What Is Website Cybersecurity?

Website Cybersecurity refers to the practice of protecting websites, servers, and web applications from unauthorized access, attacks, or data breaches.
It involves securing your code, managing user access, encrypting sensitive data, and keeping your systems up to date.

In short, it’s about making sure your site and users are safe from hackers and data theft.

⚠️ Common Website Security Threats

Here are some common threats that every website owner should be aware of:

SQL Injection (SQLi) – Attackers inject malicious SQL commands to access or destroy your database.

Cross-Site Scripting (XSS) – Attackers inject scripts into your pages to steal cookies or user data.

Cross-Site Request Forgery (CSRF) – Tricks users into performing actions they didn’t intend.

Brute Force Attacks – Automated bots try multiple passwords to gain access.

Malware Infections – Insertion of harmful code to spread viruses or steal data.

Phishing & Social Engineering – Tricking users into revealing login credentials.

🧰 Basic Security Practices for Websites
1. Use HTTPS

Always use SSL/TLS encryption to secure communication between the server and users.
Example:

sudo certbot --apache -d yourdomain.com


This command installs a free SSL certificate from Let’s Encrypt
.

2. Sanitize User Inputs (Prevent SQL Injection)

In PHP, never trust user input. Always use prepared statements:

<?php
$stmt = $conn->prepare("SELECT * FROM users WHERE email = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$result = $stmt->get_result();
?>


This prevents attackers from injecting harmful SQL code.

3. Use Password Hashing

Never store plain text passwords. Use PHP’s password_hash() and password_verify() functions:

<?php
$hashed = password_hash($password, PASSWORD_BCRYPT);
if (password_verify($password, $hashed)) {
echo "Password verified!";
}
?>

4. Keep Software Updated

Regularly update your:

PHP version

Database software

CMS (like WordPress, Joomla, etc.)

Plugins and libraries

Outdated software is the easiest way hackers gain entry.

5. Restrict File Uploads

Always validate and sanitize uploaded files. Example:

<?php
$allowed = ['jpg','png','pdf'];
$ext = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);

if(!in_array($ext, $allowed)){
die("Invalid file type!");
}
?>


Never allow direct access to uploaded files — always store them in a protected folder.

6. Use Firewalls and Security Tools

Web Application Firewall (WAF) filters harmful traffic.

Tools like Cloudflare, Sucuri, or ModSecurity can protect your site from DDoS and XSS attacks.

7. Backup Regularly

Automate your backups. You can use:

mysqldump -u root -p dbname > backup.sql


Store backups securely (offline or in cloud storage).

🧠 Pro Tip: Monitor and Log Everything

Logs help you detect unusual activities early.
In PHP, you can create a simple log file:

<?php
error_log("User ".$_SERVER['REMOTE_ADDR']." accessed ".$_SERVER['REQUEST_URI']."\n", 3, "access.log");
?>
