F5 has created a specialized ASM template to simplify the configuration process of OWA 2016 with the new version of BIG-IP v13
Click here and download the latest version of XML file that contains the template: Outlook Web Access 2016 Ready Template v6.x
Goal: Quick OWA 2016 base line policy which set to Blocking from Day-One tuned to OWA 2016 environment.
Important: If the policy is not working properly, please ensure you are using the latest version. If you have any issues or questions, please send any feedback to my email: email@example.com
How is this different than the "OWA Template" in the 13.1 base product?
Thanks Walter for reaching out, we are always in ongoing process to improve security and reduce false positive of the templates. The update touch multiple areas of the policy but mainly updated attack signatures sets and change positive models to compact mode with staging state. As well URL`s was updated with common content types.
So, this would be considered a patched version of that template then? Is there a section of the F5 download site for updated (supported) ASM Templates like there is for iApps?
Also, will this new template support OWA 2013?
Yes, it a patched version that would finally will be updated into the device template repository.
The template was tested on OW16K so there is no guaranty it would work as expected in OWA13K.
will this work with 12.1.2 ?
The template was tested on v13 so unfortunately there is no backward comparability guarantee
I've implemented a policy in transparent mode with this template, but I'm facing some issues during traffic learning:
a) ActiveSync triggers strange SQL-Injection Suggestions: SQL-INJ "' --" (SQL comment) (Parameter) (2)
Is there any suggestion how to handle these suggestions in a good and secure manner?
Thanks Amir for updating about the issue with active-sync, As far as I understand you are testing in clear environment? could you please export the illegal logs and send it to my email nashkenazi@ so I will take a look (via Events Logs -> Applications -> Request -> Select All -> Export) ?
Hi Nir, thanks for the quick reply. Unfortunately I had no logging profiles bound currently. I've just changed it and I'm waiting for a few events to occur. I hope to send you the logs latest by tomorrow.
I am using the template for v13.1. I updated the attack signatures as described in step 2, and this is the first line of the readme:
Importing the policy (step 3) completes successfully, but gives me 64 lines of the following before the success message:
signature with id xxxxxxxxx (previously used in this security policy) does not exist on this system.
I searched for a few IDs via Security ›› Application Security : Attack Signatures and saw that none of them seem to have an entry. What effect, if any, does it have on the policy if the XML file refers to attack signatures that are not defined on the box?
And does that mean the XML file is outdated (and with it the policy) every time the signature file gets updated?
Thanks for the update Mr. Gundemarie, the logs are related to signatures that was removed, so it safe to ignore the logs. I would suggest to take the latest template 6.1.6 that was updated recently.
Hello, have tried the Tamplate correspond.
At the beginning, the call of OWA was also, but now I get a blocking.
"Modiefied domain cookie Cookie Name: Clientid Reason: New Cookie"
Thanks Udo for reaching out, usually the alert is raised only after upgrading/changing the policy but it should stop after existing sessions are expired.
See https://support.f5.com/csp/article/K20323120 for more information.
If you think that is still occurs and it is a false-positive, you can remove the block protection: Security ›› Application Security : Policy Building : Learning and Blocking Settings >> Cookies >> Modified ASM cookie
Modified ASM cookie is unplayed.
Now have Security >> Application Security: Headers: Cookies List ClientID set by Enforced Coolies to Allowed Cookies. Then the call goes again
Thank you Nir for your great efforts.
Can we know if this template for http or https ? or both ?
As well as supporting OWA with ActiveSYNC or donot ?
Thanks Ahmed, the policy support both "http"/"https" protocols and "ActiveSync".

Just to confirm , this template applied only to OWA or all the Exchange services ?
Thanks a lot.
Thanks for helping, I fixed the link.
The template is for front end exchange user access (OWA/Outlook) applications and the exchange servers.
Just a quick question, does this template works for versions 14?
