F5 ASM To Protect APM Web Portal

Hello,

 

I have an apm (web portal) for clients (ssl vpn). i would like to protect the portal using asm but i cant find a way to establish that.

 

i know that if the virtual server has an access policy attached to it and an asm security policy, than the apm takes the connection first and the asm has no meaning.

 

i tried to create a virtual server with asm that will forward the HTTPS traffic to an internal virtual server using an irule but the internal virtual server cannot be assigned without an http profile - a must for access policy.

 

any suggestions regarding this issue will be appriciated!

 

thanks

    Hi Or,

     

    I read alot about HTTP profile enable virtuals in front of APM enabled virtuals in a vip-targeting-vip configuration, but afaik is this configuration somewhat complex and also seems to have certain limitatations.

     

    Beside of the possibility to pull of that specific configuration trick, what is in your opinion the effective outcome of that approach? Is the ASM module more secure than the APM module? Why not use APM to filter out any anonymous request, before letting ASM parse the remaining attacks?

     

    Cheers, Kai

    Hey Kai,

     

    ASM or any other WAF in from of the APM has it's added value since it has it's own signature mechanism and the ability to mitigate attacks which are not always included in the f5 apm module, such as Brute Force, CSRF and many others.

     

    in my opinion it's adds another layer of security and visibility.

     

    as to it's complex configuration, still haven't found a way to create such and i'm hoping one of the members here will have an idea of solving this.

     

    Thanks Or.

      Hi Or, Thanks for your insights. ;-) Your mileage may vary, especially when it comes to protection for yet unknown threats and the level of visibility. Personally I do believe that most of the ASM security features are not needed for APM and also I'm also not aware that APM module is subject to OWASP top 10 issues. But well, its all about believes, isnt it? So good luck finding a solution to get your desired configuration! Cheers, Kai

      availability? The way sessions are created on the APM and the MaxAccessSession which is not that high on low-middle end platforms... maybe

      I have the same problem, I need end-to-end application attack visibility even in front of the APM module. As it stands we won't be able to tell what types of attacks are happening on the APM hosted pages and this is not acceptable. What are the issues with creating an ASM virtual server in front of the APM module or adding this as a feature? In my professional opinion it should be in front and not behind.
