Understanding and operating Linux is important in IT especially in the Networking and web fields
as a majority of those systems are run with Linux. Web servers and host a majorly run with Linux.
Linux is vital to understand as there is note many people knowledgeable in it, however, it is a very
challenging system to learn and something I need to practice at.
Expanding upon Linux, I have a strong desire to learn it. While at my internship at Harris, one of the
people with whom I worked closely with was a master of Linux. It is a very intriguing operating
system that is highly flexible. It has the highest security as its code is unique because it is open
source, which allows for it to be programmed into any system. I have seen Linux based software
used to hack into a computer, duplicate hard drives, and emulate systems.

In windows almost every file require the use of extension in order for the system to function.
In Linux operating system they do not require the use of extension.
In Linux, the extensions are used only to make the user understand the type of file.
TYPE OF FILE: o In windows: hello.mp3 will be a mp3 file only and the extension is important to
be specified. o In Linux: hello.mp3 is considered as a normal file which can be used for texts, video

Open source is an approach to the design, development, and distribution of software, offering
practical accessibility to a software's source code. Some consider open source as one of various
possible design approaches, while others consider it a critical strategic element of their operations.
Before open source became widely adopted, developers and producers used a variety of phrases to
describe the concept; the term open source gained popularity with the rise of the Internet, which
provided access to diverse production models, communication paths, and interactive communities.

Using either GNOME or KDE, you can decide what interface you want and then add only the
features that fit your needs quickly and easily. If you are concerned with standardization, do not
worry. Linux sticks to the Unix standards. The Institute of Electrical and Electronics Engineers put
together the American National Standards Institute for Unix named the Portable Operating System
Interface for Computer Environments. It dictates a universal standard on how the Unix–based
systems are supposed to operate. (Asprey & Seruzzi, 2008) Linux has three major components–
the file structure, kernel, and environment. The file structure does what its name implies, puts files
in a specific order on any storage device. They are arranged in a hierarchy of directories and one or
more subdirectories all of which contain files. These directories are all interconnected. With the
exception of the standard directories that are set aside for system use, users have full control of the
files inside the directories. They can create and move directories, move files between directories,
share or restrict directories and files just by setting directory and file permissions. (Asprey &
Seruzzi, 2008) The kernel is really the heart of Linux. Its job is to operate all the programs and
manage the attached hardware devices. In order to put these kernels to work and operate any
computer operating system,

Iphone Xp : A New Research And Development Group Essay
Introduction My boss asked me to come up with a proposal to migrate Windows XP machines to
Linux. The company Linx LLC has a new research and development group – LSDG. All systems in
LSDG will be running Linux and will access and share resources with Linx LLC. The company has
around 500 client operating system desktop/laptops that runs Windows 7 and Windows XP. LSDG
needs to decide whether they're going to keep using both Windows XP and Windows 7 on their
desktops and laptops. LSDG must consider the following: costs, longevity of the machines, security,
and support. If LSDG decides to keep using Windows XP as their operating system, the company
will end up spending more to maintain and configure those machines. I would propose for Linx LLC
to have all their machines running Windows XP to update to Red Hate Enterprise Linux Operating
System. The last time for Windows XP support was back in 2014. "After 12 years, support for
Windows XP ended April 8, 2014. There will be no more security updates or technical support for
the Windows XP operating system." ("Support for Windows," n.d.) Running only Windows 7 variant
on some the machines makes it easier to have updates and especially security patches as well as
technical support when needed. Running Windows XP is a major security risk because like I said
Windows already stopped supplying patches and updates for this variant. As I suggested, Red Hat
Enterprise Linux Operating System will be the best choice to be used by LSDG. The

XP machines to a Red Hat Enterprise 5 Linux distribution to optimize performance and user
capability. As described perfectly by Karen Schwartz there are many reasons to switch "The reasons
are compelling: greater stability and reliability, lower cost, access to application source code, greater
security, and conformity with open standards" (Schwartz, 2004). The LSDG group will access and
share resources with HACKD, LLC.'s Active Directory domain such as authentication, DNS, DHCP
and file services to save on expenses and reduce the required footprint and administrative overhead.

