Oracle Database 12c Security Cookbook
Oracle Database 12c Security Cookbook
Welcome to the Oracle Database 12c Security Cookbook! In this article, we will explore various techniques and best practices to enhance the security of your Oracle Database 12c. With the increasing number of cyber threats, it is crucial to protect your valuable data from unauthorized access and potential breaches. This cookbook will provide you with step-by-step instructions and practical examples to secure your database effectively.
Chapter 1: Securing User Accounts
1.1 Creating Strong Password Policies
One of the fundamental aspects of database security is enforcing strong password policies. By setting up complex password requirements, you can ensure that user accounts are protected against brute-force attacks. This section will guide you through the process of creating and implementing robust password policies.
1.2 Implementing Two-Factor Authentication
Adding an extra layer of security to user authentication is essential in today’s digital landscape. Two-factor authentication provides an additional level of protection by requiring users to provide a second form of verification, such as a fingerprint or a one-time password. This section will demonstrate how to enable and configure two-factor authentication for your Oracle Database 12c.
Chapter 2: Data Encryption
2.1 Encrypting Data at Rest
Encrypting data at rest ensures that even if an attacker gains unauthorized access to the physical storage media, they won’t be able to read the sensitive information. This section will walk you through the process of implementing data encryption at rest using Oracle Transparent Data Encryption (TDE).
2.2 Securing Data in Transit
Securing data while it is being transmitted over the network is crucial to prevent eavesdropping and data interception. This section will explain how to enable and configure Secure Sockets Layer (SSL) encryption for your Oracle Database 12c, ensuring that all data sent between the client and the server is encrypted.
Chapter 3: Auditing and Monitoring
3.1 Enabling Database Auditing
Enabling auditing allows you to track and monitor all activities performed on your Oracle Database 12c. This section will guide you through the process of enabling and configuring database auditing, ensuring that you have a comprehensive audit trail for compliance and security purposes.
3.2 Monitoring Database Activity
Monitoring database activity in real-time is essential to detect and respond to potential security incidents promptly. This section will introduce you to various tools and techniques for monitoring database activity, including Oracle Enterprise Manager and third-party monitoring solutions.
