Abstract (2. Language): 
With the dramatic increase of the use of the Internet and its applications increase necessity of high level of security services. VoIP is one of the Internet applications and biggest problems with VoIP technology are bandwidth and security threats. The attacks with the use of vulnerability on VoIP systems can be arranged, as a result of this attack, VoIP traffic can be interrupted, can be copied, can be prevented, can be slowed or changed by an attacker. Vulnerability in a VoIP system can arise from equipment, software and protocols. This paper investigates common threats and attacks that used on VoIP technology and different precautions and security technologies. Security simulations are realized by using OPNET modeler and secure VoIP technology components required for secure communication have been identified.

Abstract (Original Language): 
Internet ve uygulamalarının hızlı bir şekilde artması yüksek seviyeli güvenlik servislerine olan ihtiyacı attırmaktadır. İnternet uygulamalarından VoIP teknolojilerinin en büyük problemi band genişliği ve güvenlik tehditleridir. Güvenlik açıkları kullanılarak, VoIP sistemlerine saldırılar düzenlenebilir. Bu saldırılar sonucunda VoIP trafiği saldırganlar tarafından kesilebilir, kopyalanabilir, engellenebilir, yavaşlatılabilir veya değiştirilebilir. Bir VoIP sistemindeki güvenlik açıkları, kullanılan cihazlardan, yazılımlardan ve protokollerden kaynaklanabilir. Bu çalışmada, VoIP mimarisine yönelik tehditler, saldırılar incelenmiş, bu tehditlere karşı geliştirilen önlemlere ve teknolojilere değinilmiştir. OPNET modelleme programı kullanılarak, güvenlik simülasyonları gerçekleştirilmiş, VoIP teknolojisinde güvenli iletişim için gereken unsurlar ortaya konmuştur.