Introduction
Generally, computer components are two–fold, namely hardware and software components. The
hardware requires an operating system (OS) to manage and coordinate its software resources as well
as provide services for computer application programs [4]. Application programs that run in a
computer require an OS. In essense, the OS acts as a central host that handles hardware operation
details [4]. All computers are run by an OS of some type. Some of the most popular OS versions in
the market are Linux, Windows and FreeBSD [1]. Linux is an open–source development and free
software whose source code can be freely used, redistributed and modified by third party OS
developers. The range of Windows Operating Systems are created by Microsoft Corporation. Unlike
Linux, Windows consists of proprietary closed sources [5]. FreeBSD is an advanced version of OS
and runs on modern desktops, servers and

The Pros And Cons Of Linux
In the beginning, Linus Torvalds, a young man who studied computer science at the University of
Helsinki, thought Unix–like academic operating system should be available for free and is an open
source software.
Hence, he decided to do a better operating system which is free of charge and is an open–source
software. The Linux kernel was first released in 1991, it is designed to be used with GNU software.
GNU developers eventually integrated their software into Linux to create an operating system.
Linux is everywhere so it is available in many forms to suit many needs where from consumer–
oriented systems for home use to distributions for use in specific industries. For instance, it is in our
smartphone, our Roku devices and even in our refrigerator. ... Show more content on

Linux is a software on a computer that enables applications and the computer operator to access any
devices on the computer to perform its desired functions. To put it simply, Linux is an operating
system that enable to manage the communication between software and hardware. The operating
system (OS) relays instructions from an application to, for example, the computer's processor. The
processor performs the instructed task, then send the results back to the application via the OS.
As we know, Linux is all free and easy to install. This zero cost of entry accompanied with an open
source license. Open source follows the following key of philosophies, for instance, the freedom to
study how the program works, the freedom of running a program, the freedom to redistribute copies
and also the freedom to distribute copies of the modified versions to the others.
Linux is said everywhere because it is powering roughly 94% of worldwide supercomputers, most
of the servers powering the Internet, the majority financial trades worldwide and a great number of
Android devices. It also appears in many different architectures, from mainframes to server to
desktop to mobile and on a wide variety of

Systems Administration And Network Services
1. Goal After two labs focusing purely on the Linux side of systems administration and network
services, this third lab puts Windows into the spotlight and how it deals with configuring services as
compared to the previous RHEL–based configurations. Many of the same tasks which were
completed using a RHEL 7 virtual machine in lab 2, such as setting up DHCP and DNS, are
repeated in this lab on a Windows 2012 Datacenter virtual machine. This is done not only to show
the differences in service administration, but also to indirectly teach students the steps as well as
precautions that need to be taken when integrating in different enterprise server operating system
families which very well could be running the same network services, such as in the case of this lab.
Instead of merely just installing the same services and letting the clients make decisions on what
data to receive from who, this lab also presents the challenge of making these two very different
operating systems work together when the time comes to configure the DNS server on the Windows
VM. A major point I took away from this is that while the Microsoft and ISC implementation of a
DNS server can be seen as widely different, the integration of the two is very smooth and easy due
to both of them still following the base rules of the DNS protocol as well as framework found in the
numerous RFC's which describe it. Active Directory, which is also installed on the server, was
review at this point from multiple different

