Özet:

Cloud computing and systems are very popular in today’s Information Technology and Systems and have grown extremely. Cloud computing helps organizations solve increasing IT costs such as their licenses,power consumption,physical protection,by providing better standardization,higher benefit,greater performance,and quick responses of information services. This thesis presents the study of ensuring database security in cloud computing, protecting data especially from internal attacks, and managing high volumes of log data. Security requirements of a network system differ from each other according to the system which you are using. Carrying vital importance for our private and secret information, cloud systems must provide extra security solutions for database systems with the organizations. While using firewalls, intrusion detection systems on the network for external attacks, improved access controls must be thought for internal attacks. Using database actions logs and audit can be very helpful on developing a database protection system. However, storing these logs will cause a storage and performance problem. The other problem is to manage many databases at the same time. This system provides managing many databases at the same time from the same place. Logs from each database is transmitting to the central point asynchronously. Administrating database protection solution from a central point in cloud helps us to manage security of databases and handling huge volumes of data.The performance of our proposed system has been evaluated against one of the most commonly used products on the market, Oracle audit Vault Server and better results have been obtained on some topics in this thesis.
