    Security Question: Is WPA2/WPA Personal Secure?


    Hi all,

    Sorry to be asking such a basic question, but this is related to my network's security so I thought it was important enough to ask about.

    I just checked and my "Security Mode" is set to "WPA2 Personal".

    The WiFi Network is 2.4Ghz.


    Can someone please help me?

    Thank you!

    EDIT:

    I changed the security mode on the wifi router to "WPA2 Personal".

    WPA2 Personal is the usual security mode for basic networks (using a pre-shared password).

    With WPA2 there are 2 supported encryption protocols: WPA2-TKIP is insecure and deprecated but some routers may still allow it for backwards compatibility with very old devices. WPA2-AES (aka WPA2-CCMP) is the preferred encryption method.

    While not perfectly secure, as there have been a few flaws found in its 14-year lifespan, WPA2 is still the best we have for now. If you have further security needs then use a VPN.

    Wi-Fi Security: Should You Use WPA2-AES, WPA2-TKIP, or Both? has more detailed explanations.

    My Wireless Access Point is now set to WPA2-PSK(AES) in recent years, which has been upped from WPA2-PSK(AES)+WPA-PSK(TKIP).
    The WPA-PSK(TKIP) was kept for compatibility for older stuff which has now been replaced.

    Both security options have been cracked. However you just use the highest level that is compatible with your hardware.

    Some manufacturers use slightly different terms, which is confusing, WPA2 Personal is probably the same as WPA2-PSK(AES) for recent kit. The detailed specs should tell you.

    As long as you use 63 characters long ASCII password, you should be fine.

    I have a massive migraine after thinking of trying to type that password into my iPhone, iPad, and IoT devices. :O

    The KRACK attack cares not for the length of your password.

    That is just scareware, if you are connecting to encrypted webpages (https), you are still protected. Anyone can eavesdrop to your connection along the way, not just via wifi, but SSL connection makes sure, it stays encrypted.

    Around 25% of web traffic is still not using HTTPS. So there is still value in having layered protection.

    Because they do not need it, only Google is forcing them to get SSL, but it only helps malware.
    I use the same login and password (mine is Password123) on them, so whatever. :)
