How to Check If Your JavaScript Security Is Working

How do I know if my JavaScript security is working?

The best way to improve JavaScript security is through the use of scanning tools that detect, identify, and alert on behavior anomalies, and with automated JavaScript-specific security policies that can automatically apply security configurations and permissions to help continuously monitor and protect malicious client-side activities.

Other things organizations can do to improve their overall JavaScript security include:

Use secure software development practices: Apply best practices that enable the development of more secure application code and well as aid in the detection and elimination of errors early in the application development process.

Use automated monitoring and inspection: Monitoring and inspection activities are critical, but also time consuming if you don’t have an automated solution to regularly review JavaScript code. A purpose-built solution that automates the process can be a fast and easy way to identify unauthorized script activity.

Move security to the ‘left’: Security can’t just happen after a web application is built or installed on a system. It needs to be a part of the entire website and application development process—from beginning to end.

Audit your web assets: Know what web assets you own and the type of data they hold and regularly conduct automated deep-dive scans to reveal intrusions, behavioral anomalies, and unknown threats.

Maintain safe JavaScript libraries: Confirm the security of any external libraries by making sure they’re not on any blacklists. Regularly patch and update your libraries and avoid any dependence on third-party library sources.

Be selective with third-party scripts: Third-party JavaScript is a great way to avoid the time and money associated with developing your own code, but third-party scripts can also contain vulnerabilities or intentional malicious content.

Validate input: XSS risk can be minimized by validating input before invoking JavaScript functions.

Next steps to make sure your JavaScript security is working

JavaScript carries risk for organizations by increasing the number of vulnerabilities that exist on the client side. Protect your customers and your websites by using the right types of JavaScript security. If you would like to ensure your JavaScript is safe, check out our Inspector and PageGuard products. They are specifically designed to continuously monitor, inspect, and scan websites that run JavaScript to protect them from attack.
