- 5. About Oracle Database security Oracle Label Security secures database tables at the row level, allowing you to filter user access to row data based on privileges. Real Application Security Administration Console (RASADM) lets you create Real Application Security data security policies using a graphical user interface. Enterprise User Security addresses user, administrative, and security challenges by relying on the identity management services supplied by Oracle Internet Directory, an LDAP-compliant directory service. 5 Transparent Data Encryption enables you to encrypt data so that only an authorized recipient can read it. Oracle Data Redaction enables you to redact (mask) column data using several redaction types. Data Masking and Subsetting process of replacing sensitive data with fictitious yet realistic looking data and process of downsizing either by discarding or extracting data
- 6. continue Key Vault enables you to accelerate security and encryption deployments by centrally managing encryption keys, Oracle wallets, Java keystores, and credential files. Oracle Audit Vault and Database Firewall provides a comprehensive Database Activity Monitoring (DAM) solution that combines database audit logs with SQL traffic capture. 6 Database Assessment Tools Identify database configuration, operation, or implementation introduces risk. Database Vault restrict access to application data by privileged database users. Reducing the risk of insider and outside threats.
- 8. About Oracle Label Security ◉ controls the display of individual table rows using labels ◉ works by comparing the row label with a user's label authorizations to enable you to easily restrict sensitive information to only authorized users ◉ based on multi-level security (MLS) requirements ◉ installed by default, but not automatically enabled 8
- 9. Benefits of Oracle Label Security ◉ It enables row level data classification and provides out-of-the box access mediation based on the data classification and the user label authorization or security clearance. ◉ It enables you to assign label authorizations or security clearances to both database users and application users. ◉ It provides both APIs and a graphical user interface for defining and storing data classification labels and user label authorizations. ◉ It integrates with Oracle Database Vault and Oracle Advanced Security Data Redaction, enabling security clearances to be use in both Database Vault command rules and Data Redaction policy definitions. 9
- 10. Components of Oracle Label Security ◉ Labels: authorizations for users and program units, govern access to specified protected objects • Levels: indicate the type of sensitivity that you want to assign to the row • Compartments: represent the projects in this example that help define more precise access controls • Groups: identify organizations owning or accessing the data ◉ Policy: name associated with these labels, rules, authorizations, and protected tables 10

- 19. What is Auditing ◉ the monitoring and recording of selected user database actions, from both database users and nondatabase users ◉ The actions that you audit are recorded in either data dictionary tables or in operating system files 19
- 20. Why is Auditing Used ◉ Enable accountability for actions ◉ Investigate suspicious activity ◉ Notify an auditor of the actions of an unauthorized user ◉ Monitor and gather data about specific database activities ◉ Detect problems with an authorization or access control implementation 20
- 21. Types of Auditing Unified and Conditional Auditing ➢ Audit data managed using the built- in audit data management package within the database ➢ The AUDIT_ADMIN and AUDIT_VIEWER roles provides separation of duty ➢ Oracle audit vault and database firewall is integrated with this Traditional Database Auditing ➢ Prevent overhead on the source database system ➢ Be written to the operating system files as this configuration 21
