Abstract
Considering the current industrial scenario it is
very important for the organization to have an
effective security protocol for their business
structure as it works with large set of data. The
leakage of those data may cause a significant
issues related to the service and reputation of
the organizational services. Followed by the
above aspects the application of VPN in the
organizational structure plays an important
role as it offers effective security service to the
organization. However, studies has proven that
there are several benefits of the application of
VPN, it has been also observed that there is
still some limitations present in the operations
of VPN which has been described in this
article. Thus, in order to effective analyse the
threat factors of the application VPN this
paper has fundamentally focused on the
drawbacks of VPN.
Introduction
Followed by the information security
aspect of the organizational data, it is highly
essential to provide the higher protection to the
organizational transaction as well as it is also
essential to provide effective solutions to have
a feature of data recovery in the organizational
field. The fundamental purpose of this paper is
to provide a thorough investigation on the
services of VPN as well as it will also analyse
the limitations present in the operations of
VPN while working in an organizational
structure. Followed by the above investigation
this study will also consist a brief investigation
on the mitigation process of the VPN threat
issues. Along with that the paper will also
cover a detail analysis on how other alternative
technologies can be utilized in order to
mitigate the problems caused by the
application of VPN. Lastly, it will conclude
with explaining how the application of the
suggested technologies are better than the
application of VPN.
Literature Review
According several studies it has been
observed that the implementation of the VPN
in the field of organization offers significant
facilities which helps the organization to
invoke their services as well as it helps to
protect the organizational information from
external threats. VPN stands for Virtual
Private Network which offers the organization
to work with an organizational authorized
network which allows the user to effectively
transact the information within the
organization of publically. The fundamental
purpose of this method is to provide protection
to the organization network as after utilizing
this method the users of the targeted network
will be able to only access the resources which
are connected with the organizational network
with proper authentication. In order to
maintain the security in the private network
this method has offered the authentication
process by certificates and passwords along
with the utilization of layered tunnelling
protocol has a significant role towards its
success. However, the implementation of VPN
has provided several advantages related to the
organizational services, various limitations has
been noticed in the working of VPN. From a
thorough analysis on the operations and
functionalities of VPN it has been determined
that there is a significant issue related to the
privacy of the user data, work efficiency, cost
as well as the limitations related to the
adoption of VPN for several devices. Thus,
this paper has fundamentally focused to
determine limitation of the VPN application.

Main Body
Followed by the above aspects this
paper has continued with the investigation
with the operation of the VPN. The thorough
investigation has stated that the application of
Virtual Private Network carries several
limitation related to the privacy issues of the
user information as well as the customer
investigation. It stands to represent the
problem which stated that since, the
organization which utilizes the VPN for the
organization operation it has been observed
that the organizational information as well as

2VPN
the customer information are handled by the
third party as well as the possibility of the
aspect of monitoring and analysis of the user
information also cannot be avoided. Followed
by the above aspects it also has the problem
related to the scalability of the Virtual Private
Network (VPN). The reason behind this
problem is that while the organization needs to
expand the services of the network it demands
a huge amount of money. Thus it can be stated
that the application of VPN in any large
organization costs high. Along with that the
issues related to the bandwidth of the VPN
also cannot be ignored as it restrict the
organization to limit their user as the more
user it take, less bandwidth the user will get.
However, while the organization has tried to
expand their bandwidth it has been observed
that it costs high. Followed by this analysis
can be stated that the application of limitations
which restricts to organization to expend their
services as well as it is highly expensive.
Considering the limitations of the VPN
services it is recommended to utilize the
Microsoft DirectAccess service. Microsoft
Direct Access is also provides remote access
facility which has been powered by the
Microsoft, which has especially designed for
the windows user. A thorough investigation of
the services of DirectAccess has stated that it
is more effective as well as more convenient
that the conventional Virtual Private Network
(VPN). While comparing the services of
conventional VPN and DirectAccess it has
been observed that the services of
DirectAccess offers the facility to initiate the
operations by the machine initiation whereas
the VPN process offers the client initiation
method. The machine initiation is more secure
than the client initiation process as the
machines are directly connected with the
management servers. Along with that it has
also stated that DirectAccess only provides the
services to the user if they are properly
certified by the organization. Apart from the
above aspects it has been also noticed that
rather than being a location based application
as the VPN, DirectAccess is not restricted to
any location which has a significant impact on
its performance. Along with the above aspects
the DirectAccess opt for information
encryption process by which there will be less
chance of data leakage as well as it offers to
restrict the analysis of the user information as
it violates the ethical issue of the
organizational services. Followed by the above
benefits the application of DirectAccess
reduce the overall organizational cost
compared to the conventional VPN. Hence, it
can be stated that the application of
DirectAccess in the organizational field can
reduce the organizational cost as well as it
invokes the work efficiency by expanding the
capacity of the organizational network
compared to the conventional Virtual Private
Network. Along with Microsoft DirectAccess,
SoftEther VPN also offers a sicure
communication protocol which fundamentally
based on the encryption procedure.

Conclusion
The above has effectively discussed
the functionalities of the conventional process
as well as it has effectively discussed the
limitations of the conventional virtual private
network. Followed by this analysis this paper
has also explains about the possible impact of
those limitation in the industrial field which
may cause a significant damage to the
organizational structure. Along with that this
study has effectively described the
functionalities of the other remote network
access techniques which has provided a
suggestion to utilize the Microsoft
DirectAccess in the organizational field in
order to mitigate the observed limitation.
Lastly, this paper has summarizes that how the
application of DirectAccess can help the
organizations to address their desired
requirement. Thus it can be concluded that
however there are several benefits present in
the utilization of VPN, this study has
effectively discussed the limitations of the
present VPN service as well as the study has
effectively discussed and recommended the
possible technology which can mitigate the
occurred problem.
Future Scope
However, this paper has effectively
discussed the functionalities of DirectAccess
and how the application DirectAccess can help
the organizations to mitigate their problems
related to the information privacy issue and
work efficiency it has been noticed that this
study must further proceed by investigating the
limitation of DirectAccess as well as the what
other technologies can be used to get more
feasible solution. Along with in future the
research must be held on how the limitation
present in the conventional VPN system can
be mitigated with new modification on the
working of VPN.
