Oracle Advanced Security provides a set of security features designed to secure databases and protect them from various security threats. These features aim to enhance data protection and ensure privacy and compliance with security regulations. Oracle Advanced Security includes a range of tools and techniques that focus on security at multiple levels.

Here’s an overview of some key features of Oracle Advanced Security:

1. Encryption:

• Data-at-Rest Encryption: Protects data stored on disks using encryption techniques, ensuring that the data is unreadable without the correct keys.
• Data-in-Transit Encryption: Protects data while it is being transmitted over networks using encryption protocols such as TLS (Transport Layer Security).

1. Access Control:

• Multi-Factor Authentication: Enhances security by requiring more than one method to verify users' identities.
• Fine-Grained Access Control: Allows for the implementation of precise access rules to control who can access different types of data and database operations.

1. Auditing and Monitoring:

• Auditing: Provides detailed logs of access operations and data modifications, aiding in the review of activities and identifying any unauthorized actions.
• Monitoring: Offers tools to monitor abnormal activities and help identify potential threats in real-time.

1. Data Masking:

• Data Masking: Protects sensitive data by replacing real information with fictitious or distorted values, ensuring data protection when used in non-production environments such as development and testing.

1. Administrative Security:

• Password Management: Includes advanced policies for managing passwords and specifying security requirements such as password length and complexity.
• Administrative Privilege Management: Ensures that access to sensitive commands and data is tightly controlled.

In simple terms, Oracle Advanced Security offers a comprehensive suite of tools and techniques to enhance the security of Oracle databases, ensuring data protection from threats and maintaining compliance with security policies and regulations.
