BruteForce همزمان از آی پی های هم رنج

[iHSG]

ممنون از همه دوستان الان دوباره همین رنج آی پی BruteForce زده که این بار رفتم تو پیامی که دایرکت ادمین داده فهمیدم ظاهراً BruteForce ها به سرویس Exim بوده:

A brute force attack has been detected in one of your service logs.

الان PL رو به بخش CC_DENY فایروال CSF اضافه کردم.
