DNSSEC extends DNS with a public-key infrastructure, providing compatible clients with cryptographic assurance for DNS records they obtain, even in the presence of an active network attacker. As with many Internet protocol deployments, administrators deciding whether to deploy DNSSEC for their DNS zones must perform cost/benefit analysis. For some fraction of clients — those that perform DNSSEC...

The Resource Public Key Infrastructure (RPKI) binds IP address blocks to owners’ public keys. RPKI enables routers to perform Route Origin Validation (ROV), thus preventing devastating attacks such as IP prefix hijacking. Yet, despite extensive effort, RPKI’s deployment is frustratingly sluggish, leaving the Internet largely insecure. We tackle fundamental questions regarding today’s RPKI’s dep...

Organizations spend a major portion of their Information Technology budget on software maintenance. In this paper, we present a predictive model for the maintenance outcomes of the software projects. We also identify the factors that affect software maintenance outcomes. We build our model using Data Mining (DM) techniques on Open Source Software (OSS) project data. We use the public access to ...

Business intelligence approaches are standard in private organisations. In public administrations, however, only first steps towards such intelligent managing support are undertaken. Deficits become apparent especially in the move of implementing new public management approaches, such as new accounting systems or an output-oriented management. While public administrations are often obliged to i...
