cek 

apachectl -M | grep --color security

Install ModSecurity Core Rule Set (CRS)

Instalasi dari Github

Ubuntui 20.04 

cd ~
git clone https://github.com/SpiderLabs/owasp-modsecurity-crs.git

cd ~/owasp-modsecurity-crs
sudo mv crs-setup.conf.example /etc/modsecurity/crs-setup.conf
sudo mv rules/ /etc/modsecurity/

Versi lama 

rm -rf /usr/share/modsecurity-crs
apt-get install -y git
git clone https://github.com/SpiderLabs/owasp-modsecurity-crs.git /usr/share/modsecurity-crs
cp /usr/share/modsecurity-crs/crs-setup.conf.example /usr/share/modsecurity-crs/crs-setup.conf


Silahkan baca2 file crs-setup.conf kalau mau mengerti cara / proses deteksi. Ada bagian PARANOID :) ..

Setup ModSecurity CRS

mkdir -p /usr/share/modsecurity-crs/activated_rules/
cd /usr/share/modsecurity-crs
for f in `ls rules`; do sudo ln -s ../rules/$f activated_rules/$f; done

Konfigurasi

Edit modsecurity.conf agar 

mv /etc/modsecurity/modsecurity.conf-recommended /etc/modsecurity/modsecurity.conf
vi /etc/modsecurity/modsecurity.conf

Ubah 

SecRuleEngine DetectionOnly

menjadi 

SecRuleEngine On


Edit security2.conf 

vi /etc/apache2/mods-available/security2.conf

Tambahkan IncludeOptional /usr/share/modsecurity-crs/activated_rules/*.conf 

<IfModule security2_module>
        # Default Debian dir for modsecurity's persistent data
        SecDataDir /var/cache/modsecurity

        # Include all the *.conf files in /etc/modsecurity.
        # Keeping your local configuration in that directory
        # will allow for an easy upgrade of THIS file and
        # make your life easier
        IncludeOptional /etc/modsecurity/*.conf
        Include "/usr/share/modsecurity-crs/*.conf"
        Include "/usr/share/modsecurity-crs/activated_rules/*.conf"
</IfModule>

Reload Apache

Enable module 

a2enmod headers
a2enmod security2
service apache2 reload


Cara Disable module 

a2dismod headers
a2dismod security2
service apache2 reload

Test

Jika anda menginstalasi DVWA, bisa di lakukan test ke DVWA dengan kondisi module di enable / disable.

XSS

curl 'http://localhost/?q="><script>alert(1)</script>'

SQLi

curl "http://localhost/?q='1 OR 1=1"

Responds

Harusnya akan dapat kode kira-kira 

403 Forbidden

Cek Log

watch -n 2 "tail /var/log/apache2/modsec_audit.log"

atau 

tail -f /var/log/apache2/modsec_audit.log
