• Protecting water utilities from terrorist attacks and contaminants

    In 1993, a cryptosporidiosis outbreak in Milwaukee contaminated the city’s water supplies, hastened the deaths of dozens of citizens, made more than 400,000 residents ill, and cost more than $96 million in medical expenses and lost productivity; Sandia’s CANARY software protects water utilities from terrorist attacks and contaminants

  • DHS warns utilities at risk from insider threats

    Last week DHS warned critical infrastructure operators like chemical facilities, nuclear power plants, and electric utility companies that terrorists could be targeting major facilities from the inside; officials cautioned that “violent extremists have, in fact, obtained insider positions,” and that “outsiders have attempted to solicit utility-sector employees” for damaging physical and cyber attacks.

  • Lawmakers blast the Federal Protective Service

    Last week lawmakers held a hearing to investigate the Federal Protective Service’s (FPS) progress in addressing its ongoing problems; the agency has made little progress drawing the ire of lawmakers; in recent years, FPS has suffered from a series of high-profile security failures

  • Studying the Japan quake's impact on soil will improve building design

    The 11 March quake that hit Japan weakened subsurface materials by as much as 70 percent; that nonlinear response from the top layer of the Earth’s crust affected how the movement of faults deep beneath the surface was delivered to buildings, bridges, and other structures; understanding how the soil responds to powerful earthquakes could be important to engineers and architects designing future buildings to withstand the level of acceleration measured in this quake

  • Sensor network to provide early quake alerts

    Researchers from U.S. universities are collaborating to implement a new network of seismic sensors aimed at arming communities with early earthquake detection and warning capabilities; the sensors, no bigger than a Post-it note, are part of a new phase of the Quake-Catcher Network (QCN), a project gathering detailed data to help scientists understand the earthquake process and how to mitigate against its effects

  • Bill to allow DHS to seize authority over U.S. coastlines

    The House is currently considering a bill that would cede control of America’s coastlines to DHS; under the proposed National Security and Federal Lands Protection Act, the Secretary of the Interior would forfeit authority of all public coast lands to the Secretary of Homeland Security, whenever the DHS chief sees fit

  • Melting ice sheets chief cause of rising sea levels

    There are two causes for rising sea levels — melting ice sheets and thermal expansion of warming ocean waters; during the Last Interglacial Period, the former contributed much more to rising sea levels than the latter, a University of Arizona-led team of researchers has found; the results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off

  • U.S. West Coast is rapidly eroding, with pace to accelerate

    The stormy conditions of the 2009-10 El Nino winter eroded beaches from San Diego to Seattle to often unprecedented levels; the higher sea levels expected due to global warming, and potentially even stronger winter storms, will likely to contribute to increased rates of beach and bluff erosion along much of the U.S. West Coast

  • Preparing for the worst

    Nearly three quarters (73 percent) of companies surveyed by AT&T are calling business continuity a priority in 2011, and almost half of them are seriously thinking about using cloud technology to help them deal with terrorism threats, security breaches, the problems that come when the power goes out or the weather turns extreme

  • Malware imported into U.S. on foreign-made components

    A high level DHS official acknowledged that malware built into imported electronic components sold in the United States poses a serious threat to U.S. economy and security; he also said it was a complex threat which the federal government has been trying to address in different ways; Greg Schaffer, acting deputy undersecretary for the National Protection and Programs Directorate at DHS, said the threat is “one of the most complicated and difficult challenges we have”

  • Securing critical infrastructure: portfolio based approach

    Bryan Ware, the CEO and co-founder of Digital Sandbox, a firm that provides risk analysis and management software and services to the private and public sectors, was recently interviewed by Homeland Security NewsWire’s executive editor Eugene Chow; Ware discusses a portfolio based approach to securing critical infrastructure, what the government can do better to protect critical assets, and the dangers of taking a “Whack-a-Mole” tactic with national security threats

  • Volunteers help California build quake sensor network

    Thousands of residents across California are helping the U.S Geological Survey (USGS) build a dense network of seismic sensors across the state; as part of the Quake Catcher Network, Californians are being asked to place 6,000 seismic sensors in their homes to help geologists study earthquakes

  • Fire retardant shows promise -- if given space

    Scientists have demonstrated that the more widely and uniformly dispersed nanoscale plates of clay are in a polymer, the more fire protection the nanocomposite material provides; when polymer — a type of polystyrene, used in packaging, insulation, plastic cutlery, and many other products — is imbued with nanometer scale plates of montmorillonite, the combination can create a material with unique properties or properties superior to those achievable by each component — clay or polymer — on its own
