What are the three authentication methods for SIC?

A.

B.

Explanation:
Secure Internal Communication (SIC)
Secure Internal Communication (SIC) lets Check Point platforms and products authenticate with each other.
The SIC procedure creates a trusted status between gateways, management servers and other Check Point
components. SIC is required to install polices on gateways and to send logs between gateways and
management servers.
These security measures make sure of the safety of SIC:
Certificates for authentication
Standards-based SSL for the creation of the secure channel
3DES for encryption
