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.

Integrating Oracle audit with SYSLOG


By using a standard audit, the resulting audit trails can be tampered with or deleted by database administrators or by an attacker who gained administrative privileges. This is a considerable security risk. SYSLOG is a protocol (RFC5424) designed for transmitting event messages and alerts across an IP network. The messages are generated, for example, by an application (ftp, cron, or ssh), and a syslog daemon catches them and integrates them using a device or another remote daemon. In this recipe we will integrate the Oracle audit trails with rsyslog.

Getting ready

All steps will be performed on the nodeorcl1 and HACKDB database.

How to do it...

  1. Integration with syslog requires the destination of audit trails to be placed externally. Change the audit trail to OS as follows:

    SQL> alter system set audit_trail=OS scope=spfile;
    
    System altered.
    
  2. rsyslog is a more advanced variant of syslog and is the default in Red Hat 6. The configuration file is /etc/rsyslog...
