procedures like data masking, encryption redaction and centralized management tools.
