Virtual Private Network (VPN) Question: Download VPN PDF

With firewalls, we went from a very small number of security-wise companies using real firewalls to firewalls becoming a "must have" on a checklist. But somehow, having a firewall became synonymous with "all my Internet security problems are solved!" VPNs and IPSEC have started off that way too. There has been a lot of "When we have IPSEC on the desk top we won't need firewalls." This is nonsense. VPNs cannot enforce security policies, they cannot detect misuse or mistakes, and they cannot regulate access. VPNs can do what they were meant to do: keep communications private.
