One method of attempting to gain access to a resticted area of the network is to insert a bogus source address in the packet header to make the packet appear to come from a trusted source. This technique is called IP spoofing.
ScreenOS has two IP spoofing detection methods, both of which accomplish the same task:
determining that the packet came from a location other than that indicated in its header. The method that a Juniper Networks secrutiy device uses depends on whetehr it is operating at Layer 3 or Layer 2 in the OSI Model.
