Sean Walberg is currently a network engineer for a large Canadian financial services company. His responsibilities include maintaining two large Internet hosting centers that make extensive use of Check Point products.
Over his career thus far, Sean has focused on networks and Internet security, with a brief diversion as a Unix developer. The love of Unix, especially Linux, has stuck with him since, and he has found numerous uses for it in his network and security roles.
Although this is Sean's first book-length project, he served a two-year stint as the author of a weekly Linux newsletter for Cramsession.com, a popular IT certification portal.
When not digging into routers and firewalls, Sean enjoys cooking and tinkering with electronics. He's also been known to lock himself in a room while trying to break World War IIera ciphers.
Sean is a graduate of computer engineering, where his undergraduate thesis focused on the Secure Sockets Layer, which today secures eCommerce transactions all over the Internet. He is also a registered Professional Engineer with the province of Manitoba.
He lives in Winnipeg, Canada, with his wife, two sons, and two cats.
