A third of virtual servers are zombies

New research finds that 25% of all physical servers -- and 30% of all virtual servers -- are comatose. These are systems that have no activity in the last six months.The problem with comatose, or zombie, physical servers is well known. Past studies have routinely put the number of undead enterprise physical servers in the 20% to 30% range. But this latest research looked at virtual servers as well, and they may represent a significant cost to IT departments.[ Further reading: The march toward exascale computers ] That's because users may be paying licensing fees on their virtual servers, as well as on the software they support, said the researchers.To read this article in full or to leave a comment, please click here

Q&A Citrix CSO: How to deal with security across multiple generations of employees

Citrix’s CSO Stan Black has been in the cybersecurity field for 20 years. He has seen generations of employees come and go at the software and data security company.

Install the CORE Network Emulator from source code

To install the CORE network emulator in recently released Linux distributions, including Ubuntu 16.04 and later, you must install it from source code. There is a bug in CORE that prevents Quagga from starting its routing daemons in newer Linux distributions that is fixed in the latest version of the source code. However, the fix is not in the pre-built CORE packages available on the CORE web site, nor in the Ubuntu repository.

To further create problems, the CORE web site contains old versions of source code and does not point to the latest version of CORE on Github.

Also, the Ubuntu maintainers will remove CORE packages from the Ubuntu repository in the near future because CORE allows unprivileged users to access root privileges, which creates a security problem if CORE is run on a computer used by more than one person.

In this post, I provide a detailed procedure to install CORE from the source code on Github, and to set up your system to run network experiments using the CORE network emulator.

Install CORE from Github

The latest version of CORE is available on Github. To install CORE, first install some prerequisite packages that allow you to Continue reading

Certain HP laptops are found recording users’ keystrokes

Over two dozen HP laptop models have been secretly recording users’ keystrokes, possibly by mistake, according to a Swiss security firm.The keylogger is found within the PCs' audio driver software and has existed since at least Dec. 2015, the security firm Modzero said in a Thursday blog post.   The audio driver was designed to identify when a special key on the PC was used. But in reality, the software will capture all the keystrokes and write them in an unencrypted file located on the laptop.In other cases, the keystrokes will be passed to a Microsoft Windows debugging interface on the PC, and expose them to possible capture, Modzero said.      To read this article in full or to leave a comment, please click here
