MN502 Overview Of Network Security In Emerging Networks


The purpose of this assignment is to develop skills to independently think of innovation. Students will be able to complete the following ULOs:

Explain the major methodologies for secure networks and what threats they address;

Identify and report network threats, select and implement appropriate countermeasures for network security.



The computer network or the data network is the digitalized telecommunication network that enables the nodes for the purpose of sharing various resources. The computer devices eventually exchange the confidential data or information with one another with the help of data links within the nodes [9]. The data links could be established with cable media like optical cables or wires and even wireless media like wireless fidelity. The significant utilization of the network technology is growing rapidly within the health care sector. This health care is subsequently considered as the emerging application of several network based applications [2]. The various networks could provide efficient as well as effective solutions for numerous factors like accessing EMRs or electronic medical records, biomedical information, online claims submission, medical management system, patient accounting, materials management, admitting information and many others [3]. The health care networks are extremely important and vital for the entire sector of health care. The following report outlines a brief description on the several security challenges in emerging networks in health care sector. The architecture of this network, current developments and the importance of security will be provided here.

Architecture Of Health Care Network

The health care sector comprises of the organizations, which provide significant medical services and medical insurances, manufacture medical drugs or equipment and facilitate provision of the health care to their patients [12]. This health care sector comprises of the diverse array of several industries and also with the activities that range either from research to manufacturers or to the facilities management. The makers of medical equipment eventually range from the firms, which manufacture standard as well as familiar products like forceps, gloves, scalpels and bandages. The patients or the health care experts are benefitted from this particular sector. The network of this health care is responsible for providing several benefits to these patients of health experts [7]. The entire architecture of the health care network depicts a clear understanding of the routers, switches, servers, clients, gateways and firewalls.

The above figure depicts a clear image of the server farm, clients, gateway and OAM server. These are the major components of this network architecture. The architecture is completely on the basis of the major concepts of SONA or service oriented network architecture [3]. These concepts are sub divided into three structural components, which client level, infrastructure level and finally server farm level. The designing of advanced network capability is done within the infrastructure.

Recent Developments In Health Care Networks

Health care networks are bringing recent developments for the users worldwide. Various development programs are being implemented especially in the rural areas [8]. The major purpose of these developments is to assist within the proper development of the integrated health care network. These health care networks could be the most efficient and effective strategies for achieving the efficiency as well as economies of scale. The main goal is to increase the communications and hence mitigating the recent issues of communication. Moreover, the information is often vulnerable and hence could be easily hacked by the hackers [1]. The recent developments of these networks will ensure that the confidential data or information is not lost under any circumstance.

Security is one of the major requirements in health care networks. The security of network is the proper protection of the access, destruction, misuse and finally hacking of the directories or files within the computerized network system [5]. Some of the major threats to this network are viruses, spyware, adware, worms or identity theft. The importance of this security within the health care network is that it would detect as well as prevent the entry of viruses or other threats. Moreover certain security measures like encryption encode or hide the confidential data into a cipher text, so that the hacker does not get access of it [10]. As the health care networks store sensitive data such as patients’ details, there is a major importance of the security in networks.

Three Potential Security Issues In Health Care Networks

There are various potential and vulnerable issues related to security within the health care networks. Amongst them, the three potential security issues in these networks are as follows:

  1. i) Distributed Denial of Service Attacks: The first and the foremost security issue that is dangerous for the health care network is the distributed denial of service or DDoS attack [4]. In the denial of service attack, the attacker seeks into the network resource or machine with the major purpose of making that particular machine completely unavailable for the intended and authorized users. This is done by the permanent or temporary disruption of services for any typical host that is linked with the Internet connection. This type of attack could be eventually achieved by flooding the targeted resource or machine with various superfluous requests with the core attempt of overloading the systems and then preventing the legitimate persons from accessing confidential data or information [6]. Within the distributed denial of service attack, the respective incoming traffic is flooded by the attacker so that the victim does not get data from sources.
  2. ii) Man in the Middle Attacks: The second popular and significant security issue for the health care network is the man-in-the-middle attack [1]. This is the type of attack, in which the hacker secretly relays or even alters the confidential data within the two parties, who have the belief that they are communicating directly with one another. The most significant example of this man in the middle attack is eavesdropping.
