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.
