Takeaway: Cross site scripting occurs when a web application gathers malicious data from a user. Besides attempting to have website code securely written, an external security research team is always beneficial to identify overseen security bugs that can scale to large exploits. Additional protection and monitoring by IDS and system logs will show such exploit attempts, so steps can be taken to quickly stop attacks.
