The IT strategies and measures taken to protect SIP (Session Initiation Protocol) applications from vulnerabilities and potential threats when deployed within a business network. Employing SIP protection measures can help a network maintain resiliency by driving efficient performance for valid users and working to prevent malicious traffic from gaining access.

Businesses implementing SIP security within their system will have the advantage of deploying SIP applications into their network while being protected from a variety of potential threats such as Denial of Service (DoS) attacks, worms, Distributed Denial of Service (DDoS) attacks and other harmful activities. Floods of SIP messages and UDP packets can also easily consume server resources, dominate bandwidth usage, and degrade voice and video service quality. If any of these activities are left unchecked, SIP server crashes may result, hindering or even completely paralyzing a business's SIP functionality. Providing adequate fail-over measures is crucial to maintaining functional SIP abilities within a business network. With the appropriate SIP security strategy in place, companies will be able to provide available network access to users while guarding business-sensitive information from harmful traffic. Along with protecting a system, security advantages extend to future growth within a network. As SIP traffic increases, security allows for scalability in a network.
