  Pentagon spending could lead to consolidation of cybersecurity industry

  By: Justin Lynch Spurred in part by Russia's campaign of hybrid warfare in Ukraine, the Pentagon will purchase more electronic warfare equipment, a move that could lead to consolidation in the cybersecurity industry, an analyst said in a new report. Russia's use of electronic warfare combined with conventional combat tactics during its 2015 invasion of Ukraine exposed how the Department of Defense needed to increase its spending on cybersecurity, Brad Curran, an analyst at Front & Sullivan told Fifth Domain. Greater use of offensive cyber and electronic weapons by Russia means that the U.S. is expected to boost defense of its communications systems, and possibly look to increase its own offensive weapons. A September report from Frost & Sullivan projected a 2.9 percent compound annual growth rate in cybersecurity spending from the Pentagon through 2023. Securing electronic communications “is a high priority,” Curran said. The Defense Department is “just getting started” and it will be “a continuous effort to make sure our combat networks are secure.” The focus could benefit firms like Raytheon, which have invested heavily in electronic warfare, Curran said. Curran said that government purchases of enterprise systems will likely stay the same or even shrink because many of the acquisitions are meant to boost efficiency. One example is the government's investment in the cloud. But he predicts an increase in purchases of electronic warfare and offensive cyber capabilities, which will favor larger defense firms. The result will be consolidation of the cybersecurity industry among the biggest companies. During the Black Hat conference, one cybersecurity firm described the industry as “cut-throat” and added they expected industry consolidation because of purchases from the largest contractors. In 2017, the Pentagon awarded more than $1.22 billion to cyber contractors. That money went to 69 prime contractors and 50 different companies. The Pentagon's 2019 budget request for cybersecurity totals $3.6 billion, according to the report, half of which is dedicated to operations and management. The Air Force has the largest share of cybersecurity programs, at $2.19 billion. Booz Allen Hamilton was the top recipient of public contracts from the Pentagon in 2017 with a total of $115.4 million in awards, according to the report. In August, the Pentagon awarded Booz Allen Hamilton a $91 contract to manage cybersecurity for the Ballistic Missile Defense System. But while artificial intelligence will be an area that the U.S. government focuses its investments on the future, Curran said it is not currently a major factor in acquisition. “The future is AI but right now it is more of a concept," he said. https://www.fifthdomain.com/industry/2018/09/17/pentagon-spending-could-lead-to-consolidation-of-cybersecurity-industry

  Is this the new wave of submerged communications?

  By: Kelsey Atherton The ocean hides what it contains, and it is in that hiding that submarines have their power. Lurking under seas, at first with just enough capability for an attack run and now with the ability to lurk for months at a time, submarines remain power out of reach, unseen until engaged in combat or resupplying in a friendly port. That stealth comes at a cost, however, besides the simple perils of existing underwater. When submerged, submarines are more or less on their own until they resurface again, since radio waves do not travel well through seawater. Or they are for now. New research by MIT, presented at a conference in late August, devised a way for submerged submarines to communicate wirelessly with people on the surface by combining hydroacoustics and acoustic radars. Presently, submarines communicate either across normal radio frequencies when surfaced or through hydroacoustic signals and listening posts underwater that can transmit the messages back to counterparts on shore. Very and extremely low-frequency radio waves can be transmitted in a way that submarines can listen to below the surface, but it's a one-way form of communication, from stations on land to submarines. To get something responsive, with the flexibility to communicate away from static seabed hydrophones, needs something else. Specifically, it needs a way to combine hydroacoustic transmission from the submarine through water that can then be converted into a useful data. “We present a new communication technology, translational acoustic-RF communication (TARF),” write paper authors Francesco Tonolini and Fadel Adib of the MIT Media Lab. “TARF enables underwater nodes to directly communicate with airborne nodes by transmitting standard acoustic signals. TARF exploits the fact that underwater acoustic signals travel as pressure waves, and that these waves cause displacements of the water surface when they impinge on the water-air boundary. To decode the transmitted signals, TARF leverages an airborne radar which measures and decodes these surface displacements.” In testing, they demonstrated that the communication technique can transfer data at standard underwater bitrates up to 400bps, and even do so with surface waves 6.3 inches crest-to-crest, or 100,000 times larger than the surface perturbations made by the acoustic transmitter. Right now, this communication is one-way. While the signal transmitted up from the water produces useful information at the boundary with the air, a signal transmitted through the air downwards would disintegrate on integration with water. This one-way is distinct from previous forms of communication with submarines, however, as it lets the submarine talk without revealing its position to surface sensors. Despite the limitations, and the earlierness of the research, Tonolini and Adlib see a bright future for the technology, as a way to enable a host of new technology in machines. The technology, they write, can enable “many applications including submarine-to-drone communication, deep-sea exploration, and subsea IoT (Internet of Things). https://www.c4isrnet.com/c2-comms/2018/08/28/mit-discovers-way-for-submarines-to-talk-to-drones
