Analyzing Compatibility and Ensuring Security

I recently started using Parse and have been exploring the documentation and answered questions. However, I still have a couple of inquiries on my mind.

Firstly, I discovered that the Javascript SDK does not function on IE9 and IE8 without an SSL certificate. Can Rest API be utilized to work with these browsers even without an SSL certificate?

My second question pertains to the security of Javascript and API/SDK keys. While I've seen suggestions like checking for valid sessions and limiting certain actions for users, how can I prevent users from manipulating their own scores (obtaining my key, obtaining a session token, then modifying the score class to add a million points)? How can I safeguard my app against such potential threats?

Thank you in advance for your time and responses.

Answer №1

If you're concerned about security when using Javascript and API/SDK keys, it's important to acknowledge the limitations. While there are measures you can take to protect your app or website, ultimately, a determined user may still find a way to bypass them.

One strategy to enhance security is utilizing Cloud Code. By implementing a Cloud Function that validates data before saving it, such as checking if a provided score is within reasonable parameters based on other variables like enemies killed, you can add an extra layer of protection:

// Confidential logic stored in your Cloud Function
var maxScorePerEnemy = 750;

if (score > (enemiesKilled * maxScorePerEnemy)) {
    // Identifying and handling cheating behavior
}

For more robust defense, consider generating temporary tokens that must accompany scores submitted. While this method may not prevent all illicit activities, it raises the difficulty level for potential cheaters.
