Enquadramento
Data Warehouses (DWs) store sensitive data that encloses many business secrets. They have become the most common data source used by analytical tools for supporting decision making in most enterprises. This makes them an extremely appealing target for both inside and outside attackers. Given these facts, securing them against data damage and information leakage is critical.
In order to guarantee that data is not accessed by others, mechanisms have to be added that are very expensive in terms of processing. Preventive data security techniques are used for protecting data in advance of attacks, such as data access policies, data masking and encryption techniques for changing original data values, and checksums for integrity checks on changed data.
In this internship, we propose and test solutions to optimize scalability and data security in Big Data Warehouses. On one hand, we need to investigate the use of a set of security techniques, such as encryption, masking, anonymity and access control.
Objetivo
In practice, the expected outcomes of this internship are:
- Develop privacy and security techniques for Big Data Warehouses.
- Provide data warehousing scalability for the cloud, while incorporating privacy and security concerns.
- Evaluate the use of secure and scalable approaches for transactional and analytical data management needs of companies.
- A research paper, to be submitted and presented at a top international conference, describing the approach and main results obtained from the experiments.
