  1. Using the Cloud and SaaS to Secure the SDLC

  2. About Me Andy Earle • HP/Fortify • Security Solutions Architect / Presales Engineer • Sell, deliver solutions to commercial and US Fed • Past • PM for High Assurance computer system at BAE • Mobile and App Security, multiple jobs • Software Engineer, multiple jobs

  3. Agenda • Terms and Background • Application Security (AppSec) Deployment Models • SaaS / Cloud (On Demand) • On-Premise • AppSec Industry Evolution • Relevant Trends • Case for “Hybrid” Implementation • Hybrid On-Premise / cloud delivery of S-SDLC

  4. Terms and Background • Terms • SaaS : Software as a Service • SDLC : Software Development Lifecycle • SSA : Software Security Assurance • Background • Focus is static analysis…but many concepts applicable to dynamic • SaaS and (public) cloud somewhat interchangeable, for this session • Caveats: Lots of variety of offerings amongst vendors; many of my statements are necessarily generalities

  5. AppSec Deployment Models

  6. What is SaaS? Software as a Service (SaaS) …or Security as a Service, in the AppSec world • SaaS is a delivery model where software, data and services are hosted in the cloud and delivered on demand • Application Security SaaS offerings include • Static, dynamic, and manual analyses • Expert review and prioritization of results • Various delivery offerings (web interface, reports, artifacts that integrate with onsite infrastructure)

  7. AppSec via SaaS 1 SaaS Web Portal 4 2 Stakeholders Analysis SaaS Process, On-Demand Deliver code or bytes Analysis as a Service Expert Review Results made available 3 AppSec SME - review & triage Dev Org

  8. What is an SDLC? Software Development Lifecycle (SDLC) …or Secure Development Lifecycle …or Secure Software Dev Lifecycle (S-SDLC) S-SDLC incorporates security across all phases of the development lifecycle. Security is built into applications from the start. Result: Software Security Assurance (SSA)

  9. Sample Secure SDLC Check in Code IDE Plug-in Check-out, Build and Scan Build Machine Developer Fixes Bug / Security Finding Possibly Continuous Integration Repeat as Necessary Bug Tracking Vulnerability Scan Submit Findings to Bug Tracker Auditor / Security PM / Tech Lead Auditor Reviews Results On Premise Deployment Code Repository Developers

  10. Building Security into an SDLC Build Security in: Activities & Tasks • Developer & staff training • Vulnerability analysis technologies • Technology integrations and automation • AppSec processes, procedures and metrics • Governance, enforcement of the above …Basically, process reengineering …This is SSA

  11. SSA Challenges Challenges to implementing an SSA program • Tools “wanted by security, need to be used by development” • Developers not security trained. Security doesn’t understand source code • Seamless integration of security requires big upfront commitment • Expertise is scarce (and expensive in time or $$$) • And more…

  12. SaaS vs. On-Premise

  13. The Strengths ofSaaS and On-Premise Pure SaaS Deployment • Easy and cost effective to get started • Little to no expertise required • Findings make case for future appsec investments • Meet compliance and reporting obligations Pure On-Premise Deployment • Better model for “The Fix” • Addresses the systemic problem • Integration and automation maximize efficiency

  14. A Solid Plan for SSA Phase 1: Pure SaaS • Assess Critical Apps • Prioritize and secure funding for Phase 2 • Train and/or hire resources • Fix critical vulnerabilities, low hanging fruit Phase 2: Pure On-Premise • Bring technology and expertise in-house • Solve the systemic problem – reduce repeat vulnerabilities • Integration and automation maximize efficiency • Mature SSA program • This could include putting SaaS onsite (private cloud)

  15. How things are Evolving

  16. Relevant AppSec Trends People • Developers are increasingly security trained and aware • AppSec SMEs more prevalent, many in the solution providers and security firms Product • Applications increasingly complex • Hardware and time to analyze steepening • Increased expertise required to scan accurately • SaaS increasingly integrate-able with onsite systems Process • Compliance obligations mandating S-SDLC

  17. S-SDLC Baseline Deployment Check in Code Check-out, Build and Scan Developer Fixes Bug / Security Finding Build Machine Possibly Continuous Integration Repeat as Necessary Bug Tracking Vulnerability Scan Submit Findings to Bug Tracker Auditor / Security Auditor Reviews Results Basic, On Premise Code Repository Developers

  18. S-SDLC Needs • Analysis Needs: • Power, processing, memory • Multiple servers • Expertise to scan accurately • Development Needs: • Security, vulnerability training • IDE integration of results • Low impact to current processes Vulnerability Scan • Auditor Needs: • Deep appsec knowledge • Expertise with scanning tool • Knowledge of app deployment = SaaS Auditor / Security = On Premise Developers

  19. SaaS Integration Points Check in Code Check-out, Build and Scan Developer Fixes Bug / Security Finding Build Machine or Continuous Integration Repeat as Necessary Bug Tracking Vulnerability Scan Submit Findings to Bug Tracker Auditor / Security Auditor Reviews Results On Premise Infrastructure Code Repository Developers

  20. SaaS Integration Points Build Machine or Continuous Integration SaaS Bug Tracking • Point & click • Automated • Web-based Auditor / Security PM / Tech Lead On Premise Infrastructure Code Repository Developers

  21. Bringing it all Together • Key Concepts in a Hybrid S-SDLC Deployment • Expertise available via SaaS is typically superior to that found on-premise (they are the experts) • Some tasks require on-site activity (like fixing bugs) • Disruptions to existing processes can slow adoption; start small and build slowly • Integration points can blur the on-premise / on-demand separation, facilitating adoption

  22. Hybrid Delivered Secure SDLC Triggered Check-out Check in Code IDE Plug-in Continuous Integration Developer views bugs & findings Triggered send for Analysis Dev loads issues in IDE Plug-in Bug Tracking SaaS • Analyze/Scan • Expert Review Submit Findings to Bug Tracker Auditor / PM Download, Prioritize Results Hybrid Deployment Code Repository Developers

  23. Integration Points Lots of opportunity for customization and fitting the deployment model to the customer environment

  24. Plan for SSA, Revisited Phase 1: Pure SaaS • Assess Critical Apps • Prioritize and secure funding for Phase 2 Phase 2: On-Premise Pilot and SaaS • Continue SaaS regime • Deploy on-premise technology, design and test long term processes • Train and/or hire resources • Fix critical vulnerabilities, low hanging fruit Phase 3: Hybrid On-Premise and SaaS Deployment • Deploy more technology and expertise in-house • Difficult apps (for example) are still analyzed, triaged via SaaS • Integration and automation max efficiency across deployments • Mature SSA program

  25. Final Thoughts • Take advantage of expertise where it resides, potentially buying time to bring it in-house • The general maturity curve is still on-demand --> on-premise • Automated or easy integrations are vital to successful hybrid deployment • Plan! Think long term. • Sometimes a pure on-premise or on-demand deployment is still the best answer. The important thing is to fit the solution to the problem and need.
