MN502 - Security Challenges and Solutions in Healthcare Networks

This report examines the architecture of a healthcare network, focusing on security challenges and potential solutions for a radiology system implementation. It highlights a three-layer client-server model employing secure sockets layer protocol for verification and suggests using public-key cryptography infrastructure (PKI) and certificates to enhance security. The system uses eToken devices for operator authentication and restricts access based on user roles. The report also addresses internal and external security threats, emphasizing the use of VPN tunnels and traffic sieves. Recent innovations like payer-provider analytics and competitor analysis are discussed alongside potential issues like cloud threats and encryption blind spots, recommending solutions such as traffic monitoring and selective decryption to maintain data privacy and compliance. The report concludes by emphasizing the importance of scalability, user-friendliness, and secure remote access in modern healthcare networks.

architecture
Consists of a three layer client-server style to be utilised during a hospital
system implementation for a radiology system. The server solves problems
with authorization, information security, verification, privacy and privacy of
entry. the tactic of verification is that the usage of secure sockets layer
protocol.
To verify quality of movable operators inside the setting of electronic
business and electronic health knowledge dealings, this report suggests
application of public-key cryptography infrastructure (PKI) and certificates.
This methodology makes considerations for functions, for integration of
knowledge} and progress among totally different medical systems so as to
determine an enterprise hospital info system plus has a plan style structure
exploitation digital link in hospital.

Computer client
 The operator’s communication through the verification coordination is
characterized through associate device that is eToken. This ensures user
transparency and flexibility permitting the doctor entry to any patient
record from any end-point at intervals the link.
 The user’s verification at intervals the operational structure is completed
through moving into the device personal identification number. Grounded
on the privileges of the operator’s structure unit the communication with
the records is restricted through the rank of the operator at intervals the
establishment. The system defines several clusters of operators:
management personnel, head of section, doctors plus nurses. Each of
those clusters square measure restricted to their department that is own
and on their position, they'll either correct or envision the info as of the
folder.

 The search outcomes shown among the range of the individual’s name, the operator
having the flexibility to decide on among viewing the individual’s details. The
individual details frame, corresponds to knowledge found on the uniform medical plan.
This knowledge comprises demographic information regarding the individual last
name, address plus citizenship. Common health records are shown: people,
sensitivities, and, for infants, the burden at delivery. This permits medical workforce to
rapidly verify individually. The essential region in the system is the individual past
record. It's shared into two sections. The primary demonstrates all the medical
appointments among the formerly selected timeframe. Associate ID and conjointly the
year it fully was created is introduced therefore on differentiate between the visits.
Every appointment relates to one of the individual’s health plans. Entirely the info is
shown among the subordinate panel. At the patient history window the user can
browse body knowledge love the date of entry, the workers taking care of the patient
plus identifies a bit like the liberation standing code

 Through the use of the Domain Regulator, we've a bent to ensured information
security amongst the system’s operators. But therefore on apply a completely safe
answer, the association amongst the patron plus additionally the computer server
ought to even have firm group action rules and strategies. As our network suggests,
the structure includes two entries that use packet sifting methods on information
effort. Often, the association amongst the assorted sites is formed through a free
network. There is in addition the chance of installing a private communication
strength, increasing the costs of the coordination, but providing occupied
management of the information movement

 Several factors are taken into the thought resembling doable integration with different
existing networks, measurability, user friendliness and remote and secure resource
access. Measurability is critical so as for the structure to adjust to any well-being
establishments. Because the system is adopted, the growing quantity of knowledge
needs to stay out there with no period of time on the computer server web. This can
be attained through load equalization plus clump methods that change the backup.
Another consummated objective is knowledge safety. This was attained victimization
two main methods. The primary was involved with internal safety, being enforced by
user permissions plus token primarily based verification. The second method is
involved with attacks initiated outside the net. So as to forestall system infiltrations or
knowledge capture VPN tunnels plus traffic sieves were designed at the sting of every
basic part.

Recent developments in Healthcare Networks.
 Some of the innovations in healthcare networks include:
 Payer-provider Analytics – This is where several carriers are giving
healthcare organizations claims data, tools and analytics to help make
better decisions are appropriate based on quantitative data.
 Competitor Analysis – Referral data is used by physical contacts to see
which competitor receives the most referrals in a certain place based on
specialty, procedures offered to be able to identify which organizations
could be the best to partner with based on referral volume.

Importance of security in healthcare
networks
 Increased mobility: Secure wireless networks and virtual private
networks allow clinicians to access patient information, lab results, and
medical libraries from notebook computers, handheld devices, and
portable phones, as well as from remote and home offices.
 Enhanced Productivity plus reduced costs - Once a secure, reliable
network is in place, healthcare providers can deploy applications that
streamline resource intensive back-office processes. Solutions can
include business management applications, claims processing systems,
and systems for finance and human resources management.

Current and Future potential security
issues
 Cloud threats – As hospitals use cloud-based applications to improve
patient care and collaboration, they should be concerned of data privacy
and security concerns.
 Encryption blind spots – Hackers have found a way to hide in encrypted
traffic. By using encrypted tunnels like virtual private networks in our
system we ensure data is passed in an encrypted way but it’s more
difficult for security analytics to detect or monitor breaches and targeted
attacks.

 In order to solve the encryption blind spots problem, hospitals should have a layer of
security to monitor traffic to ensure there are no blind spots for hackers to take
advantage. This will enable the IT department within the hospital to analyze all
network traffic for any suspicious activity taking place. Suspicious and malicious traffic
can be selectively decrypted and inspected in rapid fashion, while allowing known
good traffic to pass through in its encrypted state. This ability to selectively decrypt
and inspect network traffic ensures data privacy and compliance while bolstering
security against an increasingly common threat, which should always be top of mind
for hospital IT department and security staff.
