 Eleventh International Conference on Mobile Data Management (MDM '10).
-====== Web Crawlers Behaving Like Humans: Are We There Yet!?  ======
-**Supervisor**: Natalija Vlajic
-**Required Background**: CSE4480 prerequisites
-__Description__
-Distributed Denial of Service (DDoS) attacks are recognized as one
-of the most serious threats to today's Internet due to the relative
-simplicity of their execution and their ability to severely degrade
-the quality at which Web-based services are offered to the end users.
-An especially challenging form of DDoS attacks are the so-called
-Application-Layer DDoS attacks. Namely:
-  - In Application-Layer DDoS attacks, the attackers utilize a flood of legitimate-looking Layer-7 network sessions (i.e., sessions that are generally hard to detect and/or filter out by a firewall or an IDS system)
-  - Increasingly, these sessions comprise HTML requests generated by a cleverly programmed crawler that executes a semi-random walk over the web site links, thereby attempting to appear as a legitimate human visitor.
-The goal of this project is to investigate the state of the art in
-malicious web crawler design. In particular, the project will look
-into the challenges of designing a smart-DDoS-crawler from the
-attacker point of view - one of these challenges being the estimation
-of web-page popularity assuming no a priori access to the web-logs
-of the victim web-site.
