More SIP Protocol Security & Compliancy
Providing all important layers of SIP security.
Solid firewalls have deep packet inspection (DPI) capability, which gives Ingate the ability to look at Layer 2 through Layer 7 of the OSI model. As the SIP protocol is an application layer (Layer 7) in the OSI model, some products have a unique ability to evaluate the SIP protocol packets and provide non-protocol compliance rules, routing rules and policies. Deep packet inspection also provides an important layer of security.
How else does a proper plan ensure security for SIP applications?
Products which strictly adhere to the SIP protocol, look specifically for SIP compliancy. If there is a failure of SIP protocol compliance, the Ingate will use SIP components such as its full SIP proxy and SIP B2BUA to correct or discard SIP traffic to resolve compliancy issues.
Such products can also apply policies to correct SIP non-conformances in various applications such as:
Removal of VIA Headers SIP Method Processing Rules MIME Content Filtering SIP Offer / Answer Call Flow Escaped Whitespace Rules SIP Method Authentication URI Encoding Session Timers 180 Response Removal Username Checks Limitation of Media Streams Better Reliability UDP Packet Size Limitation of RTP Codecs and so much more! Depending on the nature of the failure to adhere to the protocol, the Ingate can also invoke a denial of service.
