OpenVAS configuration

OpenVAS http://openvas.org/ is an open-source security scanner. The instructions below are concerning how to configure the application within Kali Linux.

The following commands are used once Kali Linux is installed and updated.

apt-get install openvas
openvas-setup
openvas-start
https://127.0.0.1:9392

Once the initial configuration is completed, a default initial password should be displayed. Start the required services and log in via the web interface to set a new password value under Administration -> Users. The default user name is admin.

Log into the web interface of the OpenVAS service and use the Feed Status menu option under Extras tab to verify the local databases are current.

To update the NVT feed via a terminal session, use the command greenbone-nvt-sync. The commands to update the other databases would be greenbone-scapdata-sync and greenbone-certdata-sync.

$store.Open("ReadOnly")
$store.certificates | select ThumbPrint,FriendlyName,NotAfter
