    Steel costs for sixth patrol vessel could be steeper

    Andrea Gunn (agunn@herald.ca) Ongoing steel and aluminum tariffs between the United States and Canada will not drive up costs for the first five Arctic and Offshore Patrol Ships, but could contribute to the final price tag for the sixth, the Department of National Defence says. There have been tariffs in place on imports of Canadian steel and aluminum to the U.S. of 25 per cent and 10 per cent respectively since the end of May. In response, Canada implemented its own dollar-for-dollar duties on steel and aluminum being imported from the U.S. Both the American tariffs and Canadian countermeasures remain in place, even with a new tentative agreement to replace NAFTA. On Tuesday, Prime Minister Justin Trudeau confirmed the signing of the new trilateral trade deal was not contingent on the lifting of those tariffs. In an emailed statement, Department of National Defence spokesperson Ashley Lemire said these tariffs will not have an impact on the cost of the first five Arctic and Offshore Patrol Ships (AOPS) being built by Irving Shipbuilding as part of the National Shipbuilding Strategy. Lemire said most, if not all, of the steel has already been purchased for these vessels and none of it comes from the U.S. “As part of its contract with the Government of Canada, Irving Shipbuilding Inc. is responsible for the procurement of steel used for the construction of the Arctic and Offshore Patrol Ships,” Lemire said in an email. “Irving procured the majority of steel from a foreign supplier who sourced it from Europe and, to a lesser extent, from China. A small amount of steel was procured in Canada.” Lemire said for the sixth AOPS, which the government confirmed plans to build last week, the department has planned and budgeted for the risk of increased steel and aluminum prices. Earlier this week a DND spokesperson said buying a sixth AOPS will increase the cost of the $2.3 billion project by about $810 million. Of that, $250 million is set aside for “adjustments” — things like labour rates, inflation, and exchange rates. Lemire said any additional steel costs will come from that $250 million fund. David Perry, senior analyst with the Canadian Global Affairs Institute, said the materials needed to build a navy vessel are so specialized that it's not uncommon for governments to do advanced purchases “There's a limited supply; you can't just go and call it up at the last minute kind of thing,” he said. Perry said in the case of the AOPS, having a separate fund set aside for potential cost increases — rather than paying the company a higher contract price to assume all the liability for changes in commodity or labour prices — will likely save taxpayers money if costs do go up. Ian Lee, associate professor at Carleton University's Sprott School of Business told The Chronicle Herald the federal government is lucky to have avoided any major increases with the AOPS. But, Lee said, if the tariffs remain in place, they are likely to impact future builds either directly or indirectly. “It's not going to affect the (AOPS) program but it's still a burden on the economy it's going to be passed on through the cost of doing business,” he said. This is perhaps concerning given the most expensive build of the National Shipbuilding Strategy — the Canadian Surface Combatant — is on the horizon. But how much that project would be impacted if tariffs remain in place is anybody's guess, Lee said. “Historically governments have been very, very involved in the shipbuilding industry with subsidies, and offsets and that sort of thing, so it's hard to predict how it might affect future builds,” he said. “It's not a normal competitive market like the stock market or most commodities.” That said, Lee said there will likely be a big push on the federal government's part to get the tariffs sorted ahead of the upcoming election. “Generally speaking when you look at the trade agreements that have been signed in the last 10 or 20 years whether it was the original NAFTA, CETA or the TPP, one of the first things and most important things you do is reduce or eliminate tariffs,” he said, “I think it's going to make it more difficult for Mr. Trudeau and his government to defend this in the fall 2019 election, that's why I think they're going to be working assiduously to try and remove them.” https://www.thechronicleherald.ca/news/local/steel-costs-for-sixth-patrol-vessel-could-be-steeper-257534/

