Answer: Encryption is basically important for securing data transmission over Networks, because it makes shows that sensitive information remains private and inaccessible to unauthorized users.
Below are the reasons specifying why encryption important in securing data transmission over networks:
Confidentiality
Encryption process encodes the data into the format which can be read only by the person having the correct decrypted key. So this mainly prevents the unauthorized users from getting the transmitted information and maintains confidentiality.
Integrity
Encryption over the network also verifies the roper data integrity by detecting any unauthorized changes during the data transmission.
Authentication
The encrypted data can be accomplished by digital signature or the certificates, which provides the extra layer of security known as authentication. These mainly verifies that the sender’s identity and ensures that the data has not been at least in a transmission route or the path.
Risk Mitigation
The encryption also reduced the risk of data breaches as even if we accepted as the interested data is unreadable without the proper credit decryption key. This indirectly mitigates the risk of theft.
Compliance
Various industries and regulations like GDPR or HIPAA, makes compulsory of the use of encryption to protect the sensitive data. Compliance with the standards is important for legal and ethical reasons.
