You are integrating Cisco SecureX with a third-party SIEM. When configuring a webhook for event notifications, which authentication method is natively supported by the SecureX webhook integration for secure delivery?
Trap 1: OAuth 2.0 Client Credentials flow
OAuth is used for API access, not for verifying outbound webhook integrity.
Trap 2: Mutual TLS (mTLS) certificate exchange
While secure, mTLS is not the primary configuration method for simple webhook notification endpoints.
Trap 3: Basic Authentication with fixed credentials
Basic authentication is not the recommended or natively supported method for SecureX webhooks.
- A
OAuth 2.0 Client Credentials flow
Why it fails: OAuth is used for API access, not for verifying outbound webhook integrity.
- B
HMAC-SHA256 signature verification
SecureX uses HMAC-SHA256 signatures to verify that the payload was sent by the trusted source.
- C
Mutual TLS (mTLS) certificate exchange
Why it fails: While secure, mTLS is not the primary configuration method for simple webhook notification endpoints.
- D
Basic Authentication with fixed credentials
Why it fails: Basic authentication is not the recommended or natively supported method for SecureX webhooks.
