SYNOPSIS

       rapolicy -r argus-file [ra options]

DESCRIPTION

       Rapolicy reads argus data from an argus-file list, and tests the argus data stream  against a Cisco access control list configuration file,
       printing out records that represent activity that would violate the policy.  Rapolicy can be used to indicate access control violations, as
       well as test new access control definitions prior to installing them in a router.

OPTIONS

       Rapolicy, like all ra based clients, supports a large number of options.  Options that have specific meaning to rapolicy are:

	  -f <Cisco ACL file> Print records that violate the policy.
	  -D 0 (default)      Print records that violate the policy.
	  -D 1		      Print records and the violated ruleset.
	  -D 2		      Print all records and the ruleset that matched.

       See ra(1) for a complete description of ra options.

EXAMPLE INVOCATION

       rapolicy -r argus.file

CISCO ACL SYNTAX

       There  does  not  seem to be authoritative Cisco-ACL-Documentation, nor ACL syntax standardization.  Because Cisco has been know to improve
       its ACL rules syntax, rapolicy is known to work with Cisco ACL router defintions up to July, 2002.

       A Cisco ACL configuration file consists of a collection of any number of ACL statements, each on a separte line.   The  syntax  of  an  ACL
       statement is:

	  ACL	     = "access-list" ID ACTION PROTOCOL SRC DST NOTIFICATION

	  ID	     = Number
	  ACTION     = permit | deny
	  PROTO      = protocol name | protocol number

	  SRC | DST  = ADDRESS [PORTMATCH]

	  ADDRESS    = any | host HOSTADDR | HOSTADDR HOSTMASK
	  HOSTADDR   = ipV4 address
	  HOSTMASK   = matching-mask

	  PORTMATCH  = PORTOP PORTNUM | range PORTRANGE
	  PORTOP     = eq | lt | gt | neq | established

	  PORTRANGE  =	PORTNUM PORTNUM
	  PORTNUM    =	TCP or UDP port value (unsigned decimal from 0 to 65535)

EXAMPLE CONFIGURATION

       This  example  Cisco Access Control List configuration is provided as an example only.  No effort has been made to verify that this example
       Access Control List enforces a useful access control policy of any kind.

       #allow www-traffic to webserver
       access-list 102 permit tcp any 193.174.13.99 0.0.0.0 eq 80

       #allow ftp control connection to server
       access-list 102 permit tcp any 193.174.13.99 0.0.0.0 eq 21

       #allow normal ftp
       access-list 102 permit tcp any 193.174.13.99 0.0.0.0 eq 20

       #allow ftp passive conncetions in portrange 10000 to 10500
       access-list 102 permit tcp any host 193.174.13.99 range 10000 10500

       #dummy example
       access-list 102 permit tcp host 193.174.13.1 eq 12345 host 193.174.13.2 range 12345 23456

       #deny the rest
       access-list 102 deny tcp any any

       #same thing in other words:
       access-list 102 deny tcp 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
