    Hello Massimo,

    Which FlashSystem do you have and which Virtualize versions are installed on it?

    This is usually controlled using the chsecurity command or under Settings -> Security -> Security Protocol Levels. Here you can configure the required SSL level, whereby the default level corresponds to compatibility mode.

    The newer the Virtualize version, the more options are available for the requirements.

    https://www.ibm.com/docs/en/flashsystem-7x00/8.7.0?topic=commands-chsecurity

    I hope this helps.

    Hello Patrik,

    my firmware version is 8.5.0.5 but in Settings -> Security I don't have Security Protocol Levels but Secure Communications 

    I read the chsecurity command guide but I don't understand how to disable only http access to the web gui.

    Thanks in advance for help.

    If it helps the GUI doesn't actually use HTTP connections, all traffic is actually handled using https.  You'll notice this in your browser that even when you use http, you will be forwarded to an https address.

    Please note that the system will default to a certificate you will need to trust or you will need to install a trusted signed certificate on the cluster in order to get most browsers to be happy with the GUI.

    You can find out more from our Security white paper here: https://www.redbooks.ibm.com/redpapers/pdfs/redp5716.pdf 

    The Proxy support is an http (which tunnels a TLS connection), but other than that everything else is https.

    Hello Massimo

    You can use this command, the full chapter is in the following redbook

    IBM Storage Virtualize, IBM Storage FlashSystem, and IBM SAN Volume Controller Security Feature Checklist - For IBM Storage Virtualize 8.6

    https://www.redbooks.ibm.com/redpapers/pdfs/redp5716.pdf

    Login interfaces
    The system provides a CLI, GUI, and a REST application programming interface (API), all of
    which authenticate users and allow them to administer the system. All interfaces implement
    data in-flight encryption to secure the login and all subsequent interactions with the system.
    Command line interface
    Users log in to the CLI by using an SSH client terminal window. Logging in to the system by
    using a terminal places the user in a highly restricted shell. For example, the user cannot run
    a change directory command and can run only the commands that are designated by IBM as
    required to administer the system.
    Consider the following points:
     This login interface can be disabled on a per-user group basis.
     This login interface cannot be disabled for the superuser.
    For more information. see the following IBM Documentation web pages:
     UNIX commands available in interactive SSH sessions
     Command-line interface
     Changing user groups
    Graphical user interface
    Users log in to the GUI is by using a Hypertext Transfer Protocol Secure (HTTPS) connection
    from Transport Layer Security by using a supported web browser.
    You can install certificates signed by a certificate authority (CA) with the suitable certificate
    chain. The system supports the following system certificate key types:
     RSA 2048-bit
     ECDSA 384-bit
     ECDSA 521-bit
    The system presents the installed system certificate and chain to web browsers when they
    connect to the system.
    This login interface can be disabled on a per user group basis.
    By default, the superuser is exempt from disabling this interface. To disable this interface for
    the superuser, run the chsecurity -disablesuperusergui yes command.

    I hope this is helpful.
     
    Best regards.

    Howdy,
    Already in this port list for Virtualize 8.5 (the oldest supported release as of today, GA 03/2022), port 80 is listed as being forwarded to https transport: Security levels and supported security ciphers - IBM Documentation

    Out of four available security levels to choose from, even the weakest did not support TLS1.1 or lower.

    Regard,

    Ilja

    Hi all,

    as I can understand there is a proxy server that redirect http call on port 80 to https address.

    So next question is if there is the possibility to disable this proxy service.

    Thanks

    Hi,

    In the following table not even mentioned the HTTP 80 port.
    https://www.ibm.com/docs/en/flashsystem-7x00/8.5.0?topic=pip-ip-address-allocation-usage

    I assume that this redirection is not a configurable option for the administrator.

    Regards,

    It's not a proxy server, it is an internal rules definition.  This is not configurable, given that we are always using https this is generally enough for security auditors.

    Hope that helps.
