10. Less responsibilities

11. More responsibilities
Less responsibilities

12. Options : Responsibilities

13. Re:Boot

14. Critical embargoed bug discovered in Xen, details at h‫מּ‬p://4mn.ca/1rcXTTN

15. A small percentage on instances scheduled for a reboot

16. ACTIONS TO TAKE
From AWS’ Mark Ryland talk at h‫מּ‬p://4mn.ca/ZZeDbA
Nothing for cloud-native architectures
Manage availability
For EC2
Nothing for Multi-AZ instances
Standard maintenance window for
single instances
For RDS

17. POODLE

18. CVE-2014-3566 : Padding Oracle On Downgraded Legacy Encryption

19. A‫מּ‬ack forces an older cipher choice. Details at h‫מּ‬p://4mn.ca/1EYfBEA

20. ACTIONS TO TAKE
From AWS’ Mark Ryland talk at h‫מּ‬p://4mn.ca/ZZeDbA
Select a non-affected cipher suite
For ELB
Enable TLS_FALLBACK_SCSV
Disable support for SSL 3.0*
For Web Servers

(){}; attacka:() { b; } | a‫מּ‬ack;

24. ACTIONS TO TAKE
Update bash
Use an intrusion prevent system
For EC2

25. Applied at the boundary
Majority of security controls are traditionally applied at the boundary

26. Same controls applied in the AWS Cloud, now to each instance
Applied to each instance
