A team of researchers from the U.S. Army Research Laboratory, the University of Canterbury in New Zealand and the Gwangju Institute of Science and Technology in the Republic of Korea have taken a step toward the development of moving target defense techniques in software-defined networks. This is a demanding cybersecurity research topic, scientists said.

This collaboration grew out of efforts of ARL researchers Dr. Jin-Hee Cho (now at Virginia Tech in the Department of Computer Science), Dr. Terrence J. Moore and Dr. Frederica Nelson reaching out to researchers in Asia Pacific regions through the international collaborative program administrated by the U.S. Army International Technology Center-Pacific.

Cyberattacks - Computer - Systems - Company - Information

Cyberattacks on computer systems are becoming more common. Any company with information on a computer system connected to the internet might become a victim from someone or some group who wants to steal or destroy the company's data for their own use, or for ransom.

This is possible because of the way the Internet is set up, researchers said. In order to access content on a website, a computer needs to know where to ask for the information. Websites have an address, what is known as an internet protocol, or IP, address; however, these are not just used for websites. Every computer connected to the internet has an IP address.

Cyber - Attackers - Time - IP - Addresses

Cyber attackers have time to discover the IP addresses of the computers they think might have valuable information and attack them using code that is more commonly known as computer viruses or worms.

If the computer or system being attacked has a security system, such as a firewall or anti-virus software, it might be able to recognize some code as being bad and prevent itself from being infected.

What cyber attackers do is slightly modify their bad code so it is not recognized until the computer's security system is updated or...
