Key features for enabling a more secure Oracle Net include use of
encryption services such as RSA Data Security??™s RC4, the U.S. Data Encryption
Stanadard (DES), Triple DES, and the Advanced Encryption Standard (AES).
Authentication can be through Kerberos, RADIUS, or the Distributed Computing
Environment (DCE). Network data integrity checking uses MD5 or SHA-1. Oracle
Database 11g added enhanced transparent data encryption and expanded Kerberos
authentication leveraging of Oracle??™s encryption types.
Label Security Option
Oracle Label Security controls access to data by comparing labels assigned to rows of
data with label authorizations granted to users through their privileges. Multiple
authorization levels are possible within a single database. Label security authorizations
are managed through a Policy Manager. Policies are enforced in the database
instead of through views, thus greatly simplifying management of data accessibility
and providing a more secure implementation.
Database Vault Option
Oracle Database Vault Option provides fine-grained access control to data for everyone
with access to the database, including database administrators.
