  4. 4. The Inevitable Questions Privacy What does privacy at Microsoft mean? Are you using my data to build advertising products? Compliance What certifications and capabilities does Microsoft hold? How does Microsoft support customer compliance needs? Do I have the right to audit Microsoft? Transparency Where is my data? Who has access to my data ? Security Is cloud computing secure? Are Microsoft Online Services secure?
  5. 5. The World is changing • • • • • • • • Telecoms Advancements Consumerization of mobile devices Lower costs in hardware Cheap low cost storage Massive growth in virtualization Low Cost Software development Easier support / licensing models Elasticity & Scalability
  6. 6. The World is changing • Product is evolving into a Service • Focus is moving from “location or Work place” to “Any location” • Huge growth in BYOD • Users will consume data rather than use a specific device to access it • New administration & management models. E.g. RBAC, federation • Will bring new security challenges
  7. 7. Microsoft Cloud “Trusted Service” 4 core trust pillars Your Privacy Matters Leadership in Transparency Independently Verified Relentless on Security We respect your privacy You know ‘where’ data resides, ‘who’ can access it, and ‘what’ we do with it Compliance with World Class Industry standards verified by 3rd parties Excellence in cutting edge security practices
  8. 8. Cloudthat this is a two-way trust Principles Understand
  9. 9. Understand that Microsoft’s liability is capped Consistent with industry standard. Microsoft’s liability is capped at 12 months’ services fees. Liability represents aggregate amount. Liability is limited to direct damages.
  10. 10. First things first - Risk Risk Management is the name given to a logical and systematic method of identifying, analyzing, treating and monitoring the risks involved in any activity or process. It is also a methodology that helps managers make best use of their available resources
  11. 11. The threat landscape is changing • Increased number of malicious threats have increased • Bot’s, Spam, Viruses, Trojans • Enterprise software costs very expensive, licensing complex • Government snooping fears* • Cybercrime now big business
  12. 12. Cloud Considerations • • • • • Customer Accountability Multi-tenancy Different responsibilities Trust Operational support Vs Service support
  13. 13. Protecting Data • All data & PPI must be protected against: – – – – – Disclosure Destruction Interruption Modification Theft • This requires the organization to create operational, technical, and physical controls to address information protection for both local & hosted stored data.
  14. 14. Microsoft’s Data Centre Locations
  15. 15. Transparency The Microsoft strategy is to consistently set a “high bar” around privacy practices that support global standards for data handling and transfer Where is Data Stored? Clear Data Maps and Geographic boundary information provided ‘Ship To’ address determines Data Center Location Who accesses and What is accessed? Core Customer Data accessed only for troubleshooting and malware prevention purposes Core Customer Data access limited to key personnel on an exception basis. How to get notified? Microsoft notifies you of changes in data center locations.
  16. 16. Data Storage & Access • Microsoft offers transparency around location of customer data • Microsoft adhere to the requirements from the strictest markets, like the EU Data Protection Directive, so that it can legally store and use data in compliance with legal requirements • Microsoft tracks major international privacy laws so we know what is coming and are ready to address it
  17. 17. Role-Based Access Control Who What Role groups define highlevel job functions Where Assign task-, action-, or feature-based permissions End-user role assignment policies for self-service Systems Administrator Human Resources Compliance Officer Delegate multiple roles Limit the scope of the role assignment; e.g., “Legal Department” or “Asia Offices Help Desk
  18. 18. RBAC for Office 365 Operations Lock Box: Role Based Access Control O365 Admin Requests Access Logged as Service Request 1. Auditable 2. Available as self-service reports Grants temporary Privilege Office 365 Datacenter Network 20 Grants least privilege required to complete task. Verify eligibility by checking if 1. Background Check Completed 2. Fingerprinting Completed 3. Security Training Completed Corporate Network
  19. 19. Office 365 operations model evolution 24x7 Product Team Operations Product Team Product Team • Direct escalations • Operations applied to specific problem spaces (i.e., deployment) • Emphasize software and automation over human processes Other • Tier 1 used for routing/escalation only • 10-12 engineering teams provide direct support of service Engineered Operations Support • Tiered IT • Progressive escalations (tier-totier) • “80/15/5” goal Direct Support Operations • Highly skilled, domain specific IT (not true Tier 1) • Success depends on static, predictable systems Service IT Product Team Traditional IT Tier 2 Operations Tier 1 Operations Service Tier 1 Operations Software Aided Processes Service Service Service

