What is encryption, and how is it used to protect network data?
Aryan Kumar
26-Nov-2023Encryption is a process of converting information into a coded or unreadable format to secure it from unauthorized access. It involves the use of mathematical algorithms and cryptographic keys to transform plaintext (original data) into ciphertext (encrypted data). The primary purpose of encryption is to protect sensitive information and ensure confidentiality, integrity, and sometimes authenticity in communication and storage.
Here's how encryption is used to protect network data:
Confidentiality:
Authentication:
Integrity:
Secure Communication:
Key Exchange:
Secure Email Communication:
Wireless Security:
File and Disk Encryption:
Virtual Private Networks (VPNs):
In summary, encryption is a fundamental tool in network security, ensuring that data remains confidential, integral, and authenticated throughout its lifecycle, whether in transit over the network or at rest on devices or servers. It is a crucial component in protecting sensitive information in an increasingly interconnected digital world.