Microsoft Baseline Security Analyzer And Windows Server 2012
1. Goal The main idea behind this lab was to relocate the DHCP server and master DNS server to a
fresh install of Windows Server 2012. This would allow control over most of the network with
Windows Server 2012 while maintaining a slave DNS server on the Red Hat Enterprise Linux 7
box. A basic install of Active Directory was also implemented, allowing a single client to connect to
the bestnet.local domain. Microsoft Baseline Security Analyzer was also implemented to determine
any outlying security risks associated with the Windows Server 2012. This lab took the knowledge
that I gained from in–class lectures and previous experiences, and allowed me to implement Active
Directory, DHCP, and DNS flawlessly on Windows Server 2012. It helped me to understand how
Active Directory and DNS are linked together to tie a domain together and populate that domain. By
playing around in Active Directory, I was able to gain valuable knowledge of how to implement
many features and roles directly related to an Active Directory installation.
2. Procedural and Informational Documentation All information pertaining to my virtual network
can be found at the address http://10.0.15.1/wiki or http://wiki.bestnet.local/wiki/ when inside my

Linux Based Systems Are Modular Unix Like Oss Build A...
Linux based systems are modular Unix–like OSs build a large part of its component from 1970s and
1980s UNIX principles. They apply a monolithic kernel, commonly identified as the Linux kernel to
execute process control, access to peripherals, file system management and networking tasks. Lonix
OS drivers are either directly integrated with the kernel or come in as additional modules created
while the system is awake. Independent developments with kernel interface improve the
functionality and performance. GNU user land association with Linux based systems provides
majority executions in the C library, a command–line interface (CLI) shell and the most common
tools of UNIX to carry out performance execution. A GUI is created on each implementation of the
X windows system. A recent development of the Linux OS is the use to Wayland display server
protocol replacing the X11. Ubuntu has made progressive developments of the Mir a diversion of
Wayland.

i. Boot loader– this is a program build to load the Linux kernel and input it in the computers main
memory. It starts its operations when the machine is switched on and after firmware initialization
execution. GNU GRUB, LILO, Coreboot, Gummiboot, and GNU GRUB are some common boot
loaders. ii. An init program: this is the very first operation initiated by the kernel and serves as the
background of the process. An init program causes the device to initiate any process running

by a German computer science student Michael Heerklot, who through interest in the discovery and
impact of Stuxnet exploit, decided to investigate Stuxnet attack, particularly the hack of the Natanz
uranium enrichment facility where the .LNK vulnerability in windows shell was exploited in 2010
[1]. He examined the .LNK vulnerability, which was presumably patched by Microsoft, to ... Show

The issue is that in Windows, icons are executed from modules (either executables or dynamic link–
libraries). In fact, .CPL files are actually DLLs. Because an attacker could define which executable
module would be loaded, an attacker could use the .LNK file to execute arbitrary code inside of the
Windows shell and do anything the current user could" [2]. The first patch released August in 2010,
Microsoft put in an explicit whitelist check with MS10–046. Once installed, it intended to ensure
that only approved .CPL files should have been used to load non–standard icons for links. This patch
failed and for more than four years, all windows files have been vulnerable to exactly the same
attack that stuxnet attackers used in initial exploit. In light of its recent rediscovery, it is unknown if
other groups discovered and exploited the vulnerability in the wild [2]. The section below explores
the section of code that was patched in the initial patch in 2010 and how the vulnerability remained
vulnerable. The definition of the function shown below is taken from a function called
CControlPanelFolder::GetUiObjectOf() in Shell32.dll. Shown in the diagram below is the first block
that was changed after zero day vulnerability was discovered. In the event below a whitelist check

Linux Versus Windows Xp : Pros And Cons
Comparison Report
Linux versus Windows XP: The Pros and Cons
This may be the perfect time to move over to Linux, since Windows XP was officially retired in
2014. Although we can continue using Windows XP, the two most important factors to consider are
1) there will no longer be security patches released by Microsoft; and 2) they are no longer
supporting this product.
Additionally, our older XP machines may not support newer Windows releases, especially 8.1,
because it needs significantly more power and storage. Also, some XP applications may not work on
newer versions of Windows. So to run 8.1 on older PCs, there will be a lot of configuring to do
which takes time and money. All machines will need at least 4 GB of ram.
That said, both Windows XP and Linux each have their advantages and disadvantages. To help
determine what technology option is best in the long run for the company (i.e., to keep Windows XP
or switch to Linux), the team recommends that you perform a careful analysis with respect to cost,
performance and risk to make the right technology decision. We don't envy your position–which is
challenging–one that can affect the company 's total cost of ownership (TCO) and return–on–
investment (ROI), positively or negatively.

