<p> The global communication infrastructure of the Internet is formed by tens of thousands of Autonomous Systems connecting various organizations and individuals together. Having a global topology map of the Internet allows network researchers to understand the dynamics of the Internet in practice; guides network operators to enhance the reliability and security of their networks; allows network engineers to improve the efficiency of their systems; and helps developers to develop topology aware applications, among others. </p><p> In this dissertation, we study the implications of the Internet’s topological structure for its efficiency, security, and reliability. First, we developed a new mapping paradigm for the Internet’s topological structure: Cross-AS (X-AS) Internet topology mapping. Second, we developed a metric to identify the criticality of the autonomous systems in the Internet under targeted attacks. Next, we introduced a probabilistic packet marking defense framework against DoS attacks and the variants. Finally, we investigate the geographical properties of Internet routing.</p><p>
