A method is provided in one example embodiment that includes receiving metadata from a host over a metadata channel. The metadata may be correlated with a network flow and a network policy may be applied to the connection. In other embodiments, a network flow may be received from a host without metadata associated with the flow, and a discovery redirect may be sent to the host. Metadata may then be received and correlated with the flow to identify a network policy action to apply to the flow.

System and method for redirected firewall discovery in a network environment

A method in an example embodiment includes correlating a first set of event data from a private network and determining a local reputation score of a host in the private network based on correlating the first set of event data. The method further includes providing the local reputation score of the host to a security node, which applies a policy, based on the local reputation score of the host, to a network communication associated with the host. In specific embodiments, the local reputation score of the host is mapped to a network address of the host. In further embodiments, the first set of event data includes one or more event indicators representing one or more events, respectively, in the private network. In more specific embodiments, the method includes determining a local reputation score of a user and providing the local reputation score of the user to the security node.

System and method for determining and using local reputations of users and hosts to protect information in a network environment

A proxy device such as a firewall uses an internal socket namespace such as a text string such that connection requests must be explicitly redirected to a listening socket in the alternate namespace in order to connect to a service. Because external connections cannot directly address the listening socket or service, greater security is provided than with traditional firewall or proxy devices. To receive a redirected proxy connection, a service process creates a listening socket and binds a name in an alternate namespace to the socket before listening for connections.

Named sockets in a firewall

A method is provided in one example embodiment that includes intercepting a network flow to a destination node having a network address and sending a discovery query based on a discovery action associated with the network address in a firewall cache. A discovery result may be received and metadata associated with the flow may be sent to a firewall before releasing the network flow. In other embodiments, a discovery query may be received from a source node and a discovery result sent to the source node, wherein the discovery result identifies a firewall for managing a route to a destination node. Metadata may be received from the source node over a metadata channel. A network flow from the source node to the destination node may be intercepted, and the metadata may be correlated with the network flow to apply a network policy to the network flow.

A computer network device comprises an intrusion prevention rule set comprising a plurality of rules, each of the plurality of rules associated with two or more rule classification parameters, and an intrusion prevention module that is operable to use two or more of the classification parameters associated with the plurality of intrusion protection rules to selectively apply the rules to provide network intrusion protection of network traffic.

Unified network threat management with rule classification

A secure commerce server system and method. A secure commerce server system includes a plurality of regions or burbs, including an internal burb and an external burb, a commerce server and an administration server. Processes and data objects associated with the administration server are bound to the internal burb. Processes and data objects associated with the commerce server are bound to the external burb. Processes bound to one burb cannot communicate directly to processes and data objects bound to other burbs. The administration server cannot be manipulated by a process bound to the external burb.

Secure server utilizing separate protocol stacks

A proxy which is part of a firewall program controls exchanges of information between two application entities. The proxy interrogates attempts to establish a communication session by requesting entities with a server entity in lower layers in accordance with defined authentication procedures. The proxy interfaces with networking software to direct a communication stack to monitor connection requests to any address on specific ports. The requestor's address, and the server's address are checked against an access control list. If either address is invalid, the proxy closes the connection. If both are valid, a new connection is setup such that both the requestor and server are transparently connected to the proxy with variable higher levels being connected in a relay mode. Protocol data units are interrogated for conformance to a protocol session, and optionally further decoded to add additional application specific filtering. In one embodiment, an OSI architecture comprises the levels.
