Today, Virtual Private Networks (VPNs) are a cost-effective alternative to classical remote access scenarios. Moreover, they are also suited for the coupling of company sites. The utilization of the Internet makes particularly high demands on a reliable authentication and authorization of the users, as well as on data protection and security. The course will enable the participants to assess the pros and cons of L2TP, IPSec, and SSL/TLS and to perform the design and implementation of IP-based VPNs. Course Contents • Layer-2 and Layer-3 Tunnels • GRE, L2F, L2TP, and PPTP • PPP, PAP, CHAP, and RADIUS • Voluntary Tunneling and Compulsory Tunneling • Symmetrical and Asymmetrical Encryption (AES, 3DES, RSA, ...) • Data Integrity and Replay Attacks • Keyed Hash (MD5, SHA-1) • Digital Signatures and Certificates • Authentication • IPsec: Tunnel Mode and Transport Mode • Encapsulating Security Payload (ESP) and Authentication Header (AH) • VPNs with SSL and TLS • VPN Concentrators and Home Gateways • MPLS VPNs vs. IP VPNs Detailed Table of Contents In this course of the ExperTeach Networking series, each student will receive the comprehensive ExperTeach course documentation. Target Group The course addresses network administrators and designers who are responsible for the planning and technical implementation of VPNs on the basis of different tunneling technologies and who wish to acquire the responsible know-how for these tasks. Knowledge Prerequisites Profound network know-how, particularly of the TCP/IP Protocol Stack and the corresponding addressing and routing concepts, is required. Moreover, knowledge of point-to-point protocols will be helpful. IPVP |