Windows XP will continue to work, security is a major concern. Although security companies still
support XP, at some point we could find ourselves vulnerable. Without security patches, cyber

This necessitates the need for an ideal web server platform choice. Several operating system (OS)
platform alternatives are available to Tony's Chips. For instance, the company can choose to run the
new system on a Microsoft Windows Server OS platform. Some of the server platform applications
provided by Microsoft include Windows Server 2008 and 2012. These operating systems are
advantageous in that most online applications are available to the Microsoft Windows Server
platform. Additionally, expertise on Windows server OS is readily available. As a result,
implementation and maintenance operations for applications using this platform are complemented
by available personnel. However, Microsoft's licensing fees for new versions of the OS present an
economic obstacle to the adoption of the platform. In addition, the platform's security facilities are
not as reliable as those of alternative server platforms such as Linux and UNIX (MacDonald, 2009).
Linux offers a variety of server OS distributions. These include Red Hat, Ubuntu and CentOS. These
server platforms have the common advantage of being easily customizable, stable, secure and robust
(Tanenbaum, 2001). Cento possesses the best expertise support among Linux distros. This is
because of its long development cycle. CentOS, however, does not possess the enterprise level
operating abilities of Red Hat Linux. Of the currently available Linux distributions, Red Hat

Linux Operating System (graduate level CIS term paper)
1. What Is Linux?
Linux is an operating system that was initially created as a hobby by a young student, Linus
Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX
system, and decided to develop a system that exceeded the Minix standards. He began his work in
1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux
Kernel was released. The current full–featured version is 2.4 (released January 2001) and
development continues.
Linux is developed under the GNU General Public License and its source code is freely available to
everyone. This however, doesn't mean that Linux and its assorted distributions are free ––
companies and developers may charge money ... Show more content on Helpwriting.net ...
Process management creates processes, and implements multitasking by switching the active
process on the processor.
At the lowest level, the kernel contains a hardware device driver for each kind of hardware it
supports. Since the world is full of different kinds of hardware, the number of hardware device
drivers is large. There are often many otherwise similar pieces of hardware that differ in how they
are controlled by software. The similarities make it possible to have general classes of drivers that
support similar operations; each member of the class has the same interface to the rest of the kernel
but differs in what it needs to do to implement them. For example, all disk drivers look alike to the
rest of the kernel, i.e., they all have operations like `initialize the drive', `read sector N', and `write
sector N'.
Some software services provided by the kernel itself have similar properties, and can therefore be
abstracted into classes. For example, the various network protocols have been abstracted into one
programming interface, the BSD socket library. Another example is the virtual filesystem (VFS)
layer that abstracts the filesystem operations away from their implementation. Each filesystem type
provides an implementation of each filesystem operation. When some entity tries to use a
filesystem, the request goes via the VFS, which routes the request to the proper filesystem driver.

We have to change some hardware parts for proper users of the Linux operating system. One issue
that is slowly or gradually getting to be non–existent is hardware support. Quite a while back, on the
off chance that you needed to install Linux on a system, you needed to make sure you hand–picked
all of hardware or your establishment would not work 100%. I can remember or recall, in 1997–ish,
trying to make intellect of why I cannot get Red Hat Linux or Caldera Linux to understand my
modem. After plentiful of looking around, I discovered I was the content owner of a Winmodem. So
I wanted to go out and purchase a US Robotics outside modem because that was the one modem I
knew would work. That is less the case now. You can take a PC (or tablet) and in all possibility get
one or more Linux distributions to install and work about 100 % (100 percent). At any rate, there are
still a few individual cases. For example, suspend/sleep remains an issue with many portable PCs,
despite the fact that it has come a long way. We have to change the hardware requirements current t

the master DNS server with the Linux DNS server that was built in the last lab to be the slave. This
means that the Linux had to be configured to be the slave and when the master (windows) was set
up it would need the IP address or the hostname of the slave server (Linux). In order to configure the

