Pairing Key for Cisco WSA and Cisco ScanCenter for CTA

A.

The correct answer is A, a public SSH key that the Cisco WSA generates.

CTA ( Cisco Threat Awareness Service) is a cloud-based service provided by Cisco that allows organizations to monitor and analyze web traffic for potential security threats. The Cisco Web Security Appliance (WSA) and Cisco ScanCenter are two components of the CTA solution.

To pair the Cisco WSA and Cisco ScanCenter for CTA, the Cisco WSA generates a public SSH key that is used to establish a secure communication channel between the two components. This key is then provided to the Cisco ScanCenter, which uses it to authenticate and encrypt all communication with the Cisco WSA.

Option B, a public SSH key that Cisco ScanCenter generates, is incorrect because the Cisco WSA needs to generate the key to establish the secure communication channel.

Option C, a private SSH key that Cisco ScanCenter generates, is incorrect because private keys are used for authentication, not encryption, and it is the public key that needs to be shared.

Option D, a private SSH key that the Cisco WSA generates, is incorrect because private keys are not shared and are only used for authentication purposes. In addition, it is the public key that is required to establish a secure communication channel between the Cisco WSA and Cisco ScanCenter.
