Security Challenges in Healthcare Networks

Unit Title: Overview of Network Security
Assessment Title: Security Challenges in Emerging Networks
EXECUTIVE SUMMARY
The paper will be focusing on the security challenges of
the healthcare networks. The paper will be focusing on
the healthcare network architecture and the network
issues related to the architecture. The paper also
highlights the importance of the risk mitigation steps
which should be practiced by the healthcare industries to
ensure network security. The different types of threats
associated with the network security are discussed in this
paper which helps in understanding and evaluating the
risk mitigating strategies which are also discussed in the
later sections of the paper. The paper concludes with
effective risk mitigating strategies which help the readers
of this document to know about all the possible steps to
minimize the chances of having any network security
issues in the healthcare industry.

INTRODUCTION
The prime objective of this paper is to understand the
security issues of the private networks in both the private
and public sector industries. The different types of
securities issues of the network based applications and the
cloud based applications are highlighted in this paper. The
paper highlights the recent developments in the field of
science and technology considering the security aspects of
healthcare networks [12]. The importance of the security
measures is also discussed in this paper which helps the
readers to more about the changing nature of the risks.
Critical analysis of the security issues are the major
healthcare industry is the most essential feature of this
papers along with that the paper also discusses the
different types of threats. The three major threats of the
healthcare care industry which are malicious programs
such as the Wannacry ransomeware, threats coming from
inside the healthcare industry and the threats coming from
the different types of phishing emails are discussed
thoroughly in the paper [5]. All the associated issue
related to these major risks are also discussed in this paper
so that all the essential details related to the network
security in hospitals as considered. The risk mitigation
steps of one of the three discussed issues are stated in the
paper. The risk mitigation steps are proposed in such a
way that it maintains the growth and productivity from
both the point of view of the internal as well as the
external stakeholders of the hospital.
LITERATURE REVIEW:
HEALTHCARE NETWORK ARCHITECTURE
According to Patil, Harsh and Ravi (2014), the healthcare
network architecture is a very important aspect regarding
the healthcare care industry. The author stated that the
hospital authorities and patients access sensitive
information which is needed to be protected at any cost.
The authors of this paper highlighted the importance of
the security in the network architecture, they stated that it
is very important for the hospital authorities to
concentrate more on the architectural of those networks as
they are the most basic and fundamental units of the
networking system in the healthcare industries. According
to the author the developments in the field of advanced
computer applications has led to the growth of advanced
threats and vulnerabilities which can have a direct
negative impact on the outcome of the healthcare
industry.
According to the author all the components of the
networking architecture are vulnerable to the threats and
vulnerabilities so each of those components should be
frequently evaluated by dedicated teams which will be
enhancing the efficiency of those architecture. The writer
of this resource stated that each unit or block of the
network architecture should be critically examined so that
there is no security issues related to them. The author
focused on the importance of the analyzing different units
of the networking system such as the packets which are
transmitted from one point of a system to another point.
The security issues related to the routers can be
purposefully solved with the help of the risk mitigation
strategies which are stated in the later sections of the
paper. However, it was found that the main limitations of
this resource us that the author failed to showcase any
particular healthcare industry which is facing issues in
their network architecture.
As discussed by Baig et al. (2015), trafficking is one of
the most vital issues related to the server security in the
healthcare industries. These issues can have a direct
negative impact on the network architecture in healthcare
industry. The author of this paper focused on finding the
possible risks involved in the healthcare network
architecture and the author concluded that ARP spoofing
and Spanning Tree control attacks are the most significant
vulnerabilities associated with those networks. MAC
address flooding is the other types of network security
issues related to the healthcare network architecture.
