Systems, methods, and storage media for utilizing software defined networking for a multiple operating system rotational environment, executing on a computing device are disclosed. Some implementations may: receive a request from a user device; modify a packet of the request with a destination address and a port of a first server; forward the modified packet of the request to a controller server; receive a flow modification from the controller server based on the modified packet; and modify further received packets from the user device based on the received flow modification.

Software defined networking multiple operating system rotational environment

Systems and methods for utilizing stream splitting Moving Target Defense (MTD) to provide enhanced computer system communication system security by splitting a data stream in to a plurality of paths is described. In some implementations, Stream splitting MTD, involves splitting a single data stream (e.g., TCP stream) into a plurality of discrete units, then sending and receiving those discrete units from and to different (ideally geographically disparate) receiving servers, with the stream being reassembled on the receiving end. The plurality of discrete units of data include resequencing data. The size of each discrete unit may vary depending on the specific implementation, even down to small unit sizes (e.g., a single packet).

Stream splitting moving target defense

Systems and methods for providing a multiple operating system rotation environment ('MORE') moving target defense ('MTD') computing system are described. The MORE-MTD system provides enhanced computer system security through a rotation of multiple operating systems. The MORE-MTD system increases attacker uncertainty, increases the cost of attacking the system, reduces the likelihood of an attacker locating a vulnerability, and reduces the exposure time of any located vulnerability. The MORE-MTD environment is effectuated by rotation of the operating systems at a given interval. The rotating operating systems create a consistently changing attack surface for remote attackers.
