Open-Source Security Tools Touted at InfoSec

Security

A well-known security consultant on Tuesday urged cash-strapped businesses to consider using free, readily available open-source security tools and applications to help cope with the rising spate of malicious hacker attacks.

In what has become a recurring theme at this year's InfoSec World conference here, president and principal consultant at Sph3r3 LLC Matt Luallen said enterprises must embrace the same hacking tools used by the bad guys to find potential faults and vulnerabilities within critical information infrastructure.

"You can use open-source applications alongside commercial applications [to cut down on costs]," Luallen said during a show-and-tell with dozens of toolsets that can handle anything from fault identification to spam detection to incident response.

"There are some open-source utilities that blow away commercial products, and you should take advantage of them."

"Some of these tools work so well that, at the very least, you should start evaluating them for widespread use in your organization," Luallen said, seeking to dismiss fears that the absence of product support when using open-source utilities could be a deterrent.

"These open-source tools have better product support-it's called Google Groups. If you do a search on Google Groups, in most situations, you'll have an international community available with answers round-the-clock."

"I'm not here to tell you that you should get rid of commercial products. There are some fantastic commercial products out there. However, in many cases, it is practical, cheaper and even better to look for an open-source alternative," Luallen said.

"Remember, the attack utilities are open-source as well. It's important that you understand the tools the bad guys are using to find holes in your system. You have to use those tools, too, and find the same faults."

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.
