Wi-Fi is becoming more popular, and network security issues are imminent[Copy link]
As Wi-Fi networks continue to become more popular in American homes, more and more people are threatened by dangerous factors such as spyware, so it is urgent to strengthen system security. Even for IT professional Matthew, it takes almost all his energy to keep his home Wi-Fi network from being attacked from the outside . But for ordinary users, the complexity of Wi-Fi networks makes them think that security is not important. If manufacturers cannot launch products to change people's paralysis in time, the development of this problem will become more serious.
Although these aspects have tried their best to take some security measures, Matthew is still worried that someone will attack the Wi-Fi network he set up at home. He believes that there are still many inexperienced people who do not realize how vulnerable their wireless network systems are. According to him, running a home Wi-Fi network without security measures is like opening the gate and hanging a doorplate at home to invite thieves to steal. For untrained users , it is impossible to protect the security of Wi-Fi networks. According to experts, people encounter many difficulties when installing Wi-Fi networks, which makes them unwilling to spend time deploying other security measures or restart the installation to fix potential vulnerabilities . In addition, incompatibility between different vendors' equipment , the volatile industry security standards and the proliferation of devices that people want to connect to Wi-Fi networks have discouraged less tech-savvy users. Given all that hassle, it's difficult to get consumers to use security features built into wireless products, according to networking industry officials. "Ease of use is a big issue," said Manny, senior product marketing manager at Linksys. "Even if you have the best encryption technology in a product, it's useless if you can't use it easily. We've tried our best to make security an integral part of the network setup process, but it's hard to force people to use it." Gartner
predicts that by 2007, about 80% of U.S. home Wi-Fi networks will be considered "insecure." Gartner also predicts that by 2006, 70% of successful attacks on home Wi-Fi networks will be the direct result of improperly configured access point and client software. Tom, director of product management at Symantec, was shocked at a recent conference when four out of five attendees admitted that their home Wi-Fi networks had no security measures in place. Some people think that the idea of providing Internet access to others through their network is very novel and there is nothing to worry about. But what they don't think about is that if others can use your network connection to do whatever they want, it will have a negative impact on you. For example, if they access malicious content, it is your IP address that is tracked, and at the same time, the speed of the Internet connection will be reduced. According to Tom, users whose Wi-Fi networks can be easily hacked will also encounter other serious security threats. For example, hackers can "implant" malicious code such as spyware, adware, Trojan horses, etc. on their computers, which may lead to more serious problems such as network fraud and identity theft. According to some industry experts, secretly using someone's Internet connection outside their house is outdated. Signal boosting technology can enable hackers to use users' Internet connections from miles away. According to Carter, product manager of McAfee, the signal amplifier sold in the local RadioShack can enable people to access Wi-Fi networks within 50 miles. Users no longer need to worry about just their neighbors. As the threat becomes more serious, all manufacturers, including third-party software manufacturers and network tool manufacturers, are developing related technologies to help users protect the security of Wi-Fi networks. McAfee is developing a free diagnostic tool that lets users use a Web interface to check their computers and determine the security of the network they are connected to. The software, called McAfee Wi-Fi Scan, is currently in beta testing and is expected to be released in mid-February. Hardware manufacturers are taking a different approach. At CES earlier this month, Cisco's Linksys said it was working with Broadcom and HP to develop a one-button security system for home wireless networking products. The system, called SecureEasySetup, complies with the Wi-Fi Protected Access standard. Jeff, senior director of wireless LAN marketing at Broadcom, said SecureEasySetup is a basic security system that consumers can easily understand. He said that users can use SecureEasySetup to set up a secure Wi-Fi network without having to understand any technical details. Users only need to press a button on the router or Wi-Fi access point and then press a corresponding button on the PC or other device, and they can discover each other and establish a secure connection. Linksys will deploy SecureEasyStep technology in its products in early 2005, and HP plans to apply the technology to some models and desktops, notebooks and network printers. Jeff said that many other high-tech manufacturers will also adopt this technology. Force Field Wireless has taken an unconventional approach to ensuring the security of Wi-Fi networks. Its paint, called DefendAir, contains copper and aluminum, which can shield radio signals and prevent them from leaking out of the house. The paint sells for $69 per gallon, but only one color - gray. According to Jonathan, an analyst at Forrester Research, because it takes so much effort to ensure its security, it is still controversial whether wireless networks are suitable for consumers until more effective and easy-to-use security measures are available.
