2012/12/11後記

升到 barnyard2-1.11 後在base又出現跟之前相同的情況
看不到特徵值的名稱
改了好多東西都沒辦法
而且目前找不到相關文件
改回之前的版本就正常barnyard2-1.9
算了 先改回來
另外
snort 2.9.4-1 一定要把 $SO_RULE_PATH打開
之前的版本預設都不用開
不然事件會都無法偵測且記錄
===========================================
自從12/6升到snort 2.9.4-1的版本後
資料庫的資料就異常的少
剛好今天在snort的blog發現
barnyard2有更新版本(新官網)
看來這個blog的訊息還滿多的(已訂rss)
所以來升級一下看看狀況會不會改善
先備份 /usr/bin/barnyard2及 /etc/barnyard2/barnyard2.conf

升級步驟如下
解壓source後進到目錄

autogen.sh


./configure --bindir=/usr/bin --sysconfdir=/etc/barnyard2 --with-mysql

make && make install

再依照原本的barnyard2.conf改一下

========barnyard2.conf===============


#
#  Barnyard2 example configuration file
#

#
# This file contains a sample barnyard2 configuration.
# You can take the following steps to create your own custom configuration:
#
#   1) Configure the variable declarations
#   2) Setup the input plugins
#   3) Setup the output plugins
#

#
# Step 1: configure the variable declarations
#

# in order to keep from having a commandline that uses every letter in the
# alphabet most configuration options are set here.

# use UTC for timestamps
#
#config utc

# set the appropriate paths to the file(s) your Snort process is using.
#
config reference_file:      /etc/snort/rule/etc/reference.config
config classification_file: /etc/snort/rule/etc/classification.config
config gen_file:            /etc/snort/rule/etc/gen-msg.map
config sid_file:            /etc/snort/rule/etc/sid-msg.map

# Set the event cache size to defined max value before recycling of event occur.
#
#
#config event_cache_size: 4096

# define dedicated references similar to that of snort.
#
#config reference: mybugs http://www.mybugs.com/?s=

# define explicit classifications similar to that of snort.
#
#config classification: shortname, short description, priority

# set the directory for any output logging
#
#config logdir: /tmp

# to ensure that any plugins requiring some level of uniqueness in their output
# the alert_with_interface_name, interface and hostname directives are provided.
# An example of usage would be to configure them to the values of the associated
# snort process whose unified files you are reading.
#
# Example:
#   For a snort process as follows:
#     snort -i eth0 -c /etc/snort.conf
#
#   Typical options would be:
#     config hostname:  thor
#     config interface: eth0
#     config alert_with_interface_name
#
#config hostname:   thor
#config interface:  eth0
config hostname:   localhost
config interface:  eth1

# enable printing of the interface name when alerting.
#
#config alert_with_interface_name

# at times snort will alert on a packet within a stream and dump that stream to
# the unified output. barnyard2 can generate output on each packet of that
# stream or the first packet only.
#
#config alert_on_each_packet_in_stream

# enable daemon mode
#
#config daemon

# make barnyard2 process chroot to directory after initialisation.
#
#config chroot: /var/spool/barnyard2

# specifiy the group or GID for barnyard2 to run as after initialisation.
#
#config set_gid: 999

# specifiy the user or UID for barnyard2 to run as after initialisation.
#
#config set_uid: 999

# specify the directory for the barnyard2 PID file.
#
#config pidpath: /var/run/by2.pid

# enable decoding of the data link (or second level headers).
#
#config decode_data_link

# dump the application data
#
#config dump_payload

# dump the application data as chars only
#
#config dump_chars_only

# enable verbose dumping of payload information in log style output plugins.
#
#config dump_payload_verbose

# enable obfuscation of logged IP addresses.
#
#config obfuscate

# enable the year being shown in timestamps
#
#config show_year

# set the umask for all files created by the barnyard2 process (eg. log files).
#
#config umask: 066

# enable verbose logging
#
#config verbose

# quiet down some of the output
#
#config quiet

# define the full waldo filepath.
#
#config waldo_file: /tmp/waldo

# specificy the maximum length of the MPLS label chain
#
#config max_mpls_labelchain_len: 64

# specify the protocol (ie ipv4, ipv6, ethernet) that is encapsulated by MPLS.
#
#config mpls_payload_type: ipv4

# set the reference network or homenet which is predominantly used by the
# log_ascii plugin.
#
#config reference_net: 192.168.0.0/24

