Five essential services provided by a secure system are Authentication, Authorization, Integrity, Privacy and Non–repudiation. So we can use security
measures like use a strong password, Protect confidential information, Make sure our operating system and virus protection are up–to–date, Use secure
and supported applications, Beware of suspicious e–mails, store confidential information only on HSU servers, backup our data and make sure we can
restore it, protect information in all its forms, learn to be security aware [1]. The security is provided to any kind of system by using three measures as
Software Security, Hardware Security and Database Security which conceptually shown as follows: Figure 1: System Security Framework
2.SOFTWARE SECURITY
Software security is an idea implemented to protect software against malicious attack and other hacker risks so that the software continues to function
correctly under such potential risks. Security is necessary to provide integrity, authentication and availability [2].
Basically there are two types of software's: System Software and Application Software. The security is provided by both kinds. The primary software
security is provided by the operating system. So we performed analysis on various categories of operating systems for security issues and techniques.

Twenty systems will initially be imaged for Linux and configured to run on the existing network environment. A testing group will be compiled from
departments across the organization to determine how the operating system meets user needs in various departments. After a ten day testing period,
any problems identified can be resolved as required to support a seamless transition. The phased migration can then be completed 50 systems at a time,
cycling the Linux systems in and the XP systems out. As the XP systems are collected, Linux will be installed on them to continue with the phased
concept. Diagram B displays how the systems will be tested, configured and distributed. Additional factors need to be taken into consideration for this

Samba specifically supports Linux access to print services for Windows alongside CUPS and file services as well as authentication through a daemon
called Winbind. Winbind, provides communication for Pluggable Authentication Modules (PAM) and Name Server Switch (NSS) on the Linux side
with Active Directory on a Domain Controller. It uses Kerberos and Lightweight Directory Access Protocol (LDAP) to authenticate and retrieve user
and group information. (Kirkpatrick, 2008) Printing capabilities from the Linux systems will be essential and will most likely be very similar to the
requirements with the user tasks in the current XP configuration. Since the print services are managed by Windows resources, meeting the printing
needs of the Linux users will be accomplished through SMB using Samba. The printers currently active on the network have been verified to work
with Linux systems, so once properly configured, Linux users will have no problem with their printing needs. The protocol for Samba is already
integrated into the Windows Server environment so configuring the settings on both the Linux and Windows sides is not a complicated process,
although it is an additional requirement that would not be required for a Windows client workstation. (Shinder, 2012) The information required to
configure Linux systems to print in the existing environment consist of the print server, printer share and appropriate Windows login password. A
script using smbclient shell will support the setup for printer configuration. File sharing in a structured environment is a useful feature that is common
in a Windows environment and provides ease of access based on permissions established for designated file shares. Fortunately, this capability is not
restricted with the integration of Linux. Samba is a versatile package that can serve as the solution for many areas to include file

5. Operating System Security Concerns : Os
Operating System Security Concerns
The OS in general lacks security and portability. The services on an OS are acutely vulnerable to malicious and random faults, as the OS are huge
and are prone to security and reliabilities gaps. Moreover, the modification of the state of an OS is extremely complex in nature. Additionally, changes
like cloning, encrypting, moving, or restoring are too challenging to accomplish. The OS provides the capabilities of event logging, however, this
ability has a few shortcomings, such as, the intruder can disable the logging mechanisms before the attack, and secondly, it is often extremely difficult
to find the critical information necessary to discern the attack and steps employed by the intruder to harm the OS, therefore, the overall recovery
process becomes problematic (Chen & Noble, 2001).
Furthermore, in the contemporary OS, the expectations of multi–tasking, time–sharing, and resource–sharing are abundant. The fundamental OS
contains the security features such as task control blocks, virtual memory spaces, and inter–process communication. The OS also contains restrictions
on operations and processes based on user identity and ownership level. However, the OS security lacks various integral considerations, for instance,
restrictions based on the trustworthiness and operations of the utilities, user roles, and the data integrity and sensitivity. Therefore, the OS can be
compromised effortlessly by an attacker by means of a security breach in

