Download Latest Snort Rules

Kita dapat men-download Snort Rules yang terakhir. Kita perlu membuat login di snort.org Kemudian Sign-In untuk download rules. Setelah rules berhasil di download, copy ke ke /usr/local/src.

Kemudian lakukan: 

cd /usr/local/src
tar zxvf community-rules.tar.gz -C /usr/local/snort
tar zxvf snortrules-snapshot-2962.tar.gz -C /usr/local/snort
tar zxvf snortrules-snapshot-2976.tar.gz -C /usr/local/snort
tar zxvf snortrules-snapshot-2980.tar.gz -C /usr/local/snort
mkdir -p /usr/local/snort/lib/snort_dynamicrules
cp /usr/local/snort/so_rules/precompiled/Ubuntu-12-04/x86-64/2.9.8.0/* /usr/local/snort/lib/snort_dynamicrules/
touch /usr/local/snort/rules/white_list.rules
touch /usr/local/snort/rules/black_list.rules
ldconfig -v

Edit file konfigurasi snort.conf 

vi /usr/local/snort/etc/snort.conf

Set nilai di bawah ini 

var WHITE_LIST_PATH /usr/local/snort/rules
var BLACK_LIST_PATH /usr/local/snort/rules

dynamicpreprocessor directory /usr/local/snort/lib/snort_dynamicpreprocessor/

Download & Install Barnyard2

Barnyard2 akan memperbaiki efisiensi Snort dengan cara mengurangi beban dari engine deteksi utama. Barnyard2 akan membaca file keluaran logging snort dan memasukannya ke database. Jika database tidak tersedia, Barnyard2 akan memasukan data saat database kembali online sehingga tidak ada alert yang akan hilang.

Instalasi barnyard2, 

cd /usr/local/src
git clone  http://github.com/firnsy/barnyard2.git barnyard2
cd barnyard2
autoreconf -fvi -I ./m4
./configure -with-mysql -with-mysql-libraries=/usr/lib/x86_64-linux-gnu
make
make install
cp etc/barnyard2.conf /usr/local/snort/etc
mkdir /var/log/barnyard2
chmod 666 /var/log/barnyard2
touch /var/log/snort/barnyard2.waldo
chown snort.snort /var/log/snort/barnyard2.waldo

Buat database untuk snort yang akan digunakan Barnyard untuk penyimpanan, 

mysql -u root -p123456

create database snortdb;
grant create, insert, select, delete, update on snortdb.* to 'snortuser'@'localhost' identified by '3ngin33r';
flush privileges;
quit;

Buat Snort DB

mysql -u root -p123456 -D snortdb < /usr/local/src/barnyard2/schemas/create_mysql

Modifikasi file konfigurasi Barnyard2 dengan perintah berikut: 

vi /usr/local/snort/etc/barnyard2.conf

Set nilai berikut 

config reference_file: /usr/local/snort/etc/reference.config
config classification_file: /usr/local/snort/etc/classification.config
config gen_file: /usr/local/snort/etc/gen-msg.map
config sid_file: /usr/local/snort/etc/sid-msg.map
config hostname: localhost
config interface: eth0

output database: log, mysql, dbname=snortdb user=snortuser password=3ngin33r host=localhost

Ubah konfigurasi snort untuk Barnyard2

cp /usr/local/snort/snort-2.9.8.0/etc/gen-msg.map /usr/local/snort/etc/

Test Snort

/usr/local/snort/bin/snort -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth0


Akan keluar kira-kira

Harus keluar kata-kata 

“Commencing packet processing”

ini menandakan Snort telah di instalasi dan di konfigurasi dengan benar.

Auto Start

Agar Snort berjalan secara automatis, Tambahkan pada rc.local sebelum "exit" 

vi /etc/rc.local

isi 

ifconfig eth0 up

/usr/local/snort/bin/snort -D -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth0
/usr/local/bin/barnyard2 -c /usr/local/snort/etc/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard2.waldo -D
