VULNERABILITIES
“724,000 taxpayers victims of the
latest data
breach … with automated, brute
force probe using IRS's public
API ...”
–Forbes
“... individuals obtained access to
high-profile Instagram users'... by
exploiting a bug in an Instagram
API”
–Instagramstatement

SO HOW DO WE PROTECT THE
CONSUMERS/EMPLOYEES DATA?

STANDARDS CAN
MULTIPLY THE IMPACT
OF APIS
o More extensible
o More interoperable
o More secure

ACCESS SECURITY AUTHORITY
Ensure the right people have access to the right resources
Secure access at the app, API, and page/URL
level
 Protect resources on-prem and in the cloud
 Enforce policies via proxy and/or agent models
 Replace or coexist with legacy WAM
 Single logout and session control
Adaptive access policies based on user,
device, resource, context and more
 Centrally manage policies across hybrid IT
 Continuous authentication
Deploy on-prem or in your cloud
 Automated deployment & auto-scaling in AWS

THE KEY REQUIRED (& FUTURE)
STANDARDS

IDENTITY STACK

OAUTH2.0
MINIMUM MANDATORY !
 IETF RFC 6749 – 6750
– OAuth2.0 Specs
– Authorization Framework
– RFC 8252: OAuth 2.0 for Native Apps
 IETF RFC 7636
– Proof Key for Code Exchange by OAuth Public Clients
– PKCE, pronounced "pixy”

OAUTH2.0
To monitor its implementation
 OAuth 2.0 Token Binding
– Token Binding: Cookie, Access Tokens, Authorization Codes,
Refresh Tokens, JWT Authorization Grants, and JWT Client
Authentication
– Token Binding (TB) protocol is IETF RFC (Oct.2018): RFC
8471/2/3

FOR IOT DEVELOPERS
Coming soon

WHAT IF THE TOKEN IS STOLEN?

WHAT’S WRONG WITH OAUTH2 ACCESS
TOKEN?
Bearer Token
{
"sub":"jsmith@anycompany.org",
"uid":"jsmith@anycompany.org",
"active":true,
"iddwJson":"n/a",
"token_type":"Bearer",
"exp":1544224231,
"client_id":"ac_client",
"email":"jsmith@anycompany.org",
"username":jsmith@anycompany.org
}
1. Tokens can be revoked
o As specified in the specs,
2. New Token Binding
specs
3. But… when token or
credentials are stolen?

Security Beyond Access Control
Security Beyond WAF
ADDRESSING API SECURITY GAP
 Extending Foundational API security
to protect against cyberattacks on APIs
 Security needs beyond existing security:
• Login/Identity attacks detection
• API-specific DoS/DDoS attacks protection
• Detecting Cyberattacks on data, apps,
systems
 Need full API activity reporting at scale
API SECURITY TODAY
Access Control and WAF
Tokens,Authentication/Authorization/AttackSignatures
Rate Limiting
Clientthrottling,quotas
Network Privacy
SSL/TLS
THE MISSING PIECES
Data, Application, System Attacks
APTs, DataExfiltration,Deletion…etc.
API DoS/DDoS Targeted Attacks
Compromised API Services Access
Login/OAuth/Authentication Attacks
Credential Stuffing,Fuzzing,Stolen Cookies andTokens

DO YOU HAVE VISIBILITY INTO API
TRAFFIC?
Do you know Who’s/What’s connected to
your APIs at all times?
API activity needs tracking & reporting
 APIs accessed by Who / What / When
 Command/method activity on each API
 Timeline
 Anomalous Behavior
Dumping logs for tracking does not work
– BIG DATA PROBLEM –
APIs
/login
/query
/update
/account
/order
WHAT IS HAPPENING
WITH YOUR APIS?
