1 SIGS Afterwork Event in Geneva API Security as Part of Digital Transformation Projects The role of API security in digital transformation Nagib Aouini, Head of Cyber Security Services Defense & Cyber Security Genève, Hôtel Warwick, En partenariat avec CA Technologies

2 AGENDA Transforming your business in the digital era API Security challenges 15 min Best practices 5 min API security for digital transformation - SIGS 2

3 DIGITAL TRANSFORMATION IS THEIR KEY TO SURVIVAL API security for digital transformation - SIGS 3

4 SMOKE SIGNALS FOR DIGITAL TRANSFORMATION building apps for our new cloud platform... a mandate to double mobile revenue a big UX/CX initiative in the works need to improve the customer experience massive CMS and commerce re-platform speed up our market responsiveness catch up with X and future-proof our business shift customers to the secure digital solution hacked our connected product API security for digital transformation - SIGS 4

5 APIS: THE BUILDING BLOCKS OF DIGITAL TRANSFORMATION Cloud External Developers Mobile Data Data Your Digital Business Partners/External Divisions IOT Devices APIs API security for digital transformation - SIGS 5

that allow software applications to share data and

6 WHAT ARE APIS Your App REQUEST API Their App DATA Application Programming Interfaces (APIs) are plugs that allow software applications to share data and functionality. API security for digital transformation - SIGS 6

7 API 101 PRIMER AFTER "alerts": [{ type": FLW "description": Flood Watch" Integration Experience Speed Monetization Internet of Things API security for digital transformation - SIGS 7

8 WHY MODERNIZE? WHY USE APIS? APIs have become the industry standard for system interfaces of all kinds. Hide complexity; expose existing functionality Use APIs as the basis for porting systems/functionality into the cloud Make it easier for other business units and business partners to access systems and data, but maintain security Next step in evolution of SOA/Integration platforms Want to have benefits of APIs API security for digital transformation - SIGS 8

9 BUSINESS CHALLENGES Project Business Team : How can I make my business data available through a mobile app? Do I need to copy my data to a mobile phone? IT Security Officer I know that consuming data from a mobile app contains some risk. How to reduce risk while expanding API exposure? How to meet compliance? Developer What options I have to secure data in rest and transit? How can I securely manage keys? How to manage authentication within the app? Operations IT Team How do I enforce consistent security policy across APIs? What controls I have to mitigate attacks like DoS on our back-end? Privacy Officer How do I govern APIs exposed to internal and external developers (third-party or agency)? How do I manage the PII life cycle of data exposed via APIs API security for digital transformation - SIGS 9

10 AGENDA Transforming your business in the digital era API Security challenges 15 min Best practices 5 min API security for digital transformation - SIGS 10

11 API BREACHES API security for digital transformation - SIGS 11

12 API SECURITY IS UNIQUE Your APIs are vulnerable to the typical OWASP Top 10 attacks IN ADDITION, you have to worry about: Hackers reverse engineering apps to access private APIs API key theft looks like legit usage! Traffic spike protection by way of bots or DoS attacks Identity tracking across API sessions XML/JSON injection-type attacks Token harvesting due to insecure communication or storage API security for digital transformation - SIGS 12

13 SECURE WHAT? Mobile Device Management API Management Protect data at-rest Protect data source / data in-motion Mobile browser Web Any other app APIs API security for digital transformation - SIGS 13

{ "type" : office", "number": 0216132136" }, { "type" : home", "number":

14 FOR EXAMPLE: { "firstname": John ", "lastname" : Williams", title" : VP of engineering, "address" : { "streetaddress": 21 Avenue de la Harpe", "city" : Lausanne", prov" : VD", "postalcode" : 1001" }, "phonenumber": [ { "type" : office", "number": " }, { "type" : home", "number": xxxxxxx" } ] } Without proper authentication/authorization, a corporate directory can be leaked over the internet!

15 SECURING YOUR DIGITAL CHANNELS Authenticate the user Control what the App can access Rate Limit access Protect from hackers PCI compliance Quota Management Protection Licensing Au/Az/SSO API security for digital transformation - SIGS 15

16 DEFENSE IN DEPTH : SECURE YOUR APIS Users Apps APIs Backend OAuth2 MFA Federated login API key OAuth2 TLS IP access control Spike arrest Rate limits Threat protection Intrusion detection DDoS Mutual TLS IP access control API security for digital transformation - SIGS 16
