  1. Hey, You, Get Off of My Cloud Thomas Ristenpart, EranTromer, HovavShacham, Stefan Savage Presented by Daniel De Graaf

  2. Cloud Computing • Virtual Machines with Dynamic Allocation • Amazon EC2 • Microsoft Azure • RackspaceMosso • Trusted provider, untrusted clients

  3. Attacks on the Cloud • Targeted attacks • Hypervisor compromise • Denial of Service • Information leakage • Most need attacker’s and victim’s VM to be on the same physical host

  4. Cloud Cartography • Mapping current and future allocations • Dynamic allocation • Current systems have high placement locality • Overall success of 40% for a given target

  5. Attacks on Co-Resident VMs • Information leakage • Disk I/O (access time) • CPU usage (cache timings) • Network traffic rate (latency and/or bandwidth) • Critical information leak • SSH keystroke timings