Windows Active Directory is a central hub where a system administrator can change anything about
a users role in the organization and access on the network in a very short time unlike Linux. Because
SELinux is host based that means each change to a user or group means going in and configuring
them one at a time by hand while Active Directory GUI is much simpler to use when configuring.
Another benefit to active directory is the ability to authenticate. Authenticating prevents a user
without the proper rights to access something that they don't nee to edit or view. Once authenticated
a user has access to all internal Microsoft services and features that the policy allows for. I feel that
SELinux and OpenLdap if better for network management in the sense that it is very flexible and
can better manage the network. The only downside to this is it is much harder to set up and
configure. OpenLdap also has issues working with and connecting to windows devices on the
network. It is very rare in an organization to only see Linux with no Microsoft servers or clients.
Even though OpenLdap has the potential to be better at managing because of its flexibility a system
administrator would be more inclined to use active directory because of its ease and compatibility

Not only that, but users can even fix problems themselves. Microsoft may tout its large team of paid

Secure Than Windows, para. 13).
Administration
Riordan Manufacturing Corporation, (Apollo Group, 2004), is a hybrid computing environment
employing MS Windows, (Microsoft Corporation, 2011), e–mail and file servers along–side UNIX
Enterprise Resource Program (ERP) and a HP–UX, (Hewlett Packard Development Company,
2011), UNIX Manufacturing Resource Program (MRP). Effective administrative support of both
operating systems requires two information technology groups, one specializing in MS Windows
platforms and one specializing in UNIX platforms. Requiring two IT groups and two unique server
platforms doubles the administrative management and equipment costs in the enterprise.
Standardizing server hardware and software to one type will significantly reduce costs and increase
Riordan Manufacturing's return on its investment. One server operating system platform can support
all of the workstation's applications with the exception of MS Windows Exchange, (Microsoft
Corporation, 2011), e–mail application.
To reduce personnel costs it is recommend merging the two server platforms (operating systems) to
one where it is possible. HP–UX,

4.3 Task: File Permissions, Etc
1. Find and report all files with peculiar permissions. Examples: no permissions given ––– ––– –––,
executable but not readable, readable for group and others but not the owner, unsearchable
directories, etc.
To view file permissions, I used ls –la (–– removed HTML ––) command. For instance, to display
all the files of the /root directory, I typed ls –la /root. (see figure 4). The –a option would display the
hidden files which are typically the system files. Figure 4: viewing file permissions
The log.txt has no read, write, execute permissions.
2. Files and directories whose names begin with a dot are unlisted by ls unless –a flag is used. Find
and report all such files and directories whose size is larger than 10 MB.
4.4 Task: Check for Weak Logins
1. No password shoul be breakable within an hour. List the names and plain text passwords of such
users. Assume you are root.
2. Should root be allowed to login? Ubuntu/ Debian do not assign a passwd to root. Discuss the
pro/cons of this choice.
The advantages of not having root password is that the users can easily swich to root without
signing in with a password. This gives a flexibility of running certain scripts and installing
programs.

However, not assigning a password to root would be disadvantageous in terms of security. Any user
in the group would be able to

It is an implementation of a mandatory access control mechanism in the kernel of Linux. SELinux is
an access control implementation on the Linux kernel. The SELinux provides many kinds of data

According to NSA Security Enhanced Team, "Security Enhanced Linux is a set of patches to the
Linux kernel and some utilities to incorporate strong, flexible mandatory access control (MAC)
architecture into the major subsystem of the kernel." SELinux provides administrator more control
over access control.
SERVER:
The most important thing about Linux operating system is its server. Windows operating system was
initially designed for single user and in 2003 they made their first server operating system windows
NT 3.1 for multi users. However the Linux server is more stable, secure and cost effective as
compared to the Windows server. The windows server software, Windows Server 2008 standard in
United states costs about $999 and also five CALs(Client Access Licenses). Linux on the other hand
is completely free, licensed under GNU deneral Public License which allows free distribution of

