Performance Evaluation of Trust Based Access Control for XML Databases

چکیده
In order to improve security and provide dynamic access control for XML databases, we developed trust based access control for XML databases. Trust based access control for XML databases manages the access policy depending on users’ trustworthiness and prevents unauthorized processes, malicious transactions and misuse from both outsiders and insiders. Trust scores are updated on the basis of users’ histories. Privileges are automatically modified and adjusted over time depending on user behavior. In this paper, a practical trust based access control module for XML databases is evaluated. The dynamic access control has been tested from security, scalability, and performance perspectives. The experimental results illustrate the flexibility of trust values and the scalability of the system with small to large XML databases and with various numbers of users.

A Performance Evaluation of Logging in XML Databases Using an Xlog File for Trust Based Access Control
Logging is an important process in databases and is used for recovery and security purposes. Logging in XML databases has rarely been discussed in the literature. In this paper the Xlog file is presented as a dynamic and temporary log file for XML databases. It is used, not for recovery, but to calculate user trust values by recording users’ bad transactions and errors. The novelty in this appr...

The topic of enhancing security in XML databases is important as it includes protecting sensitive data and providing a secure environment to users. In order to improve security and provide dynamic access control for XML databases, we presented XLog file to calculate user trust values by recording users’ bad transaction, errors and query severities. Severity-aware trust-based access control for ...
متن کاملOn Effective Protection of Security and Privacy in XML Information Brokering
In contrast with the situations when the information seeker knows where the needed data is located, XML Information Brokering System (IBS) needs to help each information seeking query ”locate” the corresponding data source(s). Unlike early information sharing approaches that only involve a small number of databases, new information sharing applications are often assumed to be built atop a large...
متن کاملApply Uncertainty in Document-Oriented Database (MongoDB) Using F-XML
As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...
