checkpkgaudit 0.7.2

Check FreeBSD pkg audit Nagios|Icinga|shinken|etc plugin.

usage

This check runs pkg audit over your host and its running jails

sample outputs :

  • Ok

    CHECKPKGAUDIT OK - 0 vulnerabilities found ! | 'host.domain.tld'=0;;@1:;0 http=0;;@1:;0 masterdns=0;;@1:;0 ns0=0;;@1:;0 ns1=0;;@1:;0 ns2=0;;@1:;0 smtp=0;;@1:;0
    
  • Critical

    Critical state is reached with first vulnerable pkg. No warning, no configurable threasold, why waiting 2 or more vulnerabilities ?

    We are talking about security vulnerabilities !

    Of course, the plugin sum all the vulnerabilities and details each host|jail concerned

    CHECKPKGAUDIT CRITICAL - found 2 vulnerable(s) pkg(s) in : ns2, ns3 | 'host.domain.tld'=0;;@1:;0 http=0;;@1:;0 masterdns=0;;@1:;0 ns0=0;;@1:;0 ns1=0;;@1:;0 ns2=1;;@1:;0 ns3=1;;@1:;0 smtp=0;;@1:;0
    

    Notice that summary returns the total amount problems :

    found 2 vulnerable(s) pkg(s) in : ns2, ns3 but performance data is detailled by host|jail

  • Unknown

    if an error occured during pkg audit, the plugin raises a check error, which returns an UNKNOWN state.

    typically UNKNOWN causes

    • pkg audit -F has not been runned on host or a jail
    CHECKPKGAUDIT UNKNOWN - jailname  Try running 'pkg audit -F' first | 'host.domain.tld'=0;;@1:;0 http=0;;@1:;0 masterdns=0;;@1:;0 ns0=0;;@1:;0 ns1=0;;@1:;0 ns2=0;;@1:;0 smtp=0;;@1:;0
    
    • pkg -j jailname audit runned as a non sudoer user
    CHECKPKGAUDIT UNKNOWN - jailname pkg: jail_attach(jailname): Operation not permitted | 'host.domain.tld'=0;;@1:;0
    

    If you have running jails, sudo is your friend to run this plugin with an unprivileged user. A sample config here

    icinga ALL = NOPASSWD: /usr/local/bin/check_pkgaudit
    

Install

checkpkgaudit can be installed via either easy_install or pip .

Within or not a virtualenv:

easy_install checkpkgaudit
# or
pip install checkpkgaudit

check_pkgaudit is located at /usr/local/bin/check_pkgaudit

Warning

SSL certificate error

If you encountered an ssl certificate error with easy_install, you probably need to install the Root certificate bundle from the Mozilla Project:

pkg install -y ca_root_nss
ln -s /usr/local/share/certs/ca-root-nss.crt /etc/ssl/cert.pem

Nagios|icinga like configuration

check_pkgaudit could be called localy or remotely via check_by_ssh or NRPE.

check_by_ssh

here a sample definition to check remotely by ssh

Command definition

define command{
    command_name    check_ssh_pkgaudit
    command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -i /var/spool/icinga/.ssh/id_rsa -C "sudo /usr/local/bin/check_pkgaudit"
}

the service itself

define service{
    use                     my-service
    host_name               hostname
    service_description     pkg audit
    check_command           check_ssh_pkgaudit!
}

icinga2 command

object CheckCommand "pkgaudit" {
import "plugin-check-command"
import "ipv4-or-ipv6"
command = [ PluginDir + "/check_by_ssh" ]
arguments = {
    "-H" = "$address$"
    "-i" = "$ssh_id$"
    "-p" = "$ssh_port$"
    "-C" = "$ssh_command$"
    }
vars.address = "$check_address$"
vars.ssh_id = "/var/spool/icinga/.ssh/id_rsa"
vars.ssh_port = "$vars.ssh_port$"
vars.ssh_command = "sudo /usr/local/bin/check_pkgaudit"
}

icinga2 service

apply Service "pkgaudit" {
    check_command = "pkgaudit"
    assign where host.name == "hostname"
}

NRPE

add this line to /usr/local/etc/nrpe.cfg

...
command[check_pkgaudit]=/usr/local/bin/check_pkgaudit
...

nagios command definition

define command{
    command_name    check_nrpe_pkgaudit
    command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_pkgaudit
}

the service itself

define service{
    use                     my-service
    host_name               hostname
    service_description     pkg audit
    check_command           check_nrpe_pkgaudit
}
