sufficient configuration of security parameters, but the details are expected

### Allowed security protocols

Name:
: allowedSecurityProtocols

Type:
: Implementation-specific enumeration of security protocol names and/or versions.

Default:
: Implementation-specific best available security protocols

This property allows applications to restrict which security protocols and security protocol versions can be used in the protocol stack. Applications MUST be able to constrain the security protocols used by this or an equivalent mechanism, in order to prevent the use of security protocols with unknown or weak security properties.
