1. Thiếu Cập Nhật Phần Mềm
Outdated software, including CMS (like WordPress), plugins, and themes, often contain known security vulnerabilities. Hackers actively exploit these weaknesses. Regular updates are essential to patch these security holes. Failing to update your website’s core software and plugins leaves it vulnerable to exploitation. The consequences can range from minor inconvenience to a complete website takeover, resulting in significant financial and reputational damage.

Weak passwords are a major security weakness. Easily guessed passwords leave your website vulnerable to brute-force attacks. Choosing strong, unique passwords—a mix of uppercase and lowercase letters, numbers, and symbols—is crucial. Consider using a password manager to generate and store complex passwords securely.
3. Thiếu Bảo Vệ SQL Injection
SQL injection attacks exploit vulnerabilities in poorly written database queries. This can allow attackers to manipulate your database, potentially stealing sensitive user information or even controlling the entire website. Implementing parameterized queries and input sanitization are crucial steps to prevent SQL injection. Phát hiện lỗ hổng website related to SQL injection requires thorough testing and code review.
4. Không Sử Dụng SSL/TLS
A lack of SSL/TLS encryption leaves your website vulnerable to man-in-the-middle attacks, where attackers intercept sensitive data transmitted between your website and users. SSL/TLS encrypts this data, protecting it from prying eyes. This is vital for e-commerce sites and any website handling sensitive user information. Implementing SSL/TLS creates a secure connection, denoted by the padlock icon in the browser’s address bar. The importance of SSL certificates can’t be overstated.
5. Thiếu Firewall Website
A firewall acts as a barrier between your website and malicious traffic. It filters incoming and outgoing network traffic, blocking potentially harmful connections. Without a firewall, your website is more exposed to various attacks. A web application firewall (WAF) offers an additional layer of protection, specifically designed to thwart web-based attacks. Consider a cloud-based firewall for added scalability and ease of management. Regularly review firewall logs for suspicious activity.