  24. 24. The Snowden Effect!
  25. 25. Privacy
  26. 26. Privacy in Office 365 At Microsoft, our strategy is to consistently set a “high bar” around privacy practices that support global standards for data handling and transfer No Advertising No advertising products out of Customer Data. No scanning of email or documents to build analytics or mine data. Data Portability Office 365 Customer Data belongs to the customer. Customers can export their data at any time. No Mingling Choices to keep Office 365 Customer Data separate from consumer services.
  27. 27. Microsoft: We use customer data for just what they pay us for - to maintain and provide Office 365 Service Microsoft Online Services Customer Data1 Usage Data Account and Address Book Data Customer Data (excluding Core Customer data) Core Customer Data Operating and Troubleshooting the Service Yes Yes Yes Yes Security, Spam and Malware Prevention Yes Yes Yes Yes Improving the Purchased Service, Analytics Yes Yes Yes No Personalization, User Profile, Promotions No Yes No No Communications (Tips, Advice, Surveys, Promotions) No No/Yes No No Voluntary Disclosure to Law Enforcement No No No No Advertising5 No How Privacy of Data is Protected?

  28. 28. Government Subpoenas • Will Microsoft turn over my data to US companies or the US government? – Microsoft believes customers should control their own information – When compelled by U.S. law enforcement to produce customer records, Microsoft will first attempt to redirect these demands to the customer – Microsoft will notify the customer unless it cannot, either because Microsoft is unable to reach the customer or is legally prohibited from doing so – Microsoft will only produce the specific records ordered by law enforcement and nothing else • Your organization is most likely already exposed to government jurisdiction; therefore, for many companies, moving to the cloud doesn’t represent a huge increase in risk
  29. 29. Compliance
  30. 30. Compliance management framework Policy Control Framework Standards Business rules for protecting information and systems which store and process information A process or system to assure the implementation of policy System or procedural specific requirements that must be met Step-by-step procedures Operating Procedures
  31. 31. Office 365 Compliance & Standards ISO 27001 International Standards & Controls Data Processing Agreement SSAE 16 (Statement on standards for Attestation Engagement) SOC 1 (Type I & Type II) compliance All Customer Industry Specific Compliance & Standards FISMA US Government HIPAA/BAA Healthcare Customers FERPA EDU Customers Geography Specific Standards EU Safe Harbor EU Model Clauses Full details available at: Microsoft Office 365 Trust Center EU Customers
  32. 32. Addressing Audit Concerns • Microsoft offers: – Alignment and adoption of industry standards – Comprehensive set of practices and controls in place to protect your data – Focus on solutions for millions of users worldwide – Independent third party attestations of Microsoft security, privacy, and continuity controls • This allows Microsoft Online to provide assurances to customers at scale
  33. 33. Auditing on Your Behalf • Alignment and adoption of industry standards ensure a comprehensive set of practices and controls in place to protect sensitive data • While not permitting audits, we provide independent third-party verifications of Microsoft security, privacy, and continuity controls. This saves customers time and money, and allows Microsoft to provide assurances to customers at scale
  34. 34.

  36. 36. Limitations of Windows AD • • • • • • • • • Directory service implemented on MS domain networks Introduced in Windows 2000 DCs authenticate and authorise users and computers in a domain Assigns and enforces security policies Deployed in a single domain nor as part of a larger forest Can be expanded through Trust Relationships Has both physical & logical attributes Only one instance per domain Active Directory uses LDAP, Kerberos, and DNS
  37. 37. WAD: Potential Issues • As a number of trust limitations in respect to size & complexity • Designed primarily to manage in-house networks • Protocol limitations i.e. LDAP • Customer security concerns about WAD data in cloud (closed attributes) • Does not natively support new cloud based protocols • Solution: Extend AD attributes into cloud…
  38. 38. What is Windows Azure Active Directory? • Customized Version of ADLDS / ADAM • Every Office 365 Customer is an Azure AD Tennant • Designed primarily to meet the needs of cloud applications • Extends Customers Active Directory into the cloud • Think of it as a Fish on a Hook! • Identity as a service: essential part of Platform as a Service
