  • 1.  Limit / show number of authentication events for user

    Posted Tue December 15, 2020 08:07 AM
    Hello,

    is there a way to limit the number of times a user can authenticate in ISAM in a specified time period. E.g. a user is only allowed to perform 5 authentications within 60 seconds. We use client certificate authentication. Alternatively is the a way to log / view users that perform massive number of authentications. What we want to achieve is, to identify / block clients that do not properly handle cookie sessions with ISAM.

    I was looking into rate limit feature, but I am not sure if this can be done.

    Regards,
    Jurgen

    Hi Jürgen

    Although the following does not address entirely (directly) your requirements, rate limiting could become part of your arsernal:

    This blog is a good start about rate limiting, that is if you are new about it.

    According to the documentation, the rate  limiting policy file is a yaml file.
    But I can't find where we are supposed to add the yaml file. We can identify the file in the reverse proxy configuration under the  [rate-llimiting] stanza, using the policy attribute.
    But where do we place the policy file?

    Rate limiting RESTAPI endpoint is "/wga/ratelimiting", but for non-programmatic access (in the LMI), you need to navigate under "Secure Web Settings->Global Settings->Rate Limiting", and from there you can consult a few OOTB provided samples or upload you own rating files. I would recommend that you develop and upload your own rate limiting file.
