Improve System Security and Reliability Part 2

The layered and interdependent SoftEcoSDK mechanisms include:

An infrastructure mechanism monitors and controls program activation. A program starts up by obtaining configuration, connecting to the infrastructure, and becoming a standby instance. The infrastructure monitors program status to detect the absence of an active instance, choose a standby instance, and direct it to become active.

An infrastructure mechanism provides secure and reliable message publishing to subscribers. A message passes through a main hub computer where a white list is applied to ensure that only authorized computers are senders and receivers per message type. There is only one active publisher program per message type so that a subscriber can detect a missed message. A message travels two paths to bypass delays or failures in one of the paths

An infrastructure mechanism provides a secure and reliable message connection between a child program and an active parent program. A program instance can also connect to an active instance of the same program. A message connection passes through a main hub computer where a white list is applied to ensure that communication only happens between related programs. No white list is applied for messages communicated on a connection between related programs. A connection between unrelated programs is not allowed as this is an unsafe practice that leads to a security breach. A message travels two paths to bypass delays or failures in one of the paths. A connection is terminated when a missed message is detected.
