I have created the following video on youtube a few months ago and thought about embedding the video here as well. It is about configuring the Cisco ASA in order to install the ASDM image (Adaptive Security Device Manager) and hence be able to manage the device with the graphical ASDM GUI. The video shows also how to enable SSH access to the device, how to restrict access to a management network etc.
An out-of-the-box Cisco ASA device is not fully ready to be managed by the GUI interface (ASDM). There is an initial configuration required to enable ASDM access to the firewall.
I know the above task in pretty basic but I hope it will help a few people that are just starting out with ASA firewalls.
