Thanks Joseph for info. >>In addition, gluster uses MTLS (each endpoint validate's the other's chain-of-trust), so you get authentication as well. Does it only do authentication of mounts. I am not interested at this moment on IO path encryption only looking for authentication. >>you can set the auth.allow and auth.reject options to whitelist and blacklist clients based on their source IPs. I have used this but unfortunately I don't see ipbased / hostbased ACL as matured method, unless GlusterFS supports Kerberos completely. The reason I am looking for key or secret based secured mounts is, there will be entire subnet granted to the service & more elegant way is to allow only the client on that subnet to gluster mount would be if they use keys/secret as the client might next cycle/reboot get different IP. I can find workaround related to IP but this seems really weird that gluster only uses SSL to encrypt IO traffic but not use the same for authenticated mount. -- Deepak > On Mar 18, 2017, at 9:14 AM, Joseph Lorenzini <jaloren@xxxxxxxxx> wrote: > > > Hi Deepak, > > Here's the TLDR > > If you don't want the I/O path to be encrypted but you want to control access to a gluster volume, you can set the auth.allow and auth.reject options to whitelist and blacklist clients based on their source IPs.

This does not address access by different unix users on that mounted gluster volume -- that's a separate and much more complicated issue. I can elaborate on that more if you want. > > Here's the longer explanation on the TLS piece. > > So there are a couple different security layers here. TLS will in fact encrypt the I/O path -- that's one of its key selling points which is to ensure confidentiality of the data sent between the gluster server and gluster client. In addition, gluster uses MTLS (each endpoint validate's the other's chain-of-trust), so you get authentication as well. Additionally, if you set the auth.ssl-allow option on the gluster volume, you can specify whether authenticated TLS client is permitted to access the volume based on the common name in the client's certificate. This provides an inflexible but reasonably strong form of authorization. > > ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