#
# CONTINOUS MODE
#

# set the archive directory for use with continous mode
#
#config archivedir: /tmp

# when in operating in continous mode, only process new records and ignore any
# existing unified files
#
#config process_new_records_only


#
# Step 2: setup the input plugins
#

# this is not hard, only unified2 is supported ;)
input unified2


#
# Step 3: setup the output plugins
#

# alert_cef
# ----------------------------------------------------------------------------
#
# Purpose:
#  This output module provides the abilty to output alert information to a
# remote network host as well as the local host using the open standard
# Common Event Format (CEF).
#
# Arguments: host=hostname[:port], severity facility
#            arguments should be comma delimited.

#                 this is only specific to WIN32 (and is not yet fully supported)
#   severity    - as defined in RFC 3164 (eg. LOG_WARN, LOG_INFO)
#   facility    - as defined in RFC 3164 (eg. LOG_AUTH, LOG_LOCAL0)
#
# Examples:
#   output alert_cef
#   output alert_cef: host=192.168.10.1
#   output alert_cef: host=sysserver.com:1001
#   output alert_cef: LOG_AUTH LOG_INFO
#

# alert_bro

#
# Arguments: hostname:port
#
# Examples:
#   output alert_bro: 127.0.0.1:47757

# alert_fast
# ----------------------------------------------------------------------------
# Purpose: Converts data to an approximation of Snort's "fast alert" mode.
#
# Arguments: file <file>, stdout
#            arguments should be comma delimited.
#   file - specifiy alert file
#   stdout - no alert file, just print to screen
#
# Examples:

#   output alert_fast: stdout
#
output alert_fast: stdout


# prelude: log to the Prelude Hybrid IDS system
# ----------------------------------------------------------------------------
#
# Purpose:
#  This output module provides logging to the Prelude Hybrid IDS system
#
# Arguments: profile=snort-profile
#   snort-profile   - name of the Prelude profile to use (default is snort).
#
# Snort priority to IDMEF severity mappings:
# high < medium < low < info
#
# These are the default mapped from classification.config:
# info   = 4
# low    = 3
# medium = 2
# high   = anything below medium
#
# Examples:
#   output alert_prelude
#   output alert_prelude: profile=snort-profile-name
#


# alert_syslog
# ----------------------------------------------------------------------------
#
# Purpose:
#  This output module provides the abilty to output alert information to local syslog
#
#   severity    - as defined in RFC 3164 (eg. LOG_WARN, LOG_INFO)
#   facility    - as defined in RFC 3164 (eg. LOG_AUTH, LOG_LOCAL0)

# syslog_full
#-------------------------------
# Available as both a log and alert output plugin.  Used to output data via TCP/UDP or LOCAL ie(syslog())
# Arguments:
#      sensor_name $sensor_name         - unique sensor name
#      server $server                   - server the device will report to
#      local                            - if defined, ignore all remote information and use syslog() to send message.
#      protocol $protocol               - protocol device will report over (tcp/udp)
#      port $port                       - destination port device will report to (default: 514)
#      delimiters $delimiters           - define a character that will delimit message sections ex:  "|", will use | as message section delimiters. (default: |)
#      separators $separators           - define field separator included in each message ex: " " ,  will use space as field separator.             (default: [:space:])
#      operation_mode $operaion_mode    - default | complete : default mode is compatible with default snort syslog message, complete prints more information such as the raw packet (hexed)
#      log_priority   $log_priority     - used by local option for syslog priority call. (man syslog(3) for supported options) (default: LOG_INFO)
#      log_facility  $log_facility      - used by local option for syslog facility call. (man syslog(3) for supported options) (default: LOG_USER)
