Risk Management or Assessment To lessen the exposure of the corporate network to outside sources, there are many matters to consider. Areas of concern with the VPN client that should be addressed include: the potential hazards of the “always connected” nature of broadband Internet connections, installation of personal firewalls, antivirus software, and the remote PC itself. Analysis of the client PC begins with the PC itself. It is recommended that security policy require the VPN host to be company issued equipment, rather than using the existing user’s personal property. This eliminates problems associated with mixing business and personal information. When under company ownership it is easier to require the end user to comply with policy, and insist the PC be used only for business-related purposes. As the hardware is company-owned, users will not be given administrator account rights on their desktop machines. Controlling user activity as well as checking and maintaining desktop integrity is very difficult (if not impossible) when users have complete control through administrator rights. Company provided hardware also serves to minimize management issues, as the computer should remain relatively static - with no unauthorized software installations, end-user configuration changes or device conflicts to troubleshoot, support calls are reduced. In addition to

VPN is the abbreviation of Virtual Private Network. A VPN can extend a private network (like local network) across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, and thus benefit from the functionality, security and management policies of the private network [7].

A good VPN can provide many functions such as access anywhere worldwide without dedicated lines, data security, remote access to business resources and better employee production. For these VPNs to perform these functions properly they are required to provide reliability by ensuring that the network does not break down before reaching its max capacity, scalability to ensure the ability to expand as business grows, and of

To fully explain the acceptable use policy would mean to begin from the beginning, the user domain. The user domain is the employee or people within an organization who is granted access to the information system for the organization. There are roles and tasks, responsibility, and accountability that go into an acceptable use policy for the user domain. Within the user domain is the access of LAN to Wan, web surfing, and internet. LAN to Wan is the activities between LAN to Wan and firewalls, routers, intrusion, detection, and workstations. Web surfing determines what a user can do on company time with company resources. Internet

Corporation Tech IT may suspend network access to any location or system that disrupts normal network operations or systems that violate Corporation Tech policy. In this event, an attempt will be made to contact the responsible individual to resolve the problem.

With this process, the host is checked against the corporate policy to determine if the host is compliant or not. With this check it determines what level of network access that the host will be given. Cisco network access control is also a posture based access control. With this access control comes two solutions: 802.1x and Clean Access; 802.1x solution will make use of a RADIUS server which will be used for authentication. Clean Access authenticates users through a web browser, which also checks to see if the user is compliant with the enterprise

This policy defines the security configurations users and Information Technology (IT) administrators are required to implement in order to ensure the integrity, availability, and confidentially of the network environment of Richmond Investments(R.I). It serves as the central policy document with which all employees and contractors must be familiar, and defines regulations that all users must follow. The policy provides IT managers within R.I. with policies and guidelines concerning the acceptable use of R.I. technology equipment, e-mail, Internet connections, network resources, and information processing.

Company Implemented a disaster recovery site which is in Billings, Montana. Solomon Enterprises have VPN connection for users to work remotely

POLICY - Policies define security configuration, user information & admins are responsible for implementation order, this is to ensure the integrity, availability, & confidentially on the Richmond Investments networks. It acts as the main policy from which all employees & contractors must be familiar with, this also defines regulations that all users are mandated to follow. This policy provides the Information Technology managers in Richmond Investments with the mandatory policies & guidelines concerning acceptable use of Richmond Investments’ equipment, e-mail, Internet surfing, network resources, windows explorer, & information processing.

In today’s advanced world of technologies remote work arrangement is a normal thing. It is an important step of creating flexible work force. But there are certain risks associated with remote access such as unauthorized access, leakage of confidential information. So to minimize these potential risks a secure policy is required. Remote access policy tries to minimize the risks associated with remote networks by defining the system requirement for remote users before they are allowed to connect to the organization’s network. Remote access policy defines standards for connecting to organizational network and security standards for computers that are allowed to connect to organizational network.

Security and privacy is and always will be an important subject in regards to computing, weather its successfully securing clients data or protecting a personal network from would be hackers, the concepts of security and privacy will always be at the forefront of any individual’s mind. Due to the constant need for more security as well as privacy the concept of a VPN or Virtual Privet Network was introduced and implemented. This report will first go into detail on what a VPN actually is, how VPNS work, what their capabilities are and how they can be implemented into an organisations security policy. The report will later detail what IPsec is and IPsec tunnels

Furthermore, the audit states that no virtual private network (VPN) exists currently, something that the auditor and company may be unaware of is that this is a significant issue. It has become a necessity in business to enable employees, managers, contractors etc. to access confidential resources through public networks away from the workplace with confidence that they are secure in doing so.

The benefits of using VPNs are reduced cost overhead, reduced management overhead, and added security (Microsoft Press, 2000). Least network lines are expensive and VPNs reduce then need for extra data connections. This in turn also aids in reducing the amount of overhead associated with managing a network. The added security benefits for a network include encrypted transmission of network data and

With the increasing popularity of the Internet, new technologies have introduced to provide secure access to the resources from remote clients. Virtual Private Networks are becoming the most universal method for remote access. They enable service provider to take advantage of the power of Internet by providing a private tunnel through the public cloud to realize cost savings and productivity enhancements from remote access applications. VPNs securely convey information across the Internet connection to remote users, branch offices and business partners into an extended corporate network. This paper is an attempt to provide an overview of VPN and its services and how the

VPN allow employees to securely access a corporate intranet while located outside the office site. They are used for geographically separated office of an org. to connect as one network. Individual user can use wireless transaction with VPN, to circumvent geo-restriction and censorship, or to connect to proxy servers for the purpose of protecting personal identity and
