Database security

Security Enhanced Applications for Information Systems. In recent years, with the frequent occurrence of security incidents, enterprises and organizations have now realized the importance of designing a safety information system. Today, information systems are heavily relied on web and database technologies, thus the risks and threats those technologies faced will also affect the security of information systems. Web and database security technologies can ensure the confidentiality, integrity and usability of data in information system, and can effectively protect the security and reliability of information system. Therefore, in order to better secure the information systems, we need to learn Web and database security-related knowledge. This chapter covers extensively practical and useful knowledge of web and database security. This chapter can be divided into three parts: advanced security threats, the principles of safety design and safety audit; Advanced security threats section contains cross-site scripting XSS attacks, AJAX and SQL injection attacks and other security threats, which will be presented in detail; the principles of safe design section describe the general safety design principles to help design information systems security; last section describes the manual and automatically audit methods, and general security audit framework to help readers to understand more clearly.

Web and Database Security

Database security entails allowing or disallowing user actions on the database and the objects within it. Oracle uses schemas and security domains to control access to data and to restrict the use of various database resources. Oracle provides comprehensive discretionary access control. Discretionary access control regulates all user access to named objects through privileges. A privilege is permission to access a named object in a prescribed manner; for example, permission to query a table. Privileges are granted to users at the discretion of other users.

Database security concerns the use of a broad range of information security controls to protect databases potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links against compromises of their confidentiality, integrity and availability. Ross J. Anderson has often said that by their nature large databases will never be free of abuse by breaches of security; if a large system is designed for ease of access it becomes insecure; if made watertight it becomes impossible to use. This is sometimes known as Anderson's Rule. Databases have been largely secured against hackers through network security measures such as firewalls , and network-based intrusion detection systems.


Here we will focus on the Authorization and Access control aspects. Page 2. Database Users. • Most commercial DBMS include a security subsystem that manages.


Database security

The types of database security measures your business should use include protecting the underlying infrastructure that houses the database such as the network and servers , securely configuring the DBMS, and the access to the data itself. Database security encompasses multiple controls, including system hardening, access, DBMS configuration, and security monitoring. These different security controls help to manage the circumventing of security protocols.
