The negative enforcement option within the Bot Detection (Web Scraping) feature might prevent normal behavior from being detected as such, even after disabling the negative enforcement using the internal parameter: ws_cshui_susp_event_bot_score. Disabling negative enforcement is done using an internal Pp/usr/share/ts/bin/add_del_internal add ws_cshui_susp_event_bot_score 0 bigstart restart asm
Some web clients may get blocked due to this anomaly.
-- Bot Detection (Web Scraping) is enabled on the ASM Security Policy. -- The client uses rarely encountered hardware that causes negative enforcement to be detected. -- Negative enforcement is disabled via ASM internal parameters.
