Software Defined Networking Multiple Operating System Rotational Environment—Moving-Target Defense (SMORE-MTD) (ANL-SF-18-007)

SDN Multiple Operating System Rotational Environment (SMORE) utilizes software defined networking (SDN) to programmatically switch the flow of packets from users to a given set of servers. By periodically switching which servers respond to user requests.

Cybersecurity issues are a day-to-day struggle for businesses and organizations. Keeping information secure can be a herculean task. SMORE-MTD, developed by Argonne’s Joshua Lyle and Nate Evans with laboratory funding, defends against cybersecurity attacks by using software-defined networking to manipulate network paths that service user requests.

By randomly selecting which server and service will respond to a given user’s request, SMORE-MTD makes it more difficult for an attacker to identify which services to attack. SMORE-MTD also increases organizations’ resilience by preventing an attacker exploit from being routed to the vulnerable software, forcing attackers into repeated attacks that are more likely to be noticed. SMORE-MTD also eliminates the need to install and maintain configuration software on each host in rotation, which reduces complexity and increases the amount of software available for use.
