The presidential campaign is dominated by economic issues, so the question the two candidates invite their audience to ponder is: “Are you better off now than four years ago?”; the question “Are you safer today than you were four years ago” is hardly, if ever, posed; security experts agree that while security challenges posed by China, Iran, and Islamists in Africa have grown, Americans are safer today than they were four years ago because the Obama administration, relative to its predecessor and, has pursued the campaign against terrorism and terrorists more aggressively and more single-mindedly; sustained drone strikes and secretive special operations have weakened al Qaeda considerably over the last four years

In the wake of the terrorist attacks of 11 September 2001, many Americans started driving more due to a fear of flying — and lost their lives in traffic accidents; why did this happen more frequently in some states than in others? Why did Spanish driving habits not change in the same way following the 2004 train bombings in Madrid? Psychologists offer an answer

On the eleventh anniversary of the 9/11 attacks, two statisticians apply statistical methods to try and accurately estimate the probability of a 9/11-size terrorist attack occurring during the next decade; examining the historical data from 1968 to 2007, they show that the likelihood of a 9/11-size attack occurring within this time frame was between 11 and 35 percent; looking forward, the likelihood increase to between 25 and 50 percent – and, under certain circumstances, to 95 percent

Ocean Power Technologies (OPT) has entered into an agreement with DHS Science & Technology Directorate to perform a new round of in-ocean tests on the company’s Autonomous PowerBuoy to demonstrate its use for ocean surveillance

The threat of terrorist attack on American aviation has made the system the focus of intense security efforts, but it is difficult to determine if the benefits outweigh their cost; efficient security policy — a focus on getting the most security for the least cost — should be the priority in an era of fiscal austerity, says a new RAND report

In the years after 9/11 and the 7 July 2005 London bombings, photographers have been waging a war with security personnel of public and private buildings; photographers argue that anything that one can see from the street can be photographed, even if it is a privately owned building, but security people – both private and the police – are worried about terrorists gathering information for a possible attack

Bioterrorism is nothing new, and although medicines have made the world a safer place against a myriad of old scourges both natural and manmade, it still remains all too easy today to uncork a dangerous cloud of germs; DHS’s Science and Technology Directorate (DHS S&T) has scheduled a series of tests in the Boston subways to measure the real-world performance of new sensors recently developed to detect biological agents

Three anti-nuclear activists, led by an 82-year old nun, breached the perimeter security system of the supposedly highly secure Y-2 nuclear facility at Oak Ridge, Tennessee, where nuclear weapons components are manufactured (note that the Oak Ridge National Laboratory [ONRL] is not affiliated with the Y-12 National Security Complex); they then spent several hours in a secure area of the facility, leisurely spray-painting slogans on the facility’s walls – without the facility’s security staff, or the sophisticated $500 million security cameras and sensors, detecting them; to understand what happened at Y-2, we must accept that operator error is an essential problem in national security, and that the problem is pervasive and normal; the only way to deal with the operator error phenomenon is to build redundancies into the system

Thousands of pipe bombs are made each year, and thousands of pipe bomb threats are called into local police and FBI authorities across the country; many are false alarms, but those that are not can be deadly; dismantling a pipe bomb is tricky and serious business, and missteps during the dismantling process can produce catastrophic results
