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. The later chapters cover Oracle Vault, Oracle VPD, Oracle Labels, and Oracle Audit. Finally, in the Appendices, the book demonstrates how to perform a security assessment against the operating system and the database, and how to use a DAM tool for monitoring.

Using encryption with RMAN


Database backups also represent a very important area to be defended. Similarly with data pump dumps, backups made with RMAN can be encrypted and decrypted using encryption wallets. In this recipe we will enable RMAN encryption. We will also make a full backup followed by a restore. Next, we will save and delete the encryption wallet, and try a restore and recovery. We also emphasize the importance of saving these keys in a safe place.

Getting ready

All steps will be performed on nodeorcl1.

How to do it...

  1. Create a new directory to be used as the destination for future backups with the oracle user as the owner:

    mkdir –p / backup/rman
    chown oracle:oinstall /backup/rman
    
  2. Connect with RMAN and enable the encryption of backups for the database as follows:

    [oracle@nodeorcl1~] rman target / 
    
    RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON;
    
    new RMAN configuration parameters:
    CONFIGURE ENCRYPTION FOR DATABASE ON;
    new RMAN configuration parameters are successfully stored...
