1 Microsoft Security Development Lifecycle for IT Rob Labbé Security Engagement Manager MSIT Infosec – ACE

2 Microsoft IT Environment 94,000 Vista clients 48,000 Windows 7 clients 127,238 Office 2007 clients 129,000 Exchange 2007 mailboxes 359,000 SharePoint Sites MSCRM deployment for premier services business Dynamics business running on Dynamics products 5 data centers 9,700 production servers 108,000 servers (MSN) 98 countries 550 buildings 260,000+ SMS managed computers 585,000 devices 141,549 end users 2,400,000 internal e-mails with 18,000,000 inbound (97% filter rate) 36,000,000 IMs per month 136,000+ e-mail server accounts 137,000,000+ remote connections per month

3 Know Yourself, Know your Enemies “If you know your enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.” Sun Tzu, The Art of War “Hacking Microsoft UK”

4 The Reasons for Secure Software Data can be stolen by attackers Data can be corrupted by viruses Data can be lost or corrupted by employees IT Systems can be used by attackers To send Spam, viruses, or launch other attacks from IT Systems can be crashed by attackers There are many threats to data and systems

5 Application Layer = Weak Point Attackers target the weakest point. The OS Layer and Network layer are too hard now On Average over 70% of IT security budget is spent on Infrastructure, yet over 75% of attacks happen at the Application level According to Microsoft research, only 1/3 of developers are confident that they write secure code The focus must be on hardening the application layer

6 Reasons for IT Security Card Services - A Real World Example $10 Million a month in revenue Processed credit cards for American Express, Master Card, and VISA They Lost 40 Million records to hacking Government imposed heavy fines Subject to audits every 6 months for 20 years Amex, Master Card and Visa dropped them A $10 Million a month company destroyed

7 Understanding The Attackers

8 Author Script-Kiddie Hobbyist Hacker Expert Specialist Vandal, Cyberpun k Thief,Booster,Fence, Classic Criminals Spy,Terrorist Mal-TechTrespasser National Interest, Chaos Steal Something of Value / assets Personal Fame, To Embarrass, To Win Curiosity Nothing Anyone Un-intentional Disgruntled Employee

9 Hackers are very smart

10 We need better security

11 Implement an SDL Implement an SDL to build security into your development process Train your developers in secure coding techniques Incorporate Threat Modeling, Secure Code Review, Security Focused Testing into the process

12 Purpose of the SDL Inventory and assess applications Identify and ensure resolution of security/privacy vulnerabilities found in those applications Enable Application Risk Management: Strategic Tactical Operational Legal

13 The SDL is NOT Optional At Microsoft all line-of-business application teams must go through SDL-IT, All shrink-wrapped products must go through the SDL If they fail to do so, they cannot go into production Enforcement of the SDL-IT process attributes to it’s success

14 Visibly Measure the Process Have internally visible score cards Have contests to see if you can find bugs and offer prizes Offer incentives to teams with the best security records (no cheating!)

15 SDL aligns with SDLC SDLC SDL-IT Envision Application Entry / Risk Assessment Threat Model / Design Review Design Internal Review Develop / Purchase Pre-Production Assessment TestRelease / Sustainment Post- Production Assessment

16 Application Entry / Risk Assessment Objective: Application Inventory Determine Application Risk Categorization High Risk Security/Privacy Release Medium Risk Security/Privacy Release Low Risk Security/Privacy Release Threat Model / Design Review Internal Review Pre-Production Assessment Post-Production Assessment App Entry

17 Threat Model / Design Review Objective: Threat modeling provides a consistent methodology for objectively evaluating threats to applications. Review application design to verify compliance with security standards and best practices Verify application meets application principles Confidentiality Integrity Authentication Authorization Availability Non-repudiation Threat Model / Design Review Internal Review Pre-Production Assessment Post-Production Assessment App Entry

18 Internal Review Review security checklist/policy site Team conducts ‘self’ code review and attack and penetration testing Threat Model / Design Review Internal Review Pre-Production Assessment Post-Production Assessment App Entry

19 Pre-Production Assessment Objective: Low Risk Applications Host Level Scan Windows IIS SQL High/Medium Risk Applications Host Level Scan White Box Code Review Threat Model / Design Review Internal Review Pre-ProductionAssessment Post-Production Assessment App Entry

20 White Box Code Review Process Application team provides source code Analysts review application code uncovering security vulnerabilities Vulnerabilities logged in bug database Application team required to address all sev 1 bugs prior to going into production

21 Some common attack patterns white box review may reveal Cross-Site Script Vulnerabilities SQL Injection Buffer Overflow Poor Authorization Controls Secrets Stored In Clear Text

22 Post-Production Assessment Objective: High/Medium/Low Risk Applications Host Level Scan Windows IIS SQL Threat Model / Design Review Internal Review Pre-Production Assessment Post-ProductionAssessment App Entry

23 Conclusion The need for security is obvious, we have to protect the company and our customers To do that we need Management Support Secure Development Life Cycles Developers trained in secure development A Security First attitude!

24 Conclusions Continuous improvement of the process Invest time in upfront activities: Threat Modeling Design Reviews A holistic view People Process Tools It may seem hard to get started – ask for help! People: Providing guidance on secure application development Tools: Providing the most innovative tools Process: Security cannot be an afterthought

25 Call To Action Implement a Secure Development Lifecycle Create more secure and reliable software Build Trust!
