Konfigurasi Keamanan

Konfigurasi Keamanan XOOPS

Panduan komprehensif untuk mengamankan instalasi XOOPS Anda dari kerentanan web umum.

Daftar Periksa Keamanan

Sebelum meluncurkan situs Anda, terapkan langkah-langkah keamanan berikut:

Keamanan Sistem File

Izin Berkas

Izin file yang tepat sangat penting untuk keamanan.

Pedoman Izin

Jalur	Izin	Pemilik	Alasan
mainfile.php	644	akar	Berisi kredensial DB
*.file php	644	akar	Mencegah modifikasi yang tidak sah
Direktori	755	akar	Bolehkan membaca, cegah menulis
tembolok/	777	www-data	Server web harus menulis
templat_c/	777	www-data	template yang dikompilasi
unggahan/	777	www-data	Unggahan pengguna
var/	777	www-data	Data variabel
pasang/	Hapus	-	Hapus setelah instalasi
konfigurasi/	755	akar	Dapat dibaca, tidak dapat ditulis

Mengatur Skrip Izin

#!/bin/bash
XOOPS_PATH="/var/www/html/xoops"
WEB_USER="www-data"

# Set ownership
echo "Setting ownership..."
chown -R $WEB_USER:$WEB_USER $XOOPS_PATH

# Set restrictive default permissions
echo "Setting base permissions..."
find $XOOPS_PATH -type d -exec chmod 755 {} \;
find $XOOPS_PATH -type f -exec chmod 644 {} \;

# Make specific directories writable
echo "Setting writable directories..."
chmod 777 $XOOPS_PATH/cache
chmod 777 $XOOPS_PATH/templates_c
chmod 777 $XOOPS_PATH/uploads
chmod 777 $XOOPS_PATH/var

# Protect sensitive files
echo "Protecting sensitive files..."
chmod 644 $XOOPS_PATH/mainfile.php
chmod 444 $XOOPS_PATH/mainfile.php.dist  # If it exists (read-only)

# Verify permissions
echo "Verifying permissions..."
ls -la $XOOPS_PATH | grep -E "mainfile|cache|uploads|var|templates_c"

echo "Security hardening completed!"

Jalankan skrip:

chmod +x /usr/local/bin/xoops-secure.sh
/usr/local/bin/xoops-secure.sh

Hapus Folder Instalasi

KRITIS: Folder instalasi harus dihapus setelah instalasi!

# Option 1: Delete completely
rm -rf /var/www/html/xoops/install/

# Option 2: Rename and keep for reference
mv /var/www/html/xoops/install/ /var/www/html/xoops/install.bak/

# Verify removal
ls -la /var/www/html/xoops/ | grep install

Lindungi Direktori Sensitif

Buat file .htaccess untuk memblokir akses web ke folder sensitif:

Berkas: /var/www/html/xoops/var/.htaccess

<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar)$">
    Deny from all
</FilesMatch>

<IfModule mod_autoindex.c>
    Options -Indexes
</IfModule>

Berkas: /var/www/html/xoops/templates_c/.htaccess

<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar)$">
    Deny from all
</FilesMatch>

Options -Indexes

Berkas: /var/www/html/xoops/cache/.htaccess

Options -Indexes
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7)$">
    Deny from all
</FilesMatch>

Lindungi Direktori Upload

Cegah eksekusi skrip dalam unggahan:

Berkas: /var/www/html/xoops/uploads/.htaccess

# Prevent script execution
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7|phps|pht|phar|pl|py|jsp|asp|aspx|cgi|sh|bat|exe)$">
    Deny from all
</FilesMatch>

# Prevent directory listing
Options -Indexes

# Additional protection
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /xoops/uploads/

    # Block suspicious files
    RewriteCond %{REQUEST_URI} \.(php|phtml|php3|php4|php5|php6|php7)$ [NC]
    RewriteRule ^.*$ - [F,L]
</IfModule>

Konfigurasi SSL/HTTPS

Enkripsi semua lalu lintas antara pengguna dan server Anda.

Dapatkan Sertifikat SSL

Opsi 1: Sertifikat Gratis dari Let’s Encrypt

# Install Certbot
apt-get install certbot python3-certbot-apache

# Obtain certificate (auto-configures Apache)
certbot certonly --apache -d your-domain.com -d www.your-domain.com

# Verify certificate installed
ls /etc/letsencrypt/live/your-domain.com/

Opsi 2: Sertifikat SSL Komersial

Hubungi penyedia atau registrar SSL:

Beli sertifikat SSL
Verifikasi kepemilikan domain
Instal file sertifikat di server
Konfigurasikan server web

Konfigurasi Apache SSL

Buat host virtual HTTPS:

Berkas: /etc/apache2/sites-available/xoops-ssl.conf

<VirtualHost *:443>
    ServerName your-domain.com
    ServerAlias www.your-domain.com
    DocumentRoot /var/www/html/xoops

