Packet Analyzers Network Tools

Günümüz iletişim dünyasının temeli olan TCP/IP’nin önemi gün geçtikce artmaktadır. TCP/IP ağlarda dolaşan tüm veriler birer pakettir ve bu paketlerin yapısı ne kadar iyi bilinirse TCP/IP ve güvenliği konusunda çıkabilecek sorunlar o kadar kolay anlaşılır ve çözüme kavuşturulur. Sınır güvenliği (Router, Firewall, IDS, IPS, NDLP vs) bileşenlerinin temeline inildiğinde karşımıza çıkacak en önemli iki bileşen paket ve protokol olacaktır. Paket, protokol kavramlarının detaylı olarak anlaşılmasının en kolay yolu “Sniffer” olarak da adlandırılan ağ paket/protokol analiz programlarıyla pratik çalışmalar yapmaktır. Aşağıda BT ağ ve güvenlik yöneticilerinin en sık kullandıkları paket/protokol analiz programlarını bulabilirsiniz.
