Importance of Network Security in Healthcare Networks

This presentation discusses the importance of network security in healthcare networks and how it can be beneficial for the healthcare sector. It covers topics such as healthcare network architecture, cloud computing, wireless sensor network, and security issues in healthcare networks. The presentation also provides recommendations for implementing robust security measures to protect the data of patients.

HEALTHCARE NETWORKS

INTRODUCTION
 Network Technology Has Spread To Various Sector Of The Society
 Majorly Used In The Sectors Of Healthcare, Education, Finance,
And Gaming
 Use Of Network Technology Can Be Beneficial For The Healthcare
Sector As It Can Be Used To Provide Better Services
 Useful To Maintain The Security Of A Healthcare Organisation
 Implementation Of Iot And Ai In The Systems Of A Healthcare
Organisation Has Made The Functions Of The Organisation More
Swift And Efficient [1]

HEALTHCARE NETWORK ARCHITECTURE
• network of a healthcare organisation commonly
consists of switches, firewalls, servers, and
routers
• exchange of information among various
organisation is carried out using these devices
• Firewall: The firewall in a system is a network
security measure that is used for monitoring
and controlling all the outgoing and incoming
network traffic
• Servers: In the sector of networking, a server is
the computer program that offers functionality
for several programs or clients
• Routers: The implementation of routers in a
healthcare organisation is essential for
effective monitoring of the movement of
packets in the network
• Switches: A switch in a LAN connection of
Ethernet base is the device that monitors the
incoming packets or frames of TCP/IP data [2]

DEVELOPMENT OF CLOUD
COMPUTING IN HEALTH SECTOR
 Cloud computing: The problems faced by the healthcare network such
as huge IT costs, scalability, increased processing power, and the
demand of interoperability
 current health technology is inefficient in addressing these challenges.
 opportunity of cloud computing that has the ability of flexibility, multi-
tenancy, and metered delivery makes the technology ideal for
implementation in the healthcare organisations
 Cloud computing is the innovative method of delivering the required
resources and services
 cloud architecture in the network of a healthcare organisation can be
divided into two segments which are front end and the back end [3]

DEVELOPMENT OF WIRELESS SENSOR
NETWORK FOR HEALTH SECTOR
 IN THE MONITORING SYSTEM OF A HOSPITAL, IT IS ESSENTIAL
TO MONITOR THE PHYSIOLOGICAL PARAMETERS OF THE
PATIENTS IN REAL TIME
 MOST COMMON SYSTEM THAT ARE IMPLEMENTED IN THE
HOSPITALS FOR MONITORING THE HEALTH OF PATIENTS ARE
SENSORS
 WIRELESS SENSORS GATHERS ALL THE DATA OF THE BODY OF
PATIENT USING A COORDINATOR NODE THAT IS ATTACHED IN
THE BODY
 DATA IS SENT TO THE BASE STATION
 SENSORS THAT ARE ATTACHED IN THE BODY OF THE PATIENTS
FORMS A WBSN (WIRELESS BODY SENSOR NETWORK)
 THE DOCTORS ARE ABLE TO MONITOR THE BLOOD PRESSURE
AND HEART RATE OF THE PATIENTS CONSTANTLY

IMPORTANCE OF NETWORK SECURITY
 It is becoming essential to protect the aspect of data
and online information as the reliability on the
technology is increasing gradually
 With the growth of internet and computer networks, it
is important for the organisations to maintain the
integrity of data stored in the systems of the
organisations
 data that is stored in the healthcare organisations
consists of patients medical records and the
confidential details of the patients
 security of network is major consideration while
working on the LAN, internet, or any other network
 implementation of a robust network security provides
security to the data of the patients and prevents the
data from getting in possession of any unauthorised
user

SOME MORE IMPORTANCE OF NETWORK
SECURITY
 need of network security is essential in protecting the
systems from any harmful software
 security of shared data is ensured with proper
implementation of network security
 security for any network provides the necessary security
measures to the data by disintegrating the data in small
packets
 storing in various platforms by encrypting the information
and prevent the complete from falling in the possession
of any malicious user at the time of cyber-attack
 threat of huge incoming traffic when a system is
connected to the internet creates problems of stability
that can lead to several vulnerabilities within the system

SECURITY ISSUES IN HEALTHCARE NETWORKS
 Data loss: This is the threat of loss of valuable data or information due to errors
of humans, viruses, malware or power failure in the systems
 the main reason for data loss are theft of the systems, accidental deletion, or
rewriting the files, or sudden damage of hard disk
 Threat of security breaches: Security breaches can result in loss of data and
valuable equipments in the possession of malicious users
 data stored in the network of the healthcare organisation can be accessed by
individuals with no proper authorisation
 Malicious attacks: The attack that are carried out with the help of any malware
such as virus or worms can damage the network of an organisation resulting in
data loss

RECOMMENDATIONS
 after the analysis of the above mentioned threats, it is recommended
to place robust security measures in the network of the healthcare
organisation to protect the data
 the implementation of firewall can prevent the network from getting
hacked by any malicious user with intent of placing a virus in the
network and procure the data
 firewall allows access to the users with proper authorisation and
blocks the access of any individual outside the organisation [4]
