Protect Your Data Using Encryption - Cyber Security? ›

Encryption of Confidential data communicated between a user's browser and a web-based application should be provided through the use of secure protocols (e.g., HTTPS, TLS/SSL, etc.) The display of confidential data should be limited to only what is required by the user's authorized use of the application.

A key is used to encrypt and decrypt data, and encryption at rest keeps the key safe. You can use a PIN, password or hardware authentication system to protect the key, making it impossible for hackers to steal data even if they have physical access to the device.

Data Encryption Definition

Data encryption converts data from a readable, plaintext format into an unreadable, encoded format: ciphertext. Users and processes can only read and process encrypted data after it is decrypted. The decryption key is secret, so it must be protected against unauthorized access.

It helps protect private information, sensitive data, and can enhance the security of communication between client apps and servers. In essence, when your data is encrypted, even if an unauthorized person or entity gains access to it, they will not be able to read it.

Data encryption is a security method that translates data into a code, or ciphertext, that can only be read by people with access to a secret key or password. The unencrypted data is called plaintext. The science of encrypting and decrypting information is known as cryptography.

An encryption key is a string of specifically organized bits designed to unscramble and decipher encrypted data. Each key is specific to a specific encryption code, therefore making each key unique and difficult to replicable.

There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.

Advanced Encryption Standard (AES)

AES has three different key lengths to encrypt and decrypt a block of messages: 128-bit, 192-bit, and 256-bit. AES is widely used for protecting data at rest in such applications as databases and hard drives.

After ransomware has gained access to a system, it can begin encrypting its files. Since encryption functionality is built into an operating system, this simply involves accessing files, encrypting them with an attacker-controlled key, and replacing the originals with the encrypted versions.

How encrypting data prevents unauthorized access? ›

Encryption is the process of concealing data by using a code. After encryption, in order to read or use the concealed data, the code used during encryption must be known. This process is called decryption. Encryption and decryption are used to allow access to data only to those who have the code.

Security threats – attacks such as denial of service, malware, database invasion and unauthorised internet access are highly prevalent, but can all be averted using cyber security encryption. Data interception – as data is passed over communication channels such as email, it can be intercepted and stolen.

Multi-factor authentication.

Multi-factor authentication is a process that asks the user to verify their identity in multiple ways — 2FA typically asks you to enter your login credentials, along with a code sent through email or text messages. The additional confirmation creates an extra hurdle for password thieves.

Encryption uses cryptography to conceal information by altering it so that it appears to be random, unintelligible data. With encryption, you need a password to view data stored on hard drives, computers, smartphones and in the cloud, as well as in transit data on the internet.

There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.

A strong encryption algorithm requires a strong encryption key, a strong mathematical algorithm, and a complex encryption process. Strong encryption keys are passwords for encryption. The longer the password or the more complex the password, the more difficult it will be to guess.

File encryption is a security method that converts your files into ciphertext or unreadable data. By using this method, you may be sure that even if unauthorized people access your files, they won't be able to understand the contents without the decryption key.

Encryption can be an effective information protection control when it is necessary to possess confidential data. Encryption is the process of concealing data by using a code. After encryption, in order to read or use the concealed data, the code used during encryption must be known. This process is called decryption.
