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.

Open source software: The question of security

The logic is understandable - how can a software with source code that can easily be viewed, accessed and changed have even a modicum of security? opensource-security-question Open source software is safer than many believe. But with organizations around the globe deploying open source solutions in even some of the most mission-critical and security-sensitive environments, there is clearly something unaccounted for by that logic. According to a November 28 2013 Financial News article, some of the world's largest banks and exchanges, including Deutsche Bank and the New York Stock Exchange, have been active in open source projects and are operating their infrastructure on Linux, Apache and similar systems.

Beer and open source with Untappd

Greg Avola loves beer and coding. He loves beer so much that he made an app, Untappd, where users track their favorite brews. He loves coding so much that he wrote a book about mobile web development. According to him, if it weren't for open source software, his app—and the projects of many other developers—simply wouldn't exist. Read more in my interview with Greg about his open source journey, his favorite beer, and why check-in apps are still relevant. Read more

What is Docker, Really? Founder Solomon Hykes Explains

Docker has quickly become one of the most popular open source projects in cloud computing. With millions of Docker Engine downloads, hundreds of meetup groups in 40 countries and dozens upon dozens of companies announcing Docker integration, it's no wonder the less-than-two-year-old project ranked No. 2 overall behind OpenStack in Linux.com and The New Stack's top open cloud project survey. This meteoric rise is still puzzling, and somewhat problematic, however, for Docker, which is “just trying to keep up” with all of the attention and contributions it's receiving, said founder Solomon Hykes in his keynote at LinuxCon and CloudOpen on Thursday. Most people today who are aware of Docker don't necessarily understand how it works or even why it exists, he said, because they haven't actually used it. “Docker is very popular, it became popular very fast, and we're not really sure why,” Hykes said. “My personal theory … is that it was in the right place at the right time for a trend that's much bigger than Docker, and that is very important for all of us, that has to do with how applications are built.” Read more
