7. Security & Compliance Control Objectives
• Control Objective 1: Security Organization
– Who we are
– Proper control & access within the organization
• Control Objective 2: Amazon User Access
– How we vet our staff
– Minimization of access
8. Security & Compliance Control Objectives
• Control Objective 3: Logical Security
– Our staff start with no systems access
– Need-based access grants
– Rigorous systems separation
– Systems access grants regularly re-evaluated & automatically
revoked
9. Security & Compliance Control Objectives

issues
11. Shared Responsibility
• Let AWS do the heavy lifting
• This is what we do – and we do it all the time
• As the AWS customer you can focus on your business and not be
distracted by the muck

12. Physical Security
• Large non-descript facilities
• Robust perimeter controls
• 2 factor authentication for entry
• Controlled, need-based access for AWS employees
• All access is logged and reviewed
14. Network Security
• DDoS attacks defended at the border
• Man in the Middle attacks
• SSL endpoints
• IP Spoofing prohibited
• Port scanning prohibited
• Packet Sniffing prevented
15. Amazon EC2 Security
• Host operating system
– Individual SSH keyed logins via bastion host for AWS admins
– All accesses logged and audited
• Guest operating system
– Customer controlled at root level
– AWS admins cannot log in
– Customer-generated keypairs
• Stateful firewall
– Mandatory inbound firewall, default deny mode
• Signed API calls
– Require X.509 certificate or customer’s secret AWS key

18. VPC - Dedicated Instances
• Option to ensure physical hosts are not shared with other
customers
• $10/hr flat fee per Region + small hourly charge
• Can identify specific Instances as dedicated
• Optionally configure entire VPC as dedicated
19. • Customers have requirements that require them to use specific
encryption key management procedures not previously
possible on AWS
– Requirements are based on contractual or regulatory mandates for keeping
encryption keys stored in a specific manner or with specific access controls
– Good key management is c
• Customers want to run applications and store data in AWS but
previously had to retain keys in HSMs in on-premises
datacenters
– Applications may slow down due to network latency
– Requires several DCs to provide high availability, disaster recovery and durability of
keys
Customer Challenge: Encryption
20. • AWS offers several data protection mechanisms including access
control, encryption, etc.
• AWS data encryption solutions allow customers to:
– Encrypt and decrypt sensitive data inside or outside AWS
– Decide which data to encrypt
• AWS CloudHSM complements existing AWS data protection and
encryption solutions
• With AWS CloudHSM customers can:
– Encrypt data inside AWS
– Store keys in AWS within a Hardware Security Module
– Decide how to encrypt data – the AWS CloudHSM implements cryptographic functions and
key storage for customer applications
– Use third party validated hardware for key storage
• AWS CloudHSMs are designed to meet Common Criteria EAL4+ and FIPS 140-2 standards)

21. • Customers receive dedicated access to HSM appliances
• HSMs are physically located in AWS datacenters – in close network
proximity to Amazon EC2 instances
• Physically managed and monitored by AWS, but customers control
their own keys
• HSMs are inside customer’s VPC – dedicated to the customer and
isolated from the rest of the network
What is AWS CloudHSM?
AWS CloudHSM
22. • Secure Key Storage – customers retain control of their own keys and
cryptographic operations on the HSM
• Contractual and Regulatory Compliance – helps customers comply
with the most stringent regulatory and contractual requirements for key
protection
• Reliable and Durable Key Storage – AWS CloudHSMs are located
in multiple Availability Zones and Regions to help customers build
highly available applications that require secure key storage
• Simple and Secure Connectivity – AWS CloudHSMs are in the
customer’s VPC
• Better Application Performance – reduce network latency and
increase the performance of AWS applications that use HSMs
