For my asp.net mvc 3 project, I'm considering the best approach for handling data: should I pass all the data via JSON and filter it with JavaScript, or should I filter the data first and then convert it to JSON?
If filtering the data before passing it as JSON is the preferred method, how should I proceed with this process?
If you want to enhance the security of your data, I recommend implementing filters on both the client and server sides.
You can utilize jQuery validation, such as the jquery.validate() plugin, and follow best practices found on this website:
On the server side, it is crucial to verify and sanitize all incoming and outgoing data, especially if displaying user-input data.
While MVC has built-in security measures like detecting malicious data and using anti-forgery tokens, exercising control over your data is always recommended. ;)
The approach you take really hinges on the specific objectives you are aiming to achieve. I can discern two distinct scenarios that may apply.
To sum up: restrict the quantity of data being transferred, ensure no sensitive information is shared unnecessarily (even if not displayed), and maximize client-side processing capabilities to optimize user satisfaction.
