Multi-constraint Security Policies for Delegated Firewall Administrationt layer that permits to define security policies independently of how they will be enforced. For example, the mandatory and security property polices could be assigned to the risk management staff while the discretionary policies could be delegated among the several departments in the organization.

Changes in the Web from 2000 to 2007 Aachen. The first trace was recorded in 2000, the other more than seven years later in 2007. We show the major differences, and the similarities, between the two traces and compare our observations with other work. The results indicate that traditional proxy caching is no longer effective in typical university networks.

SOON: A Scalable Self-organized Overlay Network for Distributed Information Retrieval semantic similarity defined, nodes are grouped accordingly, forming semantic virtual domains and clusters. Resource information integration and searching can be efficiently performed on top of this topology.

SYMIAN: A Simulation Tool for the Optimization of the IT Incident Management Process considering both the time spent by operators working on incidents and the time spent when waiting for operator’s availability. Experimental results show the SYMIAN effectiveness in the performance analysis and optimization of the incident resolution time for a fictitious organization designed according to real-life experiences.

Flexible Resolution of Authorisation Conflicts in Distributed Systemssimple override rules specified or selected by administrators. We demonstrate the capabilities of the approach by expressing the conflict resolution strategy for a moderately complex authorisation model that organises subjects and objects hierarchically.

Ensuring Collective Availability in Volatile Resource Pools Via Forecastinge data, we show how to reliably and efficiently predict that a collection of . hosts will be available for . time. The results indicate that by using replication it is feasible to deploy enterprise services or applications even on such volatile resource pools.

Dynamic Overlay Node Activation Algorithms for Large-Scale Service Deploymentsonditions change, additional nodes can be dynamically (de)activated. Our algorithms can be used in conjunction with existing overlay topology construction protocols..Through extensive simulations, we have evaluated and compared the performance of our algorithms.

Crawling Bug Tracker for Semantic Bug Searchug tracking systems and we describe how to crawl them in order to extract semi-structured data. We describe a unified data model to store bug tracking data. The model has been derived from the analysis of the most popular systems. Finally, we describe how the crawled data can be fed into a semantic search engine to facilitate semantic search.

Trust Management for Host-Based Collaborative Intrusion Detectionerimental results demonstrate that our system yields a significant improvement in detecting intrusions. The trust model further improves the robustness of the collaborative system against malicious attacks.
