       rapolicy - compare a argus(8) data file/stream against a Cisco Access Control List.

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
