SonicOS/X API Reference Guide

Pros and Cons of the Different Schemes

Each of the four authentication schemes supported by SonicOS 6.5.4 API has pros and cons, and not all of them are usable in all situations.

Generally, the recommendation is to use Public Key Authentication if administrative user accounts are used that need to be authenticated remotely via RADIUS, LDAP or TACACS+, and use HTTP Digest Authentication otherwise.

Refer to the overview table below for a comparison:

Situations HTTP Basic HTTP Digest Public Key CHAP
Level of security: Low Very High High Medium
Supported in 3rd party utilities (curl, etc.): Yes Yes No No
Client complexity: Low Low Medium-High Medium
Remote authentication: Compatible with all Not possible Compatible with all RADIUS only
Efficiency/performance: High Medium Low Medium
