Bạn nên cân nhắc dùng barnyard2-1.10beta2 (1.9 chưa hỗ trợ)

unified2
snort ----------> barnyard2 ------> snortsam

Sau này có thể upgrade từng phần dễ dàng hơn là cứ phải patch snort 

Bạn có thể hướng dẫn cách làm được không, tìm trên mạng chưa thấy bài hướng dẫn cách làm trên
----solved---
Hiện tại mình làm mô hình
Code:
snort -> barnyard2 2.11 |-> mysql -> base
|-> snortSAM -> iptables

như mô hình trên thì phải làm thế nào ? Mình tìm trên mạng mãi mà chưa thấy bài nào hưỡng dẫn mô hình trên.
Ai hướng dẫn mình cách làm được không ?

Cảm ơn nhiều smilie
Hiện tại snort test rule local.rules với
Code:
#alert icmp any any -> any any (msg:"ICMP Packet"; sid:477; rev:3;)

thì snort có cảnh báo, và update lên database qua barnyard.
Nhưng các rule còn lại mình down từ snor.org và copy vào thư mục /etc/snort
Code:
[root@localhost ~]# ls /etc/snort/
attribute_table.dtd Makefile reference.config threshold.conf
barnyard2.conf Makefile.am rules unicode.map
classification.config Makefile.in snort.conf
gen-msg.map preproc_rules so_rules

ví dụ như /etc/snort/rules/scan.rules , mình đã uncomment tất cả các alert trong file này nhưng snort không thấy thông báo gì.
Code:
var RULE_PATH /etc/snort/rules
var SO_RULE_PATH /etc/snort/so_rules
var PREPROC_RULE_PATH /etc/snort/preproc_rules
include $RULE_PATH/scan.rules

mình scan = nmap tới eth0 của snort.
máy snort đã stop service iptables
start snort = lệnh Code:
/usr/local/bin/snort -D -u snort -g snort -c /etc/snort/snort.conf -i eth0


Cho mình hỏi luôn, những rule thuộc so_rules toàn là file nhị phân có đuối là .so
Muốn sử dụng các rule này thì phải làm thế nào ?

Mong mọi người giúp đỡ !
Thanks smilie

Tốt nhất là lần sau bạn nên làm theo hướng dẫn theo tài liệu đi kèm. http://www.snort.org/assets/159/Snort_2.9.1_CentOS_5.pdf

Có thể vấn đề của bạn là ở đây:
Code:
database: [SynchronizeEventId()]: Problems executing [SELECT MAX(cid) FROM data WHERE sid='1';]
database: [SynchronizeEventId()]: Problems executing [SELECT MAX(cid) FROM event WHERE sid='1';]
database: [SynchronizeEventId()]: Problems executing [SELECT MAX(cid) FROM icmphdr WHERE sid='1';]

database: [SynchronizeEventId()]: Problems executing [SELECT MAX(cid) FROM tcphdr WHERE sid='1';]
database: [SynchronizeEventId()]: Problems executing [SELECT MAX(cid) FROM udphdr WHERE sid='1';]


Bạn vui lòng kiểm tra lại thư mục /var/log/barnyard2 có những file nào?
Code:
ls -la /var/log/barnyard2


Kiểm tra lại xem database của Snort đã được tạo hay chưa?
Code:
$mysql -u snort -p
mysql> SHOW DATABASES;
mysql> use snort;
mysql> SHOW TABLES;


Các file cấu hình của bạn mình không thấy vấn đề gì hết. Không rõ bạn cài đặt và cấu hình barnyard bằng cách nào?

Mình cài barnyard2 theo cách ở đây

Nếu sửa không được chắc phải làm lại từ đầu theo file pdf đó quá. smilie
bị double, xoá bớt 1 bài.

Bạn cài đặt snort theo hướng dẫn nào?
Bạn đã tạo database cho snort trên mysql chưa?

Bạn tử test lại bằng cách scan với nmap thử xem kết quả có sự khác biệt hay không smilie 

Mình cài theo hướng dẫn này http://quantrimang.edu.vn/he-thong/he-thong-mang-lan/trien-khai-snort-tren-centos.htm
do bản mới 2.9.4.1 không output trực tiếp lên database mà phải thông qua barnyard2 2 nên trong file config của snort mình edit lại là output unified2
và barnyard2 là input unified2
đã thử = nmap luôn, file log của snort có ghi, nhưng barnyard vẫn báo read 0 records
để up 2 file conf của snort với barnyard2 cho mọi người dễ giúp mình.

