Zusammenfassung der Kapitel (Chapter Summaries)
- Part 1: This section focuses on practical exercises related to steganography, digital watermarking, and data protection policies. It includes a detailed analysis of a proposed steganography method and suggests improvements for enhancing security. It also demonstrates how to implement a data protection report for a school, addressing key considerations like confidentiality and access rights for different staff roles.
- Part 2: This section delves into database security, covering essential concepts like database authentication, authorization, and data integrity. It explores the use of data dictionary for user information, creating new user accounts, managing password policies, and assigning profiles. Furthermore, it demonstrates the practical implementation of privileges and roles for different users, including the creation of roles and assignment of permissions for specific tasks. The labs also cover implementing data integrity constraints using table creation and data manipulation. The final lab delves into virtual private databases (VPD) and how to implement fine-grained access control using VPD and application context. It explains the use of SYS_CONTEXT function to retrieve application context information and how to apply security policies for different user roles.
