Identity and Security in the Cloud
- 3. Cyber Threats …no longer just an IT issue. • Average time attackers stay in a network before detection is over 200 days • Over 75% of all network intrusions are traced back to compromised credentials • Average cost of a data breach to a company is $3.5 million • Estimated cost of cybercrime to the global economy is $500 billion
- 4. Motivations • Enforcement of social or political points of view • To gain long term trusted access to internal resources • Information • Compute power and bandwidth • Obtain credentials for access to other services • Extortion by means of • Business systems interruption • Threatening individuals privacy • or discrediting the organisation
- 5. Cyber Threats …there are 2 types of organisations affected: Those that don’t know it (yet) Those that have been breached
- 6. Changing nature of Cyber Attacks Attacks and threats have grown substantially more sophisticated, frequent and severe. In the vast majority of attacks, they compromise user credentials and use legitimate IT tools instead of malware. We are now working under the assumption that we are already breached
- 8. 5 Key Recommendations Amit Yoran, RSA President 1. Even advanced protection can fail 2. We need pervasive and true visibility of everything 3. Identity and Authentication matter more than ever • Don’t trust the trusted, protect them! 4. Don’t mistake a malware solution for an Advanced Threat Strategy 5. Use external Threat Intelligence Reports
- 9. What REALLY matters? Brand • Trustworthiness Reputation • Availability • Reliability Credibility • Accreditation Financials • Cost to prevent • Cost to repair
- 10. What needs protection? •Logon credentials •Gaining trusted access •Across all entities Identity •Infrastructure – admin, service, and system accounts •high costs to repair in both time and materials •Use MFA and education! Resources •Privileged access to sensitive information •DLP helps classified/controlled, information •What about the rest? Information •Documents at rest, in transit, or shared externally •Encryption is the minimal level for everythingData
- 11. HOW? Protect Education and vigilance is key Layered approach Technology and People Detect Understand the scenarios Look for anomalies Test regularly Analyse Know the scale of the problem Identify the potential impact Protect the logs and other information Respond Don’t react hastily, follow a plan Call in the experts, including the lawyers if necessary Communicate clearly, but securely
- 12. Identity Management • Know who your people are and centralise management of Identities: • Administrators and trusted authorities • Insiders • Externals • Implement good housekeeping • Ensure training for security and privacy at all levels • Monitor behaviours and regulate access permissions • Implement key policies: • Pin locks • Passwords • Multi-Factor authentication
- 13. Application and Device Management Management based on characteristics: • Ownership • Support/Management • Level of trust • Device standards and capabilities • Location and usage scenario
- 14. Data Security Enable key features where possible: • Full drive encryption • Data replication services • Invest in Information Rights Management and Data Loss Prevention for the most sensitive information
- 15. Wheretostart?
- 17. Multi-Factor Authentication Enable/Enforce MFA to end-users Will enforce App Passwords for rich clients that don t support MFA - Office 2013 (can preview ADAL) - Office 2010 - Skype for Business - OneDrive for Business - Mail apps on smartphones Multi-Factor Authentication Second Factor options: - Mobile app (online and OTP) - Phone Call - SMS Application passwords Default Microsoft greetings Office 365 / Azure Administrators Fraud alert One-Time Bypass Custom greetings/caller ID Caching Trusted IPs MFA SDK Security Reports MFA for on-premises apps Block/Unblock Users Event Confirmation Azure AD Premium additional features
- 18. Access Control Service Enables the use of multiple IdPs to provision access to SaaS applications • Integrated Single Sign On • Claims-based access control • Centralised authorization into web applications • Google, Yahoo!, Facebook, etc. • Available in Basic and Premium
- 20. Azure Rights Management Enable control of data beyond your security boundary • Limit access to known identities • Monitor, track, change permissions in-flight • Company policy templates, automated application, individual control
- 21. Protect a document and share
- 22. Customer registration and download
- 23. Track & Revoke
- 24. Track & Revoke
- 25. Resources • Protecting Azure Blob Storage with Azure RMS Whitepaper http://blogs.msdn.com/b/rms/archive/2014/05/27/protecting-azure-blob-storage-with-azure-rms-whitepaper.aspx • Information Protection and Control (IPC) in Office 365 with Microsoft Rights Management service (RMS) whitepaper http://www.microsoft.com/en-us/download/confirmation.aspx?id=34768 • Official RMS Team blog http://blogs.technet.com/b/rms/ • RMS Analyzer Tool http://blogs.technet.com/b/rms/
