No Followers? No Botnet? No Problem! Asymmetric Denial of Service Attacks - HT-107

Bryan Sullivan, Senior Program Manager, Microsoft Corporation

Facing increasingly tougher privilege escalation defences, cybercriminals and “hacktivists” are moving to highly efficient and effective asymmetric denial of service tactics – in some cases, taking out entire server farms with a single HTTP request. This session will explore the code and design flaws behind some of the newest and deadliest of these application-level DoS vulnerabilities.

Bryan Sullivan is a Senior Security Program Manager at Microsoft, where he focuses on cloud security issues.
