Linux introduction ♦ Linux distributions ♦ Linux kernel What is a Linux distribution? ♦ it is a collection of applications, packages, management, and features ♦ ♦ ♦ ♦ that run on top of the Linux kernel. The kernel is what all distributions have in common (it is sometimes customized by the distribution maintainers) If they are all “Linux”, why are there so many different names, and which do I choose?” You may have heard names like Red Hat, Fedora, Debian, Ubuntu Distributions differ in several ways, and three of the most important are: ► ► ► Purpose Configuration and packaging Support model What’s a kernel? ♦ As you already know from the Operating Systems course ► the kernel is the core of all computer operating systems ► is usually the layer that allows the operating system to interact with the hardware in your computer ♦ The kernel contains software that allows you to make uniform use of ► hard disk drives, ► network cards, ► RAM, ► and other hardware components. ♦ In the Linux world, the kernel is based on code originally developed by Linux’s founder, Finnish developer Linus Torvalds. Back to distributions – Purpose, Configuration, Support ♦ Purpose ► Different distributions are often designed for different purposes and provide different user experiences. ► Some distributions are designed as servers, others as desktops, and some are designed to perform particular functions, for example, as embedded...

...Chapter 2 Installation Overview 1. A Net Boot CD is a way to install a new system from a hard disk or over a network. 2. Three considerations for planning an installation are; a. SELinux improves system security by implementing mandatory access control policies in the Fedora kernel b. Install a Graphical desktop environment (GUI) such as GNOME and/or KDE. c. Install additional software and services packages to fit the need of the user. 3. By default Fedora divides the disk into three partitions, including ‘/boot’ and Logical Volume Manager (LVM). 4. Manual partitioning the hard disk has its advantages, such as being able to isolate a filesystem for security or backup needs. 5. The / (root) partition is the main filesystem on the hard disk. Any new created directories will become part of the root filesystem unless a filesystem is created. 6. The swap partition is where Linux temporarily stores programs and data when it does not have enough RAM to hold all the information it is processing. 7. The /boot partition holds the hernel and other data the system needs when it boots. In order for the /boot partition to work properly it must be one of the first partitions on the disk. 8. The /var (variable) partition holds the bulk of system logs, package information, and accounting data. The /var/log partition is commonly used in a separate partition to isolate system logs from other files in the /var directory. 9. The /home partition is...

Include an overview of the major tasks accomplished in this lab and any difficulties you encountered in the completion of this lab assignment. Installing the Fedora 13 seemed easy enough but did take a long time when it came to the part of loading everything. I followed the lab instruction that helped me accomplished this which wasn’t too bad to follow. I did wish it had the explanation of each step like the other labs because it helped me understand what I’m doing and given the reason I never dealt with Linux before. The overview of the whole installation started with the “disc” and running it, then from the initial I was able to customize a few things (language, date and time, storage drive, own password, partition, software package, etc.). Luckily I did not encounter any problem that I was not able to install it but instead it went smooth. Something I did notice different was the appearance and where the taskbar was located.

...kernel of Linux, known as Linux version 0.0.1 Free software, as defined by the FSF (Free Software Foundation), is a "matter of liberty, not price." To qualify as free software by FSF standards, you must be able to: Run the program for any purpose you want to, rather than be restricted in what you can use it for. View the program's source code. Study the program's source code and modify it if you need to. Share the program with others. Improve the program and release those improvements so that others can use them. Red Hat Linux : One of the original Linux distribution. The commercial, nonfree version is Red Hat Enterprise Linux, which is aimed at big companies using Linux servers and desktops in a big way. (NJIT) Free version: Fedora Project. Debian GNU/Linux : A free software distribution. Popular for use on servers. However, Debian is not what many would consider a distribution for beginners, as it's not designed with ease of use in mind. SuSE Linux : SuSE was recently purchased by Novell. This distribution is primarily available for pay because it contains many commercial programs, although there's a stripped-down free version that you can download. Mandrake Linux : Mandrake is perhaps strongest on the desktop. Originally based off of Red Hat Linux. Gentoo Linux : Gentoo is a specialty distribution meant for programmers.

...shapes and sizes which is why operating systems such as Linux develop ways to keep your personal files safe from these unwarranted threats. Some of these measures include, but is not limited to; iptables, SELinux, chroot jail, TCP Wrappers, firewalls, PolicyKit, NX or No eXecute, PIE or Position Independent Executables, Netfilter, and the list goes on (“Fedora Projects” & Vepstas). When a user first approaches Linux it looks similar to what a windows operating system would resemble. With Linux a user has the ability to access every file within the operating system through the use of a terminal or command prompt. Through the use of Linux programming potential threats can gain access to you file system and everything housed within it. Linux is free software that comes with many great security features that any user or administrator greater access and control over the system. The choice can be a bit much for most, but we will discuss a few of these choices here. Security-Enhanced Linux also known as SELinux is a security program that was developed in partner by the National Security Agency or NSA and Red Hat Developers (“Fedora Project”). So what exactly is it that SELinux does? SELinux was designed so that the Administrator could enforce policies that will limit what a user or particular program...

...important types of Linux security technologies are Security Enhanced Linux (SELinux), chroot jail, and iptables. These security measures aide in the subversion of theft and malicious activity. We will discuss these items in depth to address who created them and for what reason. Along with how these technologies changed the operating system to enforce security, and the types of threats that these security systems are design to eliminate. Security Enhanced Linux was released in December of 2000 from the National Security Agency (NSA), under the GNU general public license. SELinux is not a Linux distribution; it is a set of kernel modifications and tools that can be added to a variety of Linux distributions. SELinux is currently a part of Fedora Core, and it is supported by Red Hat. Incarnations of SELinux packages are also available for Debian, SuSe, and Gentoo. Security-enhanced Linux is a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible Mandatory Access Control (MAC). MAC provides an enhanced process to enforce the separation of information based on confidentiality and integrity requirements, as well as the confinement of damage that can be caused by malicious or flawed applications. The previous security structure, discretionary access control (DAC), allowed threats of tampering and avoidance of security mechanisms, because DAC gives the user ownership of files and allows users the ability to make policy decisions and assign security...

...Linux Security Technologies SELinux (Security Enhanced Linux) is a mandatory access control in the Linux kernel that was originally developed by NSA (National Security Agency) with direct contributions provided by Red Hat Enterprise Linux (RHEL) via the Fedora Project. In the day and age of identity theft and attempted sabotage from terrorists against our country, it should be very apparent why an organization like NSA had such an interest in heading up development of a more secure way to better protect our nation’s computer systems. In a world so largely dependent on computer systems, inadequate security measures could lead to anything from having a single person’s financial information compromised to an electronic 9/11 against some of our country’s most secure federal computer networks. In the modern computer based society we live in, security is essential to protecting everything from personal desktops all the way up to the most secure federal databases. And many corporate and government level computers are based on the Linux kernel. SELinux has 3 states it can be in if on a system: Enabled, Disabled, and Permissive. Enforcing means SELinux security policy is active, Disabled means SELinux security policy is not active, and Permissive is a diagnostic state commonly used for troubleshooting. To better understand what improvements Mandatory Access Control (MAC) can provide for security, one needs to know about the standard Linux security provision called Discretionary...

...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...
