Oracle Database 23ai introduces advanced security features designed to enhance data protection, simplify configurations, and align with modern security standards. These updates strengthen the database’s security posture and improve usability for administrators and developers. Let’s dive into some of the key security enhancements in Oracle 23ai:
1. TLS 1.3 Support and Simplified Configuration
Oracle Database 23ai now supports TLS 1.3, the latest version of the Transport Layer Security protocol, ensuring stronger encryption and improved performance for secure communications. Additionally, the configuration process for TLS between the server and client has been streamlined, making it easier to implement and manage secure connections.
2. Extended Password Length Support
Security starts with robust authentication. Oracle 23ai now supports passwords up to 1024 bytes in length, allowing organizations to enforce more complex and secure password policies. This enhancement significantly reduces the risk of brute-force attacks and strengthens access controls.
3. Granular Control Over Read-Write Operations
A new feature in Oracle 23ai enables administrators to control whether a user or session can perform read-write operations, regardless of the user’s privileges. This provides fine-grained control over database activities, helping to prevent unauthorized modifications and ensuring compliance with security policies.
4. Introduction of DB_DEVELOPER_ROLE
Oracle 23ai introduces a new role, DB_DEVELOPER_ROLE, specifically designed for application developers. This role adheres to the principle of least privilege, granting developers only the permissions necessary for their tasks. By minimizing unnecessary access, this feature reduces the attack surface and enhances overall security.
5. Extended Data Dictionary Protection
Oracle has expanded its data dictionary protection to include non-SYS Oracle schemas such as Sysbackups, Syskm, Sysrac, and Sysdg. This extension ensures that critical metadata is safeguarded across a broader range of system schemas, further securing the database environment.
6. Simplified Certificate Management
Starting with Oracle 23ai, the database client no longer requires a wallet to store well-known CA root certificates on various platforms, including Linux, non-Linux, and Windows. If these certificates are available locally, the database can utilize them directly, simplifying certificate management and reducing administrative overhead.
7. Deprecation of Traditional Auditing and Case-Insensitive Passwords
Oracle 23ai marks the end of support for traditional auditing and case-insensitive passwords. These changes reflect Oracle’s commitment to modernizing its security framework and encouraging the adoption of more robust and standardized practices.
8. Uniform FIPS 140 Configuration
Oracle 23ai introduces the FIPS_140 parameter, enabling organizations to configure FIPS (Federal Information Processing Standards) compliance consistently across multiple database environments and features. This ensures a standardized approach to meeting regulatory and security requirements.
Conclusion
Oracle Database 23ai brings a host of security enhancements that address both emerging threats and evolving compliance needs. From stronger encryption protocols to granular access controls and simplified configurations, these features empower organizations to build more secure and resilient database environments. Whether you’re an administrator, developer, or security professional, Oracle 23ai provides the tools you need to stay ahead in today’s dynamic cybersecurity landscape.
