The world of Internet users is growing daily. Millions of people are more interested in this type of technology. People like the wireless networks at home, but that isn’t the only place that the security of wireless system broadband networks come into question. The workforce is using these systems. Mobile employees that are on the road a lot will use this type of technology. There are also consumers and all types of environments where wireless networks are used:
By default, Windows systems generate an entry in the security event log by processes using the local and network service accounts. These accounts are used by services that need fewer privileges and logon rights on a local system, and access to network resources in case of the network service.
Windows 7 gives you the ability to create a home network through which you can share resources among your home computers and devices. Home computers are normally assigned to the Home network location where such designation allows you to use HomeGroups. HomeGroups make it easier to share resources in environments where Active Directory does not exist. HomeGroups cannot be created on a domain network but you can join an existing one while you are part of a domain. For example, you could join a HomeGroup on your home network and at the same time connect to your work’s domain network through a VPN connection.
If you want to get a quick check of network problems on your computer then you can check the status of packets in error. By default, only the numbers of bytes received and sent are displayed in the Local Area Connection Status window but you can have the number of errors displayed as well. With this registry tweak you can display an errors counter below the sent and received numbers.
The NLA (Network Location Awareness) feature assigns your Windows 7 computer a network profile based on the properties of a network connection. When you connect to a new network, Windows prompts a dialog box asking you whether the network is a Home, a Domain or a Public network. Additionally, Windows 7 remembers the designation that you assign to the network and associates it with the properties of the network so that every time you connect to that network, the same designation will be applied.
Windows 7 native firewall is based on two sets of rules that complement each other. The basic Windows Firewall uses simple rules that directly relate to a program or service while the Windows Firewall with Advanced Security (WFAS) allows for more complicated rules that filter traffic on the basis of port, protocol, address and authentication.
Netstat displays protocol statistics and current TCP/IP network connections. With Netstat you can collect connection statistics about the names of the protocols (TCP or UDP) used, the IP addresses of both local and remote computers, the ports used for both local and remote computers and the state of TCP connections.
