In the world of IT where cases of cybercrimes are on a surge, it’s relieving to know that various methods can help to protect to network security of an organization. It is important to decide on the technique that can best suit the organization’s specific situation.
Encryption is a process of transforming plaintext (unencrypted data) to ciphertext (encrypted data) so that only people having a secret key (formally known as the decryption key) can have access to that encrypted data and will be able to decode the information.
Data encryption is a popular security method used by organizations for protecting an organization’s data. However, there are several different encryption techniques available, so how do you decide which one to choose?
Here we are going to discuss the three most effective data encryption techniques available to protect an organization’s security network. Before we proceed with effective data encryption techniques, let’s have a brief overview of the basics of data encryption, how it works and the need for data encryption.
In this article let us look at:
Encryption is all about transforming intelligible numbers or text sounds or images into jumbled messages that are not easy to decipher.
Encryption is the process of transforming data from a readable format into an encrypted format that can only be read by authorized users who can convert the encoded data back to original data and access the original data. The process of converting an original message into an encoded format by the sender is known as encryption and the process of converting the encoded message back to its original format is known as decryption
As the risk of cybersecurity threats is increasing day by day, it is important to know at least the basic encryption technique by the users using the internet to safeguard their security at the very least.
Whenever you send a secure text message using your smartphone. Here’s how end-to-end encryption works to keep your data private while on transit. Smartphone has two keys 9public key and private key) that encrypt and decrypt the texts. The public key is a shared key and is used as a part of the encryption protocol while a private key is only on the device and is never shared with other people. A combination of public and private keys is used to create a temporary shared key while sending a secure text. Let’s look at how this works-
Mr. A sends a message to Mr. B which at the same time causes an exchange of public keys. Both Mr. A and Mr. B use the other person’s public key along with their private key to create a temporary shared key. They then use the shared key to encode their messages and their public keys are used to verify that those shared keys are authentic.
The shared keys are being deleted and regenerated continuously which makes sure that Mr. B’s chat cannot be decrypted in the future. An intruder could see that Mr. A and Mr. B exchanged messages but because the intruder doesn’t have the shared key of Mr. A and Mr. B, these texts cannot be decoded by the intruder.
In this era of technology, encryption is a necessity. It is one of the most powerful ways to keep our data safe. Here are some reasons as to why there is a need for data encryption-
Let’s discuss some common and important encryption techniques.
The data encryption techniques can be divided into three types. These are as follows-
Here are some common encryption algorithms –
As cyber threats are growing in their number and their complexity, there is a huge demand for cybersecurity professionals. The job in this field offers you a lot of diverse, interesting, and challenging roles to keep you growing and learning. If you want to pursue a career in network security you can go for various certification courses offered by various institutions. To gain advanced knowledge and skills, one can go for CISM, CISA, CompTIA, and COBIT 2019 enterprise-level security training courses.
We hope this article would be useful for explaining to you encryption techniques for protecting the network security of your organization.
