Best Free WiFi security tool (1)

Compared with earlier vrouters that were not encrypted or had insufficient password strength, and ignore the situation of modifying the default password of the gateway, Wi-Fi security has made great strides.

Poor product design and vendor laziness are potential threats. In addition, the wireless router broadcasts the user's network access and email operations to the surrounding area through wireless signals, which are ignored by users.

Most of the latest generation WiFi routers require password and user name setting, and use WPA2 and other encryption methods that are more difficult to crack.

Nowadays, as people connect to the Internet more and more frequently through public access points and other portable devices, wireless security is still a difficult problem.

Is it safe if the vro is correctly configured and the 128-bit or higher WPA2 encryption method is used? Unfortunately, this does not mean that your security protection is solid. In wireless security, this is only the most basic operation. Computer attacks and social engineering attacks are still a weakness in security protection, especially when computers are used on mobile devices. However, social engineering attacks do not need to hijack and sniff wireless connections.

Basic Security Tools

When we enter the keyword "wireless tool" in the search engine, we will find that the search results returned by the search engine are attacks and cracking tools that can intrude into others' Wi-Fi connections. These tools are worth installing in your laptop, because their most useful feature is to keep you updated on the access points around you.

The free basic tool inSSIDer is quite good. This tool is mainly used to solve wireless signal problems and interference from other access points. It can detect all the Wi-Fi devices around the Broadcast SSID. With this tool, you can see the signal strength (expressed as a negative number, the smaller the value, the better), stability, and information about the encryption system used by the Access Point. This tool can be run in all Windows operating systems. Which AP is connected in a public place? To identify a rogue AP from a valid AP, this tool is always better than no.

In addition to inSSIDer, Xirrus's Wi-Fi detector is also a good choice. Its functions are similar to those of inSSIDer, and the information provided is more detailed. A useful function is to use graphs to indicate the location and distance of an access point. The closer you are to an access point, the more frequent the sounds like the Gaige counter. This tool can physically locate rogue access points.

Wi-Fi detectors can effectively solve connection problems, not just security problems. The tool displays the Internet connection speed and application service quality provided by the local access point in percentages. The biggest advantage of Wi-Fi detectors is the continuous monitoring of the local radio environment as the background environment, rather than temporary monitoring.
