DNS fragmentation attacks - the dangers of not validating DNSSEC Men and Mice
How to prevent DNS fragmentation attacks on your network. DNS cache poisoning attacks can, and have been used, to redirect traffic within networks and are often the first step for larger attacks.
Learn:
- why DNS fragmentation attacks work
- why DNS caching servers that do not do DNSSEC validation are especially vulnerable
- why DNSSEC signed zones can be used to launch this attack
- how IPv6 and/or DNSSEC validation can stop these attacks

This paper investigates the relationship between tax structures and economic growth in a panel of developed and developing countries, using the new ICTD GRD. It sought to understand the effects of tax structure on GDP growth, since many previous studies have only focused on OECD countries.
It is also motivated by the IMF Policy prescription (IMF 2011), of on-going shift from reliance on trade taxes to VAT, especially in low income countries. It further sought to understand the implications of such structural shifts with studies showing that revenue recovery following trade liberalisation has been poor in low- and middle- income countries (Baunsgaard & Keen, 2010).
Results suggest that shifts away from trade and consumption toward income taxes have had a negative impact on GDP growth rates in developing countries. This negative effect is of greater magnitude through personal income taxes (PIC). Consequently, this study provides new evidence of potentially harmful effect of trade liberalisation on the GDP growth rates. The study also gives a clear picture of low tax reliance on indirect taxes between in low-income countries.
Revenue neutral shifts away from trade taxes to consumption taxes have no negative effect on growth. However, revenue neutral shifts towards income, specifically personal income taxes are potentially harmful to GDP growth rates. Key findings hold following the exclusion of resource-rich countries and after controlling for degree of openness.
