What it detects

This rule flags Huawei BGP log events containing the ':179' protocol marker and the message 'BGP_AUTH_FAILED'. Repeated authentication failures can indicate an attacker attempting to disrupt or gain access to BGP sessions to influence network routing. Detection relies on Huawei BGP log telemetry with specific authentication-failure text.
