Overview of this book

For almost all organizations, data security is a matter of prestige and credibility. The Oracle Database is one of the most rich in features and probably the most used Database in a variety of industries where security is essential. To ensure security of data both in transit and on the disk, Oracle has implemented the security technologies to achieve a reliable and solid system. In Oracle 11g Anti-Hacker's Cookbook, you will learn about the most important solutions that can be used for better database security."Oracle 11g Anti-hacker's Cookbook" covers all the important security measures and includes various tips and tricks to protect your Oracle Database."Oracle 11g Anti-hacker's Cookbook" uses real-world scenarios to show you how to secure the Oracle Database server from different perspectives and against different attack scenarios. Almost every chapter has a possible threads section, which describes the major dangers that can be confronted. The initial chapters cover how to defend the operating system, the network, the data and the users. The defense scenarios are linked and designed to prevent these attacks.

Using encryption with data pump

Table or full database dumps can also be a major source of information theft in case it is not protected. Oracle also provides encryption options for data pump exports using TDE or passwords. In this recipe we will generate dumps by exporting the HR schema using different encryption options. Next, we will import each dump by remapping the tablespace USERS to the tablespace ENCRYPTED_TBS, and using related options.

Getting ready

All steps will be performed on the database HACKDB.

How to do it...

  1. Create a directory /security/datapump for dumps and change its ownership to the user oracle:

    mkdir –p /backup/datapump
    chown oracle:oinstall /backup/datapump
  2. Connect as the user system and create an oracle directory mapped to the /backup/datapump directory by executing the following statement:

    SQL> create directory encrypted_dumps as '/storage/datapump';
    Directory created.
  3. Export the schema HR by using the all option and the encryption mode transparent as follows...
