1. A method, comprising: responsive to a trigger, initiating a security service in a network function virtualization (NFV)-based network system for obfuscating messages transmitted across the NFV-based network system, the security service including: (a) a first obfuscation service component specific to a physical portion of the NFV-based network system that includes a plurality of physical components of the NFV-based network system, the first obfuscation service component including at least one first virtual network function (VNF) that performs a plurality of obfuscation functions including: a first obfuscation function that performs packaging of packets received from multiple of the physical components to form first outgoing communications, a second obfuscation function that performs encryption of the first outgoing communications, a third obfuscation function that performs timing changes of the first outgoing communications, a fourth obfuscation function that performs decoding of first incoming communications, and a fifth obfuscation function that performs unpacking of the first incoming communications, and (b) a second obfuscation service component specific to a cloud-based virtual portion of the NFV-based network system that includes a plurality of virtual services of the NFV-based network system, the second VNF being different from the first VNF, and the second obfuscation service component including the plurality of obfuscation functions including: the first obfuscation function that performs packaging of packets received from multiple of the virtual components to form second outgoing communications, the second obfuscation function that performs encryption of the second outgoing communications, the third obfuscation function that performs timing changes of the second outgoing communications, the fourth obfuscation function that performs decoding of second incoming communications, and the fifth obfuscation function that performs unpacking of the second incoming communications, wherein the security service is transparent with respect to the plurality of physical components and the plurality of virtual services; identifying a communication sent from a source that is one of the plurality of physical components in the physical portion of the NFV-based network system, the communication being directed to one or more of the plurality of virtual services in the cloud-based virtual portion of the NFV-based network system; responsive to the initiating of the security service and the identifying of the communication, directing the communication from the physical portion of the NFV-based network system to the first obfuscation service component specific to the physical portion of the NFV-based network system; responsive to receipt of the communication by the first obfuscation service component, processing the communication by the first obfuscation service component utilizing the first, second, and third obfuscation functions of the plurality of obfuscation functions; sending the processed communication from the first obfuscation service component specific to the physical portion of the NFV-based network system to the second obfuscation service component specific to the cloud-based virtual portion of the NFV-based network system; responsive to receipt of the communication by the second obfuscation service component, processing the communication by the second obfuscation service component utilizing the fourth and fifth obfuscation functions of the plurality of obfuscation functions and sending the communication from the second obfuscation service component to the one or more virtual services in the cloud-based virtual portion of the NFV-based network system; identifying a second communication sent from a second source that is one of the plurality of virtual services in the cloud-based virtual portion of the NFV-based network system, the second communication being directed to one or more of the plurality of physical components in the physical portion of the NFV-based network system; responsive to the initiating of the security service and the identifying of the second communication, directing the second communication from the cloud-based virtual portion of the NFV-based network system to the second obfuscation service component specific to the cloud-based virtual portion of the NFV-based network system; responsive to receipt of the second communication by the second obfuscation service component, processing the second communication by the second obfuscation service component utilizing the first, second, and third obfuscation functions of the plurality of obfuscation functions; sending the processed second communication from the second obfuscation service component specific to the cloud-based virtual portion of the NFV-based network system to the first obfuscation service component specific to the physical portion of the NFV-based network system; responsive to receipt of the second communication by the first obfuscation service component, processing the second communication by the first obfuscation service component utilizing the fourth and fifth obfuscation functions of the plurality of obfuscation functions and sending the second communication from the first obfuscation service component to the one or more physical components in the physical portion of the NFV-based network system.
