By: Justin Lynch President Donald Trump announced in a Dec. 23 tweet that Patrick Shanahan will become acting secretary of defense Jan. 1, replacing outgoing Pentagon chief Jim Mattis two months early. While it is not clear how long Shanahan will remain in the job, he is on the short list of officials who could become the full-time Pentagon chief. Regardless of the length of his tenure, Shanahan, the Pentagon deputy since 2017, has been one of the Pentagon's top advocates for stronger contractor cybersecurity and IT acquisition and will lead the department months after it was given expansive and loosely defined authorities to conduct offensive cyber operations. How Shanahan will handle these greater cyber authorities, even on a temporary basis, remains an open question that will be tested immediately amid evolving challenges, such as an alleged hacking campaign from China. Unclear views on cyber operations In August, the secretary of defense was given the ability to conduct offensive cyber operations without informing the president as long as it does not interfere with the “national interest” of the United States, four current and former White House and intelligence officials have told Fifth Domain. A Pentagon official told Fifth Domain that while there is a general outline of what specific operations may affect the American “national interest,” some details are not explicitly defined. And a review of his public remarks show that Shanahan has not made significant comments about how America should conduct offensive cyber operations. He has shiedaway from giving detailed responses about U.S. Cyber Command. “There are two new war-fighting domains, cyber and space, for which we are developing doctrine and capabilities,” Shanahan said Sept. 19. A spokesperson for Shanahan did not respond to questions from Fifth Domain. Focus on defense contractors As deputy, Shanahan has focused on “re-wiring” the Pentagon. He has called good cybersecurity “foundational” to working with the department. “Cybersecurity is, you know, probably going to be what we call the ‘fourth critical measurement.' We've got quality, cost, schedule, but security is one of those measures that we need to hold people accountable for,” Shanahan said Sept. 19 during an Air Force Association conference. Shanahan's focus on contractor cybersecurity comes as China is believed to be targeting defense contractors, particularly those on the lower end of the supply chain, in an attempt to steal sensitive American secrets, according to intelligence officials and industry executives. Shanahan, however, has placed responsibility among the top defense firms. “I'm a real strong believer that the Tier 1 and Tier 2 leadership has a responsibility to manage the supply chain,” Shanahan said in the Sept. 19 speech. In October, Shanahan was put in charge of a new Pentagon task force to combat data exfiltration that focuses in part on these defense firms. “Together with our partners in industry, we will use every tool at our disposal to end the loss of intellectual property, technology and data critical to our national security,” Shanahan told Fifth Domain in October. A specific area of focus inside the department is finding out which companies are in the Pentagon's supply chain, according to officials involved in the process, but it is not clear if it is specifically part of Shanahan's task force. Inside the Pentagon, Shanahan has also emphasized the need for smarter IT acquisition. In an October. interview with Fifth Domain, Shanahan expressed frustration with the Pentagon's procurement process, but said to expect “a number of things that are foundational to being able to achieve enterprise solutions.” He hinted that those changes are focused on the “right platforms and the right level of integration” that can support high-end computing and artificial intelligence. “I'm super frustrated that we can't go faster on like basic things like the cloud,” Shanahan said. “Most of everything we do is software-driven.” Aaron Mehta contributed to this report. https://www.fifthdomain.com/dod/2018/12/24/how-the-new-acting-pentagon-chief-views-cybersecurity

Whether robots are exploring caves on other planets or disaster areas here on Earth, autonomy enables them to navigate extreme environments without human guidance or access to GPS. The Subterranean Challenge, or SubT, is testing this kind of cutting-edge technology. Sponsored by the Defense Advanced Research Projects Agency (DARPA), the contest concluded its second circuit on Wednesday, Feb. 27. Taking first in the competition was CoSTAR, a 12-robot, 60-person team led by NASA's Jet Propulsion Laboratory (there were also winners declared for a separate, virtual competition). SubT is divided into four circuits spread over three years. With each, teams program their robots to navigate a complex underground course. The first contest, held last August, took place in a mine. For the most recent, called the Urban Circuit, teams raced against one another in an unfinished power plant in Elma, Washington. Each team's robots searched for a set of 20 predetermined objects, earning a point for each find. For the Urban Circuit, CoSTAR earned 16 points; the No. 2 team, with 11 points, was Explorer, led by Carnegie Mellon University. "The goal is to develop software for our robots that lets them decide how to proceed as they face new surprises," said CoSTAR's team lead Ali Agha of JPL. "These robots are highly autonomous and for the most part make decisions without human intervention." CoSTAR, which stands for Collaborative SubTerranean Autonomous Robots, brought machines that can roll, walk or fly, depending on what they encounter. Along the way, the bots have to map the environment and find objects like a warm mannequin that simulates a disaster survivor or a lost cellphone with a Wi-Fi signal. This particular course, which aims to simulate an urban environment, also included a carbon dioxide leak and a warm air vent. Joining the team for the Urban Circuit was a four-legged robot called Spot, which was provided by Boston Dynamics. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, a Caltech professor and JPL research scientist. He is the leader of the Caltech campus section of the CoSTAR team. As the bots explore, they send back video and digital maps to a single human supervisor, who they remained in radio contact with for the first 100 feet (30 meters) or so of the course. They can extend that range by dropping communications nodes, a kind of wireless repeater. Once out of contact, it's up to each robot to decide whether to proceed or backtrack in order to update the team. Each must also rely on fellow robots to access different levels of the course. For example, a wheeled robot might request a quadrupedal one to climb or descend a flight of stairs. "These courses are very, very challenging, and most of the difficulty lies in communicating with the robots after they've gone out of range," Agha said. "That's critical for NASA: We want to send robots into caves on the Moon or Mars, where they have to explore on their own." Mapping caves on the Moon or Mars could identify good shelters for future astronauts. Moreover, if it exists at all, microbial life has a better chance of survival under the surface of Mars or within the icy seas of planetary moons, like Europa, Enceladus and Titan. NASA wants to search for life in these regions, where robots would be frequently out of contact. The next circuit in the Subterranean Challenge will be set in an undisclosed natural cave network this August. A final circuit that blends tunnels, urban environments and natural caves will take place in August of 2021. Teams competing in that final event have the opportunity to win up to $2 million in funding from DARPA. CoSTAR, includes JPL; Caltech, which manages JPL for NASA; MIT; KAIST (Korea Advanced Institute of Science and Technology); Sweden's Lulea University of Technology; and industry partners.
