Growing business users connect to the Internet using connections through Wi-Fi hot spot. For them security is an essential aspect. Indeed, the hot spot is the ideal venue to carry out interceptions, to transmit viruses, or simply to take advantage of users who have computers with weak defenses.
However, the hot spot Wi-Fi can make a business trip much more productive. It has never been easier for travelers to stay in touch with his office and his home. Passengers can pay occasional service function use, time or day. Who travels frequently can activate an account with a fixed monthly. Those who prefer the free services may instead seek those available through Wi-Fi free.
Fortunately, you do not have to avoid use of the hot spot to escape to those who try to enter into your computer via wireless. Start by taking some simple precautions to increase your system defenses.
1. Disable sharing.
The share printers and files may be necessary within its own business and home networks, but should be avoided in public networks, where the unknown can see, read and write even in areas shared. To prevent this from happening in the Windows host, open the Properties wireless connection and make sure that "Client for Microsoft Networks" and "File and Printer Sharing for Microsoft Networks" are not selected.
2. A firewall for your laptop.
By default, hosts of Windows "listen" many doors TCP and UDP port open and each represents a potential vector of attack. If you are a user of Windows XP, close these passages allowing the firewall in Service Pack 2 to ensure that your wireless connection is not defined no exception. If you use another operating system, install a firewall of others. In this sense, you may download the free programs provided by ZoneAlarm, from Comodo or Kerio. The larger company as security should consider firewalls centrally managed desktop as Sygate Enterprise Pretection Symantec or CyberArmor Firewall InfoExpress.
3. Check your connection.
Many programs wireless client - including the service XP Wireless Zero Config - automatically connect to any access point (AP) available. This can be handy in the office, but is a practice little suited to public networks. With regard to control, configure your wireless clients so that colleagues only with your permission. For example, the panel XP Wireless Network XP use the Advanced button to clear "Automatically connect to non-preferred networks" and select "Access point (infrastructure) networks only". If you use SP2, configure each "Preferred Network" in order to disable the car connection. Finally, disable these connections when not in use.
