Demystifying Security Enhanced Linux

Filed under
Linux

In this paper I will try to explain the philosophy behind the Security Enhanced Linux (SE Linux). I will however try to explain the concept with an example but to keep the length readable I will restrain myself to go into much of implementation details for e.g. commands and similar stuff.

This flavor of linux has strong Mandatory Access control Built into the kernel where by the process and objects such as files are classified based on the confidentiality and integrity requirement, hence the affect of a security breach is reduced to minimal.

It is to be noted that this doesnot mean that SE Linux was designed to correct flaws which are present in the Linux rather it's an attempt to use MAC (in contrast to DAC used by traditional Linux Systems) to make a system which will mitigate the affects of security policy breaches to a minimum, by the help of policies which specify the security requirements of a system.

Women In Tech: Jane Silber, CEO Of Canonical

When I sat down to interview Jane Silber, CEO of Canonical, I don’t think it was lost on either of us that our ability to chat freely even though I was in my office in the middle of the U.S. and she was in her office in London, England had everything to do with cloud computing, an area in which her company does brisk business. Silber has been running Canonical (maker of Ubuntu, among a great many other software products) in one form or another for well over a decade at this point, first as COO and now CEO. She answers questions thoughtfully, with carefully chosen words; even though I’m sure I’m not the first journalist to ask her some of the below questions (maybe not even the first one this week), she had no canned responses, and she never veered off course to discuss her own agenda. There were no preset talking points; simply, I asked questions, and she answered them. Read more

In a Quiet Market for PCs, Chromebooks are Marching Steadily Forward

It's no secret that Chrome OS has not been the same striking success for Google that the Android OS has been. And yet, Chromebooks--portable computers running the platform--have not only found their niche, but they are also introducing a new generation to cloud computing. Chromebooks are firmly entrenched in the education market, where many young users have become used to the convention of storing apps and data in the cloud. Now, according to new research from Gartner, Chromebooks are ready to hit new milestones. Analysts there report that Chromebook shipment growth will be in the double digits this year. At the same time, though, Chromebooks have not become fixtures in the enterprise, replacing Windows PCs. Read more
