NAME

App::PaloAlto::PolicyVerify - Test firewall rules using log files.

VERSION

version 0.0.1

SYNOPSIS

This is the supporting module for the pa_policy_verify application.

DESCRIPTION

This module contains the methods used by the pa_policy_verify application. It takes in information allowing it to connect to a Palo Alto firewall, and a logfile containing flows - source/destination IP & ports, and a protocol.

It then runs each flow in the log against the security rulebase currently installed on the Palo Alto firewall and returns a result. The result contains:

Which rule the flow would have hit
The action the rule takes
The index of the rule.

The main use case is when migrating from a different firewall to the Palo Alto. It allows for the qualification of the migrated rulebase prior to the cutover of production flows.

METHODS

new

my $fw_tester = App::PaloAlto::PolicyVerify->new(
    uri => 'https://pa.localdomain',
    username => 'admin',
    password => 'redacted',
    insecure => 0,
    vr => 'default',
    vsys => 1,
    logfile => '/home/user/logs.csv',
    sepchar => ',',
    fields => '0,1,2,3,4'
);

Contructs the object. Each argument maps to a command line switch in pa_policy_verify. Please refer to its documentation for information and default values.

The only argument without a default is logfile.

sepchar

$fw_tester->sepchar(';');

Sets the separating character between the fields in the logfile.

logfile

$fw_tester->logfile('/home/user/logfile.csv');

Sets the logfile containing flow information that will be run against the firewall.

fields

$fw_tester->fields(
    src_ip => 3,
    dst_ip => 4,
    src_port => 8,
    dst_port => 9,
    protocol => 20
);

Sets the column number in the logfile where each of the 5-tuple flow information resides.

run

$fw_tester->run();

Runs the flows contained in the logfile against the firewall.
