KELSEY ATHERTON Leaving the browser and its history in a virtual environment spread across any number of servers makes it harder for adversaries to target the military's actual computers or tablets. ALBUQUERQUE: The Defense Information Systems Agency awarded $198.9 million for a Cloud Based Internet Isolation contract to Menlo Security and By Light, the agency announced today. DISA hopes Menlo Security's tech can, by keeping downloads in the cloud, reduce harmful downloads across the entire Pentagon workforce. By keeping browsing inside the cloud, the program will save on bandwidth, and protect against the department's 3.5 million users accidentally downloading malware. It is a kind of “air-gapping,” the style of computer security that keeps networks safe by making sure that computers are not physically connected at all times. Leaving the browser, and all its contained history, in a virtual environment in any of a number of servers makes it harder for adversaries, be they criminals, nonstate actors, or nations, to target the actual computers or tablets used by the military. Internet browsing is mostly downloading files directly to the end-user's computer or mobile device. What the Cloud Based Internet Isolation (CBII) does is make sure that all that downloading happens, not on the end user's computer, but instead in a remotely secured server. “The remote worker will perform the task of going to their net or an Internet based application, that fetch and execute,” Menlo Security VP Mike Fraga says. What is different is that, instead of downloading directly onto the user's device, “getting the information and actually queuing is done in a disposable container in Menlo cloud. And so then we replicate what's happening on the application or the internet down on a remote workers device.” In essence, CBII promises to do all this while making the user experience virtually indistinguishable from having the browser directly running on the computer. Users are functionally interacting with an image of a browser window, instead of the browser itself, but that illusion should be imperceptible. “That's going to significantly reduce the risk in the attack surface,” said By Light VP Jason Cole, “alleviating all the congestion at those Internet access points.” For security purposes, this means that instead of monitoring all traffic for harm on every device, the Pentagon can instead look at the connection between computers and clouds. If a piece of malware was downloaded, it becomes a much smaller haystack of files for the forensics team to go through, since downloading to a computer becomes an active choice, instead of the passive function of browsing. Many of the normal conveniences of browser-based functionality are continued within Menlo's cloud-based environment. Instead of users having to log in anew to every site they visit every time they load the remote cloud, the software “maintains an encrypted cookie-jar in our cloud for each user that largely mirrors how the user's native browser handles cookies,” said Kowsik Guruswamy, Menlo Security CTO. “When a user navigates to a site, Menlo injects the user's site-specific cookies into the isolated browser so they can stay logged in,” Guruswamy continued. “The encryption key for each user's cookie jar is stored in their own browser, such that only they can unlock the contents.” Beyond the security of the environment, the move to cloud-based browsing also promises an overall savings in data use. “We're estimating about a 20% bandwidth reduction for any general web browsing, but then a 50 to 70% bandwidth reduction for streaming media,” said Cole. That savings is valuable everywhere, and is especially valuable in areas where bandwidth is already constrained, like on ships underway or at remote bases with low connectivity. Even in more domestic settings, the pandemic-induced shift to remote work often means users have to send data back through company-owned network infrastructure for security reasons, which eats up time in the process, and comes with risks. “I think companies overall are struggling with not only the latency so that their end users can have a good experience to accomplish their job, but gaps in security based on all that backhauling, and there's some blind spots there,” said Fraga. The servers are, like much of the cloud infrastructure available today, provided through Amazon Web Services. Menlo's approach is already in use with banks like JPMorgan Chase, HSBC, and AmEx. “Isolation overall is an innovative technology,” said Fraga. Isolation, in the fashion promised by cloud-based browsing, is a preventative technology. It reduces the number of paths into computers, making it easier for other detection solutions to find the fewer threats that might slip through. https://breakingdefense.com/2020/09/fewer-threats-more-bandwidth-disa-awards-199m-for-cloud-browsing/

