Sunucu Log Kayıtlarım - Açıklarım var... :'(

Merhabalar;
Nünlük olarak hergün bu tip kayıtlar maille bana geliyor ama ne yapmam gerekiyor ne manaya geliyor tam bilmiyorum. Atraştırıp öğreneceğim ama şu açamada ilk yapmam gereken nedir? Diğerlerini zamanla öğrenirim...

Sunucuya bağlı vbulletin tabanlı büyük bir forum sitesi 3-4 tane de küçük kişisel siteler var...
Sanırım açıklarım falan var... İlk hangi açığı nasıl kapatmalıyım?

Plesk panel kurulu... Linux Centos 5 yüklü...

Ciddi manada şu aşamada ne yapmalıyım:
