What is the role of encryption in cyber security?

Encryption plays a crucial role in protecting sensitive data from unauthorized access or tampering by converting the data into a coded format that only authorized parties can access, usually through the use of encryption keys. This process ensures that even if unauthorized individuals gain access to the data, they cannot read or understand it without the decryption key. Encryption helps safeguard information during transmission over networks and while stored on devices or servers, making it significantly harder for cybercriminals to intercept, view, or manipulate the data. Proper implementation of encryption techniques is essential for ensuring data confidentiality and integrity.
