Introduction

In the same way that corporations must secure their wireless networks, so too must we safeguard our infrastructure, whether it be in the cloud or on-premise. Protecting wireless networks from threats including hacking, data eavesdropping, and harmful assaults. Its significance is undeniable, given that an attacker can compromise the network, but Wi-Fi makes this prevention possible. Although most data breaches occur in the workplace, they can happen anywhere, including at home or in public. This is why I have been concentrating on breaches at organizations so far.

As a rule, we safeguarded allowed access and data confidentiality by using wireless security protocols. Safeguarding them will allow us to forestall the vast majority of network abuses. Achieve or improve this level of wireless security by implementing appropriate protocols. These wireless security protocols aid in keeping data available, private, and undamaged all at once. Here, we can go into detail about these protocols.

WEP: Legacy security protocol

As an authentication mechanism, this method makes use of a shared key. Access points (APs) and client devices both produce and exchange shared keys. Authentication and encryption both make use of this key. In order to authenticate with the AP, the client includes the key in an authentication request. RC4 uses the bitwise XOR operation to combine plaintext data with a stream of pseudo-random bits.

One issue with this approach is key management; since the key needs to be manually set on both the AP and the client, it becomes a pain to implement changes. The adoption of RC4, an easily-cracked encryption algorithm, is another issue. Since the initialization vector (IV) length is only 24 bits, any brute forcing tool can quickly estimate it. Similarly, this method uses a predictable initialization vector. Since no one wants to use it because of all the security holes it contains, it is considered a legacy approach. More robust procedures are required to safeguard wireless as we embrace more modern technology.

As an intermediate solution, it is a forerunner of the more permanent WEP. When compared to…
