Remote Access Business today never sleeps in large part to advances in technology. Because of this, users often need access to sensitive company data outside the office which presents many security challenges. Not only is the end user accessing your network resources and potentially sensitive data, but they are many times doing so from a public network which the admin has no control over and is open to others who may have malicious intent. These connections clearly need to be properly secured in order provide end users secure network connections. To secure remote connections, a virtual private network (VPN) will created using the Routing and Remote Access feature available within Windows Server 2012 R2. This feature allows end users to create a secure connection to the network by using Extensible Authentication Protocol-Transport Level Security (EAP-TLS) in addition to smartcards for authentication purposes. Traffic will also be encrypted by using Layer Two Tunneling Protocol over IPSEC (TechNet, 2016). To implement this configuration properly, the certificate authority mentioned above will be used to provide certificates to the servers and clients to authenticate and encrypt transmissions over public networks. The network firewall will be configured to accept this traffic and direct it to the VPN server. This configuration will allow secured remote connections to network resources for employees and end users.
Malware Protection To properly protect network resources
Virtual Private Networks (VPNs) are used to allow a remote public connection to an internal network. A VPN is essentially a virtual tunnel connecting a remote user (Tunnel Vision). The traffic within the VPN tunnel is encrypted, and there are two ways to do this. One way is Internet Protocol Security (IPsec) and the other is Secure Sockets Layer (SSL).
It is a protocol that allows users to access a remote network through a secure channel using encrypted passwords.
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
A VPN is a private network that uses a public network (usually the Internet) to connect
This implementation of secure remote access extends the secure network to the remote user using a secure PSTN (Public Switched Telephone Network) connection.
VPN refers to the networking technology Virtual Private Network. A VPN allows users connected to this network the ability to access any website or computer data from any location in the world with dedicated and secure networking environment rather than being present in a public server. Majority of VPN users belong to business class industry and educational purposes. VPN networks are used in this manner because majority of VPN networks offer the features like encryption and anonymity which increases the privacy and security benefits while using the VPN network. VPN networks also allow the user ability to perform activities on the internet as if they were accessing
The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.
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].
L2TP/IPSec is more complex. Both the user and the user's machine must be able to authenticate with the VPN server. Machine authentication can use either a pre-shared key or machine certificate. If you use pre-shared keys (not recommended for security reasons), check that the VPN client is configured to use the same pre-shared key as the server. If you use machine certificates, confirm that the VPN client machine has a machine certificate and that is also trusts the certificate authority that issued the VPN server's machine certificate.
This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.
A VPN is a secure protected network called a tunnel for communication purposes over long distances using the Internet as its means of transport. Due to the nature of the communication or transmissions that are being utilized by say a larger corporation, secure and reliable communication is a must. In the beginning these VPN connections were established using one or more dial up modems for users to access the information. Authentication was established by requiring the correct user name and password. As time went on as always things changed, new technology and advances in communication as well as equipment allowed the VPN to evolve and expand. To ensure security, the virtual tunnel is encrypted. VPNs use several protocols in order to encrypt
The network is currently running on Windows NT servers (University of Phoenix, 2006). An upgrade to Windows Server 2003 is suggested because it has better security built in than Windows NT servers. Using Windows Server 2003 the Internet Connection Firewall (ICF) can be enabled. The ICF, when enabled is designed to monitor the destination and source of IP addresses that come and go through the Internet. The ICF also discourages port scanning through the internet connection (Palmer, 2003).
SSL VPN is a newer VPN technology that links an employee’s computer to a corporate network via a web browser. No client software is required, meaning a larger variety of operating systems are potentially supported. The third type of VPN is mobile, in which one of the endpoints of the tunnel is not fixed (Bridwater, 2013).
VPN is a private network that uses a public network, usually internet, to connect remote sites or users together. It uses virtual connections routed through the Internet from the business's private network to the remote site or employee. VPN is used mostly by the employees who prefer to telecommute or work away from the office. By implementing VPN, the businesses make sure the data is encrypted and can’t be read by the ones who try to intercept the data. The computers at each end of the tunnel encrypt the data entering the tunnel and decrypt it at the other end. An encryption key determines what computations to perform on data in order to encrypt or decrypt it, however, a VPN needs more than just a pair of keys to apply encryption. Hence, a
Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
