Intrusion Detection Systems (IDS) are very important in determining how secure a system is, and to discover several types of attack such as Denial of Service (DOS), Probes and User to Root (U2R) attacks. However, recently false alarm rates and accuracy of detection are happens to be the most important issues and challenges in designing effective IDS.(More)
Search stagnation is a serious problem that all Ant Colony Optimization (ACO) algorithms suffer from regardless of their application domain. The framework of Interacted Multiple Ant Colonies Optimization (IMACO) is a recent proposition. It divides the ants' population into several colonies and employs certain techniques to organize the work of these(More)
In recent years, web security has been viewed in the context of securing the web application layer from attacks by unauthorized users. The vulnerabilities existing in the web application layer have been attributed either to using an inappropriate software development model to guide the development process, or the use of a software development model that(More)
The approach of using multiple ant colonies is an extension of the Ant Colony Optimization framework. It offers a good chance to improve the performance of the ant algorithms by encouraging the exploration of a wide area of the search space without losing the chance of exploiting the history of the search. In this paper a new multiple ant colonies(More)
— Student's placement in industry for the practicum training is difficult due to the large number of students and organizations involved. Further the matching process is complex due to the various criteria set by the organization and students. This paper will discuss the results of a pattern extraction process using association rules of data mining(More)
The data warehouse (DW) systems design involves several tasks such as defining the DW schemas and the ETL processes specifications, and these have been extensively studied and practiced for many years. However, the problems in heterogeneous data integration are still far from being resolved due to the complexity of ETL processes and the fundamental problems(More)
Internet worms that spread autonomously from one host to another cause major problem in today's networks. On 25th January 2003, " Slammer " was released into the internet and after ten minutes the worm infected more than 90% of vulnerable hosts. Worms cause damage to the network by consuming its resources such as bandwidth. In this paper, we propose a(More)
One direction of ant colony optimization researches is dividing the ants' population into several colonies. These colonies work together to collectively solve an optimization problem. This approach offers good opportunity to explore a large area of the search space. This paper proposes a new generic algorithmic approach that utilized multiple ant colonies(More)
