What is the difference between WEP and WPA?

WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) are both security protocols designed to protect data transmitted over wireless networks, but they differ significantly in terms of security and encryption methods.

WEP:

• WEP was the first security protocol introduced for wireless networks.
• It uses a static key and the RC4 encryption algorithm to secure data.
• WEP is considered highly insecure due to vulnerabilities that allow hackers to crack the encryption relatively easily.
• It is not recommended for use in modern wireless networks.

Example: If a network uses WEP, an attacker could potentially intercept and decrypt the data being transmitted with relatively simple tools and techniques.

WPA:

• WPA was introduced as an improvement over WEP to address its security flaws.
• It uses a more robust encryption algorithm called TKIP (Temporal Key Integrity Protocol) and later versions of WPA (WPA2 and WPA3) use AES (Advanced Encryption Standard).
• WPA provides stronger security and is more resistant to attacks compared to WEP.
• WPA2 and WPA3 are currently the recommended standards for securing wireless networks.

Example: A network using WPA2 would be much more secure, making it extremely difficult for an attacker to intercept and decrypt the data.
