Implementation of Virtual Private Network

Question: Discuss about theImplementation of Virtual Private Network. Answer: Research on PBL Topic Analysis on VPN The application of the Virtual Private Network (VPN) in the industry level is analyzed in this report with the help of Project Based Learning (PBL) system. Here, the first organization taken for the VPN analysis is Johns Hopkins University and the second organization considered is Cisco. Johns Hopkins University This university was the very first research university present in USA and it is now wide spread globally for the purpose of teaching, patient care and scientific discovery in medicine field. This university is an integrated medical research centre. This centre has approximately more than 36,000 users with several email systems. Thus, here the main challenge faced is related to spam. An average of 60 percentage of spam was received from the total number of messages. This problem was resolved by the installation of four IronPort C60s. This successfully helped in protecting the universitys mail servers from spam. This mainly provides an optional outgoing VPN tunnel to the IronPort tech support [1]. It the university technicians to have access to the all the systems logged in without breaking any security hole. The University needed remote access, Transport Layer Security (TLS) and HIPAA related regulatory requirements related to email traffic and protected health information (PHI) for securing their research work. To resolve all these problems multi-function appliance was selected by the university, for a better deployment and maintenance, which is only possible with VPN. As it provides remote control, data security, better performance and low cost to maintain [2]. Thus, now the university is well protected. The execution of the VPN system requires the following steps [4]. The hardware specifications for the implementation of the VPN system on the management, RAM must have the capacity of 128 MB. The hard drivers are connected to each server. The co-axial cable is converted into Unshielded Twisted Pair (UTP) cable. The packages of the software which are involved in the process of accessing the VPN network has to be changed in the updated version. The server is to be changed according to the places which utilizes the VPN. It contains totally three servers for the execution. The network connectivity authorization is provided by a single server, and the other servers are used to serve as the SQL servers. The replacement of the co-axial cable with UTP cables provide highest speed and provides error free information to the client. Each server has the controllability for a secure information transaction over the internet. Finally, only the authenticated users are allowed into the secured connection of the VPN system to access internet. Cisco The Cisco Company introduced AnyConnect VPN client for the mobiles for achieving a secure network access from malicious software. The Ciscos software will automatically maintain the VPN connection with a corporate network, so the users need not connect manually. The AnyConnect, is a Secure Mobility Solution to provide security and better performance for the corporate workers who travel a lot. It also provided control over the SaaS applications like the Salesforce.com. The employees are not provided any direct option to login to the web application, as the Salesforce is managed by a secure gateway of Cisco. To establish connection with AnyConnect and users, first install AnyConnect VPN client on mobiles and the admin provides a link to the users through mail for authentication purpose and the encrypted connection is commenced. Relationship to VPN If a network is in a less secure condition with their other connection, then there is the requirement of the establishment of the secure connection. The connection should be secure and encrypted in order to maintain the privacy in the network, which is performed by using the VPN. The network without VPN is less secure whereas the network security increases with the presence of VPN. The security of the network when we using the VPN is more than the another security networks. In this system the remote sensing technology also included for the VPN technology. This is mainly suitable for the users of the hotspot and Wi-Fi system on the single organization level [3]. In Johns Hopkins University The IronPort C60s are installed four in number in the university to protect its mail servers from spam access. It provides secure remote access to the staff with SMTP authentication. It acts as a multi-function appliance for the university. Access to all the systems logged in to the network without breaking any security is known. Transport Layer Security (TLS) and HIPAA related regulatory requirements related to email traffic and protected health information (PHI) for securing their research work is possible by IronPort C60s. In Cisco Cisco AnyConnect VPN client provides secure network access. The Ciscos software will automatically maintain the VPN connection with a corporate network. It offers better performance. Direct option to login to the web application is not present, as it is managed by a secure gateway of Cisco. VPN monitoring with AnyConnect for mobiles is provided by Cisco. Involvement of Relevant Entities The Johns Hopkins University and Cisco have successfully generated a VPN system for their secure and privacy internet access for the university staff and for the Cisco customers. The backup of the entire information system is enabled by the organization. The Johns Hopkins University must be provided with effective appliance which can help in fulfilling the demands of the staff when they are away from the university. The staff must be trained how to use VPN system. The IronPort C60s contains functionalities that filters virus and helps in quarantining the suspicious in-coming e-mails. The implementation of IronPort C60s is cost effective for the university [1]. The fast process speed delights the customer, so it is suggested to enhance the speed of VPN for Cisco for more profit, as the AnyConnect VPN client is used for smartphone users. There is a facility of detecting the users automatically by the AnyConnect VPN client. This cost effective system. Hence, economically it reduces the expenses through the process of using the other techniques. It increases the 1500 VPN users simultaneously access the technique. In both the VPN system implementation, there are many factors that involved the users, operating facilities, benefits and its impacts. All of these factors and its impacts are being work on to help the VPN Technology to grow. References [1] L. Harbaugh, "IronPort C60 secures e-mail from all sides",InfoWorld, 2017. [Online].
