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: to steal or modify sensitive information.
XSS (Cross-Site Scripting) attacks
Injection of malicious scripts to hijack user sessions.
Can be used to steal cookies or infect visitors with malware.
Ransomware and malware
Infecting a web application with 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 in order 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. Using 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 plugins regularly
Updates correct security vulnerabilities exploited by hackers.
Remove unnecessary extensions to reduce risk.
4. Securing 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 those users strictly necessary.
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
Create penetration tests (pentests) to identify and correct faults.
Use tools such as OWASP ZAP, Burp Suite or Nessus.
8. Set up a backup and recovery plan
Visit 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
