.SYNOPSIS
|
||
Мониторинг логинов/попыток входа с уведомлениями в Telegram
|
||
.DESCRIPTION
|
||
Отслеживает события входа в систему (Security 4624/4625) и события RD Gateway (302/303),
|
||
отправляет уведомления в Telegram, делает ротацию логов, heartbeat в файл и ежедневный отчет.
|
||
.NOTES
|
||
Требуется: PowerShell 5.0+, запуск от администратора.
|
||
Важное:
|
||
- На некоторых серверах RDP-логин приходит как LogonType=3, поэтому интерактивные типы: 2/3/10.
|
||
- Добавлены исключения шума: DWM-*, UMFD-*, HealthMailbox*, Font Driver Host*, NtLmSsp и др.
|
||
- Heartbeat без дрейфа: используется nextHeartbeatTime (а не "прошло N секунд").
