As a result of research combined with increases in computing capacity, computer security has reached what many consider to be. Database and application security form one end of the computer security field. These two areas are closely aligned because of the heavy and obvious relationship between applications and databases. Creating a sound and secure (database) application is challenging not just...

14 Part I: Oracle Database Security New Features. For a single application, for example, it’s not uncommon to see base tables in one schema, code in another schema, and metadata or summary data in a third schema. Isolating these might allow procedural code updates to the code schema to be done without significant (if any) impact on the other schemas....

This chapter defines only what you need to know to make the critical decisions about how and when to use encryption within the database.. The proven part is important because it ensures that the encryption doesn’t have some fatal flaw that would allow an unauthorized person to determine the contents of the sensitive data.

You can think of the Oracle Wallet as secure container used to store authentication and signing credentials. These credentials may take the form of certificates needed for Secure Sockets Layer (SSL), Public Key Infrastructure (PKI) private keys, or a TDE Master Key. When the wallet is used to store the TDE Master Key, it’s called an encryption wallet. Then you...

Column-level TDE encrypts and decrypts data at the SQL level, making it transparent to the end user. As a result, several database features that access data at the kernel level are incompatible with column-level TDE. These limitations disappear with tablespace encryption available in 11g, as you will see in the next section.. Another potential drawback in TDE’s column-based encryption is...

Keys themselves are never removed from the device in an unencrypted form, and the table keys are sent to the HSM device for decryption over a secure channel. Including a vendor-specific library to the host operating system accomplishes the implementation of an HSM device.:. The directory (/opt/oracle) is important: it must exist (create one if it doesn’t, and make sure...

Note that it’s not the fact that a data field value changed, but what the change in the value meant.. If you simply look at it from a statement-by-statement level, all you may see in the audit logs are a bunch of INSERT, UPDATE, and DELETE statements. It all depends on the context of the update.. (This is precisely why...

Connection_Type Identity Authentication_Method Client_IP Session_User. The approach to identifying factors based on the identity of other factors requires the following steps:. The factor that is identified by other factors is called the parent factor.. Define the identities...
