There are several different types of services available today, to help promote internet access. Windows RAS is a service that is available on many different operating systems. It is used all around the world to access computers remotely. Windows routing is another service available, which is used to route addresses. Over the past years, remote access appliances, and routers has become available.

RAS is a service that provides remote access capabilities to client applications on computers running Windows. RAS is capable of controlling several functions. A few of the functions are common dialog boxes, connection operations, server administration, and security host support. While using the RAS connection operations, you can use the common dialog boxes or low level dialing functions to start and end a RAS connection. You can work with entries in the RAS auto dial mapping database to map network addresses to the phonebook that will establish a connection. RAS also handles administering of user permission and ports on servers. By setting up a RAS server administration application, you can enumerate users that have a specified set of RAS permission. You can also reset the statistics counters for a specified or disconnect a specified port. RAS's administration DLL decides if a user should be allowed to connect to a server that will supply a security check in addition to the standard user credentials. Each time a user connects or disconnects from the server it will be recorded by the RAS administration DLL. The RasAdminAcceptNewConnection can be implemented by using the RAS administrations DLL. RAS have its pros and cons to offer also. One of RAS's cons is RAS clients cannot gain access to the internet by just using a network access address. The pros is you can configure the NAT protocol on a server running routing and remote access services which will allow access to the internet by clients with private addresses.

Windows Routing appliances is used to configure Windows Home Server network using a Static IP Address. When you are using a routing appliance every computer requires its own unique designation to be directed to the correct location when information is transferred across the network. When routing a network always make sure that the IP address that is being used do not conflict with the other DHCP clients on the network. The best choice is to use the highest possible address when configuring. It is also a great idea to assign a static address to the Windows Home Server machine. Windows routing has numbers assigned using the dotted-decimal notation (subnet mask) to show the access lists, inspect interfaces, show ip dhcp pooling, and the ip dhcp server statistics. During routing you can allow the Configure Manager to distribute information to its client's computers on a secure network using firewall. Although this feature is the most-used feature it is also the most dangerous if not used carefully. The Configure Manger can choose to set up for the servers to share folders, media or documents with others on the network. The network setup using routing has its advantages making it necessary for servers to have their own private access passwords to enter into the domain. The network using this feature can protect and keep the servers from entering a dangerous site that can cause serious harm to the whole system. There could also be some disadvantages to Windows Routing. The system that is using the Windows Routing appliance should always have a good secured network such as firewall to protect the valuable information being used making impossible for crackers to get into files to copy passwords and accounts. The Windows Routing appliances are being used in home and work groups around the globe. So far it has been a very successful tool used for networking with multiple servers assigned to a specific domain.

A remote access appliance is typically used to provide secure connectivity to home-based networks. A remote access appliance can be Windows-based applications and desktops. The remote access appliance when used on a Windows operating system can lock down a system to ensure that only those intended to have access can actually be granted permission. Using the internet in a public setting can pose serious risk and security issues if not properly secured. The remote access appliance assures that the private transmission being sent through a public network will be secured. Employees access the internet on a daily basis opening multiple sites that maybe dangerous for the system. When using a secure access appliance attributes can be locked down such as Called-Station-ID, Caller-Station-ID, Client-IP-Address, and Tunnel-Type. The history of a server can also be logged which includes your financial accounts, authentication request and periodic status. The remote access appliance such as routers and modems has multiple responsibilities when connected to a group accessed network. The good qualities of having the remote access appliances installed to your system, is that it can secure your private passwords and account information being sent via internet. It can allow only the administrator to have access to the network using a private access password. Unfortunately it has flaws which encouraged the invention of VPN's.

A machine that has been implicated to work along-side the remote access appliance is the VPN. It is the Virtual Private Network, which only a virtual private connection is provided between two communicating partners. There is no real direct network connection, making the network private where only the members of the company or group are allowed to access the information that has been transferred. VPN's are being used over remote access appliances to ensure more safety and security of the data being transferred. It also has an increase in speed when searching the internet. This disadvantage of the remote access appliances paved the way for the production of the VPN's now is being used in corporations and home-based group networking, safely securing networks with faster connections.

Routers are being used in home-based and corporations connecting two or more single networks to form a large network. When using a new router always change the default logon password and username. Routers can work collectively to route packets across multiple networks sending a device toward the destination. Routers can provide security to a network but needs protection against virus attacks. Simple Network Management Protocol (SNMP) is a part of the TCP/IP protocol suite. It allows computers and network equipment to gather information about the network's performance. It is particularly crucial that when using a router that includes a wireless AP that the default administrator password be changed periodically. Hackers try to access the router if it comes visible in their list of available networks. This can be impossible if you block all users with a strong private access password which makes your router invisible or unable to access. Sometimes there can be a signal leakage; hopefully that problem can be minimized keeping the wireless network secure while using the router.

Cisco Routers can be good devices if used securely and properly with strong private access passwords to block out unauthorized users. When having routers there could also be some problems that may occur. When sending passwords through the SNMP station they are not always encrypted leaving your system vulnerable to hackers to capture you passwords and data in plaintext. A hacker can implement a denial of service (DoS) attack or man-in-the-middle by repeatedly sending spoofed update messages to Router A and B gaining access through Router C. This causes a huge problem which deletes all administrator passwords making the system vulnerable to retrieve valuable data and passwords.

When comparing all of the tools used to operate a Windows system all of them could be very helpful. They all have their advantages and disadvantages making it hard to decide which would be the better option to use if I was setting up a home-based group operation. Each tool would very useful as well as necessary for safety and security purposes. When using Windows RAS users can use a remote address to access the database with a password. When using Windows Routing you will also need to have an administrator password to gain access to the database. Remote access appliance protects your information from potential vulnerabilities. They provide security making it almost impossible to retrieve the valuable information that is stored into the system that is being used. Routers are very necessary when setting up a home-based network using multiple servers. The routers can be set up to block unauthorized users that do not share the network or has the administrator password.

I personally would rather use the Remote access appliance that has been implemented to improve the security and performance of the system and network. Remote access appliance is very secure and safe to use especially when sharing network with multiple users. Having your own password can keep your personal files and documents safe from crackers. There are so many dangerous sites just by opening on your browser can start a chain of events to disable your whole system. I believe that when having remote access appliances you are not left vulnerable to intruders and your system is safe. You will need to continue to keep it secure with strong access passwords that you change periodically

In the new millennium remote access appliance such as VPN machine is making a big impact on Window servers. The industry of corporations and home-based businesses prefers access appliances over Windows because of its safer features. The security of having the remote access appliances has increased since just using Windows. I tend to agree with the new trend to use them. I believe that as we grow into the millennium and the internet is being used more often, more of information needs to be secure and safe from intruders. There are victims every day that are being taken advantage of with identity theft. When sending your valuable documents and passwords via internet, you expect it all to be protected. When using remote access appliances it is possible to always keep your information safe and secure with firewall and spam blockers. These features can be automatically installed to protect your system from dangerous sites and crackers.
