AWS Summit 2014 Brisbane - Breakout 1

The AWS cloud infrastructure has been architected to be one of the most flexible and secure cloud computing environments available today. In this session, we’ll provide a practical understanding of the assurance programs that AWS provides; such as HIPAA, FedRAMP(SM), PCI DSS Level 1, MPAA, and many others. We’ll also address the types of business solutions that these certifications enable you to deploy on the AWS Cloud, as well as the tools and services AWS makes available to customers to secure and manage their resources.

Presenter: Stephen Quigg, Solutions Architect, APAC, Amazon Web Services

  2. 2. Our customers have different viewpoints on security PR Keep out of the news! CEO Protect shareholder value CI(S)O Preserve the confidentiality, integrity and availability of data
  3. 3. Security is always our number one priority at AWS PEOPLE & PROCEDURES NETWORK SECURITY PHYSICAL SECURITY PLATFORM SECURITY Comprehensive Security Capabilities to Support Virtually Any Workload
  4. 4. SECURITY IS SHARED
  5. 5. WHAT NEEDS TO BE DONE TO KEEP THE SYSTEM SAFE
  6. 6. WHAT WE DO WHAT YOU HAVE TO DO
  7. 7. EVERY CUSTOMER HAS ACCESS TO THE SAME SECURITY CAPABILITIES CHOOSE WHAT’S RIGHT FOR YOUR BUSINESS
  8. 8. AWS SECURITY OFFERS MORE VISIBILITY AUDITABILITY CONTROL
  9. 9. MORE VISIBILITY
  10. 10. CAN YOU MAP YOUR NETWORK? WHAT IS IN YOUR ENVIRONMENT RIGHT NOW?
  11. 11. TRUSTED ADVISOR
  12. 12. MORE AUDITABILITY
  13. 13. SECURITY CONTROL OBJECTIVES 1. SECURITY ORGANIZATION 2. AMAZON USER ACCESS 3. LOGICAL SECURITY 4. SECURE DATA HANDLING 5. PHYSICAL SECURITY AND ENV. SAFEGUARDS 6. CHANGE MANAGEMENT 7. DATA INTEGRITY, AVAILABILITY AND REDUNDANCY 8. INCIDENT HANDLING
  14. 14. AWS CLOUDTRAIL
  15. 15. You are making API calls... On a growing set of services … CloudTrail is continuously recording API calls… And delivering log files to you
  16. 16. Security analysis Use log files as an input into log management and analysis solutions to perform security analysis and to detect user behavior patterns. Track changes to AWS resources Track creation, modification, and deletion of AWS resources such as Amazon EC2 instances, Amazon VPC security groups and Amazon EBS volumes. Troubleshoot operational issues Quickly identify the most recent changes made to resources in your environment. Compliance and audit aid Easier to demonstrate compliance with internal policies and regulatory standards.
  17. 17. ‣  CloudTrail records API calls and delivers a log file to your S3 bucket. ‣  Typically, delivers an event within 15 minutes of the API call. ‣  Log files are delivered approximately every 5 minutes. ‣  Multiple partners offer integrated solutions to analyze log files, including Splunk, SumoLogic and Loggly
  18. 18. Amazon CloudWatch Logs can monitor your system, application and custom log files from Amazon EC2 instances and other sources, for example: Monitor your web server http log files and use CloudWatch Metrics filters to identify 404 errors and count the number of occurrences within a specified time period CloudWatch Alarms can then notify you when the number of 404 errors breaches whatever threshold you decide to set – you could use this to automatically generate a ticket for investigation Now monitor everything with CloudWatch logs
  19. 19. MORE CONTROL
  20. 20. Defense in Depth Multi level security •  Physical security of the data centers •  Network security •  System security •  Data security DATA
  21. 21. AWS Security Delivers More Control & Granularity Choose what’s right for your business needs AWS CloudHSM Defense in depth Rapid scale for security Automated checks with AWS Trusted Advisor Fine grained access controls Server side encryption Multi-factor authentication Dedicated instances Direct connection, Storage Gateway HSM-based key storage AWS IAM Amazon VPC AWS Direct Connect AWS Storage Gateway
  22. 22. AWS EMPLOYEE ACCESS ‣  Staff vetting ‣  No logical access to customer instances ‣  Control-plane access limited and monitored Bastion hosts, Least privileged model, Zoned data center access ‣  Access based on strict business needs ‣  Separate PAMS
  23. 23. Every network has fine-grained security control built-in AvailabilityZoneA AvailabilityZoneB You control your VPC address range •  Your own private, isolated section of the AWS cloud •  Every VPC has a private IP address space you define •  Create your own subnets and control all internal and external connectivity AWS network security •  AWS network will prevent spoofing and other common layer 2 attacks •  Every compute instance gets multiple security groups - stateful firewalls •  Every subnet gets network access control lists
  24. 24. Control firewalls for every host with security groups VPC A - 10.0.0.0/16 AvailabilityZoneA 10.0.1.0/24 10.0.2.0/24 10.0.3.0/24 EC 2 10.0.5.0/24 Jump 10.0.4.0/24 EC 2 App “Web servers will accept Port 80 from load balancers” “App servers will accept Port 8080 from web servers” “Allow SSH access only from from Jump Hosts” Log EC 2 Web Load balancing
  25. 25. Control traffic between each subnet with NACLs VPC A - 10.0.0.0/16 AvailabilityZoneA 10.0.1.0/24 10.0.2.0/24 10.0.3.0/24 EC 2 10.0.5.0/24 Jump 10.0.4.0/24 EC 2 App Log EC 2 Web “Deny all traffic between the web server subnet and the database server subnet” Load balancing

