• Safer cyberspace through experimental cybersecurity research

    How do cybersecurity experts discover how properly to defend a system or build a network which is secure? As in other domains of science, this process involves hypothesis, experimentation, and analysis — or at least it should. In reality, cybersecurity research can happen in an ad hoc fashion, often in crisis mode in the wake of an attack. A group of researchers has imagined a different approach, one in which experts can test their theories and peers can review their work in realistic but contained environments — not unlike the laboratories found in other fields of science. The researchers issued a report calling for a new generation of experimental cybersecurity research.

  • The mind of a cyberterrorist, a neglected aspect of cybersecurity

    A new study is delving into an aspect of cybersecurity rarely explored before now: the human component. The reason why this topic is lesser known, a leading expert says, is that security professionals become very focused on the technological side of responding to attacks and lack the social psychology background to analyze and understand the human being on the other side of that attack.

  • Protecting the U.S. electrical grid from cyberattack

    Across the United States, 3,200 separate organizations own and operate electrical infrastructure. The widely dispersed nature of the nation’s electrical grid and associated control systems has a number of advantages, but since the late 1990s, cost pressures have driven the integration of conventional information technologies into these independent industrial control systems, resulting in a grid which is increasingly vulnerable to cyberattack, either through direct connection to the Internet or via direct interfaces to utility IT systems. DARPA is soliciting proposal for creating automated systems to restore power within seven days or less after a cyberattack on the grid.

  • Following indictments, China’s military reduces its commercial cybeespionage against American companies

    The People’s Liberation Army (PLA) has reduced its cyberespionage activity targeting American companies since five PLA officers were indicted by the Department of Justice in May 2014. “The indictments had an amazing effect in China, more than we could have hoped for,” said one expert. In April, Obama signed an executive order calling for impose economic sanctions on individuals and entities that take part in or benefit from illicit cyber-activities such as commercial espionage. “If the indictments had the effect of getting the PLA to scale down, then sanctions likely will have a wider effect on other Chinese state-sponsored groups,” says another expert.

  • Low-cost malware detection

    The battle between malware authors and security researchers has changed dramatically in the last few years. The purpose behind malware was often for the sake of a prank, to expose vulnerabilities, or for the sake of spite. Today, malware is more about stealing sensitive data and exploiting information for fraud, identity theft, and other criminal intent. An add-on for antivirus software that can scan across a computer network and trap malicious activity missed by the system firewall is being developed by an international team.

  • Untraceable communication -- guaranteed

    Anonymity networks, which sit on top of the public Internet, are designed to conceal people’s Web-browsing habits from prying eyes. The most popular of these, Tor, has been around for more than a decade and is used by millions of people every day. Recent research, however, has shown that adversaries can infer a great deal about the sources of supposedly anonymous communications by monitoring data traffic though just a few well-chosen nodes in an anonymity network. Researchers have developed a new, untraceable text-messaging system designed to thwart even the most powerful of adversaries.

  • Concerns over attacks on the U.S. electrical grid increase after Paris attacks

    In the aftermath of the 13 November attacks in Paris, U.S. government agencies involved with grid security and utilities are preparing to thwart a major attack on the U.S. electrical grid. Government agencies and utilities believe an attack or series of attacks on the electrical grid of the United States is imminent — more so in the aftermath of the attacks on Paris. They are carrying out drills and exercises to brace for them.

  • Good apps talking to bad Web sites behind your back

    In one of the first studies to analyze behind-the-scenes behaviors of good applications, researchers conducted a large-scale analysis of URLs embedded in 13,500 free android apps downloaded from Google Play. The apps tested were created by reputable developers and downloaded by many people, among them popular social media, shopping, news and entertainment apps. The researchers found that almost 9 percent of popular apps downloaded from Google Play interact with Web sites that could compromise users’ security and privacy; 15 percent talked to bad Web sites (with intentions that vary from harming devices, stealing confidential data or annoying users with spam); and 73 percent talked to low-reputation Web sites(those receiving a Web of Trust rating lower than 60/100).

  • New cybersecurity legislation would shield companies from public records laws

    A legislation which passed both houses of Congress, but has not yet signed into law by the president, aims to encourage companies and organizations to share with the U.S. government information about cyberattacks and cyberthreats they experience –but critics say there is a catch: the legislation would severely restrict what the public can learn about the program.

  • USD launches a new Center for Cyber Security Engineering and Technology

    To address the threats cyberattacks pose to the security, prosperity, and privacy of the United States and its citizens, the University of San Diego announced the creation of its Center for Cyber Security Engineering and Technology. The Center will focus on cybersecurity challenges through education, training, and research.

  • DHS runs many unsecured databases: IG

    DHS Inspector General found that DHS is running dozens of unpatched databases, some of which are rated “secret” and even “top secret.” An audit of the department’s IT infrastructure has found large security gaps, including the fact that 136 systems had expired “authorities to operate” – that is, no one was in charge of keeping them updated. Of the 136, 17 were classified as “secret” or “top secret.”

  • E-mail security is better than it was, but far from perfect

    E-mail security helps protect some of our most sensitive data: password recovery confirmations, financial data, confidential correspondences, and more. A new report finds that e-mail security is significantly better than it was two years ago, but still has widespread issues.

  • Encryption firm tightens access following Paris attacks

    Encrypted communications specialist Silent Circle, after learning that ISIS was recommending two of the company’s products — the encrypted Blackphone handset and Silent Phone applications for private messaging — to the organization’s followers, is taking steps to make it more difficult for terrorists and their followers to use these products.

  • Telegram IM app recalibrates policies after Paris attacks

    Pavel Durov, the creator of the popular instant messaging app Telegram, has said that following the Paris terrorist attacks, his company has blocked dozens of accounts associated with the jihadist Islamic State group. As is the case with other technology companies, Telegram is trying to negotiate the balance between privacy and security: the same privacy-enhancing technology which keeps customers’ communication private, also helps terrorists communicate with each other and plot attacks safe from monitoring and surveillance by intelligence agencies and law enforcement.

  • Paris terrorist attacks reignite debate over end-to-end encryption, back doors

    The exact way the terrorists who attacked France last Friday communicated with each other, and their handlers, in the run-up to the attack is not yet clear, but the attack has prompted law enforcement and intelligence agencies in Europe and the United States to renew their call to regulate the use of new encryption technologies which allow users to “go dark” and make it difficult, if not altogether impossible, to retrieve the contents of communication.
