Solving Security Challenges with Oracle Advanced Security
Introduction to Oracle Advanced Security 1-5
Data Encryption
Sensitive information that travels over enterprise networks and the Internet can be
protected by encryption algorithms. An encryption algorithm transforms
information into a form that can be deciphered with a decryption key.
Figure 1–1 shows how encryption works to ensure the security of a transaction. For
example, if a manager approves a bonus, this data should be encrypted when sent
over the network to avoid eavesdropping. If all communication between the client,
the database, and the application server is encrypted, then when the manager sends
the bonus amount to the database, it is protected.
