NAME

       pads - Passive Asset Detection System

SYNOPSIS

       pads <DhUvV> <-c file > <-d file > <-g group > <-i interface > <-n network(s) > <-p file > <-r file > <-u file > <-w file > <expression>

DESCRIPTION

       PADS is a libpcap based detection engine used to passively detect network assets.  It is designed to complement IDS technology by providing
       context to IDS alerts.

       Goals:

       - Passive:  Records and identifies traffic seen on a network without
	 actively "scanning" a system.	 There will never be a packet sent from
	 the pads application.

       - Portable:  Has the ability to be placed easily on a remote system.
	 Does not require additional external libraries other than those
	 associated with libpcap.

       - Lightweight:  Logging is sent to a simple CSV file.  There is no need
	 for a database or other data repository installed on the local
	 machine.  All correlation is done outside of the pads program.

OPTIONS

       -h     Display help / usage information.

       -D     Run PADS in the background (daemon mode).

       -d file
	      Dump banner data into a libpcap formatted file.  This feature will dump the matched packet or the first 4 packets  of  an  unmatched
	      connection into a specified file.  This can be used to further identify a service and also aid with signature development.

	      Please  keep  in	mind  that  this  feature  must  be  compiled into the application in order to use it.	This can be done by adding
	      '--enable-banner-grab' to the 'configure' step.

       -g group
	      This switch allows you to specify a group that PADS will drop to after the libpcap interface has been initialized.

       -h     Display help

       -i interface
	      Specify an interface to be used.

       -n network list
	      Specify a set of networks to be monitored.  Only assets that exist within these networks will be recorded.  The networks	should	be
	      specified in the following format: 10.10.10.0/24,192.168.0.0/16 .

       -p pid file
	      This switch allows you to specify a PID file to be used in conjunction with daemon (-D) mode.

       -r file
	      Read packets from a libpcap formatted file.

       -u user
	      This switch allows you to specify a user that PADS will drop to after the libpcap interface has been initialized.

       -w file
	      Dump data into a file other than assets.csv.

	expression
	      selects which packets will be processed.	Please see  tcpdump(1) for details on the libpcap primitives.
