5. Strong Authentication in the Banking Environment

6. 6 Challenges and Goals  Reduce cost by moving business processes online  By Increasing use of online banking  By Moving other applications online  Address phishing attacks to restore/increase consumer confidence in online banking  Enhance customer relationships, win new customers and add new products and applications  Be compliant with regulation and mitigate risk  E.g. FFIEC in the US  Provide a viable solution from a TCO point of view  Provide a solution for both employees and customers

7. 7 The Consumer Reality  Customers are heterogeneous set of individuals  Varying level of expertise with computers and technology  Use Multiplicity of devices for access  Home PC, office PC, Internet café etc.  Variety of tasks are performed  Equally likely to embrace new solutions or move to alternate channels No one solution is going to make everybody happy; flexible solution suites provide multiple options

8. 8 FI as an extended enterprise  More systems open and accessible to non-employees  Technology creates increased reach and flexibility  FIs no longer limited by geography or timing  Increased benefits and potentially increased risks Employee Consumer Client Partner

9. 9 Risk Management in Financial Institutions  FIs trying to maintain a balance between security and user convenience…  On the one hand  Need to reduce risk  Need to provide assurance to consumers (or they might switch to ‘less risky’ but potentially more expensive channels)  On the other hand  Need to make experience simple; and not drive away consumers  Need to contain costs of solution – proportionate to perceived risk

10. 10 Threats facing the industry  Phishing  Spurious message (likely, email) that induces user to enter critical personal information at a bogus site  Many variations exist, but email is easiest and cheapest for the fraudster  Pharming  Modifying DNS entries to redirect user to bogus site  Malware  Programs planted in user’s desktop to capture key-strokes, mouse clicks  Man-in-the-middle  User redirected to intermediate site that behaves like genuine site to the user and in turn behaves like user to the genuine site

11. 11 Solution Categories  Server Authentication  Identifying server to the User  Assurance that user is at the right site, or that user received mail from right source  Base User Authentication  Determine that user is likely to be who he/she claims to be  Based on device used by user, location of user, habits of user…  For example, activating a card by calling from home telephone number  Typically achieved without user active participation  Strong (Unique User) Authentication  Determine with high level of assurance that the user is who he/she claims to be  Based on credential issued to the individual – combination of something he/she is, something he/she has, something he/she knows  User explicitly participates in the process

12. 12 Considerations  Usability  Consumer Ease of Use  Distribution, Training, Renewal, Help-Desk  Deployment  Standards based – vendor dependence  Disruption to existing applications  Software required at consumer desktop?  Protection against  Phishing  Pharming  Trojans, Spyware  Man-in-the-middle attacks  Additional features  Strong Authentication  Obsolescence Proof  ROI enhancement  What does it cost

13. 13 Server Authentication  SSL Lock – yellow lock at bottom of page  Best possible technology solution  Not vulnerable to man-in-the-middle attacks  Provides complete assurance that user is at the right site  However two big limitations  Browser technologies allow this to be spoofed – not all users will know how to detect the spoof  FI are not standardized on which pages are SSL locked (often password entry page is not locked; only password submission triggers this)  Alternate/Addition is to provide an ‘assurance message’  Enter userid, wait for server to display ‘shared secret’, then enter password.  Shared secret can be text or other information the user is likely to recognise

14. 14 Assurance Message  Protects against phishing and pharming  Provides a first level assurance (authenticate server to user)  Widely deployed mechanism as part of 3-D Secure  (Visa and MasterCard)  Fingerprinting of “registered” computers  Browser based - no client side software required  Easy to use; simple to train end users  Complements any form of user authentication Enter User Name Display Assurance Message Verification Dialog Enter Password Registered computer Unknown computer

15. 15 Assurance Message Example

16. 16 Limitations of Assurance Message  Does not authenticate user to server  Vulnerable to man-in-the-middle (MIM) attacks  User conditioned to accept verification dialog  Does not know why ‘fingerprinting’ failed  Depends on ‘velocity checks’ for MIM IP addresses @ Real Bank Site Man-in-the-middle Attacker 1. User-id 2. User-id 3. Verification Dialog 4. Verification Dialog

17. 17 Base User Authentication  Circumstantial forensics, in addition to userid / password  Combination of elements  Machine fingerprint (including cookies left there)  Location of IP address that transaction is originating  Evaluate elements => determine if transaction is risky  Action to be taken next is variable  Flag to alert user  Ask for secondary authentication (maybe different credential)  Switch to second factor (email, call, SMS)  Route through different process – CSR interrupt  Deny transaction

18. 18 Limitation of User ‘Approximation’  No protection against ‘friendly’ fraud  People in same household or even at workplace  Share machines, share IP address, share ‘location’  Risk scoring – inexact science  False positives – user inconvenience  Need number of transactions even to ‘learn’ pattern – several applications (including e-Banking) don’t lend themselves to such volume  Action on risk detection  SMS, Callback – not reliable for online activity  Second authentication – again conditions user to expect this question – potential for phishing

19. 19 Strong (Unique User) Authentication  Issue strong credential to individual user  User is told about strong credential  User knows sharing credential opens him/her for risk  Ask for strong authentication  For all access  For access to specific ‘high risk’ areas  For ‘high risk’ transactions only (based on amount, type etc)  Typical strong authentication is 2-factor  Two of three things - something you have, something you know or something you are (biometrics)

20. 20 Challenges to Strong Authentication  Cost  Issuing new credentials  Training users  Inconvenience  Learning to use 2 factors  Access when one factor is missing – user travels without something he/she has  Application upgrade  Applications need to know how to use this technology and authenticate users – new systems, new integration

21. 21 Electronic Business Enablement View  Beyond Compliance and Risk Mitigation  Authentication strategy must  Maintain simplicity  Provide IT and business process flexibility  Facilitate retention and acquisition of customers  Allow new products/services to be delivered  Strengthening Customer Relationship and adding new applications

22. Arcot’s Layered Authentication Approach

23. 23 Digital Signing (En)/Decryption (ArcotID + certificates) Layered Authentication Approach Increasing Value and Benefits – Security + Other Uses (Signing/Encryption) UserID / Password Arcot Level 1 Solution Arcot Level 2 Solution Arcot Level 3 Solution Mutual Authentication / Assurance Message + Srambled PIN Pad Device ID Location ID Geo Location Crypto Strong Authentication (ArcotID)

24. 24 Layered Authentication Approach  Without user intervention  Usage of machine and connection characteristics to determine whether user is genuine, e.g.  IP address  Browser version  Comparison with last good access, or information at registration time  With user intervention  Strong Authentication using ArcotID  Additional Security Features  Personal Assurance message  Scrambled PIN pad

25. 25 Customizable Authentication Approach Scrambled PIN Pad – defeats Keyboard loggers “Assurance Message” – for Site Authentication ArcotID for Strong Authentication IP and Device Forensics – for Increased Identity assurance

26. 26 The ArcotID Enabled Application Username Password ArcotID Software Smart Card The power of two-factor, with the simplicity of passwords …

27. 27 Fully Flexible Solution Multiple levels of functionality available  Authentication Only  No installed software required  Java/Flash on-demand  Add Digital Signing, Encryption  Requires client software for advanced functionality  Staged approach possible  addressing current business requirements  and providing a future-proof solution using the same framework  Provide the user with a security solution that addresses the risk and is still user-friendly
