Project Overview
in their application environment. These issues exposed them to risks including
information disclosure, clickjacking, cross-site scripting, and server exploitation
through open ports. The goal was to implement a comprehensive security hardening strategy
while ensuring no disruption to existing application functionality.
Key Challenges Identified
1. Improper Error Handling
The application exposed raw error messages such as server status codes
and database errors, potentially leaking system internals.
Solution: CnEL India designed and implemented a centralized error-handling
mechanism that shows only user-friendly messages to end-users while logging
detailed technical errors securely in the backend.
2. Clickjacking Vulnerability
The website was susceptible to malicious iframes, allowing attackers to
trick users into unintended clicks.
Solution: Security headers such as
X-Frame-Options: DENY and
Content-Security-Policy: frame-ancestors 'none'
were added to server responses, effectively blocking iframe embedding.
3. Missing Security Headers
The absence of critical HTTP security headers left the site open to XSS,
MIME-type sniffing, and other common attacks.
Solution: CnEL India configured robust headers including
Content-Security-Policy, Strict-Transport-Security,
X-Content-Type-Options: nosniff, and X-XSS-Protection,
ensuring industry-standard protection.
4. Unwanted Open Ports
Several unused server ports were left open, presenting unnecessary attack surfaces.
Solution: The team applied strict firewall rules, closing all
non-essential ports and leaving only secure channels (HTTP/HTTPS) active.
