SIMOS 1.0: Fundamentals of VPN Technologies and Cryptography

Network security engineers and learners preparing for Cisco CCNP Security certification

Prerequisite
None

Expected Duration
112 minutes

Description
VPNs form the basis of secure communication across a shared or public infrastructure. In this course, you’ll about the basics of VPNs and the cryptographic systems that underpin them. This course is one of a series in the SkillSoft learning path that prepares the learner for Cisco certification exam 300-209 SIMOS. This exam counts toward CCNP Security certification.
