Cloud Security is:• Universal• Visible• Auditable• Transparent• Shared• Familiar
Universal Cloud SecurityEvery Customer Has Access to the Same Security Capabilities, and Gets to Choose What’s Right for Their Business• Governments• Financial Sector• Pharmaceuticals• Entertainment• Start-Ups• Social Media• Home Users• Retail
Visible Cloud Security
AWS allows you to see your en#re infrastructure at the click of a mouse. Can you map your current network?

Auditable Cloud SecurityHow do you know AWS is right for your business?
- 3rd Party Audits• Independent auditors
- ArCfacts• Plans, Policies and Procedures
- Logs• Obtained• Retained• Analyzed
Transparent Cloud SecurityChoose the audit/certification that’s right for you:• ISO-27001• SOC-1, SOC-2• FedRAMP• PCI
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
Security & Compliance Control Objectives
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
Security & Compliance Control Objectives
Control Objective 4: Secure Data Handling• Storage media destroyed before being permitted outside our datacenters• Media destruction consistent with US Dept. of Defense Directive 5220.22
Control Objective 5: Physical Security and Environmental Safeguards• Keeping our facilities safe• Maintaining the physical operating parameters of our datacenters
Security & Compliance Control Objectives
Control Objective 6: Change Management• Continuous Operation
Control Objective 7: Data Integrity, Availability and Redundancy• Ensuring your data remains safe, intact & available
Control Objective 8: Incident Handling• Processes & procedures for mitigating and managing potential issues
Shared Responsibility• Let AWS do the heavy liIing• This is what we do – and we do it all the Cme• As the AWS customer you can focus on your business and not be distracted

Network Security
• DDoS attacks defended at the border• Man in the Middle attacks• SSL endpoints• IP Spoofing prohibited• Port scanning prohibited• Packet Sniffing prevented
Amazon EC2 SecurityHost 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
Amazon Virtual Private Cloud (VPC)• Create a logically isolated environment in Amazon’s highly scalable infrastructure
• Specify your private IP address range into one or more public or private subnets
• Control inbound and outbound access to and from individual subnets using stateless Network Access Control Lists
• Protect your Instances with stateful filters for inbound and outbound traffic using Security Groups
• Bridge your VPC and your onsite IT infrastructure with an industry standard encrypted VPN connection and/or AWS Direct Connect
Amazon 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
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 critical
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
• AWS offers several data protection mechanisms including access control, encryption, etc.
• 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 Data Protection Solutions
HSM – Hardware Security Module• A hardware device that performs cryptographic operations and key storage • Used for strong protection of private keys • Tamper resistant – keys are protected physically and logically
– If a tampering attempt is detected, the appliance destroys the keys • Device administration and security administration are logically separate
– Physical control of the appliance does not grant access to the keys • Certified by 3rd parties to comply with government standards for physical and
logical security: – FIPS 140-2 – Common Criteria EAL4+
• Example vendors include: SafeNet, Thales • Historically located in on-premises datacenters
HSM
What is AWS CloudHSM?
• 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
AWS CloudHSM
AWS CloudHSM Service Highlights• 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
• Large Silicon Valley company: video DRM
• Start-up document rights management service: enterprise document protection• Amazon Web Services: Root of trust for Public Key Infrastructure (PKI)
authentication system• Very large financial services organization: Root of trust for key management
system for virtual machine authentication & encryption

On-Premises Integration with AWS CloudHSM
HSM
Customers’ applications continue to use standard crypto APIs (PKCS#11, MS CAPI, JCA/JCE, etc.).
SafeNet HSM client replaces existing crypto service provider libraries and connects to the HSM to implement API calls in hardware
SafeNet HSM Client can share load and store keys redundantly across mulCple HSMs
Key material is securely replicated to HSM(s) in the customer’s datacenter
