1. How Encryption For Strong Security
Works
1.Networks use data encryption, file encryption,
and link encryption for strong security.
File encryption protects files in central servers and
mass storage devices from being read or changed
without an encryption key.

2. How Encryption For Strong Security
Works
2.An encryption program, usually in firmware,
uses a string of numbers called a key to create a
stream of data combining the real information with
a pseudorandom stream of bits. The real data is
buried i the pseudorandom “noise” . This is calld
data encryption.

3. How Encryption For Strong Security
Works
3.The PC's encrypted data, enclosed in
unencrypted TCP/IP and Ethernet packets,
crosses the network. Additionally, routers can
use encryption between themselves to protect the
entire stream of data. This is called link
encryption.

4.Local file encryption protects data from physical
intrusion.

5.VPN client software creates an encrypted tunnel
to the firewall/VPN server.
