Wi-Fi deauthentication attack

CybersalCybersal Member Posts: 10
A Wi-Fi deauthentication attack is a type of denial-of-service attack that targets communication between a user and a Wi-Fi wireless access point.
If someone is trying to deauthentice one of my devices on the network, will my Fingbox be able to let me know?
I tested this on my network and there is no indication that anything has happened or red flags.

    Fingbox is detecting de-authentication flood attacks through its WiFi Intrusion Protection feature. 
    Do you have your access points protected with WiFi intrusion? 
    And did you receive any alert for another access point?
    Could you tell us more about how you tested this? (Don't have to give instructions about how to do this attack - but anymore info on if another access point was used would be helpful.)

    Hi ,I do see see that it protects against this attack, but how does it warn you?

    I used Kali Linux and wifite to deauth.

    I can try it again when I have time and look to see if the Fingbox warns me or give me any indication.

    Hi @Cybersal
    To get the alerts for the attack, Can you please try to pass the minimum threshold and see if the Fingbox is able to provide you with an alert or not.

    In order to avoid false alarms, there are minimum thresholds to raise an alarm:
    - the minimum duration of attack: 10-30 seconds
    - minimum deauth packets per second: 30/sec
    Our Engineers have tested deauth attack with aircrak several times and the attack was detected and was reported within 5 minutes with mail and event in fingbox logs.

    Hi Robin

    Thanks for the feedback. Can you tell me where to set the minimum threshold. I went through the Fing app settings and cannot find it.

    Hi @Cybersal
    There is no setting on the Fing app to set the minimum threshold. I shared the minimum threshold already set by default for any attacks like deauth attacks to be notified. The device from which you are trying to send De-auth packets needs to pass this minimum threshold so that Fingbox can alert you for the attack.
