Traps uses a default, out-of-the-box policy to provide protection against malware and exploit. It is highly recommended to use content updates regularly to enjoy policy updates from Palo Alto Networks.
To further reduce the attack surface, one can use additional advanced policies. In the attached document, you can find these recommended policies and the suggested process required to tune these policies, so as not to create false positive events or disrupt end-user experience.
This document is relevant for Traps versions 3.3.x & 3.4.x.
Of course, let us know if you have comments or questions below.
