Worms could dodge Net traps

Security

In a pair of papers presented at the Usenix Security Symposium here Thursday, computer scientists said would-be attackers can locate such sensors, which act as trip wires that detect unusual activity. That would permit nefarious activities to take place without detection.

Internet sensor networks, such as the University of Michigan's Internet Motion Sensor and the SANS Internet Storm Center, are groups of machines that monitor traffic across active networks and chunks of unused IP space. The sensor networks generate and publish statistical reports that permit an analyst to track the traffic, sniff out malicious activity and seek ways to combat it.

Just as surveillance cameras are sometimes hidden, the locations of the Internet sensors are kept secret. "If the set of sensors is known, a malicious attacker could avoid the sensors entirely or could overwhelm the sensors with errant data," a team of computer scientists from the University of Wisconsin wrote in its award-winning paper titled "Mapping Internet Sensors with Probe Response Attacks."

But the Wisconsin researchers discovered that the sensor maps furnish just enough information for someone to create an algorithm that can map the location of the sensors "even with reasonable constraint on bandwidth and resources," John Bethencourt, one of the paper's authors, said in his presentation.

Collaboration Events: Pakistan Open Source Summit, GNOME+Rust Hackfest, DataworksSummit Berlin

  • Pakistan Open Source Summit 2018 concludes [Ed: Not about software]
    A large number of attendees from industry, academia, government, and students participated in the summit. Portuguese Ambassador to Pakistan Dr Joao Sabido Costa was the chief guest at the opening ceremony while former Naval Chief Admiral (r) Asif Sandila graced the occasion as the chief guest at the closing ceremony.
  • ‘Open Summit key to create industry-academy linkages’
    Ambassador of Portugal to Pakistan Dr Joao Sabido Costa has said that events such as the Open Source Summit are excellent for spreading awareness and for creating industry-academia linkages and enhancement of the information technology. He stated this while addressing a concluding ceremony of the two-day informative ‘Pakistan Open Source Summit 2018’ attended by large number of people from industry, academia, government and students. Former naval chief Admiral (R) Asif Sandila co-chaired the concluding session. Dr Joao Sabido Costa said that the organisations should utilise open source platforms to build their IT infrastructures in future. To build open source culture in Pakistan, he recommended roadmap with future activities and timelines for spreading open source.
  • Madrid GNOME+Rust Hackfest, part 2
    Yesterday we went to the Madrid Rust Meetup, a regular meeting of rustaceans here. Martin talked about WebRender; I talked about refactoring C to port it to Rust, and then Alex talked about Rust's plans for 2018. Fun times.
  • DataworksSummit Berlin - Wednesday morning
    Data strategy - cloud strategy - business strategy: Aligning the three was one of the main themes (initially put forward in his opening keynote by CTO of Hortonworks Scott Gnau) thoughout this weeks Dataworks Summit Berlin kindly organised and hosted by Hortonworks. The event was attended by over 1000 attendees joining from 51 countries. The inspiration hat was put forward in the first keynote by Scott was to take a closer look at the data lifecycle - including the fact that a lot of data is being created (and made available) outside the control of those using it: Smart farming users are using a combination of weather data, information on soil conditions gathered through sensors out in the field in order to inform daily decisions. Manufacturing is moving towards closer monitoring of production lines to spot inefficiencies. Cities are starting to deploy systems that allow for better integration of public services. UX is being optimized through extensive automation.

10 Great Linux GTK Themes For 2018

Customization is a big part of the Linux experience, and your desktop theme is no exception. The world of Linux desktop themes is an ever-evolving one, with new ones replacing old favorites all the time. Of course, the desktop environments and GTK itself are always changing, so that adds another dynamic element to consider. That said, some of the best desktop customization happens on the simplest desktop environments, like XFCE. As of now, in early 2018, there are some really excellent GTK themes available. These themes aren’t ranked in any particular order. That comes down to a matter or preference. Any one of them can add a whole new look to your GTK-based desktop. Read more
