31 | 2 | Anonymous | |
32 | 2 | Anonymous | The System class describes a system or network involved in an event. The systems or networks represented by this class are categorized according to the role they played in the incident through the category attribute. The value of this category attribute dictates the semantics of the aggregated classes in the System class. If the category attribute has a value of "source", then the aggregated classes denote the machine and service from which the activity is originating. With a category attribute value of "target" or "intermediary", then the machine or service is the one targeted in the activity. A value of "sensor" dictates that this System was part of an instrumentation to monitor the network. |

205 | 2 | Anonymous | |
206 | 2 | Anonymous | The Service class describes a network service of a host or network. The service is identified by specific port or list of ports, along with the application listening on that port. |
207 | 2 | Anonymous | When Service occurs as an aggregate class of a System that is a source, then this service is the one from which activity of interest is originating. Conversely, when Service occurs as an aggregate class of a System that is a target, then that service is the one to which activity of interest is directed. |

237 | 2 | Anonymous | Either a Port or Portlist class MUST be specified for a given instance of a Service class. |
238 | 2 | Anonymous | |
239 | 2 | Anonymous | For a given source, System@type="source", a corresponding target, System@type="target", maybe defined, or vice versa. When a Portlist class is defined in the Service class of both the source and target in a given instance of the Flow class, there MUST be symmetry in the enumeration of the ports. Thus, if n-ports are listed for a source, n-ports should be listed for the target. Likewise, the ports should be listed in an identical sequence such that the n-th port in the source corresponds to the n-th port of the target. This symmetry in listing and sequencing of ports applies whether there are 1-to-1, 1-to-many, or many-to-many sources-to-targets. In the 1-to-many or many-to-many, the exact order in which the System classes are enumerated in the Flow class is significant. |
