Brute-force attack protection rules

Brute-force attack protection rules to create, edit and view rules for incoming and outgoing network connections. The pre-defined rules cannot be edited or deleted. Create a new rule, click Add new Brute-force attack protection rule, or Edit selected entries.

To ensure the highest possible protection, the blocking rule with the lowest Max attempts value is applied even if the rule is positioned lower in the Rules list when multiple blocking rules match the detection conditions.