    # SSL Configuration
    SSLEngine on
    SSLProtocol TLSv1.2 TLSv1.3
    SSLCipherSuite HIGH:!aNULL:!MD5
    SSLCertificateFile /etc/letsencrypt/live/your-domain.com/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/your-domain.com/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/your-domain.com/chain.pem

    # Security Headers
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"
    Header always set X-Content-Type-Options "nosniff"
    Header always set X-Frame-Options "SAMEORIGIN"
    Header always set X-XSS-Protection "1; mode=block"
    Header always set Referrer-Policy "no-referrer-when-downgrade"
    Header always set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'"

    <Directory /var/www/html/xoops>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    # Restrict install folder
    <Directory /var/www/html/xoops/install>
        Deny from all
    </Directory>

    # Logging
    ErrorLog ${APACHE_LOG_DIR}/xoops_ssl_error.log
    CustomLog ${APACHE_LOG_DIR}/xoops_ssl_access.log combined
</VirtualHost>

# Redirect HTTP to HTTPS
<VirtualHost *:80>
    ServerName your-domain.com
    ServerAlias www.your-domain.com
    Redirect 301 / https://your-domain.com/
</VirtualHost>

Aktifkan konfigurasi:

# Enable SSL module
a2enmod ssl

# Enable site
a2ensite xoops-ssl

# Disable non-SSL site if exists
a2dissite 000-default

# Test configuration
apache2ctl configtest
# Should output: Syntax OK

# Restart Apache
systemctl restart apache2

Konfigurasi SSL Nginx

Berkas: /etc/nginx/sites-available/xoops

# HTTP to HTTPS redirect
server {
    listen 80;
    listen [::]:80;
    server_name your-domain.com www.your-domain.com;

    location / {
        return 301 https://$server_name$request_uri;
    }
}

# HTTPS server
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name your-domain.com www.your-domain.com;
    root /var/www/html/xoops;
    index index.php index.html;

    # SSL Certificate Configuration
    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;

    # Modern SSL Configuration
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;

    # HSTS Header
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

    # Security Headers
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header Referrer-Policy "no-referrer-when-downgrade" always;
    add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'" always;

    # Restrict install folder
    location ~ ^/(install|upgrade)/ {
        deny all;
    }

    # Deny access to sensitive files
    location ~ /\. {
        deny all;
    }

    # PHP-FPM back-end
    location ~ \.php$ {
        fastcgi_pass unix:/run/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    # Static files caching
    location ~* \.(js|css|png|jpg|gif|ico|svg)$ {
        expires 30d;
        add_header Cache-Control "public, immutable";
    }

    # URL rewriting
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    # Logging
    access_log /var/log/nginx/xoops_access.log;
    error_log /var/log/nginx/xoops_error.log;
}

Aktifkan konfigurasi:

ln -s /etc/nginx/sites-available/xoops /etc/nginx/sites-enabled/
nginx -t
systemctl restart nginx

Verifikasi Instalasi HTTPS

# Test SSL configuration
openssl s_client -connect your-domain.com:443 -tls1_2

# Check certificate validity
openssl x509 -in /etc/letsencrypt/live/your-domain.com/cert.pem -noout -text

# SSL/TLS test online
# https://www.ssllabs.com/ssltest/
# https://www.testssl.sh/

Perpanjangan Otomatis Mari Enkripsi Sertifikat

# Enable auto-renewal
systemctl enable certbot.timer
systemctl start certbot.timer

# Test renewal process
certbot renew --dry-run

# Manual renewal if needed
certbot renew --force-renewal

Keamanan Aplikasi Web

Melindungi Terhadap Injeksi SQL

XOOPS menggunakan kueri berparameter (aman secara default), tetapi selalu:

// UNSAFE - Never do this!
$query = "SELECT * FROM users WHERE name = '" . $_GET['name'] . "'";

// SAFE - Use prepared statements
$database = XoopsDatabaseFactory::getDatabaseConnection();
$sql = "SELECT * FROM " . $database->prefix('users') . " WHERE name = ?";
$result = $database->query($sql, array($_GET['name']));

Pencegahan Skrip Lintas Situs (XSS)

Selalu bersihkan masukan pengguna:

// UNSAFE
echo $_GET['user_input'];

// SAFE - Use XOOPS sanitization functions
echo htmlspecialchars($_GET['user_input'], ENT_QUOTES, 'UTF-8');

// Or use XOOPS functions
$text_sanitizer = new xoops_text_sanitizer();
echo $text_sanitizer->stripSlashesGPC($_GET['user_input']);

Pencegahan Pemalsuan Permintaan Lintas Situs (CSRF)

XOOPS menyertakan perlindungan token CSRF. Selalu sertakan token:

<!-- In forms -->
<form method="post">
    {xoops_token form=update}
    <input type="text" name="field">
    <input type="submit">
</form>

Nonaktifkan Eksekusi PHP di Folder Unggah

Cegah penyerang mengunggah dan mengeksekusi PHP:

