Sentriant NG Operation Console User Guide, Software Version 2.5
A local system on the network is contacting a large number of remote
hosts. This could signal the presence of a virus or worm.
Too many used (i.e., real) IP Addresses have been contacted by a
single host. A used address is an address that has a real machine
associated with it.
The Sentriant NG has detected a source attempting to contact too
many unused IP Addresses.
A time scale that is the basis for the worldwide system of civil time.
Referred to as Coordinated Universal Time (abbreviated UTC), this time
scale is maintained by highly precise atomic clocks located around the
world. UTC is accurate to a nanosecond per day.
A host or workstation using an IP Address within the protected range
of a Sentriant NG. It responds to Address Resolution Protocol (ARP)
requests and sends traffic on the network.
Virtual Local Area Network - A logical, or administratively configured,
LAN or broadcast domain that is defined by software rather than by
fixed, physical port connections.

within) the protected range(s) of the Sentriant NG.
