Project Overview<\/strong><\/p>\n

\n
The client approached CnEL India<\/strong> with critical security vulnerabilities
\nin their application environment. These issues exposed them to risks including
\ninformation disclosure, clickjacking, cross-site scripting, and server exploitation
\nthrough open ports. The goal was to implement a comprehensive security hardening strategy<\/em>
\nwhile ensuring no disruption to existing application functionality.<\/p>\n<\/section>\n
\n

Key Challenges Identified<\/h2>\n

1. Improper Error Handling<\/h3>\n

The application exposed raw error messages such as server status codes
\nand database errors, potentially leaking system internals.<\/p>\n

Solution:<\/strong> CnEL India designed and implemented a centralized error-handling
\nmechanism that shows only user-friendly messages to end-users while logging
\ndetailed technical errors securely in the backend.<\/p>\n

2. Clickjacking Vulnerability<\/h3>\n

The website was susceptible to malicious iframes, allowing attackers to
\ntrick users into unintended clicks.<\/p>\n

Solution:<\/strong> Security headers such as
\nX-Frame-Options: DENY<\/code> and
\nContent-Security-Policy: frame-ancestors 'none'<\/code>
\nwere added to server responses, effectively blocking iframe embedding.<\/p>\n

3. Missing Security Headers<\/h3>\n

The absence of critical HTTP security headers left the site open to XSS,
\nMIME-type sniffing, and other common attacks.<\/p>\n

Solution:<\/strong> CnEL India configured robust headers including
\nContent-Security-Policy<\/code>, Strict-Transport-Security<\/code>,
\nX-Content-Type-Options: nosniff<\/code>, and X-XSS-Protection<\/code>,
\nensuring industry-standard protection.<\/p>\n

4. Unwanted Open Ports<\/h3>\n

Several unused server ports were left open, presenting unnecessary attack surfaces.<\/p>\n

Solution:<\/strong> The team applied strict firewall rules, closing all
\nnon-essential ports and leaving only secure channels (HTTP\/HTTPS) active.<\/p>\n<\/section>\n
