WPA2WPA3suojaukset

WPA2WPA3suojaukset refers to the configuration settings that enable Wi‑Fi Protected Access 2 (WPA2) and Wi‑Fi Protected Access 3 (WPA3) on wireless networks. These encryption standards are defined by the Wi‑Fi Alliance and aim to provide robust security for data transmitted over Wi‑Fi. WPA2, introduced in 2004, uses the AES encryption algorithm and a pre‑shared key or enterprise authentication to protect traffic. In 2018 the Wi‑Fi Alliance launched WPA3, which builds on WPA2 by adding forward secrecy, a stronger password‑based authentication protocol (Simultaneous Authentication of Equals), and improved protection against offline password‑guessing attacks.

Typical network devices that support WPA3 include modern routers, access points, and client devices such as smartphones, tablets, and laptops. When configuring a network, administrators can choose WPA2‑Personal, WPA3‑Personal, or WPA3‑Enterprise. A mixed mode is also available, allowing devices that only support WPA2 to connect while newer devices can use WPA3. The mixed mode approach ensures backward compatibility during a transition period.

For optimal security, it is recommended to enable WPA3 when all client devices support it and to use a strong, unique passphrase of at least 12 characters for WPA3‑Personal. Network administrators should also ensure that the WPA3‑Enterprise deployment utilizes a properly configured RADIUS server and that device firmware is kept up to date. Regularly reviewing wireless logs and performing penetration tests can further verify that the WPA2WPA3suojaukset provide the intended level of protection.
