Cyber-attacks on web applications are on the rise, endangering company and user data. With the rapid evolution of techniques used by hackers, it is crucial to strengthen web application security to prevent intrusions, data theft and service interruptions.
In this article, we will look at what are the new cyber threats? and how to secure your web applications effectively.
1. New cyberthreats targeting web applications
As technology advances, cybercriminals are developing ever more sophisticated attacks. Here are some of the major threats in 2025:
🔹 SQL injection attacks
✔ Hackers insert malicious code into a form or URL to access databases.
✔ Objective: steal or modify sensitive information.
🔹 XSS attacks (Cross-Site Scripting)
✔ Injection of malicious scripts for hijack user sessions.
✔ Can be used to steal cookies or infect visitors with malware.
🔹 Ransomware and malware
✔ Infection of a web application via security holes in plugins or extensions.
✔ Objective: encrypt data and demand ransom to recover them.
🔹 DDoS (Distributed Denial of Service) attacks
✔ Hackers overload a server with massive traffic to make the site unavailable.
✔ Impact: loss of sales and damage to reputation.
🔹 Session hijacking
✔ Hackers steal users' session credentials to gain unauthorized access to their accounts.
These threats require advanced security strategies to effectively protect your web application.
2. Best practices for securing your web applications
Here are the essential measures to strengthen the security of your web application in 2025 :
🔑 1. Use an application firewall (WAF - Web Application Firewall).
✔ Filters out malicious requests and blocks XSS, SQLi and DDoS attacks.
✔ Examples: Cloudflare, AWS WAF, Imperva.
🔒 2. Encrypting data with SSL/TLS
✔ Activate a SSL certificate to encrypt communications between the browser and the server.
✔ Check that your site uses HTTPS instead of HTTP.
🛠️ 3. Update your software and plug-ins regularly
✔ Updates correct security vulnerabilities exploited by hackers.
✔ Remove unnecessary extensions to reduce risk.
👤 4. Secure user IDs and accesses
✔ Activate multi-factor authentication (MFA) to protect administrator accounts.
✔ Set up a strict management of roles and permissions.
🚧 5. Protect your database against SQL injections
✔ Use parameterized queries to prevent SQL injections.
✔ Limit your database privileges to strictly necessary users.
🛑 6. Protect against DDoS attacks
✔ Configure anti-DDoS services like Cloudflare or Akamai.
✔ Set up real-time monitoring to detect any suspicious activity.
📊 7. Perform regular safety tests
✔ Realize penetration tests (pentests) to identify and correct faults.
✔ Use tools like OWASP ZAP, Burp Suite or Nessus.
📌 8. Set up a backup and recovery plan
✔ Perform automatic backups and store them on a secure external server.
✔ Regularly test the restore backups to avoid data loss.
3. Recommended tools for securing your web applications
🔹 Cloudflare
✔ Advanced WAF protection against XSS, SQLi and DDoS attacks.
🔹 Bitdefender GravityZone
✔ Secures your servers and applications against malware and ransomware.
🔹 OWASP ZAP
✔ Scans and detects vulnerabilities on your website.
🔹 Let's Encrypt SSL
✔ Provides a free SSL/TLS certificate to secure your connections.
🔹 Google reCAPTCHA
✔ Prevents bot attacks and protects forms from spam.
4. Why outsource your web application security?
Entrust the security of your application to cybersecurity experts can save you time and guarantee optimum protection.
✔ Continuous monitoring and automatic updates
✔ Reduce the cost of cyber attacks
✔ Compliance with international security standards (ISO 27001, GDPR, Swiss LPD)
