Hi,

you should be able to do it using parameter ssl/ciphersuites. It's for ABAP stack but it should work also for ICM of Java stack. More info about parameter can be here 510007. I think you can just modify profile in /usr/sap/<SID>/SYS/profile.

Cheers,

Martin

Thanks Martin,

1.Where can i check the mentioned Ciphers in the server ?

2.This is how we configure 128 bit session key strength ?

- In work directory ( ssl/ciphersuites=129:HIGH ) ??

1. Sorry, I wasn't clear. Check the OSS note 510007. SAP divides ciphers into some categories. All ciphers are listed in that OSS note.

2. That note also says how to set up that parameter.

Hi All,

For the j2ee system, You can remove it via VisualAdmin tool -> dispatcher -> services ->

SSL Provider under the Cipher Suite tab.

Kind regards,

Cathal

Thanks Cathal.

I checked the portal & i didnt find "TLS_RSA_WITH_DES_CBC_SHA" under SSL Provider to remove.

That is strange as I see it on our own system, The Suites are not in alphabetical order though. Can you see other suites ok?
