WiFi jammer is a powerful protection method

The development and expansion of wireless technology not only brings us benefits and mobility, but also brings risks. The widespread commercial use of the company’s Wi-Fi wireless network has spawned the next generation of hackers for wireless attacks. Here, we will analyze the main risks of wireless networks and how to minimize or eliminate them.

First, you should know that traditional cable networks use wires to transmit data. They were protected by several serious means. The first line of defense is the physical boundary of the building where the network is located. Other defenses are firewalls and IDS / IPS traffic analysis systems.

Therefore, if the hacker wants to achieve his goal-he will have to dive into the building and connect directly to the network, or break through the firewall. Wired networks are better protected than wireless networks, because we will see the facts later. However, due to improper use of wireless networks, even these networks are easily broken.

You should keep in mind that wireless networks will never gain high security measures because they can be used relatively far outside the building. But the truth is, you can determine who is an external hacker by looking at the connection speed. The trick is that the weaker the signal, the weaker the connection, so if you use a 100 Mb / s connection and a 10 or 5 Mb / s connection appears, you can make sure someone is trying to connect from outside the building.

Therefore, in order to better understand the possible protection measures against wireless threats, let us take a closer look at their main content.

A thief is a device that can grant network access to a wired company through a wireless network. A typical example is a laptop computer with an active wifi blocker adapter connected to a local business network. Sometimes, these executives can connect to the nearest wireless network to get unlimited access to the Internet, or just send files to colleagues via Wi-Fi. Protected wired network and defenseless wireless network. Therefore, anyone can bypass the security protocol when accessing the company network through such a device. This is the most common risk in any network.

But notebooks can not only become “thugs.” Such tasks can be accomplished through Wi-Fi routers and many other Wi-Fi signal exchange compatible devices.

As I said before, wireless network users are mobile. They connect and disconnect several times a day, and the connection time is the most dangerous time on the network. When you connect to a wireless network, Wi-Fi devices send data packets with access codes to each other. A hacker can track and intercept such packets, and in this way know the secure password, and will violate your network.

Another common cause of network hacking is unprotected hardware failure. These are usually incorrectly configured supervisor tablets or personal laptops. They will act like “rogues”, giving hackers the opportunity to invade the network and spread malware in them.

Sometimes a company also tries to save money by buying consumer-designed hotspots and routers, which are poorly protected. You should always purchase company-designed hardware to protect your business information.

Many wireless networks still use outdated security protocols, such as WEP or WPA. Because they broadcast control packets in decrypted form, they are easily hacked. Therefore, the data packet containing the information required for the connection can be intercepted by any Wi-Fi site. All the hacker needs to do is aggregate through the wireless network and analyze it so that it can be fully accessed within 5 to 10 minutes.

Other protocols (such as EAP-FAST or PEAP MS-CHAPv2) are more reliable. Hackers will have to spend more time hacking these. The only “impenetrable” security protocol for wireless networks is WPA2-Enterprise. But this will not always be reliable.

Therefore, you will see that wireless technology not only brings us benefits, but also brings new risks. These risks cannot be minimized or eliminated by the methods used in wired networks. Wi-Fi is banned even in organizations, and some leaders can connect to wireless networks and put the entire company network at great risk. More and more companies have concluded that Wi-Fi scrambling equipment may be a suitable solution.
