NAME

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