- 26. Azure Security Center Currently in public preview: • Advanced Threat Analytics – global scale • Security monitoring and auditing • Threat detection and alerts • Hadoop cluster ingests massive quantities of data from security feeds • Machine Learning and Real People! (cyber security teams and partnerships) • In partnership with the major industry security vendors • Integrates with existing security solutions (SIEM)
- 27. Cloud Access Security Broker Adallom: recently purchase by Microsoft • Centralised AuthN/AuthZ for all cloud application • Agentless, flexible deployment options • Integrated with solutions like CheckPoint, SIEM, DLP and MDM
- 28. Advanced Threat Analytics Focus on what’s important, fast • Malicious attack detection • Alerts for known security issues and risks • Analysis for abnormal behaviour using machine learning
- 29. ATA: Pass-The-Hash Demo • Our bad guy is DodgyUser, he’s managed to get access to a PC and running his tools…. • Our good guy is MarketingUser, he’s logged on to this pc and carrying out his work normally • DodgyUser is able to enumerate all users logged on, and obtain the HASH of their password:
- 30. ATA: Pass-The-Hash Demo • With this information, DodgyUser can now switch to use these credentials on any machine and perform operations as that user
- 31. ATA: Pass-The-Hash Demo • ATA was watching:
- 32. ATA: Alerts
- 33. ATA: Alerts
- 34. Coming soon… Administrative Units BYO SaaS Applications Pwd rollover for FB, Twitter and Linked In Dynamic group membership Conditional Access – per app Privileged Identity management Self-service app requests Azure reporting API Cloud Access Security Broker (Adallom?)
- 35. Windows 10 • 110 million activations in just 2 months ! • Deploy without re-imaging the device • Windows Hello & BitLocker • Registered hardware can be 2nd factor for sign-in to all services • Separation of business and personal information • Same experience on Phone as on Desktop • Enterprise containerisation with Hyper-V • Universal App Store – with employee store experience
- 36. Actions & Resources • Start using MFA for all your personal accounts • Consider security at the beginning of Solution Development • Look for and highlight any risks or concerns at your customer • Join the discussion on our Yammer group Security • Use the Cloud Roadmap diagrams to explore solutions and options • Use this deck, works well on mobile Share the message, raise awareness
- 37. Thank you ! Richard Diver @rdiver

- Layered security, protection and isolation When we look the way we have been building security over the last 10 years, it has been focused on a “Defence In Depth” approach: protecting assets, data and identities at multiple levels through our IT infrastructure. This has worked well when we had control of our infrastructure and knew where the boundaries were.
- Previously we only had to worry about our data centres, networks, and managed devices. Now we have BYOD, Social Networking, Work-from-anywhere, and apps that we have little control over, or zero visibility. The landscape has changed, and our approach to protection has to change also: we need new strategies and new tools
- Some worrying facts – you might not know you are being attacked until its already too late. Source: https://www.microsoft.com/en-us/server-cloud/products/advanced-threat-analytics/#Fragment_Scenario2

- Assume Breached – this is rapidly being adopted as the security industry standard approach – go hunting for vulnerabilities, check in on trusted solutions to ensure they are being used appropriately, and by the right people, and protect the most vulnerable accounts (those that will do the most damage if compromised).
- Unfortunately the bad guys are winning, and there is no sign of the breaches reducing, only getting worse. Unless we do something about it !
- Source: Escaping Security’s Dark Ages https://www.youtube.com/watch?v=op-2Aj6Wizo For every solution ask: “how does this really help?” True visibility requires control over IDENTITY. Everywhere. Focus on what is important and identify threats quicker
- Brand: It takes years to build the trust, but only takes a simple mistake to break it Reputation: doing what you say you are going to do, being predictable and reliable Financials: Cost to prepare, or cost to repair (some pay the ransom)
- To protect our most trusted identities we can deploy technologies that utilise behavioural analytics and machine learning to identify changes in behaviour and unusual activity, 24/7 We also need to deploy MFA and most importantly educate our users.
- MFA is available for all Azure Administrators and all Office 365 subscription users. When enabled for Azure AD Premium, additional functionality is available.