# 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.

# 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: localhost
config interface: eth1
# enable printing of the interface name when alerting.
#
#config alert_with_interface_name

# ----------------------------------------------------------------------------
#
# 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)
#
# Examples:

# 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)
# payload_encoding - (default: hex) support hex/ascii/base64 for log_syslog_full using operation_mode complete only.

Theo thông tin của bồ đưa ra thì Snort đã xử lý và cảnh báo các xâm nhập (gói ping) và theo output từ Barnyard2 thì Barnyard2 cũng đã đọc (đoạn màu đỏ) các log của Snort lên.

Nhưng cho mình hỏi là bồ "ping" trước hay sau khi bật Snort và bật Barnyard2 lên. Theo như post của bồ thì bồ chạy Snort xong, ping xong, bồ mới chạy Barnyard2 phải ko?

P/S: Dạo này HVA khó truy cập quá, chỉnh sửa rối lung tung :'( 

start snort, start barnyard2 rồi mình ping -t, liên tục.
khi mình xem file snort.log.xxx thì có ghi cảnh báo của snort, nhưng theo output của barnyard2 thì lại là read 0 records, và không có update database. Không biết thế nào luôn.
Mình thử start barnyard lại 1 lần nữa thì cũng vậy, read 0 records smilie
Không hiểu sao trong file snort.log.xxx có ghi mà sao barnyard read 0 records. haizz

Vấn đề là Snort đã bắt được cảnh báo nào chưa. Bồ kiểm tra trong thư mục /var/log/snort xem có file mới được tạo ra sau khi start Snort ko? Nếu ko, Snort của bạn chưa cảnh báo được -> thì lấy đâu ra database để đọc lên.

Bồ có thử xâm nhập; để Snort cảnh báo hay chưa? trong local.rules bồ có để rule nào để Snort cảnh báo hay chưa?

Ngoài ra khi start Barnyard2 bồ bỏ option -D đi để xem các output khi start thế nào (nếu được bồ chụp lại output của Barnyard2 dùm) còn Snort bồ dùng option -i <ethX> để chỉ định card mạng mà bồ định bắt gói tin.
 


Nó đã có ghi vào file log là có máy ping.
Start snort : snort -c /etc/snort/snort.conf -u snort -g snort -A console

Start Barryard2 có xuất hiện ra thông báo lỗi gì ko?

Thử kiểm tra lại một số thứ sau:

1. Khi build Baryard có tuỳ chọn --with-mysql chưa? đã tạo file barnyard2.waldo chưa? quyền cho các thư mục log ntn?


2. câu lệnh start Barnyard2 theo mình nhớ thì phải là -d /var/log/snort trỏ đến chỗ snort chứa log chứ? 


Khi build có --with-mysql, đã tạo file barnyard.waldo, đã chmod -R 777 cho folder /var/log/snort
start đã sửa lại nhưng database vẫn không chịu update, table event vẫn trống trơn, không biết sao luôn. haizz
Hình chụp:
Đây là thông tin file snort.log.xxx
https://docs.google.com/file/d/0B7DI6ZtmiK_dVDZ2M2llekFVLUE/edit?usp=sharing&pli=1

Cảm ơn, mong mọi người giúp mình tiếp.
Mọi người giúp mình, hiện tại mình đã config snort chạy ok, test bằng
snort -c /etc/snort/snort.conf -A console  

có xuất alert ra màn hình, file log có luôn.
nhưng cái baryard2 không chịu update database.
trong file config của snort mình đã set
output unified2: filename snort.log,limit 128 

trong file config của baryard2 thì mình sửa lại như thế này
Code:
output database: log, mysql, user=snort password=snortpass dbname=snort host=localhost
input unified2
config waldo_file: /var/log/snort/barnyard2.waldo
enable daemon mode
config hostname: localhost
config interface: eth1
config logdir: /var/log/barnyard2

user snort login mysql mình thường. grant all privileges rồi.
start snort : snort -c /etc/snort/snort.conf -A console
start baryard2: barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/ -f snort.log -w /etc/snort/barnyard2.waldo -u snort -g snort -D 


Mọi người giúp với, cảm ơn :)
