In this paper, we propose a method to analyze the firewall policy or rule-set using Relational Algebra and Raining 2D-Box Model. It can discover all the anomalies in the firewall rule-set in the format that is usually used by many firewall products such as Cisco Access Control List, IPTABLES, IPCHAINS and Check Point Firewall-1. While the existing analyzing methods consider the anomalies betwee...

The literature has argued that developing countries are unable to adopt counter-cyclical monetary and fiscal policies due to financial imperfections and unfavorable politicaleconomy conditions. Using a world sample of 115 industrial and developing countries for 1984-2008, we find that the level of institutional quality plays a key role in countries' ability to implement counter-cyclical macroec...
