• New technology proves effective in thwarting cyberattacks on drones

    Engineering researchers from the University of Virginia and the Georgia Institute of Technology have successfully flight-tested scenarios which could threaten drones, including ground-based cyber-attacks. The demonstration of U.Va’s System-Aware Cybersecurity concept and Secure Sentinel technology was part of a research project led by U.Va. engineers to detect and respond to cyber-attacks on unmanned aerial systems.

  • Invisibility cloak closer to reality: Concealing military airplanes, and even people

    Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, acoustic, and other types of waves in ways not possible in nature. Now, Hao Xin, a professor of electrical and computer engineering at the University of Arizona, has made a discovery with these synthetic materials that may take engineers one step closer to building microscopes with superlenses that see molecular-level details, or shields that conceal military airplanes and even people.

  • Yemen upheaval hobbles U.S. counterterrorism efforts there

    Following the abrupt resignation of Yemen’s president, prime minister, and cabinet after Iran-backed Shi’a Houthi rebels took over the presidential palace, the United States has halted some counterterrorism operations against al-Qaeda militants operating inside the country. The move has dealt a blow to what President Barack Obama recently called a successful counterterrorism partnership between Yemen’s president Abd Rabbo Mansour Hadi and the United States. “The [Yemeni government’s] agencies we worked with . . . are really under the thumb of the Houthis. Our ability to work with them is not there,” said a senior U.S. official closely involved in monitoring the situation.

  • U.S.-Russian nuclear security cooperation victim of growing bilateral tensions

    One of the greatest benefits brought about by the end of the cold war was the agreement been the United States and the former Soviet republics to cooperate closely in securing the large, and not-always-well-protected, Soviet nuclear stocks. The 1991 Cooperative Threat Reduction agreement, aka the Nunn-Lugar program after the two former senators — Sam Nunn [D-Georgia] and Richard Lugar [R-Indiana]) — who persuaded fellow lawmakers to fund it, has facilitated to achievement of important security measures: dismantling of thousands of nuclear warheads, securing facilities in Russia where weapon-grade material is stored, and finding suitable jobs for tens of thousands of Russian nuclear scientists, engineers, and technicians. More than two decades of cooperation in guarding weapons-grade stockpiles have now come to an end, the result of tensions over Russia’s role in Ukraine. Experts say the end of U.S.-Russia nuclear cooperation leaves the world “a more dangerous place.”

  • The many problems with the DEA's bulk phone records collection program

    Think mass surveillance is just the wheelhouse of agencies like the NSA? Think again. One of the biggest concerns to come from the revelations about the NSA’s bulk collection of the phone records of millions of innocent Americans was that law enforcement agencies might be doing the same thing. It turns out this concern was valid, as last week the government let slip for the first time that the Drug Enforcement Agency (DEA) had also been collecting the phone records of Americans in bulk since the 1990s.

  • Drawing disaster response lessons by comparing quake responses

    Following the devastating 2011 Great East Japan Earthquake which hit the Tohoku region of Japan, many local and provincial governments rushed to aid the people in the area with personnel and materials, providing important relief in a time of crisis. At a recent symposium, some were comparing the response to the 2011 disaster to the response to the Great Hanshin-Awaji Earthquake of 1995 in order to draw lessons and offer guidelines in effective crisis management.

  • European govts. urge U.S. tech companies to remove terrorist-related postings from sites

    The terror attacks in Paris have led French and German authorities to call on U.S. tech firms to help identify terrorist communications and remove hate speech from social media sites. The United Kingdom has also, for several months now, pressed Internet firms to be proactive in removing extremist content such as videos of sermons by radical Islamic preachers or recruitment material, from their sites. These recent requests for more cooperation between U.S. tech firms and European governments contrast with calls from many of the same governments who, following the Edward Snowden leaks, criticized U.S. tech firms for being too close to law enforcement agencies.

  • Researchers try to develop a methodology for predicting terrorist acts

    While counterterrorism agencies rely on surveillance and other forms of classified data to predict terrorist attacks, researchers and analysts are attempting to define what terrorism is and how it has evolved over time in order better to identify trends and patterns in terrorist activities. This better understanding may help predict the next major attack. Reliable predictions would be helpful not just for counterterrorism experts, but also for insurance underwriters who must consider the terrorism risk faced by large projects.

