WiFi jammer is a powerful method of protection
The development and expansion of wireless technology brings us not only benefits and mobility, but also 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 wired 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, as 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 have high security measures because they can be used relatively far outside the building. But the truth is that you can tell 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're using a 100 Mb/s connection and a 10 or 5 Mb/s connection pops up, you can make sure someone tries to connect from outside the building.
Therefore, in order to better understand the possible protective measures against wireless threats, let's 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 with an active wifi jammer adapter connected to a local corporate network. Sometimes these executives can connect to the nearest wireless network to get unrestricted internet access, or just send files to co-workers over Wi-Fi. Wired Network Protected and Wireless Network Undefended. Therefore, anyone can bypass the security protocol when accessing the corporate network through such a device. This is the most common risk in any network.
But notebooks can not only become “rogue”. These tasks can be accomplished through Wi-Fi routers and many other devices that support Wi-Fi signal exchange.
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 each other data packets with passcodes. A hacker can track and intercept such packets, and thus know the secure password, and will breach your network.
Another common cause of network hacking is unprotected hardware failure. These are usually poorly configured supervision tablets or personal laptops. They will act as “thugs”, giving hackers the ability to invade the network and spread malware inside them.
Sometimes a company also tries to save money by purchasing consumer-designed hotspots and routers that are poorly protected. You should always purchase hardware designed by the company to protect your company's information.
Many wireless networks still use outdated security protocols, such as WEP or WPA. Because they stream 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 has to do is to aggregate through the wireless network and analyze it so that be fully accessible in 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 them. 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 brings us not only benefits, but also 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 executives can connect to wireless networks and put the entire company network at great risk. More and more companies have concluded that Wi-Fi jamming equipment can be a suitable solution.
