v.24.2New Feature

Allow setting quota for maximum sequential login failures

Allow to set up a quota for maximum sequential login failures. #54737 (Alexey Gerasimchuck).
Introduces a quota to limit the maximum number of sequential login failures for users in ClickHouse.

Why it matters

This feature helps enhance security by preventing brute-force attacks and unauthorized access attempts through consecutive failed login tries. It allows administrators to restrict the number of sequential login failures, thereby protecting the server from potential abuse or credential guessing.

How to use it

Configure the quota for maximum sequential login failures using ClickHouse's quota management system. Define a quota with a limit on sequential login failures and assign it to users or user profiles to enforce the restriction.
