Using said key and a suitable encryption algorithm, the plaintext is converted into the encrypted piece of data, also known as ciphertext. There are multiple encryption algorithms, each of which differs by application and security index.Īpart from the algorithms, one also needs an encryption key. The plaintext needs to be passed via some encryption algorithms, which are basically mathematical calculations to be done on raw information. The data that needs to be encrypted is termed plaintext or cleartext. It’s the most straightforward and crucial means of protecting information that passes from endpoints to servers.Ĭonsidering the elevated risk of cybercrime today, every person and group that uses the internet should be familiar with and incorporate basic encryption techniques, at the very least. They go on to say that encryption is considered the basic building block of data security, widely used by large organizations, small businesses, and individual consumers. Noted antivirus and endpoint security experts at Kaspersky define encryption as “… the conversion of data from a readable format into an encoded format that can only be read or processed after it's been decrypted.” Almost everything we see on the internet has passed through some layer of encryption, be it websites or applications. In order to preserve the integrity of our data, encryption is a vital tool whose value cannot be overstated. Encryption can be applied to documents, files, messages, or any other form of communication over a network. This is done to prevent prying eyes from reading confidential data in transit. Enroll now! What is Data Encryption in Network Security?ĭata encryption is the process of converting data from a readable format to a scrambled piece of information. Learn the types of attacks on a system, the techniques used, and more with the Certified Ethical Hacking Course.
The real challenge is deciding which techniques an internet security expert should employ that best suits their organization’s specific situation. In a world where cybercrimes are on the rise, it’s comforting to know that there are as many methods available to protect network security as there are ways of trying to penetrate it. However, there are a handful of different encryption methods available, so how do you choose? Data encryption is a common and effective security method-a sound choice for protecting an organization’s information.