  • Former head of MI6 calls for new surveillance pact between governments and ISPs

    The former head of British intelligence agency MI6, Sir John Sawers, has called for a new surveillance pact between Internet companies and U.S. and U.K. security services. Both groups could work together as they had in the past to prevent a repeat of terror events such as the recent Paris attacks, he said. American and British law enforcement and intelligence agencies are urging major Internet companies to provide backdoors or access to encrypted e-mails and other forms of Web communications. “I think one benefit of the last eighteen months’ debate [since Snowden’s leaks were made public] is that people now understand that is simply not possible [to keep the public secure without surveillance] and there has to be some form of ability to cover communications that are made through modern technology,” Sawers said.

  • Europe to tackle Jihadist radicalization in prison

    The problem of prison radicalization is raising complicated questions for lawmakers and security officials across Europe. One problem: Thousands of Europeans have joined Islamic State in Syria and Iraq, and experts say that if apprehended upon returning home, these jihadists will be interned in European jails and continue their mission of radicalizing others, leading to an intensification of the problem of prison radicalization.

  • Belgium terror raids and Paris attacks reveal urgent need for pan-European security

    In the immediate aftermath of major attacks in Paris, counter-terrorism raids in Belgium saw two suspected terrorists killed and another arrested. These incidents have dramatically raised the sense of insecurity across Europe — and they’ve done so at a time when Europe’s security infrastructure is struggling to cope with the threats it faces. European security agencies, both internal and external, must urgently improve their co-operation and co-ordination. After all, Europe’s security challenges know no borders, and they must be dealt with as such. The recent counter-terrorism operations and arrests across Europe show that security agencies are moving toward quicker and sharper preventative action. What they do not demonstrate is that there is yet any seriously coordinated approach to European security. Achieving that is central to reducing the sense of insecurity across Europe at a frightening and dangerous time. But there is little sign Europe is confident about how to do it without undermining the very freedoms it is trying to protect.

  • Police chiefs, sheriffs in major U.S. cities support immigration executive order

    Twenty-seven chiefs of police and sheriffs from U.S. cities — including Los Angeles, Dallas, Denver, and Washington, D.C.— have joined the Major Cities Chiefs Associationto defend President Barack Obama’s executive order which extends deferred deportation to about five million undocumented immigrants. Many law enforcement officers around the country argue that Obama’s order will improve public safety by allowing many undocumented immigrants to feel secure enough to approach local police. They are more likely to report crime without fear of deportation, police chiefs and sheriffs assert.

  • Revolutionary weapon to be showcased at Future Force EXPO

    The Electromagnetic Railgun program continues to move toward scheduled at-sea testing in 2016. Its revolutionary technology relies on electricity instead of traditional chemical propellants, with magnetic fields created by high electrical currents launching projectiles at distances over 100 nautical miles — and at speeds that exceed Mach 6, or six times the speed of sound. The Railgun will play a significant role in the future of the U.S. Navy, and it will be on display to the public for the first time on the East Coast 4-5 February at the Naval Future Force Science and Technology (S&T) EXPO in Washington, D.C.

  • No technological replacement exists for bulk data collection: Report

    No software-based technique can fully replace the bulk collection of signals intelligence, but methods can be developed more effectively to conduct targeted collection and to control the usage of collected data, says a new report from the National Research Council. Automated systems for isolating collected data, restricting queries that can be made against those data, and auditing usage of the data can help to enforce privacy protections and allay some civil liberty concerns, the unclassified report says.

  • Keeping citizens safe while respecting their right to privacy

    Surveillance is an increasingly common – and sometimes controversial – activity, designed fundamentally to protect public and property. The rapid increase in information gathered by surveillance cameras however has led to spiraling costs in terms of storage filtering and data checking, and has also led to concerns that innocent citizens are routinely being tracked. Using innovative new technology, EU-funded researchers have reconciled the need for robust surveillance with the right to privacy.
