SSL vs IPSEC Virtual Private Networks

Remote Site and Equipment magazine just published an article I submitted while I was still at Industrial Defender. The article contrasts IPSEC with SSL virtual private networks, and explores how well each meets the needs of providing access to remote sites like substations, pumping stations and compressor stations. The article also touches on a security problem endemic to "web-proxy SSL VPNs" and explains when and why to avoid that one variant of SSL VPN technology.
