Oracle Data Redaction
Oracle Data Redaction dynamically masks data during query execution, protecting sensitive information from unauthorized access. The primary role of data redaction is to mask column data based on specific policies, controlling how data is displayed without modifying the actual stored data.
Data redaction policies are highly configurable, allowing organizations to define how and when data should be redacted based on user privileges and other conditions. This flexibility makes sensitive information visible only to authorized users, minimizing the risk of exposure.
Several types of data redaction can be enforced within the Oracle Advanced Security landscape, including full redaction, partial redaction, regular expressions, random redaction, or no redaction at all. These options equip organizations to effectively protect sensitive data while maintaining database usability and accessibility.
Network Encryption
Network encryption is another critical feature of Oracle Advanced Security, ensuring that the data transmitted over existing networks remains secure. Oracle Advanced Security uses Oracle Net native encryption and Secure Sockets Layer (SSL) to protect data during transmission. These encryption methods prevent unauthorized interception and tampering of data packets as they travel across network connections.
The Secure Sockets Layer (SSL) in Oracle Advanced Security secures network connections through user authentication, data encryption, and maintaining data integrity. SSL can utilize digital certificates (X.509 v3) and public/private key pairs for system and user authentication, providing a robust and flexible security solution.
SSL can be configured for server authentication only, client authentication only, or both, based on the organization’s security needs. This flexibility lets organizations tailor network encryption strategies to meet specific needs, keeping data secure during transmission.
Enhancing Data Privacy and Integrity
Enhancing data privacy and integrity is a crucial aspect of any organization’s data security strategy. Oracle Advanced Security provides features that help organizations comply with critical regulations such as GDPR and HIPAA, ensuring that sensitive data is properly protected.
Data Privacy Measures
Oracle Advanced Security supports Advanced Encryption Standard (AES) with key lengths of 128-bit, 192-bit, and 256-bit, operating in outer Cipher Block Chaining (CBC) mode. This robust encryption standard ensures that sensitive data is protected from unauthorized access. It also offers two- and three-key versions of Triple-DES, with performance heavily dependent on the processor’s speed.
RC4 is another high-speed encryption algorithm supported by Oracle Advanced Security, which operates with variable key lengths, making it ideal for optimizing large data transfers. Transparent Data Encryption (TDE) specifically protects sensitive data from threats such as ransomware and unauthorized OS-level access.
Oracle Advanced Security uses network encryption and SSL to secure data transmission. These methods help organizations meet compliance requirements for regulations like PCI DSS, offering a comprehensive approach to data privacy and security.
Ensuring Data Integrity
Maintaining data integrity is vital for trust in an organization’s data. Oracle Advanced Security utilizes MD5 and SHA algorithms to ensure data integrity during transmission. These algorithms generate checksums that change whenever data is altered, allowing for the detection of any modifications.
Threats like data tampering by malicious third parties can compromise data integrity. Transactions can be intercepted and rerouted in distributed environments, posing significant risks to data integrity. Connections can be hijacked, leading to uncertainty regarding the authenticity of the client and server.
SHA is slower but more secure compared to MD5 in cryptographic strength. By using cryptographically secure message digests, Oracle Advanced Security helps maintain data integrity throughout its transmission, ensuring the data remains accurate and trustworthy.
