A first invite message is received at a Session Border Controller (SBC) to establish a communication session. For example a Session Initiation Protocol (SIP) INVITE is received. The first invite message comprises a first hash of a fingerprint. For example, the hash may be a hashed session key. A media message is received that contains the fingerprint to establish a media stream for the communication session. A second hash is created using the fingerprint in the media message. The first hash is compared to the second hash. In response to the first hash matching the second hash, a Network Address Translator (NAT) latches to an address and/or a port in the media message. Thus, the correct media stream is associated with the communication session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for prevention of denial of service attacks for hosted network address translator","description":"To determine the correct media stream to latch onto, the system and method uses a hashing algorithm to uniquely identify a legitimate media stream.
