Therefore, we always use complex passwords on our modem routers to prevent them from being easily hacked. <a href=\"https:\/\/ded9.com\/training-on-troubleshooting-and-solving-the-problem-of-not-connecting-to-the-wi-fi-network\/\">Wi-Fi<\/a> Network Security, however, is provided by a series of Security protocols that have abbreviated letters.<\/p>\n<p>Therefore, it is likely that many users will struggle to recognize the superiority of these protocols.<\/p>\n<p>Due to the importance of this issue, we have decided to introduce you to these protocols and examine their differences. <b>Stay<\/b> tuned for the difference between WPA, WPA2, and WPA3.<\/p>\n<p><iframe title=\"WiFi (Wireless) Password Security - WEP, WPA, WPA2, WPA3, WPS Explained\" width=\"800\" height=\"600\" src=\"https:\/\/www.youtube.com\/embed\/WZaIfyvERcA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h2>Introducing the differences between WPA, WPA2, and WPA3 standards<\/h2>\n<h3>WPA<\/h3>\n<p>The first Security protocol used in the Wi-Fi world was the Wired Equivalent Privacy (WEP) protocol. Still, with the increase in the number of cryptographic keys, WEP has encountered numerous Security holes in recent years, making it practically inefficient and vulnerable to simple hacking through free software, which can easily compromise passwords using this protocol.<\/p>\n<p>To address the problems of WEP, in 2003, the introduction of WPA, which stands for Wi-Fi Protected Access, occurred. The protocol, which itself has several versions, including WPA-PSK, uses 256-bit keys.<br \/>\nThe protocol was equipped with features such as MIC (to detect modified packets between two points and enhance System integrity). However, TIKP was designed to be WEP-compliant. This is why WPA is not as strong against attacks as WEP.<\/p>\n<h3>WPA2<\/h3>\n<h3><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-258488 aligncenter\" src=\"https:\/\/ded9.com\/wp-content\/uploads\/2021\/02\/WPA2-1.jpg\" alt=\"WPA, WPA2 And WPA3\" width=\"1400\" height=\"600\" srcset=\"https:\/\/ded9.com\/wp-content\/uploads\/2021\/02\/WPA2-1.jpg 1400w, https:\/\/ded9.com\/wp-content\/uploads\/2021\/02\/WPA2-1-300x129.jpg 300w, https:\/\/ded9.com\/wp-content\/uploads\/2021\/02\/WPA2-1-1024x439.jpg 1024w, https:\/\/ded9.com\/wp-content\/uploads\/2021\/02\/WPA2-1-768x329.jpg 768w\" sizes=\"(max-width: 1400px) 100vw, 1400px\" \/><\/h3>\n<p>This trend continued until 2006, when the introduction of the WEP 2 protocol was observed. Instead of TKIP, the protocol used the AES and <a href=\"https:\/\/en.wikipedia.org\/wiki\/CCMP_(cryptography)\" target=\"_blank\" rel=\"noopener\">CCMP<\/a> algorithms, which were much more powerful. WPA2 still uses TKIP.<\/p>\n<p>The same changes made WPA2 much more secure than WPA, but there were still problems. This Problem is more common in large organizational networks.<\/p>\n<h3>WPA3: The latest Network Security standard<\/h3>\n<p>In 2018, however, the WPA3 protocol was introduced. WPA3, the latest Security standard developed, is more secure than previous standards. This standard addresses one of the most significant issues with modems. WPA3 essentially prevents hacking of wireless modem passwords. This standard prevents obtaining a password through Brute Force (guessing the password by testing all available characters) or other hacking methods.<\/p>\n<p>This standard has taken a cautious approach. You can restrict access to your information, even if a hacker obtains the modem password in any way.<\/p>\n<p>Among the key features of WPA3, we can prevent password hacking, detect and prevent offline attacks, and the forward secrecy feature (if the hacker has already obtained part of the data and, after a while, succeeds in decrypting the password to decrypt this data, they cannot use previous data), and so on. You can read more about the <b>WPA3 Security Standard for Wi-Fi networks, which has been introduced<\/b>.<\/p>\n<h2>WPA2 is still secure<\/h2>\n<p>Currently, Wi-Fi networks often use WPA2, and it is worth noting that this standard remains highly secure. As we explained, most attacks and damage occur in large enterprise networks, posing little to no Problem for home networks. This is because WPA2 has undergone constant updates over the years.<\/p>\n<h3><strong>WPA2 vs. WPA3: Key Differences<\/strong><\/h3>\n<p>The table below summarizes the significant differences between <strong>WPA2<\/strong>\u00a0and\u00a0<strong>WPA3<\/strong> in terms of Security, encryption, and compatibility.<\/p>\n<div class=\"markdown-table-wrapper\">\n<table>\n<thead>\n<tr>\n<th><strong>Feature<\/strong><\/th>\n<th><strong>WPA2<\/strong><\/th>\n<th><strong>WPA3<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Encryption<\/strong><\/td>\n<td>AES-128-bit<\/td>\n<td>AES-192-bit (stronger encryption)<\/td>\n<\/tr>\n<tr>\n<td><strong>Key Exchange<\/strong><\/td>\n<td>4-way handshake (vulnerable to KRACK)<\/td>\n<td>Dragonfly handshake (SAE, more secure)<\/td>\n<\/tr>\n<tr>\n<td><strong>Authentication<\/strong><\/td>\n<td>Pre-Shared Key (PSK)<\/td>\n<td>Simultaneous Authentication of Equals (SAE)<\/td>\n<\/tr>\n<tr>\n<td><strong>Password Security<\/strong><\/td>\n<td>Vulnerable to offline dictionary attacks<\/td>\n<td>Resistant to offline attacks<\/td>\n<\/tr>\n<tr>\n<td><strong>Forward Secrecy<\/strong><\/td>\n<td>Not supported<\/td>\n<td>Enabled (prevents decryption of past sessions)<\/td>\n<\/tr>\n<tr>\n<td><strong>Side-Channel Protection<\/strong><\/td>\n<td>No<\/td>\n<td>Protects against cache-based attacks<\/td>\n<\/tr>\n<tr>\n<td><strong>Compatibility<\/strong><\/td>\n<td>Widely supported<\/td>\n<td>Limited to newer devices<\/td>\n<\/tr>\n<tr>\n<td><strong>Transition Mode<\/strong><\/td>\n<td>Compatible with WPA<\/td>\n<td>Compatible with WPA2<\/td>\n<\/tr>\n<tr>\n<td><strong>Adoption<\/strong><\/td>\n<td>Industry standard<\/td>\n<td>Gradually being adopted<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3><strong>WPA2-Personal vs. WPA3-Personal<\/strong><\/h3>\n<ol start=\"1\">\n<li><strong>Security<\/strong>\n<ul>\n<li><strong>WPA2-Personal:<\/strong>\u00a0Uses TKIP or AES encryption.
