What are the benefits of data encryption in Information Security?

Encryption is the procedure of changing plain text into ciphertext, i.e., changing the text from readable format to non-readable format to protect the conversation among two parties or from the unauthorized person.

A private key can be used to fastly encrypt the plain text. There are several techniques and algorithms have been produced to encrypt the encryption. For instance, substitution techniques, transposition techniques, MD5 algorithm, SHA algorithm, IDEA algorithm, etc.

Data encryption is an approach of securing information confidentiality by converting it to encoded information, known as ciphertext. It can only be decoded with a unique decryption key, produced either at the time of encryption or sooner.

Data encryption can be used during information storage or transmission and is generally used in conjunction with authentication services to provide that keys are only supported to or used by authorized users.

Data encryption solutions are solutions that allows an organization to perform encryption at large scale. They contains advanced encryption algorithms, together with administration tools that provide deploy encryption, handle keys and passwords, set access policies, and monitor how encryption is implemented across the organization.

There are various benefits of data encryption are as follows −

Supports compliance − Encryption is explicitly needed by some regulations and market standards. It is having strong encryption in place can provide demonstrate to auditors that sensitive information is well secured by the organization.

Encryption Provides Privacy − Data Encryption is not only beneficial for organization or the military, but normal computer users can also use it to save sensitive data including Bank Account details, medical records, etc., safe. Without proper Encryption, anyone who can access the device will be capable to view and copy it.

Providing Security at All Times − There are several tools to password protect a folder or some local storage information that someone it can choose, but it is the only true way to secure information in its entirety. This is possible because without proper decryption of information, no one can use it.

Protects data in cloud storage − When data is saved in the public cloud, it can be exposed to a much broader range of threats, such as accidental exposure to the Internet, access by some cloud tenants, and by malicious insiders at the cloud provider. Encrypting information in cloud storage by default supported a layer of security against all these threats.

Protects intellectual property − Intellectual property is a strategic asset that can be value millions. By encrypting this information and securely handling encryption keys, an organization can render it counterproductive to an attacker.

Key management − This is an essential element of encryption management. The solution should create it convenient to make encryption keys, deliver them to information owners, back them up, and damage them when access is revoked.
