Methods, apparatuses and systems enabling a distributed wireless network
security system. In one embodiment, the present invention provides a
wireless network system where security policies are automatically
distributed and uniformly implemented across wireless network access
points. Embodiments of the present invention address the situation where
a malicious user moves to a different access point within a wireless
network environment after failing to properly authenticate and/or
associate at a first access point. Embodiments of the present invention
enable an integrated, multi-layer network security system, wherein a
security mechanism at one layer (e.g., link layer security mechanisms)
can set policies based on information gleaned from operation of a
security mechanism at another layer (e.g., application layer
authentication servers).
