Guardian profile: Tim Berners-Lee

Filed under
Web

There are, according to recent figures, more than 35 million web users in the UK today. More than 15 million British homes have internet connections and, thanks to faster broadband technologies, we are living in a radically different world from that which was predicted.

The world wide web has changed millions of lives in little more than a decade. For some it has changed fortunes as well: this week was the 10th anniversary of what is widely acknowledged as the beginning of the dotcom boom - when the web browser firm Netscape floated on the US stock market before ever turning a profit. That sparked a technology goldrush that has transformed modern communication. And while much of the boom was hyperbole, one rock solid fact remains: none of it would have happened if it was not for Tim Berners-Lee.

Sir Tim, named last year as the greatest living Briton, is rightly heralded as the godfather of the web. It was he who, as a physicist working in Switzerland, turned the internet from a disparate collection of academic and military computer systems into an international network. Without his input, arguably, the world would be a far duller place. The global village would still be under construction, technology would still be the preserve of an elite, and revolutionary companies such as Google, Amazon - and even easyJet - would not exist.

BlueBorne Vulnerability Is Patched in All Supported Ubuntu Releases, Update Now

Canonical released today new kernel updates for all of its supported Ubuntu Linux releases, patching recently discovered security vulnerabilities, including the infamous BlueBorne that exposes billions of Bluetooth devices. The BlueBorne vulnerability (CVE-2017-1000251) appears to affect all supported Ubuntu versions, including Ubuntu 17.04 (Zesty Zapus), Ubuntu 16.04 LTS (Xenial Xerus) up to 16.04.3, Ubuntu 14.04 LTS (Trusty Tahr) up to 14.04.5, and Ubuntu 12.04 LTS (Precise Pangolin) up to 12.04.5.

Security: Updates, 2017 Linux Security Summit, Software Updates for Embedded Linux and More

  • Security updates for Tuesday
  • The 2017 Linux Security Summit
    The past Thursday and Friday was the 2017 Linux Security Summit, and once again I think it was a great success. A round of thanks to James Morris for leading the effort, the program committee for selecting a solid set of talks (we saw a big increase in submissions this year), the presenters, the attendees, the Linux Foundation, and our sponsor - thank you all! Unfortunately we don't have recordings of the talks, but I've included my notes on each of the presentations below. I've also included links to the slides, but not all of the slides were available at the time of writing; check the LSS 2017 slide archive for updates.
  • Key Considerations for Software Updates for Embedded Linux and IoT
    The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers. Many of these embedded devices run a variant of embedded Linux; typically, the distribution size is around 16MB today. Unfortunately, the Linux kernel, although very widely used, is far from immune to critical security vulnerabilities as well. In fact, in a presentation at Linux Security Summit 2016, Kees Cook highlighted two examples of critical security vulnerabilities in the Linux kernel: one being present in kernel versions from 2.6.1 all the way to 3.15, the other from 3.4 to 3.14. He also showed that a myriad of high severity vulnerabilities are continuously being found and addressed—more than 30 in his data set.
