Abstract

According to one exemplary embodiment, a method for load balancing between a virtual component within a virtual environment and a Host Intrusion Prevention System (HIPS) is provided. The method may include receiving a trusted connection table from the HIPS, wherein the trusted connection table contains a plurality of trusted connection information. The method may also include receiving a network packet from a virtual switch, wherein the network packet has a plurality of connection information. The method may then include determining if the plurality of connection information matches the plurality of trusted connection information. The method may further include sending the network packet to a destination based on determining that the plurality of connection information matches the plurality of trusted connection information. The method may include sending the network packet to the HIPS based on determining that the plurality of connection information does not match the plurality of trusted connection information.

Claims

1. A method for load balancing between a virtual component within a virtual environment and a Host Intrusion Prevention System (HIPS), the method comprising:

receiving a trusted connection table from the HIPS, wherein the trusted connection table contains a plurality of trusted connection information;

receiving a network packet from a virtual switch, wherein the network packet has a plurality of connection information;

determining if the plurality of connection information matches the plurality of trusted connection information;

sending the network packet to a destination based on determining that the plurality of connection information matches the plurality of trusted connection information; and

sending the network packet to the HIPS based on determining that the plurality of connection information does not match the plurality of trusted connection information.

2. The method of claim 1, wherein the virtual environment comprises a virtual input output server (VIOS), a hypervisor and a plurality of virtual Ethernet adapters.

3. The method of claim 2, wherein the virtual component is a trusted firewall running within the VIOS or the trusted firewall running within the hypervisor.

4. The method of claim 1, wherein receiving the trusted connection table from the HIPS comprises the virtual component within the virtual environment receiving a trusted message containing the trusted connection table from the HIPS.

5. The method of claim 4, wherein the trusted message comprises sending a plurality of data according to at least one of a Simple Network Management Protocol version 3 (SNMPv3) and a Network Configuration Protocol (NETCONF).

6. The method of claim 1, wherein the HIPS comprises a physical firewall connected to the virtual environment by a communication network.

7. The method of claim 1, wherein the plurality of connection information comprises a source Internet Protocol (IP) address, a destination IP address, a source port, a destination port, and a protocol.

8. The method of claim 7, wherein the plurality of trusted connection information comprises a trusted source IP address, a trusted destination IP address, a trusted source port, a trusted destination port, and a trusted protocol.

9. The method of claim 8, wherein determining if the plurality of connection information matches the plurality of trusted connection information comprises matching the source IP with the trusted source IP address, matching the destination IP address to the trusted destination IP address, matching the source port to the trusted destination port, matching the destination port to the trusted destination port, and matching the protocol with the trusted protocol.
