Introduction
 Linux is a well known operating system
that has been build for Intel 386 Pentium
based for IBM PCs.
 Linux is mainly used for running powerful
set of compliers and programming tools
which is known to be free software
foundation.
 The biggest plus point of Linux is all
about focusing the overall ability which
can co-exit with other operating system.

Analysis on Linux-Based OS Security
 Operating system is known to be kernel of
the whole operating platform.
 Linux operating system is considered to be
Linux kernel.
 The present version which is being used is
2.6.22.6
 In the year 1991, Linux kernel was released
for the very first system.
 The biggest plus of Linux is ability to easily
co-exit with some of the other operating
system.

Analysis on Linux-Based OS Security
(Contd)
 Linux is known to be a leading operating
system that comprises of server and other kind
of system like main computers.
 It merely runs on coordinate system that
comes up with OS which is completely build
into microcode.
 It is merely inclusive of android OS, Linux
derivate and network routers and smart
watches.

Analysis on Linux-Based OS Security
(contd)
Both modules and sub-system aim to provide
operating system which is needed for proper
functioning.
 User Manner
 Types of Process
 Device Driver
 Management of Memory
 Networking

Reason to build of Selected System
architecture
 Linux is one of the popular version of
UNIX operating system. It is
completely open source in nature.
 It is completely free to use. Linux has
been designed by taking consideration
of UNIX compatibility.

Reason to build of Selected System
architecture (Cont.)
The architecture of Linux system mainly
comprises of list of layers like
 Hardware layer
 Kernel
 Shell
 Utilities

Reason to build of Selected System
architecture(Cont.)
There are large number of reasons for building the
selected system architecture like
 With the passage of time, operating system tend to
become much more complex in nature.
 This particular approach is mainly needed for
modular approach that group the following
components.
 In the given architecture, each of the layer can
communicate with the upper layer by making use of
interface which hide the implementation.

Quality attributes for System Architecture
that is for success
There are large number of quality approach which
is needed by software products like
Performance : It can be stated as a overall
response of time for performing the required
action in the given period of time. There are
mainly two different aspects to measure the
overall performance like latency and channel
capacity.
Interoperability : It is the another aspect of the
system which is responsible for operation and
complete transmission of data.
Usability : It is known to be as one of the attribute
by which the given function tend to work.

Quality attributes for System
architecture that is for success (cont.)
Reliability : It is a second attribute of the system that
is complete responsible for operating in the given
pre-defined condition.
Availability : It is known to be a part of reliability
that is completely expressed in ratio form between
total working time.
Security : It is known to be overall responsibility of
the system which can reduce the complete likelihood
or any incident of accident.

Quality attributes for System architecture that is
for success (Cont.)
Maintainability : This particular aspect can be considered
to as the overall changes in the system that is completely
related to needs of business. Maintainability can affect the
overall time which is needed for restoring the given system.
Modifiability : It merely tends to highlight the required
changes that is needed in the system. In this case, change
tends to affect only a single parameter.
Testability : This particular aspect highlight how well the
given system can perform.

Effect of Architecture and quality on the
overall success of system
 The overall architecture of system mainly
describes most of the major components along
with relationship between them. It is all about
analyzing with other aspects.
 The overall architecture and design of this
operating system is mainly inclusive of quality
attributes, design and lastly strategy.
 In any given software architecture, an abstraction
is given for proper management of complexity of
the system.

Effect of Architecture and quality on the
overall quality of system (cont.)
 It merely defines the required decision
about the given organization that is
completely related on the development of
software.
 In this each of the given decision mainly
tends to affect the quality, performance
and lastly overall success of the Linux
operating system.

Effect of Architecture and quality on the
overall success of system (cont.)
 Selection of proper elements along with their
interface that comprises of given system.
 Complete behavior for overall collaboration
in the given elements.
 Composition of structural and overall
elements of behavior elements in the given
system.
 Architectural design that is needed for overall
objectives of the business.

Steps taken to improve the Quality
attribute of the system
There are large number of steps which
should be taken for overall improvement of
quality of the system like
 Quality of Design
 Qualities for run-time
 Qualities of system
 Quality for non-run time

Steps taken to improve the Quality
attribute of the system (Cont.)
 Quality attributes is mainly needed for meeting the
overall need of the customers.
 A proper functionality of the system is provided in
much user friendly way.
 Each of the given attribute is mainly needed for
understanding the overall performance of the product.
 The given attributes are mainly needed for
understanding the quality assurance along with quality
control.

Steps taken to improve the Quality
attribute of the system (Cont.)
There are large number of design plan that highlights
the overall elements of the system more specifically
how they fit. It merely come up with following
objectives like
 Making and negotiating with overall need of the
system with list of parameter like marketing,
managing the personnel.
 Acting like a blueprint at the instance of
development stage.
 Providing a proper guide to detail design,
integration and testing.

Quality attributes that are affected
The quality attributes that are affected are
 Performance
 Interoperability
 Usability
 Reliability
 Availability
 Security
 Maintainability

Quality attributes that are affected (Cont.)
Other aspects are
 Modifiability
 Testability
 Scalability
 Reusability
 Supportability

Trade-off made
 In middleman, a proper marketplace is
provided for games that are provided and
sold.
 Some of them come up with off-platform
competitors. Other are lightened or
integrated without the need of iterative
platform.

Implication
There are mainly five implication of Linux operating
system like
 Linux is completely out of way
 User is not completely slave to terminal.
 Software installation is very easier.
 The updates are considered to that much hectic.
 The present community of Linux.

Comparison with other system
There are large number of difference between Linux
and Windows operating system
 Access
 Flavor or variety
 Licensing
 Command Line
 Run Level
 Usability : Linux is very much complicated to
Install.

Comparison with other system (Cont.)
In addition, there are many differences like
 Support : Linux provide much better
support for the given community.
 Updates : Linux user have full control on
the overall updates
 Security : Linux is much more secure in
comparison to Windows.

Conclusion
 Linux is an operating system who usage of
software on the system helps the application and
computer system operator for having an easy
access to various devices. Linux OS is considered
to be very much similar to operating system like
windows OS. The complete security in Linux
comes up with password authentication.
