Best 7 Ways to Prevent Session Fixation Attack in TypeScript-Based ERP

Understanding Session Fixation Attack in TypeScript-Based ERP Systems

Session fixation is a prevalent web security vulnerability where an attacker tricks a user into authenticating with a predetermined session ID. Once authenticated, the attacker can hijack the user’s session and access sensitive data. This threat is particularly critical in TypeScript-based ERP systems, as they handle large-scale sensitive organizational data.

This guide will explore how to mitigate session fixation attacks in TypeScript-based ERP systems, with clear examples and actionable steps.

What Is a Session Fixation Attack?

In a session fixation attack, the attacker provides a valid session ID to a user before they log in. After the user authenticates, the attacker uses the same session ID to gain unauthorized access.
Common causes of session fixation include:

1. Poor session management mechanisms.
2. Using predictable or static session IDs.
3. Not regenerating session IDs after user authentication.

Key Indicators of Session Fixation in ERP Systems

• Unauthorized user activity in accounts.
• Multiple users share the same session ID.
• Unusual patterns of session expiration or regeneration.

Best 7 Ways to Prevent Session Fixation in TypeScript-Based ERP Systems

1. Regenerate Session IDs After Authentication

Ensure session IDs are regenerated immediately after successful user authentication. Use libraries like express-session for Node.js to manage sessions securely.

Example:

import express from 'express';
import session from 'express-session';

const app = express();

app.use(session({
    secret: 'secureSecret',
    resave: false,
    saveUninitialized: true,
    cookie: { secure: true }
}));

app.post('/login', (req, res) => {
    // Validate user credentials
    if (authenticateUser(req.body)) {
        req.session.regenerate((err) => {
            if (err) {
                res.status(500).send('Session regeneration failed');
            } else {
                req.session.user = req.body.username;
                res.status(200).send('Session secured');
            }
        });
    } else {
        res.status(401).send('Invalid credentials');
    }
});

2. Set Secure and HttpOnly Session Cookies

Prevent attackers from accessing session cookies using secure flags like Secure and HttpOnly.

Example:

app.use(session({
    secret: 'secureSecret',
    cookie: {
        httpOnly: true,
        secure: process.env.NODE_ENV === 'production',
        maxAge: 60000 // Set expiration
    }
}));

Other Techniques

4. Implement Cross-Origin Resource Sharing (CORS) Policies

Restrict session ID exposure by setting strict CORS headers.

5. Enforce Session Expiration

Expire sessions after a specific idle time or a maximum duration.

6. Use CSRF Protection

Combine session fixation protection with CSRF tokens.

7. Implement Logging and Monitoring

Log all session-related events for auditing purposes.
