Each rule also has an action, which determines whether you monitor, trust, block, or allow matching traffic.
Note: With action "trust", Firepower does not do any more inspection on the traffic. There will be no intrusion protection and also no file-policy on this traffic.

Cross site scripting (also known as XSS) occurs when a web application gathers malicious data from a user. The data is usually gathered in the form of a hyperlink which contains malicious content within it. The user will most likely click on this link from another website, instant message, or simply just reading a web board or email message.
Usually the attacker will encode the malicious portion of the link to the site in HEX (or other encoding methods) so the request is less suspicious looking to the user when clicked on.
For example the code below is written in hex: <a
href=javascript:alert&#
x28'XSS')>Click Here</a>
is equivalent to:
<a href=javascript:alert('XSS')>Click Here</a>
Note: In the format "&#xhhhh", hhhh is the code point in hexadecimal form.