Windows Server Business Plan
I propose that our company consider implementing Linux for our servers and workstations. There
are many excellent reasons to employ Linux as the operating system of choice for our company:
Linux is 'tried and true'; is used by many large companies, such as Google©, Amazon©,
Facebook©, and many of the cloud service providers; is less expensive; more reliable and stable;
has extensive free community support; uses memory and CPU resources more efficiently; is
reasonably easy and quick to install; and is much less vulnerable to viruses and malware than the
Microsoft Windows© operating system. Linux can be used on almost any type or brand of computer
or server, including older models. I will demonstrate that Linux is a viable and less expensive
alternative to Windows and will perform well in our server and workstation environments.
Server Environment
Hardware Considerations
Existing hardware. Our existing hardware can be used for the new Linux OS. This will require
reformatting existing hard drives and installing the Linux OS, which is much easier than
reformatting and installing Windows OS. Our older servers will still be viable for some time to
come because Linux uses less disk space and memory. It also uses less resources, so it won't slow
down the devices or the network like other Enterprise OS can.
Vendor specific hardware. If we wish to purchase vendor–specific hardware for one of the new
Linux distributions, there are several options: System76; Dell; HP; IBM;

Microsoft's internet information services (IIS) is one such solution. This webs server is designed to
run on Windows server platforms. Consequently, it integrates well with Microsoft's online
applications. It features an intuitive graphical user interface that simplifies its installation and use.
However, the costs of installing new versions of this web server are high. In addition, its restriction
to the Microsoft server OS platform inhibits system flexibility. An alternative to IIS is the Apache
web server. This is an open sourced application that can be implemented on a wide variety of
operating system platforms. Apache's integration of a pearl and PHP engine facilitates easy
integration with the application programming interface (Gunther, 2006). In addition, this web server
is available for free. This makes it a cost effective alternative. Further, Apache's event–driven
architecture enables it to perform ideally even under heavy loads. However, Apache usage involves
a relatively strenuous learning curve. The software's complexity may present an obstacle to its use
by new users. Another web server that can be adopted for use in this project is Nginx. This server is
easy to use as well as stable. It is also based on an event driven architecture. This architecture makes

MS Windows vs. Unix/Linux
The Microsoft and Linux operating systems have been long considered to be in a competition to be
the best operating systems on the market. This paper will compare and contrast these operating
systems to help the consumer decide which is right for his or her environment. Such subjects as;
cost, market share, hardware requirements, file processing, programming capabilities, availability if
application software, networking, and user interface will be examined.
Cost
The cost difference between running a Linux desktop / server compared to a Microsoft desktop /
server is overwhelming. ... Show more content on Helpwriting.net ...
Finally, marketing is a big "reason" why Microsoft still holds a large place in the desktop market
share. Microsoft is constantly keeping their products in the public eye view, where Linux does not,
causing people to know of Microsoft desktops but not so much about Linux desktops. With that said,
while Microsoft does hold a dominate place in the desktop world, the same is not so true in the
server world.
In the server marketplace, Microsoft is losing ground quickly to the Linux Server. Linux has been
gaining ground in the server world for several reasons including; cost, ease of use, and
dependability. The cost of the Linux server is much lower than that of the Microsoft server as we
examined earlier. This cost difference is opening up IT departments to the ideal of using Linux over
Microsoft, which in return is helping Linux gain server market share. Next, because Linux is
becoming easier to administrate, that too is moving IT departments to convert. In the past, Linux
was all "command prompt" oriented, today GUIs and such have been developed to help the novice

user with system administration. Finally, dependability is probably the biggest reason Linux is
gaining server market share. Perhaps the best way to explain Linux dependability is to explain that
Linux does not need to be rebooted once a week. But in
