When launching or redesigning a website, a business leader is likely to focus on its esthetic qualities and usability. After all, a gorgeously designed website with excellent navigation tools is sure to enhance brand reputation and reduce bounce rates.
However, it’s vital that web developers also prioritize online security. Did you know, for example, that there were between 20 and 25 major ransomware attacks every day in 2024? Or that financial losses from cyber incidents have increased fourfold since 2017? Not to mention the fact that secure websites are more SEO-friendly and perform better in Google rankings.
As emergent technologies such as AI transform the digital world, cyber criminals are coming up with new ways to target businesses. It’s no wonder, therefore, that 66% of organizations expect AI to have the biggest impact on cybersecurity in the coming year compared to other vulnerabilities. So, how can web developers keep on top of growing threats and ensure websites stay safe and functional? Here are three top tips every web development professional should know in 2025.
Keep code secure
Writing secure code represents the foundation of every decent web security plan. Best practices for preventing attacks include:
- Prevent SQL injection: Cyber criminals sometimes attack websites by manipulating input fields and executing malicious SQL queries. You can prevent this by using prepared statements and parameterized queries.
- Preventing cross-site scripting (XSS): XXS occurs when hackers inject malicious scripts into websites and steal sensitive information. Developers can prevent this issue by using security frameworks and libraries that filter out untrusted data before rendering it on webpages. Just remember to regularly update the frameworks and libraries for maximum protection.
- Monitoring security events: Keep track of authentication attempts, failed logins, and other critical security events to detect any anomalies at an early stage.
- Using HTTPS: You should always use HTTPS (SSL/TLS) to encrypt data and enforce HSTS (HTTPS Strict Transport Security to prevent protocol downgrade attacks.
Protecting user data and ensuring compliance
Web developers should ensure the secure handling of user data in compliance with regulations such as GDPR. Failure to protect user data could lead to significant penalties, financial losses, and reputational damage. Key steps to protect user data include:
- Use SSL/TLS encryption for web applications that collect personal information.
- Stay abreast of privacy regulations such as the GDPR (General Data Protection Regulations) in Europe. As part of this, web developers should give users the option to manage their data and delete personal information.
- Mask sensitive user data. For example, websites should only make visible the last four digits of customer credit card numbers.
- Incorporate automatic log-outs for inactive users and enforce reauthentication features for sensitive actions.
Conclusion: Prioritize secure web development in 2025
As you can see, staying vigilant to emerging cyber threats is fundamental to business success and reputation. Web developers must adapt to emerging threats to ensure clients’ sites remain secure and competitive.