  32. 32. You can stay onshore in Australia if you need to AWS Sydney Region Multiple availability zones
  33. 33. MFA DELETE PROTECTION
  34. 34. YOU CAN ENCRYPT ALL OF YOUR DATA CHOOSE WHAT’S RIGHT FOR YOU Automated – AWS manages encryption Enabled – user manages encryption using AWS Client-side – user manages encryption their own way
  35. 35. ENCRYPT YOUR SENSITIVE DATA AWS CLOUDHSM AMAZON S3 SSE AMAZON GLACIER AMAZON REDSHIFT AMAZON RDS
  36. 36. Managed and monitored by AWS, but you control the keys Increase performance for applications that use HSMs for key storage or encryption Comply with stringent regulatory and contractual requirements for key protection EC2 Instance AWS CloudHSM AWS CloudHSM You can store your encryption keys in AWS CloudHSM
  37. 37. CONTROL WHO CAN DO WHAT WITH YOUR AWS ACCOUNT
  38. 38. Control access and segregate duties everywhere With  AWS  IAM  you  get  to  control  who  can  do   what  in  your  AWS  environment  and  from  where     Fine-­‐grained  control  of  your  AWS  cloud  with  two-­‐ factor  authen<ca<on     Integrated  with  your  exis<ng  corporate  directory   using  SAML  2.0  and  single  sign-­‐on   AWS account owner Network management Security management Server management Storage management
  39. 39. AWS IAM: Recent innovations Securely control access to AWS services and resources •  Delegation –  Roles for Amazon EC2 –  Cross-account access •  Powerful integrated permissions –  Resource level permissions: Amazon EC2, Amazon RDS, Amazon DynamoDB, AWS CloudFormation –  Access control policy variables –  Policy Simulator –  Enhanced IAM support: Amazon SWF, Amazon EMR, AWS Storage Gateway, AWS CloudFormation, Amazon Redshift, Elastic Beanstalk •  Federation –  Web Identity Federation –  AD and Shibboleth examples –  Partner integrations •  Strong authentication –  MFA-protected API access –  Password policies •  Enhanced documentation and videos

  41. 41. You get to do all of this in DEVELOPMENT TESTING PRODUCTION
  42. 42. Expand your skills with AWS Certification aws.amazon.com/certification Exams Validate your proven technical expertise with the AWS platform On-Demand Resources aws.amazon.com/training/ self-paced-labs Videos & Labs Get hands-on practice working with AWS technologies in a live environment aws.amazon.com/training Instructor-Led Courses Training Classes Expand your technical expertise to design, deploy, and operate scalable, efficient applications on AWS
