Katika ulimwengu wa leo wa mtandao, tovuti ni kama duka lako mtandaoni — lakini kama duka lolote, linahitaji ulinzi wa kutosha. Website hardening ni hatua ya juu ya kuimarisha usalama wa tovuti yako kwa kuziba mianya ambayo wavamizi (hackers) wanaweza kutumia.
💡 Website Hardening Ni Nini?
Ni mchakato wa:
Kupunguza mianya ya kiusalama (attack surface).
Kuzuia uingizaji wa code hatarishi (malicious code).
Kulinda data za watumiaji na configuration zako.
Kwa kifupi, website hardening hufanya tovuti yako kuwa “ngumu kuvamiwa” na salama zaidi kwa wateja wako.
🔐 1. Tumia HTTPS Kwenye Sehemu Zote
Tumia SSL Certificate ili kulinda mawasiliano kati ya tovuti na watumiaji.
Unaweza kupata bure kupitia Let’s Encrypt.
Mfano wa configuration kwenye Apache:
<VirtualHost *:443>
ServerName www.faulink.com
SSLEngine on
SSLCertificateFile /etc/ssl/certs/faulink.crt
SSLCertificateKeyFile /etc/ssl/private/faulink.key
</VirtualHost>

🧱 2. Weka .htaccess Hardening
Faili hili linaweza kuzuia directory listing, PHP execution, na unauthorized access.
Mfano wa .htaccess:
# Disable directory browsing
Options -Indexes
# Protect config files
<FilesMatch "^(config\.php|wp-config\.php|\.env)$">
Order allow,deny
Deny from all
</FilesMatch>
# Prevent PHP execution in uploads
<Directory "/var/www/html/uploads">
php_admin_flag engine off
</Directory>
🔍 3. Ondoa Version Info za CMS
Wavamizi hutumia version za CMS kujua mianya.
Kwa WordPress:
remove_action('wp_head', 'wp_generator');
Kwa PHP:
expose_php = Off
👉 Hii inaondoa version ya PHP isionekane kwenye headers.
🧰 4. Tumia File Integrity Checker
Tengeneza script inayoangalia kama faili zimebadilishwa bila ruhusa.
Mfano wa PHP Script:
<?php
$files = ['index.php', 'config.php'];
foreach ($files as $file) {
$hash = md5_file($file);
echo "$file => $hash\n";
}
?>
👉 Hifadhi hash hizi na zilinganishe mara kwa mara kuona kama kuna mabadiliko yasiyoelezeka.
🧠 5. Zuia Access ya File System
Tumia permissions bora kulingana na roles:
644 kwa mafaili
755 kwa folders
400 kwa config.php
Mfano:
chmod 400 config.php
chown www-data:www-data config.php
🔄 6. Tumia Web Application Firewall (WAF)
Tools kama Cloudflare, Sucuri, au ModSecurity hulinda tovuti yako dhidi ya:
SQL Injection
Cross-Site Scripting (XSS)
Brute Force attacks
Mfano wa ModSecurity activation (Apache):
sudo a2enmod security2
sudo systemctl restart apache2
🧩 7. Disable Dangerous PHP Functions
Hakikisha kwenye php.ini unazuia functions hatarishi:
disable_functions = exec,passthru,shell_exec,system,proc_open,popen
🕵️ 8. Tumia Monitoring & Alerting Tools
Fail2ban — kuzima IP zinazojaribu logins nyingi.
Logwatch — kufuatilia logs za server.
UptimeRobot — kufuatilia uptime wa tovuti.
🚧 9. Backup Kila Mara
Backup files + database mara kwa mara.
Mfano wa cron job kwa backup kila siku saa 12 jioni:
0 18 * * * /usr/bin/mysqldump -u root -pYourPassword dbname > /backup/db_$(date +\%F).sql
✅ 10. Fanya Security Audit Mara kwa Mara
Kila mwezi, pitia:
File permissions
PHP version updates
Plugins/themes za WordPress
Unaweza kutumia scanners kama:
Wordfence
VirusTotal
AI-Bolit
