Data security is the process of protecting the digital information from theft and access by unauthorized people whether in the state of rest during transport, or when it’s being employed. It involves a variety of tools, technologies, and practices such as access control, encryption, and data masking. Physical security is also a part of it to safeguard equipment and facilities which store sensitive data.

Prevention of breaches: In addition to the need to ensure compliance with regulations, preventing data leaks can help maintain trust with customers and helps create an image of trust for the company. This is even true for small companies, which could be harmed by reputational damage and financial losses when customers‘ PII is exposed.

Secures important information: Sensitive information, like the bank’s client list or hospital’s patient files isn’t a good idea to be viewed by prying eyes. Keeping this type of information secure helps companies retain a competitive edge.

Provides accessibility: Data that isn’t accessible when it is needed is of no value to anyone, which is why it’s important to have a backup plan for recovering data that’s saved. There are options to aid in preventing downtime caused by ransomware attacks. These include cloud-based disaster recover as a service, and data snapshots.

Eliminates obsolete information: If an organization no longer requires certain kinds of data, it should remove them entirely from its systems instead of simply rewriting the space with new data. This is known as data erasure and involves using software to erase the files on any kind of device so that they cannot be recovered.
