The aim for this key was to make wireless networks such as Wi-Fi as safe as wired communications.

It gives significant improvements in the level of security over that provided by previous versions.

WPA2: WPA2 or WPAv2 is the next update to the WPA sceme for providing Wi-Fi network security.

The first version of this is also known as WPA1 or WPAv1.

WPA: Wi-Fi Protected Access WPA is a software / firmware improvement over WEP.

Unfortunately it was easy to crack, and other systems are now more widely used.

WEP: WEP or Wired Equivalent Privacy was the first form of authentication used with Wi-Fi.

Since the introduction of Wi-Fi a variety of keys have been used: To achieve access, a key is generally required. Once detected, it is possible to try to connect to the access point, and the Wi-Fi authentication procedure starts. This allows prospective users to identify the access point and to try to connect to it. Wi-Fi access points advertise their presence by periodically sending out a beacon signal that contains the SSID. As the wireless signal can be picked up by non-authorised users, it is imperative to ensure that they cannot access the system.Įven users who legitimately gain access to a system could the try to hack other computers on the same hotspot. Wi-Fi security is of significant importance because very many people use it: at home, in the office and when they are on the move. It is defined under the IEEE stadnard 802.11i and security schemes like as WEP, WPA, WPA2 and WPA3 are widely mentioned, with keys or codes being provided for the various Wi-Fi hotspots in use. Wi-Fi network security is an issue of importance to all Wi-Fi users. Key Wi-Fi standards / variants: 802.11n 802.11ac 802.11ax Wi-Fi 6 802.11be Wi-Fi 7 Details of other standards variants

WPA3–Enterprise – offers 192-bit encryption, and it uses AAA/RADIUS authentication server.Īs more and more network vulnerabilities are being discovered, we should always plan our security measures and get one step ahead of the attackers.

WPA3-Personal mode – offers 128-bit encryption, and it uses WPA-PSK/pre-shared key.

WPA3 Uses Either of These Two WiFi Security Modes:

Instead of a four-way handshake authentication, SAE improves the security of initial key exchange and offers better protection against offline dictionary-based attacks. The key length for AES has increased.Īnother new feature of WPA3 is Simultaneous Authentication of Equals or SAE. 2018: WPA3 – still uses AES but replaced CCMP with the Galois/Counter Mode Protocol (GCMP). If you want to connect to a network that uses a pre-shared key, then you need to know the SSID and the pre-shared key.Ĥ. It also introduced Wi-Fi Protected Setup (WPS). For backward compatibility reasons, you can still use TKIP as a fallback mechanism for WPA clients.

2004: WPA2 – the most significant upgrade in WPA2 is that it uses AES-CCMP encryption instead of the old RC4 encryption. TKIP uses 256-bit keys instead of the 64 and 128-bit keys in WEP.ģ. 2003: Wi-Fi Protected Access (WPA) – this wireless security standard uses Temporal Key Integrity Protocol (TKIP), which recycled some items from WEP, and it still uses the RC4 algorithm.

The IEEE declared in 2004 that WEP had been deprecated as it failed to meet its security goals.Ģ. Therefore, we need to implement Wi-Fi security. The convenience of Wi-Fi networks also makes it easy for transmissions to be overheard and exploited by malicious users. But because a Malicious User is within the wireless range of the wireless access point, it could potentially gain access to the same confidential data. In our figure below, let’s consider that User1 is trying to send confidential data to User2. Unlike in wired networks, where data is transmitted through fiber and copper cables, the Wi-Fi network transmits data across the air in accordance with the transmitter’s antenna pattern, and it could reach any Wi-Fi-enabled devices that are within the range.

Having a Cisco wireless network makes it easier to bring new devices online, and it also provides flexible support to mobile end users. Wireless Access Points (WAP), or Access Points (AP), allow wireless devices to connect to both wireless and wired networks. Wi-Fi is an abridgement for Wireless Fidelity, a networking technology that connects computers and other network devices using radio waves.
