Opportunities and Risks of public Wi-Fi wireless Internet access

One hour before the plane leaves, you need to log on to the Wi-Fi network at the airport, view stock information, watch emails, and browse websites. This is not a dream, but a reality. Wireless Internet access is now available at airports, coffee shops, hotels, and other hot spots. This means that anyone on the wireless network can read the files you send by installing the necessary software. In case of protection, it may be a WEP encryption technology, which is easy to crack.

According to a survey conducted by AirTight Networks, which sells wireless access products, 14 airports in the United States and Asia, 57% of the Networks are open, including public and private Networks, such as baggage handling and air ticket check. 28% of networks are protected by WEP technology, while only 15% of airports use WPA, a powerful security technology ).

When browsing available Wi-Fi access, you may encounter a malicious network dedicated to attacking unprotected computer systems. If you are an open private network operator, your system may be attacked by hackers, even though this is not found in the investigation conducted by the Organization.

Obviously, enterprises can perform self-correction when operating open networks with poor security protection. This method can also be used at home. If you have an old wireless router, you can use WPA technology. However, when you leave home to view public wireless access, you can take the following steps to ensure security.

Make sure that the business boss provides the virtual private network access (VPN) service for business travelers. In this regard, whether employees remotely access the enterprise network or use the enterprise computer on the public network, all enterprises should require employees to use the VPN. VPN provides end-to-end traffic decryption. If someone intercepts data, he will only see the network address of the VPN gateway, rather than seeing more valuable things. If you do not have VPN support, you need to enter a secure network.

Even if you access the public network, you can log on to such security websites with confidence. If you access an insecure website, such as Hotmail, Gmail, Yahoo, and other popular email service networks, some attackers can easily obtain your information. If the login page is not secure, you can search for HTTP or password protection.

Public Wireless Networks are widely used and play a major role. However, risks also exist at any time. Mastering security knowledge helps users access the Internet over wireless networks more securely and quickly.
