Description: There is a loss of connectivity between processes.

ServiceChannel

Represents a communication path through the network between a Client and a Service. This channel is privileged, in the sense that where default firewall rules would block connections from the Client to the Service, they are enabled by an exception to the default rules.

HostChannel

Represents a physical network path between physical hosts that is used to route traffic in a virtual subnet, underpinning a Virtual Channel.

VirtualChannel

Link between two physical hosts that is needed to support communication between clients and services over virtual networks.

LossOfConnectivity
SC.A.CCCmSCS.0

Client Client cannot access unavailable service Service: loss of availability in the service Service makes the connection from Client unavailable on all channels.

SC.A.CCfImSC.0

Connection from CHost to LogicalSubnet affects communication between Client and Service: if the connection of device CHost running Client and subnet LogicalSubnet is not available, this will affect the communication channel between client Client and service Service.
LossOfConnectivity
SC.A.CCtImSC.0

Connection from SHost to LogicalSubnet affects communication between Client and Service: if the connection of device SHost running Service and subnet LogicalSubnet is not available, this will affect the ccommunication hannel between client Client and service Service.
LossOfConnectivity
SC.A.HuSC.6.3

Suspended insecure path from Client to Service affects availability: firewall rules allowing access by Client to service Service via a network path may be suspended where communication on that path is exposed to snooping. However, this means the availability of Client-Service connections using this network path will be reduced if its communication security is under threat.
LossOfConnectivity
SC.A.LSmSC.0

Unavailable subnet LogicalSubnet affects client-service communication: if subnet LogicalSubnet is not available, it will interrupt client-service communications via that subnet.
LossOfConnectivity
SC.A.SC.6.1

Disabled channel from Client to Service is not available: if the firewall rules allowing access by client Client to service Service have been disabled, then Client will not be able to access Service via that channel.
LossOfConnectivity
SC.A.SgmSC.0

Unavailable route at gateway Gateway affects client-service communication: if the route via Gateway from FromSubnet to ToSubnet is not available, it will interrupt client-service communications that depends on this route.
LossOfConnectivity
SC.A.VC2HmSC.0

Loss of physical connectivity between LocalHost and RemoteHost affects client-service communications: if there is a loss of availability in physical network paths between LocalHost and RemoteHost supporting communications in subnet VirtualSubnet, then client-service communication via that virtual subnet will become unavailable.
LossOfConnectivity
SC.A.HuCAPmSC.6.2

Suspended channels from Client to vulnerable service Service via LogicalSubnet are not available: the firewall rules allowing access by client Client to service Service may be disabled if the risk of an expoit by an attacker on subnet LogicalSubnet is too high. . However, this cuts privileged network paths, so communication between Client and Service via that subnet will become unavailable.
LossOfConnectivity
SC.A.HuSAPmSC.6.2

Suspended channels to vulnerable service Service via LogicalSubnet cuts availability: the firewall rules allowing access to service Service via LogicalSubnet may be suspended if necessary to prevent attacks. However, this cuts privileged network paths, so communication with Service via that subnet will become unavailable.
