Security policy configuration problem

Hi I use ASM for my applications. After I saw false positives from security-> event logs-> application-> requests. I removed the ticks from security-> application security-> blocking-> settings Evasion technique detected -> bad unescape and HTTP protocol compliance failed-> Header name with no header value options. But after few days I took same errors from ASM. After I checked the blocking options, I saw the bad unescape and header name with no header value options are still chosen. This problem occured 4-5 times. I'm sure that I saved the policy and applied the changings to the policy. How can I solve the problem? My F5 version is 11.6.1hf 1.0.326 Thanks for your help.

  • Did you choose the policy from the drop down list before you disable the evasion block settings? Are you still seeing it as enabled Security ›› Application Security : Blocking : Settings?

  • To reiterate Jinshu, make sure that you are editing the correct policy. If it still doesn't work, try [tmsh restart sys service asm] and see if that clears up the problem.
