If you’ve ever wondered what Wi-Fi stands for, then you’ve come to the right place. This technology is used in wireless networking and local area networking, allowing digital devices located close together to exchange data through radio waves. However, it is also susceptible to cyber attacks. This article will explain what Wi-Fi is and why you should keep it secure Malavida.
Wi-Fi is not an abbreviation of wireless fidelity
Many people are confused about the meaning of Wi-Fi. It’s a trademarked term used in conjunction with wireless technology. It doesn’t mean wireless fidelity, although most people would probably say that it does. Wi-Fi actually sounds like hi-fi, a word that means “high fidelity.” The word Wi-Fi is a proper noun, registered as a trademark of the Wi-Fi Alliance Cloudvents.
The term fidelity means “loyalty, continued support.” While the internet was often unreliable, WiFi wanted to change this. The marketing people who created it wanted it to imply a sense of trust and loyalty. Therefore, they coined the term “Wireless Fidelity”. It stuck around because people liked it and the term stayed.
It is not a network interface
When you run your Linux distribution, you may encounter a DNI_DNE error if you don’t have a network interface card. This error is caused by your hardware, so you must turn on the hardware switch to enable WiFi on your system. If the hardware switch is on, you will see an UP or DOWN message. If not, you need to load the correct driver in the kernel magazine999.
It is a wireless networking technology
WiFi is a type of wireless networking technology that uses the spread spectrum technique to spread signals over short distances. The spread spectrum technique breaks up a signal into several pieces and allows for lower power consumption per frequency. It also allows multiple devices to share a single Wi-Fi transmitter. However, Wi-Fi signals are sensitive to obstacles and can suffer from multipath interference kingnews33.
WiFi operates in two modes, ad-hoc and infrastructure modes. In infrastructure mode, a base station is used to distribute the network’s connection, while in ad-hoc mode, individual devices are connected directly.
It is vulnerable to cyber-attacks
WiFi is a popular way for people to stay connected, but it is also a vulnerable target for cyber-attacks. Unsecured networks are susceptible to wireless sniffing, which can reveal sensitive information. Hackers may use this technique to get around firewalls and NATs to hijack traffic and steal personal information hitwe.
One such exploit exploits Wi-Fi’s frame fragmentation feature. Fragmented frames are not checked for integrity by receivers, allowing an adversary to exfiltrate data. Once these fragments have been compiled, an attacker can use them to execute a mixed key attack.
These flaws affect all modern Wi-Fi security protocols. They’ve been dubbed FragAttacks, and have not yet been exploited in the wild. Because they require user interaction and uncommon network settings, the vulnerabilities aren’t suitable for large-scale attacks. In most cases, the flaws are related to programming errors that are in the Wi-Fi products.
It is uncrackable
It is essential for your WiFi network to be protected from hacking, especially if you run a business or educational facility. The number of cyber attacks is on the rise in almost every sector, including the business sector, and making your network secure is of vital importance. Using older security options like WEP can make your network vulnerable to attacks, so it is crucial to update your security. Using the latest WPA2 encryption algorithm will significantly reduce the chances of your WiFi network being compromised.
Hackers can use unprotected wireless networks to conduct illegal activities, including monitoring web traffic and stealing information. By conducting a Man in the Middle attack, these bad actors can intercept information sent and received over your network, allowing them to send phishing emails or hijack your online banking account.
