Wifi Security Issues and Solutions

We are always connected to the Internet. We do this using phones, tablets, laptops, gaming systems, and cars. While some of these use wired and others use proprietary communication methods (albeit wireless), we'll focus on Wi-Fi and Wi-Fi security issues. I think this is the point of lack of awareness and I hope to use this blog to educate more people about Wi-Fi security issues.
What is Wi-Fi?
Wi-Fi is a playback method of Hi-Fi (high fidelity), which is the quality of sound. While it's not a direct pun (all wireless is pure wireless or wired; no wireless quality), it is wireless and uses radio frequency (RF) rather than wire (Copper) or fiber (Light). The International Organization of Electrical and Electronics Engineers (IEEE; commonly referred to as I-Triple E) maintains this standard along with many other organizations in various standards committees. The LAN/MAN Standards Committee (802) oversees this and oversees several other matters including Ethernet, Token Ring, and Bluetooth. Within 802.11 (the IEEE working group for wireless LANs), new standards have emerged over time as the ability to broadcast data using RF has evolved. Technically, 802.11a is completely different from 802.11g in terms of standards, they are interoperable standards. 802.11g is the revision and merger of 802.11a and 802.11b, which was superseded by 802.11n and later 802.11ac. There is an 802.11ad, but it's in a different frequency range and less common. последовательный конвертер rs232 в wifi
Below is a list of the various 802.11 protocols and their maximum speeds and frequencies over time. Note: Maximum speed may vary based on implementation, bandwidth, channel size, and environmental factors. The following values ​​relate to the standard ratings.
802.11a
Frequency: 5.0 GHz
Typical top speed: 54 Mbps
802.11b
Frequency: 2.4 GHz
Typical top speed: 11 Mbps
802.11g
Frequency: 2.4 GHz
Typical top speed: 54 Mbps
802.11n
Frequency: 2.4 GHz or 5.0 GHz
Typical top speed: 600 Mbps
802.11ac
Frequency: 5.0 GHz
Typical maximum speed: 6 Gbps
How does Wi-Fi work?
In the traditional and simplest sense, it is a way of communicating over a network (without wires) using radio frequency. Data is delivered and encoded/decoded using the 802.11 standard-compliant antennas and routers discussed above. Radio processes data in the kilohertz (KHz) and megahertz (MHz) range, while Wi-Fi processes data in the gigahertz (GHz) range, which is the 2.4 and 5 GHz range (as of now). So, in contrast to wired networks, anyone can "touch" your communication medium. This may cause some security issues.
Before discussing Wi-Fi attacks
Before talking about technical attacks on Wi-Fi, want to dispel some myths and raise awareness of Wi-Fi security issues, including open, public, and customer Wi-Fi networks. One thing that is unique to all of them is that they are not safe for the most part. Like anything, there are exceptions, but this article deals with most sub-exceptions. Модуль связи CAN2.0
Security issues of wireless networks in enterprises
Instead, when you use a customer network, you give up security in two ways: The network you're connecting to may or may not require a password that anyone can obtain. You can't be sure about the security of a network, or even verify and confirm that it's really a network and not an "evil twin". You cannot* ensure that no one can intercept and read and/or modify your data. Also, while not dangerous but still annoying, stores can also monitor your connection, and based on a nice picture of you clicking "OK" to connect, they can query your device and get data about you. This data could be your installed apps, location data, etc. The same goes for installed apps (Walmart Savings Catcher, Macy's App, etc.). These stores also have no legal obligation or responsibility to protect the data on your device or network. Moral obligations and responsibilities are different.
Public Wi-Fi Security Issues
If anything, public Wi-Fi networks (those with pre-shared keys, for that matter) aren't much more secure. Although their intent may differ from retail stores, they do not have any warranty or legal obligation to protect your device or data. Likewise, you cannot* ensure that no one can intercept and read and/or modify your data. You should question why this network exists, especially if the connection is free. Through data mining (such as the retail store above) or through advertising, you may be the "product".
