Embodiments relate to systems and methods for extending a network security platform to a cloud-based network. A set of managed machines, such as personal computers or servers, can be managed by a network security engine. The network security engine can govern access to and operation of the set of managed machines through a set of security policies. According to embodiments, the set of security policies can be sub-divided into a partitioned security class corresponding to a subset of the managed network which is intended to be deployed as a cloud-accessible subset of the overall managed network. The partitioned security class can specify access restrictions for the cloud-accessible subset to receive resources from or provide resources to the external cloud environment. A corporate campus network or other managed network can therefore permit access of the cloud to some or all of its machines, while still maintaining desired local security conditions.

A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the “operational context” for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the “least-cost path” to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP “Trace” messages facilitate network diagnostic tools. Ethernet or UDP / IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.
