"Dahua devices with Build time before December 2019 use strong security
login mode by default, but in order to be compatible with the normal
login of early devices, some devices retain the weak security login
mode that users can control. If the user uses a weak security login
method, an attacker can monitor the device network to intercept
network packets to attack the device. So it is recommended that the
user disable this login method.

This plugin only works with Tenable.ot.
