These are soceket based security callbacks. If they do not exist in the SecurityPlugin or if the SecurityPlugin does not exist they they are not used.

These security plugin calls then call the platform api calls

secDisableSocketAccess		calls ioDisableSocketAccess		-> allowSocketAccess : 0, return 1
secHasSocketAccess			calls ioHasSocketAccess		-> return allowSocketAccess
secCanConnectToPort			calls ioCanConnectToPort		-> return allowSocketAccess
secCanListenOnPort			calls ioCanListenOnPort			-> return allowSocketAccess
secCanCreateSocketOfType		calls ioCanCreateSocketOfType	-> return allowSocketAccess

Socket access is on by default, if turned off, then it's off. There is no fine grained logic,like allow listen, but not connect. It's either on for all or off.
