CHAPTER SUMMARY

VPN management is a complex activity that requires attention to detail and good documentation. A variety of best practices may assist you in your VPN deployment and ongoing support. Selecting and deploying a VPN solution that meets your business requirements is essential. This includes deciding between open-source and commercial VPN solutions when selecting your product. Understanding the threats, attacks, and mitigations and ensuring that your VPN is available are key components of success. In addition, you must understand the difference between privacy and anonymity; know the difference between personal/individual and enterprise/network solutions; and, finally, be able to train your users well. Once you have mastered all these facets of successful VPN rollout and support, you will be ready to move on to other security topics.
