Security is one of the most important topic for 2023 and 2024. It will keep to be important for us. Because data is important, data is private and data is the biggest value for our centure.

So what Oracle offers to us to protect our data for any internal or external attacks.

Oracle has several products and features designed to enhance the security of Oracle Database environments.

One of the primary Oracle security products is Oracle Advanced Security (OAS).

Here’s an overview:

1. Oracle Advanced Security (OAS): OAS is a comprehensive security solution for Oracle Database environments. It provides various features and functionalities to protect data, prevent unauthorized access, and ensure compliance with regulatory requirements. Some key features of Oracle Advanced Security include:

• Transparent Data Encryption (TDE): TDE enables encryption of sensitive data stored in Oracle Database tablespaces, data files, and backups, protecting data at rest from unauthorized access.
• Data Redaction: OAS includes data redaction capabilities that allow sensitive data to be masked or partially concealed from users who do not have the appropriate privileges, helping to prevent unauthorized access to sensitive information.
• Secure Sockets Layer (SSL)/Transport Layer Security (TLS): OAS supports SSL/TLS encryption for securing network communication between Oracle Database clients and servers, ensuring data privacy and integrity during transit.
• Secure Authentication: OAS provides support for strong authentication mechanisms such as Kerberos, PKI (Public Key Infrastructure), and smart cards, enhancing the security of user authentication processes and preventing unauthorized access.
• Network Encryption: OAS encrypts data transmitted over the network between Oracle Database clients and servers, protecting data in transit from eavesdropping and interception.

In addition to Oracle Advanced Security, Oracle Database also includes various built-in security features and capabilities to address different aspects of database security:

• Authentication and Authorization: Oracle Database supports multiple authentication methods, including password-based authentication, external authentication, and strong authentication mechanisms such as PKI and Kerberos. It also provides robust authorization mechanisms, including role-based access control (RBAC) and fine-grained access control (FGAC), allowing administrators to define and enforce access policies based on user roles and privileges.
• Auditing and Compliance: Oracle Database includes comprehensive auditing capabilities to monitor and record database activity, including user logins, data access, and administrative actions. Administrators can configure auditing policies to capture specific types of events and generate audit trails for compliance with regulatory requirements such as GDPR, HIPAA, and PCI DSS.
• Data Masking and Subsetting: Oracle Database offers data masking and subsetting features that allow organizations to obfuscate sensitive data in non-production environments, reducing the risk of data breaches and unauthorized access during development, testing, and training activities.
• Database Vault: Oracle Database Vault is an additional security layer that provides fine-grained access controls and privileged user management capabilities. It helps organizations restrict access to sensitive data and critical database operations, reducing the risk of insider threats and unauthorized access.
