You are here : Comodo HackerGuardian > Internal Scanning
The Internal Scanning feature allows customers to run HackerGuardian vulnerability scans on computers located on a local area network (LAN). These computers are typically 'inside' the company's private network and are protected by a perimeter firewall or other network security device. In order to run an internal scan, the administrator must first install and configure the HackerGuardian internal scanning Agent on the local network.
Once installed and configured, this Agent will establish a secure connection to a HackerGuardian Access server which will in turn establish a secure communication channel (connection) to a HackerGuardian scanning server. The scanning server will then be able to connect to and run scans on the local computers located at the IP addresses that have been specified as Local Devices in HackerGuardian. The Agent software is available as an iso image (to create a Live CD), as files (to create a Live USB stick) or as files to run from a VM ware player. The scans can be run directly from the 'Overview' area of HackerGuardian interface after installation and configuration of the agent. (see 'How to install the Agent' , 'Configuring the Agent' and 'Using the Agent - Main Menu' for more details on set up and configuration of the agent. See 'Start Device Scanning' to learn how to run an internal scan once the agent has been installed.)
There are two main prerequisites to running an internal scan:
- The creation of a 'Local Device' as a target for the scans in the 'Device List' area of the HackerGuardian interface. Local Devices are defined by one or more IP addresses.
- The internal scanning Agent has been installed on your local network to communicate with the HackerGuardian scanning servers via VPN connection.
Once these two steps are complete, users can start an internal scan on the device by clicking the 'Start Scan' button in the 'Overview' area.
For creating local devices and to run scans on the local devices, switch to 'Device List' area of HackerGuardian. Click here for more details on the interface.
Note: The Internal Scanning feature allows you to create and edit local target devices and to manually run scans on selected devices. Unlike other, 'external', devices, 'LAN Devices' are defined using IP addresses only.

Configuring the Agent
To start the configuration, boot the device through the Live CD or the Live USB.
The agent starts building a list of block devices for storing the configuration files. The agent detects hard disks, USB memory drives and/or other available block devices containing with live file system (like FAT 12, FAT16, FAT 32, VFAT, ext2/ext3, XFS, reisrfs etc.) and proposes a list of valid devices for you to choose from. Select a device to store the configuration files.
The agent asks for a short description of the saved configuration. You can give a short name/description for the configuration (Max 40 characters)
The network configuration dialog appears to specify the network configuration settings. The available network adapters are detected and displayed as a list. Only one network adapter can be used at a time. Select the network adapter through which you want the scan to be performed and select OK.
The connection mode configuration dialog appears. The available choices are Static IP address and DHCP. Select the mode in which the device is connected.
In the next dialog, set the parameters for the selected connection (The agent detects the default parameters of the device and displays them. Only change the values you wish to change and select OK. Use up and down arrow keys and the tab key for navigation).
If you are satisfied with the above configurations, select 'Apply' in the next dialog.
The configuration will be saved. If you want to edit the settings before saving, select Modify. The Network configuration will be restarted. If you do not want to save the settings, select Do nothing. The configuration will not be saved and the network configuration will be restarted.
The main menu will be displayed on completion of the configuration. You can modify the configuration at any time through the options in the main menu.
Using the Agent - Main Menu
The Main Menu of the HackerGuardian VPN agent contains the following options
- HackerGuardian Agent

After successfully configuring the network adapter, the network state will appear green in the lower right corner of the screen. The network state will be displayed in black if any connection problems arise indicating that the network connection setting are to be reconfigured.
Select a Device for Session Profile
The storage device chosen previously for storing the configuration settings and the session profiles can be changed/configured by choosing this menu. Selecting this menu again starts building a list of available block devices for storing the configuration.
Select and configure a storage device to use as a permanent storage for Live CD runtime configuration files. This is useful when you plan to boot and run the Live CD more than once with the same network settings and other configurations and do not want to reconfigure every time. The agent detects hard disks, USB memory drives and/or other available block devices containing with live file system (like FAT 12, FAT16, FAT 32, VFAT, ext2/ext3, XFS, reisrfs etc.) and proposes a list of valid devices for you to choose from. The selected device will then be used to store the configuration files by creating a special directory. The stored configuration will be automatically detected and reused every time the scanning is run. You can cancel the device selection if you do not want to store the configuration files.
The Diagnostic Console is intended for advanced users.
The menu contains various tools to diagnose the problems if the agent is not running properly. The console can be opened any time as required and it will not interfere the agent's normal operation.
