WIFI: ITS ABOUT THE DATA …

WHAT WAS THE PROBLEM ?

NO, REALLY … NS slide

MYWIFIEXPERIENCE journey “WiFi OK?” “Net-IDs not working!!” Vendor tools? Data? Solution must be fast! Development: “Own Dog Food” Crowd source “Visual?” Big Data How hard can it be …

THINK ABOUT THE ISSUES Logs: 1000 per minute (x2) Speed (Data; Monitoring Data) DB speed Device type Aruba: “general device type” Responsive design Privacy issues (helpdesk) (Mem)Cache Customer: “you/us”

SECURITY BY DESIGN SDLC (security development life cycle) “Spiral (waterfall; go back)” project management Privacy assessment Language security checklist Web server security checklist

TOP 6 RISKS 1.Big Data: mitigate 2.(Data) Speed: eliminate 3.DB: mitigate 4.Device type: mitigate 5.Cache: mitigate 6.Privacy: mitigate

UNKNOWN UNKNOWNS? Logs: 1000 per minute (x2) -> VERY HARD Speed (Data; Monitoring Data) -> VERY HARD DB speed -> NO DB IPV6 -> 2,417,851,639,229,258,349,412,352 x 4 Device type -> VERY HARD

OK? SO?  All initial goals met; live for 8+ months  Aruba (now HP) became interested  Aruba API calls  Aruba general monitoring improvement  Aruba adding a caching layer  Open source my code; not vendor specific  “working” to open API  OAUTH2 for user apps  “Virtual” WiFi helpdesk
