Data security is an umbrella term that encompasses a range of tools, technologies, and practices to safeguard digital information from unauthorized access, theft, and corruption throughout its lifecycle. This includes the physical security of storage devices and hardware, the logical security software applications, and the policies of the organization and procedures. Data security strategies that are robust are essential to ensure trust in business and complying with the regulations and also protecting against costly data breaches.
Security of data can be classified into:
Authentication: The process of accurately authenticating users prior to giving access to sensitive information or systems. Authentication is the process of confirming an individual’s identity by using methods like PINs, passwords and swipe cards.
Encryption – This procedure transforms information into a codified format that can only deciphered by a key. It shields information from cybercriminals, even when it is intercepted in transit. This is commonly used to protect credit card numbers and personal financial information.
Backup and recovery This process creates and keeps backups of data to ensure it can be retrieved in the event of system failure, disaster or data corruption. A solid backup and recovery plan reduces the risk of losing valuable data.
Data resiliency: The ability to continue operations with no interruption in the event of a power outage or natural disaster. This is accomplished by using a combination of data masking redaction, encryption, and encryption tools, in addition to centralized management software.
