...IT302 Linux System Administration Research Assignment 1 SELinux or Security Enhanced Linux uses an architecture that separates enforcement from access policy decisions. With this architecture different types of policies can be implemented, including Role-Based Access Control (RBAC), Type Enforcement (TE), and Multi-Level Security (MLS). The module assigns security labels to each subject or object. It uses a security class to determine the kinds of relationship a pair of labels might have. The triplet consisting of a pair of labels and a class are then sent to a policy server to determine if access is allowed. The security labels are assigned dynamic integer security ID's (SID's); the reply from the policy server is cached in an 'access vector cache' for performance reasons. SELinux was developed in coordination with the open source community and the National Security Agency (NSA) to provide the highest level of security for the Linux operating system. Linux V-Server – The three basic elements of the VServer are: * The security context. A process in one security context cannot see processes in other security contexts, neither with the 'ps' command, nor with 'cat /proc' nor in any other way. As side-effect, this means that a process in one context cannot kill processes in other contexts. * Capabilities. The existing Linux kernel provides a wide variety of capabilities which can be taken away from processes. These include the ability to change network addresses...

He has resided in Portland, Oregon for more than ten years with his beautiful wife and two children, and currently works for Novell in the SUSE Labs division as a full time employee on the Linux Driver Project. He is considered to be an authority and “rock star” in his field, and is the co-author of "Linux Device Drivers, 3rd Edition" and sole author of the book entitled, "Linux Kernel in a Nutshell" (Rf.2). He used to be a contributing editor for Linux Journal, and began building the Linux kernel in 1996, and wrote the programs for the Linux kernel drivers in 1999. He is the current maintainer of the USB, PCI, driver core and sysfs subsystems in the kernel source tree, the staging subsystem, USB, driver core, debugfs, kref, kobject, and the sysfs kernel subsystems. Another one of his co-responsibilities is maintaining the Linux kernel for the -stable branch with his colleague, Chris Wright (Rf.3). He is also the maintainer of the linux-hotplug , and created and maintains the Linux Device Driver Kit. He also contributes articles to LWN.net, the news computing site, and in 2006, he released a CD image of material to introduce a programmer to working on Linux device driver development.

...Running Head: Research Assignment | Research Assignment | Linux Admin Class | | In 2006 Microsoft posted a high level summary of 235 patents that were allegedly violated by Free and Open Source Software (FOSS). These complaints included 42 violations from the Linux Kernel, 65 from the Linux GUI, 45 from the FOSS Open Source Suite, and 15 dealing with FOSS email programs (Microsoft's Smith and Gutierrez, 2007). Since this issue in 2006, FOSS has prospered beyond belief. Not only has FOSS survived, but it has grown enormously. Also in 2006, Microsoft signed a deal with Novell, agreeing that neither would sue the other (Upfold, 2006). Instead of fighting the FOSS business model Microsoft chose to instead join them with Novell's SuSE Linux model. Novell and Microsoft worked together in an attempt to collaborate with both open and closed source software. Their main competitor was Red Hat, who also was working on their own Linux system. Even more recently, Novell sold 882 patents to CPTN Holdings LLC in 2011. Upon the transaction, CPTN would dissolve itself. The patents were split up and purchased by Apple (25%), EMC (25%), Oracle (25%), and Novell's parent company Attachmate (25%). Another agreement of the deal allowed all companies involved to be free of any suits stemming from all 882 patents (Fosspatents blog, 2011). Microsoft was not negatively affected by the deal as they would essentially co-own the 25% share of patents Attachmate would recieve, as their...

What did Richard Stallman mean when he stated that GNU was a free operating system? What Richard Stallman meant by stating that GNU was a free operating system is that it was a free software that users had the freedom to distribute and change the product. 2. Describe the relationship between Linux and the GNU Project. The way that Linux and the GNU Project are related by them both being free software based. Also the GNU operating system today uses complete Linux binary compatibility. 3. List and describe in detail four advantages of Linux. The four advantages of Linux include: a) Affordability, Linux has open source software,meaning that there are no license fees. b) Portability, Linux is a generic operating system that can run on different types of operating systems from different companies. c) Security because it is logical based and everything is file based. d) Multiple users, it can run multiple tasks with many different users at the same time. 4. List three examples of different hardware platforms onto which Linux has been ported. Some examples of different hardware platforms that Linux was ported are Compaq's Alpha-based machines, MIPS-based machines, and Motorola's 68K- based machines. 5.

...Research Assignment 1 IT 302 Linux System Administration January 21, 2013 The purpose of this paper is to secure UNIX/Linux operating systems from unscrupulous people. It shall be focused on SELinux, chroot jail, and iptables. Each of the three focus areas will be detailed, with specific interest in the following. What organization is behind it and reason entity is involved. How each technology changes the operating system to enforce security, and if the security measure can be easily bypassed. And finally, describe the types of threats each of the technologies is designed to eliminate. Since no two UNIX-based operating system builds are exactly alike, it is important to note that each build may have its own inherent security flaws. SELinux was developed by The United States National Security Agency (NSA). The first version was made available to the open source development community under the GNU GPL on December 22, 2000. The software merged into the mainline Linux kernel 2.6.0-test3, released on 8 August 2003. Other significant contributors include Network Associates, Red Hat, Secure Computing Corporation, Tresys Technology, and Trusted Computer Solutions. Experimental ports of the FLASK/TE implementation have been made available via the TrustedBSD Project for the FreeBSD and Darwin operating systems. The reason NSA is involved in this project is because this organization is responsible for carrying out the research and advanced development of technologies...
