This paper studies two types of events that often overload Web sites to a
point when their services are degraded or disrupted entirely --- flash events
(FEs) and denial of service attacks (DoS). The former are created by
legitimate requests and the latter contain malicious requests whose goal is to
subvert the normal operation of the site. We study the properties of both
types of events with a special attention to characteristics that distinguish
the two. Identifying these characteristics allows a formulation of a strategy
for Web sites to quickly discard malicious requests. We also show that some
content distribution networks (CDNs) may not provide the desired level of
protection to Web sites against flash events. We therefore propose an
enhancement to CDNs that offers better protection and use trace-driven
simulations to study the effect of our enhancement on CDNs and Web sites.
