Di SQL Server 2008 R2, saya mendapat beberapa laporan kebuntuan yang memiliki "* kata sandi ------------" di buffer input. Itu terlihat seperti serangan tetapi dalam kasus itu saya tidak tahu alasan atau jenis serangannya.
(log dihasilkan oleh DBA ahli bagaimana memiliki banyak pengalaman dan mengatakan kepada saya bahwa, bukan saya)
Adakah yang tahu apa itu? Terima kasih!