6. Object Oriented Programming
FREQUENTLY ASKED QUESTIONS (JAVA) IN INTERVIEWS 1)What is OOPs? Ans: Object oriented programming organizes a program around its
data,i.e.,objects and a set of well defined interfaces to that data.An object–oriented program can be characterized as data controlling access to code.
2)what is the difference between Procedural and OOPs? Ans: a) In procedural program, programming logic follows certain procedures and the
instructions are executed one after another. In OOPs program, unit of program is object, which is nothing but combination of data and code. b) In
procedural program,data is exposed to the whole program whereas in OOPs program,it is accessible with in the object and which in turn assures the
security of the code.... Show more content on Helpwriting.net ...
Ans: final : final keyword can be used for class, method and variables.A final class cannot be subclassed and it prevents other programmers from
subclassing a secure class to invoke insecure methods.A final method can' t be overriddenA final variable can't change from its initialized value.
finalize( ) : finalize( ) method is used just before an object is destroyed and can be called just prior to garbage collecollection finally : finally, a key
word used in exception handling, creates a block of code that will be executed after a try/catch block has completed and before the code following
the try/catch block. The finally block will execute whether or not an exception is thrown. For example, if a method opens a file upon exit, then you
will not want the code that closes the file to be bypassed by the exception–handling mechanism. This finally keyword is designed to address this
contingency. 15)What is UNICODE? Ans: Unicode is used for internal representation of characters and strings and it uses 16 bits to represent each
other. 16)What is Garbage Collection and how to call it explicitly? Ans: When an object is no longer referred to by any variable, java automatically
reclaims memory used by that object. This is known as garbage collection.System.gc() method may be used to call it explicitly. 17)What is finalize()
method ? Ans: finalize () method is used just before an object is destroyed and can be called just prior to

Cryptography
The practice and study in securing communication between parties in presence of potential adversaries. A cryptographic algorithm or cipher is a
mathematical function used in a plaintext in the encryption and decryption process. A cryptographic algorithm works in combination with akey
(number, word, or phrase) to encrypt the plaintext. The same plaintext also encrypts to differentcipher text with the use of different keys. The core of
modern cryptography is the construction and analyzation of protocols of various aspects in information security such as data integrity and
confidentiality, authentication, and non–repudiation.
Modern practice of cryptography involves cryptographic method.
First cryptographic method is the Symmetric–Key Algorithm also known as Secret key Cryptography. The symmetry of algorithm comes from both
parties involved sharing the same key for both data encryption and decryption. It works like a physical door where anyone who has the right locking
and unlocking uses a copy of the same key. Symmetric–key Algorithm works by taking the message and combining it with a shared key that inputs the
algorithm then outputs a ciphered message.
Two ways of symmetric–key algorithm encryption involve block ciphers and stream ciphers.
Stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In astream cipher
each plaintext digit is encrypted one at a time with the corresponding

Administration
Windows Server Advantages There are many administration advantages for Windows Servers. One aspect is domain operations which are an
important resource available on the network through Window Server. Making Window Server a domain controller adds security and the ability to add
local and group policies to the network (Garza, 2010). If Window Server is not promoted to the status of a domain controller, then it can run simple
network operations using peer–to–peer structures (Garza, 2010). These are workgroups, and they can only block or allow access but do not provide
control features for the network. The numbers of ... Show more content on Helpwriting.net ...
Disadvantages One of the biggest disadvantages is that it does not have a specific organization which updates and provides services, or software
tweaks in a regular manner as Windows does. Another disadvantage is that the lack of graphical user inters faces, or the absence of free tools and
software when compared to Windows (Host wisely, 2011).
Performance
Windows Server Advantages Windows server offers anywhere access with great flexibility, which allows a company to build, deploy, and manage
applications and websites on premises, in the cloud, or in hybrid environments using a consistent set of tools and framework Windows server also
offers frameworks, services, and tools to help increase scalability. (Microsoft, 2012). Disadvantages Windows servers are notorious for being
vulnerable to worms while there have been basically no worms affecting UNIX in the past ten years. Any server running on windows should really have
anti–virus software on it just like a desktop would. While window servers are unaffected by this they are just as susceptible to malicious and
mischievous hackers as window servers and therefore must still be patched UNIX Advantages There are many performance advantages for

A small business server handles under 50 users and an enterprise server 50 or more. Novell Netware, Windows NT, and other scalable server solutions
will handle various numbers of small business user loads. At a certain point a business will require an enterprise server product. This OS will be
capable of handling massive user traffic and provide a total solution: a comprehensive set of software tools that will allow a business to be run using
computers. An enterprise OS will be run on a minicomputer such as the HP9000 or a super–microcomputer with large data processing capacity like a
multi–processor Alpha Chip–based machine. Enterprise computing is a term describing a set of software tools with a network OS at its core.
Enterprise computing provides not only a place to store and share files but everything required for a business to gather and manipulate information
throughout the business as well as Internet access for customer support and business–to–business data flow. An enterprise computing product is
generally made up of the network OS and components that provide one or more of the following: file service, print service, Web page hosting,
Internet access/firewall, mail service, backup, and database, and/or SQL database services. A server is, as the name implies, a provider of computing