By: Jen Judson WASHINGTON — The request for proposals from industry for the U.S. Army's optionally manned fighting vehicle, or OMFV, intended to replace the Bradley Infantry Fighting Vehicle, has hit the street and allows for greater flexibility for foreign companies to compete. In the service's second stab at holding a competition for OMFV, the Army is driving as much flexibility as it can across the board, from avoiding stringent requirements in favor of loose characteristics and creating a phase for industry to design concepts without much company investment that will form requirements along the way. The Army's previous attempt required the delivery of physical bid samples, which hamstrung foreign competitor Rheinmetall of Germany and drove Bradley-maker BAE Systems to avoid the competition. Ultimately, the service received just one bid sample from General Dynamics Land Systems, which forced the Army to rethink the effort and come back with a new approach. The OMFV competition has foreign industry jumping to join in with new and modernized platforms, and the Army appears to be ditching much of the restrictions that would typically keep them out. Rheinmetall has already partnered with American firms Raytheon and Textron to solidify its participation in the competition, but many other companies are poised to submit bids to design concepts. The pool needs to be deep because the Army anticipates awarding up to five contracts to design platforms. “The challenges we've typically had in getting foreign participation is we often have a lot of classified material that we release up front, and we have some detailed specification that has very detailed performance requirements that's classified,” Brig. Gen. Glenn Dean, the new Army program executive officer for ground combat systems, said in a Dec. 18 press briefing. Foreign competitors “have to have clearances in place to be able to take that information,” Dean said. This means foreign companies must either be partnered with a prime contractor in the United States, have a subsidiary stateside, or have other clearances that take time to get through the approval process in order to exchange the classified information. Working through consortiums, which the Army regularly does, also makes it hard for foreign contractors to come through the door, Dean said. This time, the Army isn't working with a consortium and is using a more traditional federal acquisition regulation-based contract, according to Dean. Furthermore, he said, classified reports will not be required in order to submit a bid or receive an initial design contract award. “We've eliminated the limitation on primes and, because we don't have classified information we are providing at the front end, that allows us to share more broadly and gives those companies time if they're going to continue to play as lead, to establish their facilities, clearances and have the necessary structures in place to receive classified information when we get to that point,” he said. Dean expects more classified requirements to kick in toward the end of the concept design phase where requirements begin to take shape, which translates to specifications. “Obviously, every company is going to make their own determination about what strengths and partners may bring to the table, whether they want to come in as a sub, whether they want to be prime with a bunch of U.S. subs,” Dean said, “but the response has been very promising.” He also said there is strong interest from abroad. “I would say that we at least heard from or have participation ... from all the major companies in the West capable of doing a full combat vehicle. Companies from Israel, South Korea, Singapore, Germany, in addition to companies both you're familiar with in the U.S. who've [supplied] combat vehicles, but also some companies that operate in the defense space but haven't traditionally been combat vehicle suppliers,” he said. “We will see how many of them ultimately decide they want to throw their hat in the ring and participate. I think we've done what we need to do to make it as open at an initial point.” Sources following the competition are expecting to see participation from South Korea's Hanwha, which is in a head-to-head competition in Australia with Rheinmetall to produce a new infantry fighting vehicle. Germany-based Krauss-Maffei Wegmann has also touted an infantry fighting vehicle option, most recently at the last in-person Association of the U.S. Army's annual conference in Washington, D.C., in 2019. Belgium's CMI Defense is also rumored to be forging a partnership with a U.S. prime to participate in the competition. Now that the solicitation has been posted to Beta.Sam.Gov, companies have until April 16, 2021, to submit a conceptual bid. The Army will award contracts in July, according to Dean, which will kick off 15 months of funded work. During the phase, industry will work on designs without bending metal that will inform an abbreviated capabilities development document — or an initial set of requirements. Once the design phase ends, the Army will take a pause and then open the competition back up for a more detailed design effort ahead of prototyping, where up to three bids will be selected to proceed. The detailed design phase will be executed over the course of fiscal 2023 and fiscal 2024. The prototyping phase will begin in FY25, according to slides presented at the OMFV industry day. Vehicle testing will begin in FY26 and wrap up in FY27, with a production decision planned for the fourth quarter of FY27. Full-rate production is expected to begin in the second quarter of FY30. In parallel to the concept design phase, the Army will develop an open architecture for OMFV. An open architecture has risen to the top of the OMFV planner's list of required capability, particularly after seeing the need to be networked with other capabilities across the battlefield and at the forward edge at Project Convergence at Yuma Proving Grounds, Arizona, over the summer. The Army will establish a voluntary consortium beginning in January 2021 that will represent industry, government and academia in order to develop such an open architecture, according to the statement. https://www.defensenews.com/land/2020/12/18/bradley-replacement-request-for-proposals-hits-street-with-flexibility-for-foreign-participation/
