SPNGN1 1.0: The TCP/IP Transport Layer and Internet Security Threats

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.


Expected Duration
72 minutes

Many of the functions of the TCP/IP suite are governed by the transport layer protocols TCP and UDP. This course provides an overview of how these protocols provide options such as reliability and connection oriented service. Additionally, service providers using TCP/IP are exposed to a wide spectrum of security threats. This course also covers the security concerns of the service provider. This knowledge provides the network engineer with a better understanding of the foundational elements of application layer protocols and how to secure their network. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.
