CONFIGURING AN ISLAND VIRTUAL SWITCH FOR PROVISIONING OF NETWORK SECURITY SERVICES
Systems, methods, and apparatuses enable a security microservice to provision security services to a resource (e.g., a virtual machine) by assigning the virtual machine to an island virtual switch. An island virtual switch is a virtual switch that does not have a direct connection to a physical link, and instead interfaces with a network traffic interceptor having a connection to a virtual switch with a connection to a physical link, to direct network traffic to and form the assigned virtual machine. The network traffic interceptor performs intercept operations on at least a portion of network traffic between the virtual switch and the island virtual switch associated with the virtual machine in order to perform security operations of the portion of network traffic.
