I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

Encryption is a process of converting data into an unreadable format. This makes it impossible for unauthorized users to access the data, even if they have physical access to the storage device or network where the data is stored.

Encryption is an important security measure for protecting data at rest and data in transit.

  • Data at rest is data that is stored on a physical device, such as a hard drive or a USB drive. Encryption can be used to protect data at rest by converting the data into an unreadable format before it is stored. This makes it impossible for unauthorized users to access the data, even if they have physical access to the storage device.
  • Data in transit is data that is being transmitted over a network, such as the internet. Encryption can be used to protect data in transit by converting the data into an unreadable format before it is transmitted. This makes it impossible for unauthorized users to intercept the data and read it, even if they have access to the network.

There are two main types of encryption: symmetric encryption and asymmetric encryption.

  • Symmetric encryption uses the same key to encrypt and decrypt data. This type of encryption is faster than asymmetric encryption, but it is not as secure.
  • Asymmetric encryption uses two keys: a public key and a private key. The public key can be used to encrypt data, but it cannot be used to decrypt data. The private key can be used to decrypt data, but it cannot be used to encrypt data. This type of encryption is more secure than symmetric encryption, but it is also slower.

The best type of encryption to use will depend on the specific application. In general, symmetric encryption is a good choice for applications that require speed, while asymmetric encryption is a good choice for applications that require security.

Here are some of the benefits of using encryption to secure data at rest and data in transit:

  • Prevents unauthorized access to data: Encryption makes it impossible for unauthorized users to access data, even if they have physical access to the storage device or network where the data is stored.
  • Protects data from being intercepted: Encryption makes it impossible for unauthorized users to intercept data in transit and read it.
  • Complies with security regulations: Many security regulations, such as the Payment Card Industry Data Security Standard (PCI DSS) and the Health Insurance Portability and Accountability Act (HIPAA), require organizations to encrypt data.

By using encryption, organizations can help to protect their data from unauthorized access and keep their data secure.