  • Hacker Community to Take on DARPA Hardware Defenses at DEF CON 2019

    Hacker Community to Take on DARPA Hardware Defenses at DEF CON 2019

    This month, DARPA will bring a demonstration version of a secure voting ballot box equipped with hardware defenses in development on the System Security Integrated Through Hardware and Firmware (SSITH) program to the DEF CON 2019 Voting Machine Hacking Village (Voting Village). The SSITH program is developing methodologies and design tools that enable the use of hardware advances to protect systems against software exploitation of hardware vulnerabilities. To evaluate progress on the program, DARPA is incorporating the secure processors researchers are developing into a secure voting ballot box and turning the system loose for public assessment by thousands of hackers and DEF CON community members. Many of today's hardware defenses cover very specific instances or vulnerabilities, leaving much open to attack or compromise. Instead of tackling individual instances, SSITH researchers are building defenses that address classes of vulnerabilities. In particular, SSITH is tackling seven vulnerabilities classes identified by the NIST Common Weakness Enumeration Specification (CWE), which span exploitation of permissions and privilege in the system architectures, memory errors, information leakage, and code injection. “There are a whole set of cyber vulnerabilities that happen in electronic systems that are at their core due to hardware vulnerabilities – or vulnerabilities that hardware could block,” said Dr. Linton Salmon, the program manager leading SSITH. “Current efforts to provide electronic security largely rely on robust software development and integration, utilizing an endless cycle of developing and deploying patches to the software firewall without addressing the underlying hardware vulnerability. The basic concept around SSITH is to make hardware a more significant participant in cybersecurity, rather than relegating system security only to software.” Under the SSITH program, researchers are exploring a number of different design approaches that go well beyond patching. These include using metadata tagging to detect unauthorized system access; employing formal methods to reason about integrated circuit systems and guarantee the accuracy of security characteristics; and combining hardware performance counters (HPCs) with machine learning to detect attacks and establish protective fences within the hardware. One team from the University of Michigan is developing a novel security approach that changes the unspecified semantics of a system every 50 milliseconds. Currently, attackers continuously probe a system to locate these undefined sections and, over time, are able to create a system map to identify possible hacks. By changing the construct every 50 milliseconds, attackers do not have enough time to find those weaknesses or develop an accurate representation of the system as a whole. To evaluate the hardware security concepts in development on the SSITH program, DARPA – working with Galois – is pursuing a voting system evaluation effort to provide a demonstration system that facilitates open challenges. The program elected to use a voting system as its demonstration platform to provide researchers with an accessible application that can be evaluated in an open forum. Further, the topic of election system security has become an increasingly critical area of concern for the hacker and security community, as well as the United States more broadly. “DARPA focuses on creating technologies to enhance national defense, and election system security falls within that remit. Eroding trust in the election process is a threat to the very fabric of our democracy,” noted Salmon. While protecting democracy is a critical national defense issue, SSITH is not trying to solve all issues with election system security nor is it working to provide a specific solution to use during elections. “We expect the voting booth demonstrator to provide tools, concepts, and ideas that the election enterprise can use to increase security, however, our true aim is to improve security for all electronic systems. This includes election equipment, but also defense systems, commercial devices, and beyond,” said Salmon. During DEF CON 2019, the SSITH voting system demonstrator will consist of a set of RISC-V processors that the research teams will modify to include their SSITH security features. These processors will be mounted on field programmable gate arrays (FPGAs) and incorporated into a secure ballot box. Hackers will have access to the system via an Ethernet port as well as a USB port, through which they can load software or other attacks to challenge the SSITH hardware. Since SSITH's research is still in the early stages, only two prototype versions of the 15 processors in development will be available for evaluation. “At this year's Voting Village, hackers may find issues with the processors and quite frankly we would consider that a success. We want to be transparent about the technologies we are creating and find any problems in these venues before the technology is placed in another venue where a compromise could be more dangerous,” said Salmon. Following DEF CON 2019, the voting system evaluation effort will go on a university roadshow where additional cybersecurity experts will have an opportunity to further analyze and hack the technology. In 2020, DARPA plans to return to DEF CON with an entire voting system, which will incorporate fixes to the issues discovered during the previous year's evaluation efforts. The 2020 demonstrator will use the STAR-Vote system architecture, which is a documented, open source architecture that includes a system of microprocessors for the voting booth, ballot box, and other components. It also includes a verifiable paper ballot, providing both digital and physical representations of the votes cast within the booth. “While the 2020 demonstrator will provide a better representation of the full attack surface, the exercise will not result in a deployable voting system. To aid in the advancement of secure election equipment as well as electronic systems more broadly, the hardware design approaches and techniques developed during the SSITH program will be made available to the community as open-source items,” concluded Salmon. https://www.darpa.mil/news-events/2019-08-01

    CAE releases its first Business Jet Pilot Demand Outlook: 50,000 new business jet pilots required over the next 10 years

    CAE released today at the 2018 National Business Aviation Association (NBAA) convention and exhibition its 2018 CAE Airline and Business Jet Pilot Demand Outlook. This is an update to last year's report, which provides, for the first time, a business jet pilot demand forecast. The renewed 10-year view offers fleet operators key insights on the future need for professional pilots in both business and commercial aviation, building on the markets' key drivers, variables and trends. The report demonstrates that the active business jet pilot population will reach 65,000 by 2028, which represents an increase of 18%, with a turnover rate of almost 100%. More specifically, 10,000 new business jet pilots will be required to sustain growth and 40,000 new business jet pilots will be needed to support retirement attrition across the segment over the next decade. “The CAE Airline and Business Jet Pilot Demand is a one-of-a kind report. Our 2018 update builds on last year's analysis while introducing for the first time a business jet pilot forecast and shedding light on ways the aviation industry can cope with this demand,” said Marc Parent, CAE's President and Chief Executive Officer. “Today's soaring pilot demand is a reality that we must all face. As the leading training organization in the world, we are honoured to offer our partners the training solutions they need to face this rising demand.” The 2018 CAE Airline and Business Jet Pilot Demand Outlook is available for download at www.cae.com/civil-aviation. https://www.cae.com/news-events/press-releases/cae-releases-its-first-business-jet-pilot-demand-outlook-50000-new-business-jet-pilots-required-over-the-next-10-years
