26. REALITY  CHECK   Security  &  Elements  of  ConsideraJon  
27. Secure  Code  vs.  Secure  So6ware   Fixing  a  single  security  bug   Ensuring  no  criQcal  bugs  are   introduced  to  so]ware  
28. Secure  Code  vs.  Secure  So6ware   Fixing  a  single  security  bug   •  While  moving  fast   •  With  minimal  impact  to   developers   •  Within  an  agile  or  constant   deployment  model   •  Across  thousands  of   developers,  mulJple  sites   and  services,  and  numerous   new  lines  of  code   Ensuring  no  criQcal  bugs  are   introduced  to  so]ware  
29. Secure  Code  vs.  Secure  So6ware   Fixing  a  single  security  bug   •  While  moving  fast   •  With  minimal  impact  to   developers   •  Within  an  agile  or  constant   deployment  model   •  Across  thousands  of   developers,  mulJple  sites   and  services,  and  numerous   new  lines  of  code   Ensuring  no  criQcal  bugs  are   introduced  to  so]ware   Hard   Easy   (generally)  
30. QuesJon  the  Models   •  Industry  Drivers   – PCI,  Sarbanes  Oxley,  Hipaa,  Self  RegulaJon   •  Business  Drivers   – InnovaJon,  fail  fast,  Jme  to  market,  compeJJve   disadvantage     •  Development  PracJces   – Code  Reuse,  Libraries,  Patching  
31. Standards  Based  Security  is  Failing   •  MoJvates  for  compliance  over  security   •  Complex  &  unrealisJc  in  many  scenarios   •  RetroacJve  removal  of  cerJficaJon  
32. Business  MoJvaJon   •  Security  someJmes  viewed  as  tax   •  Tradeoff  of  Jme  to  market   •  Put  off  by  aggressive  security  requirements   – An  overly  secure  system  used  by  no  one  provides   no  security  
33. ORGANIZING  FOR  SECURITY   Company  Structure  is  CriJcal  
34. Humans  Don’t  Scale  Well  
35. Humans  Don’t  Scale  Well  
36. Hiring  More  Security  Isn’t  RealisJc   Security  Professionals   – Expensive   – Hard  to  find   – CompeJJon  for  employment  
37. Centralized  Security  OrganizaJon   •  Accountability  &  leadership   •  Increases  communicaJon   •  Enables  security  vision  &   forward  planning   •  Cohesive  vision  across   security  disciplines   ApplicaJon   Security   Network  Ops   Security   Corporate   Security   InformaJon   Security  
38. Centralized  Security  OrganizaJon   •  Build  bridges  throughout  company   •  Become  partners  with  groups   •  Increase  communicaJon  &  support   Dev   QA   Product   PR   IT   Legal   Security  
39. Influence  instead  of  Dictate   •  Teach  security   approaches   throughout  org   •  Build  tools  &  guidance   •  Avoid  processes  that   require  security  staff   involvement   Avoid  security  choke  point   Influence  without  blocking  
40. Embedding  Approach   •  Embedding  security   inside  dev  team   – team  effort  to  deliver   product   – real  Jme   collaboraJon   – eliminates  “us”  vs   “them”   – build  alliance   Developer   Team   Developer   Team   Developer   Team   Security  Team  
41. OrganizaJonal  Strategy   •  Scaling  via  Security  Champions   •  Primary  Role:  Developer,  Secondary:  Security     •  Scales  EffecJvely   •  Liaison  to  security  team   Developer  Team   Security  Champion   Developer  Team  
42. Security  Throughout  SDLC  
43. Development   •  Developer  Training   •  Coding  Guidelines   – Cheat  Sheets   – Concise,  Usable   owasp.org/index.php/Cheat_Sheets  
44. Development   •  Security  Libraries  &  Services   – Abstract  away  internals  of  security  code   – Standardized  security  libraries   •  OWASP  ESAPI  –  an  example  of  what  you  should  build   within  your  organizaJon   •  Engineered  web  services  for  security  
45. Safety  Proof  &  Shi6  Burden   Current   •  Developer  must  remember   to  enable  security   •  Ability  to  build  anything  –   for  beXer  or  worse   Necessary   •  Security  fully  enabled,  opt-­‐ out  of  security  with  cauJon   •  Pre-­‐packaged  code  widgets   –  Appeal  to  masses   –  Limited  customizaJon   –  Safe  for  beginners  
46. Smart  AutomaJon   •  Dynamic  security   analysis  built  for   developers   –  Report  what  can  be   found  >95%  accuracy   –  Skip  issues  where   accuracy  is  low   –  Accurate  Tool  >  Tool   which  requires   security  team   wiki.mozilla.org/Security/Projects/Minion  
47. AutomaJon   StaQc  /  Dynamic  Analysis     Can  scale  if  homogenous  environment   Careful  of  human  involvement     Security  X  as  a  Service   Yes!  The  Future!  
48. Quality  Assurance   •  Security  validaJon  within  QA   •  FuncJonal  tesJng  of  forms  +  basic  sec  tests   •  Follow  paXerns  of  current  QA   – Pass  /  Fail   – Self  contained  tesJng  –  no  need  for  security   evaluaJon   “><script>alert(‘problem’)</script>  
49. Post  Release  -­‐  Bounty  Programs!   Engage  Security  Community  
50. Post  Release  –  Defend  The  App   •  Detect  and  repel  common   aXacks     –  Web  ApplicaJon  Firewall   •  Detect  and  repel  custom   aXacks  at  business  layer     –  Integrated  applicaJon  defense   –  OWASP  AppSensor     •  Disable  ability  for  automated   aXacks   owasp.org/index.php/OWASP_AppSensor_Project  
51. Post  Release  –  Defend  at  Scale   •  Design  for  Scale   – Automated  aXack   blocking  &  deflecJon   – No  human  analysis  in   criJcal  path.   •  Human  interacJon     – Slow     – IneffecJve  against   distributed  aXacks  
52. Key  Points   Adversary  is  moJvated  and  talented   – Organized  criminal  aXackers   – Resourced  and  focused  
53. Key  Points   SaJsfying  security  standards  is  a  false  sense  of   security   – Focus  on  acJviJes  brining  value   – Meet  required  standards  &  understand  lack  of   value  
54. Key  Points   Complex  systems  require  comprehensive   security   – Integrate  security  in  every  step  of  so6ware   development   – Build  to  scale  with  business  needs  &  development   speed