# Create .htaccess in uploads folder
cat > /var/www/html/xoops/uploads/.htaccess << 'EOF'
<FilesMatch "\.(php|phtml|php3|php4|php5|php6|php7)$">
    Deny from all
</FilesMatch>
php_flag engine off
EOF

# Alternative: Disable execution globally in uploads
chmod 444 /var/www/html/xoops/uploads/  # Read-only

Header Keamanan

Konfigurasikan header keamanan HTTP penting:

# Strict-Transport-Security (HSTS)
# Forces HTTPS for 1 year
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

# X-Content-Type-Options
# Prevents MIME type sniffing
Header always set X-Content-Type-Options "nosniff"

# X-Frame-Options
# Prevents clickjacking attacks
Header always set X-Frame-Options "SAMEORIGIN"

# X-XSS-Protection
# Browser XSS protection
Header always set X-XSS-Protection "1; mode=block"

# Referrer-Policy
# Controls referrer information
Header always set Referrer-Policy "strict-origin-when-cross-origin"

# Content-Security-Policy
# Controls resource loading
Header always set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self'"

Keamanan Panel Admin

Ganti nama Folder Admin

Lindungi folder admin dengan mengganti namanya:

# Rename admin folder
mv /var/www/html/xoops/admin /var/www/html/xoops/myadmin123

# Update admin access URL
# Old: http://your-domain.com/xoops/admin/
# New: http://your-domain.com/xoops/myadmin123/

Konfigurasikan XOOPS untuk menggunakan folder yang diganti namanya:

Sunting mainfile.php:

// Change this line
define('XOOPS_ADMIN_PATH', '/var/www/html/xoops/myadmin123');

Daftar Putih IP untuk Admin

Batasi akses admin ke IP tertentu:

Berkas: /var/www/html/xoops/myadmin123/.htaccess

# Allow only specific IPs
<RequireAll>
    Require ip 192.168.1.100   # Your office IP
    Require ip 203.0.113.50    # Your home IP
    Deny from all
</RequireAll>

Atau dengan Apache 2.2:

Order Deny,Allow
Deny from all
Allow from 192.168.1.100 203.0.113.50

Kredensial Admin yang Kuat

Terapkan kata sandi yang kuat untuk administrator:1. Gunakan minimal 16 karakter 2. Campur huruf besar, huruf kecil, angka, simbol 3. Ganti password secara berkala (setiap 90 hari) 4. Gunakan pengelola kata sandi 5. Aktifkan otentikasi dua faktor jika tersedia

Pantau Aktivitas Admin

Aktifkan pencatatan login admin:

Panel Admin > Sistem > Preferensi > Pengaturan Pengguna

Log Admin Logins: Yes
Log Failed Login Attempts: Yes
Alert Email on Admin Login: Yes

Tinjau log secara teratur:

# Check database for login attempts
mysql -u xoops_user -p xoops_db << EOF
SELECT uid, uname, DATE_FROM_UNIXTIME(user_lastlogin) as last_login
FROM xoops_users WHERE uid = 1;
EOF

Perawatan Reguler

Perbarui XOOPS dan module

Selalu perbarui XOOPS dan semua module:

# Check for updates in admin panel
# Admin > Modules > Check for Updates

# Or via command line
cd /var/www/html/xoops
# Download and install latest version
# Follow upgrade guide

Pemindaian Keamanan Otomatis

#!/bin/bash
# Security audit script

# Check file permissions
echo "Checking file permissions..."
find /var/www/html/xoops -type f ! -perm 644 ! -name "*.htaccess" | head -10

# Check for suspicious files
echo "Checking for suspicious files..."
find /var/www/html/xoops -type f -name "*.php" -newer /var/www/html/xoops/install/ 2>/dev/null

# Check database for suspicious activity
echo "Checking for failed login attempts..."
mysql -u xoops_user -p xoops_db << EOF
SELECT count(*) as attempts FROM xoops_audittrail WHERE action LIKE '%login%' AND status = 0;
EOF

Pencadangan Reguler

Otomatiskan pencadangan harian:

#!/bin/bash
# Daily backup script

BACKUP_DIR="/backups/xoops"
RETENTION=30  # Keep 30 days

# Backup database
mysqldump -u xoops_user -p xoops_db | gzip > $BACKUP_DIR/db_$(date +%Y%m%d).sql.gz

# Backup files
tar -czf $BACKUP_DIR/files_$(date +%Y%m%d).tar.gz /var/www/html/xoops --exclude=cache --exclude=templates_c

# Remove old backups
find $BACKUP_DIR -type f -mtime +$RETENTION -delete

echo "Backup completed at $(date)"

Jadwalkan dengan cron:

# Edit crontab
crontab -e

# Add line (runs daily at 2 AM)
0 2 * * * /usr/local/bin/xoops-backup.sh >> /var/log/xoops_backup.log 2>&1
