1. Introduction
Information is one most important part for
any organization and business industry and
it is observed that the security issue of
computer networks is growing very fast.
Healthcare is a big platform and it uses
wireless technologies to communicate with
their patients [1]. The main aim of this
paper is to describe the concept of networks
devices and architecture of healthcare
network. Any health care system collect a
large amount of data and it is not possible to
control and monitor complete information
of any patient for which many hospitals and
medicals adopt internet of thing which can
control electronic medical records. This
report is explaining the significance of
computer network and devices in the field
of healthcare and potential threats and
challenges faced by the network and
wireless technologies. In many healthcare
systems security is controlled by the
firewall and robust technique because they
reduce unauthenticated users and traffic
signals from computer [2]. This report is
divided into three parts literature review,
potential threats of healthcare network and
mitigation methods.
2. Literature review on networks of
healthcare
A healthcare information system is defined
as a process which can capture, store, and
control information of any patient and
nurses. They use wireless sensor networks
and local area networks to interconnect two
or more peripheral devices at a time. LAN is
used to enable the use of internal
information technology solution and it
provides communication between various
networks [3]. The architecture of healthcare
network is defined as physical properties of
any network that develop communication
system between patients and hospitals and
also implement various kinds of medical
processes. Wireless technologies change the
way of communication and it also improves
electronic medical records and treatment
systems [4]. Any healthcare network
consists of different types of networks
devices and components, for example,
routers, hubs, switches, bridges, servers,
and firewall [5].
Router
It is defined as a computer network which is
used to transfer data packets from one
location to another with the help of
connecting wires. The main function of this
device is that it passes data sets from the
computer device to the receiver circuit. One
router is connected from two or more
communication networks with the help of
data lines and when any data packet comes
in one of data link then it reads al
information and identifies unwanted signals
[5].
Hubs
A network hub is defined as a process which
is used to interconnect two or more
computer networks hosts. It is also used to
transfer data or information from one
location to another [6]. The information is
moved in terms of bundles on a PC arrange.
So when a host sends an information bundle
to a system center point, the centre point
duplicates the information parcel to the
majority of its ports associated with. Like
this, every one of the ports thinks about the
information and the port for whom the
parcel is expected, claims the bundle.
Network switch
It also works at the layer of local area
network and it is an advanced version of the
hub which can improve the performance of
communication system. There are many
healthcare and hospital which are using this
type of network devices because it can

identify unwanted signals move from
transmitter [6]. Therefore, for a small
network it hubs can be used but for large
computer network hubs are not suitable for
which this type of equipment can be
utilized. However, when any data packet is
received at any location then a filtration
process is used by which users can identify
any unauthorized signals.
Modem
It is the more interesting type of network
devices and it is very important for daily life
communication. Any computer system
produces signals in the form of binary data
and they are transferred from the
transmitter to the receiver with the help of
data links. The modem is a combination of
modulation and demodulation which is
used to improve the strength of an input
signal and demodulate the signal at the
receiver section [7].
Firewall
It is a kind of software which is used as a
protection process in healthcare networks
and it has the capability to reduce cyber-
attacks. There are many hackers they
produce botnet and flooding process by
which they can enter into personal servers
of healthcare and reduce this type of
problem information technology developed
software which is called as firewall [8].
When any user installs this software in their
computer and network devices then it
checks complete communication process
and if any unwanted traffic occurs into
network then it gives a notification on
desktop screen.
Server
The server is a kind of method which
provides a platform to share or receive any
file from users and it is generally used in a
computer system to deliver services. There
are mainly two types of computing servers
used in the healthcare network, for
example, a file server and print server [9].
Recent developments in healthcare
networks
There are many advanced technologies
adopted by health care networks such as
the internet of thing, wireless technologies,
and cloud-based services. They also provide
various serves to their patients and
customers like home automation, pocket
wallet, control their operation with the help
of smartphones. The ongoing advancement
in the medicinal services is the utilization of
square chain offices that aides in controlling
the information [9]. Web of therapeutic
things is the other improvement that helped
social insurance IT frameworks to speak
with one another [4]. A portion of the new
gadgets are accessible that aides in
following and sharing the information just
by being associated through Bluetooth or
Wi-Fi. These advancements help in
expanding the speed and offer remote
checking that builds responsibility of
patients by offering precise outcomes as
opposed to depending upon the manual
reports. The robotization additionally
diminishes human endeavours and builds
versatility by offering a total based on an
input circle that patient results can be
moved forward [10].
The importance of security in healthcare
networks
Security of data is very important for all the
social insurance arranges as it stores
classified and private data of a patient
which ought not to be spilled. On the off
chance that security rupture happens
patients may not feel secure in accepting
the consideration they require [11]. It is
imperative to keep up the security of the
considerable number of information in the
social insurance arrange as it might enable
access to unapproved client and
furthermore enable contenders to utilize
the information [2]. Thus, it is vital for the
social insurance experts to utilize shrewd

techniques to avert information ruptures
and keep patients data private [6].
3. Possible potential security issues in
Healthcare Networks
Denial of service attack
It is the very serious problem for any
computer networks because hackers attack
in user personal server by which they can
lose their data or information. In the year
2016, thousands of human computers are
hacked by attacks and it is identified that
they send spam emails and messages to
users [8]. Many healthcare systems also
received this type of unwanted signals in
their network and websites by which data
of any patient can be lost.
Ransomware attack
It is a significant issue that is looked at in
social insurance organize. It is a malware
that has caused major issues in the activities
and administrations. They utilize the touchy
data through some different doors. Getting
to the data through unapproved implies
causes security break [3]. They enter in the
framework and access eth records with no
learning. It refreshes the data with no notice
that may make false data about the patient.
Payoff product is one such assault that
keeps the organization to get to the records
of substantial clients [11]. This is an issue as
the approved client can't get to the data and
programmers utilize the scrambled data.
Phishing
The phishing assaults have expanded in the
ongoing occasions as it hazards the general
social insurance businesses. In the report, it
was discovered that email connections are
utilized to exchange medicinal services
records to patients. Subsequently, these
have expanded because of phishing as it
catches all the individual data alongside
login accreditations [4]. From the report, it
was discovered that national wellbeing data
sharing and investigation focus have
expanded the danger of deceitful messages.
Hence, these phishing assaults can be
expelled with the goal that every user use
proper configuration method and adopt
authentic servers with valid license key
[12].
4. Threat Mitigation technique
There are flowing steps given by
information and technologies by which any
healthcare network can avoid the issue of
ransom ware, DOS and other security
threats.
 For large network use number of
routers and hosts
 Use valid license key at the time of
configuration
 Reduce the use of a simple
password system
 Patients can use cloud-based
services
 Use proper intrusion systems and
biometric recognition process
 Limited login attempts
 Produce monthly report and guide
their employees to download
antivirus in their computers [12].
5. Conclusion
Security is a very dangerous problem for
any organization and community and it is
observed that users use their private
accounts and companies servers in another
computer by which they lose their privacy.
Any healthcare network uses various kinds
of peripheral devices to communicate with
patients and treatment equipment’s for
example, routers, switches, hubs, and
firewall which are described in this report.
If any healthcare uses limited login attempts
and adopts security plans by which they can
reduce various cyber-crimes. Consumers
should identify unwanted signals and fraud

emails and take action immediately because
hackers use the very complex algorithm due
to which they can encrypt their private
servers.
