NETWORKING PODCASTS
IPv6 will solve the problem of the IP addressing space issues we're experiencing with IPv4, but may leave you open to security threats if you don't know how it works. Understand IPv6 vulnerabilities, and alleviate your concerns by arming yourself with the tools and methods talked about in this podcast interview with IPv6 Security: Protection measures for the next Internet Protocol author Scott Hogg.
Read a Q&A on IPv6 network security threats from both book authors Scott Hogg and Eric Vyncke. Read Introduction to IPv6, Chapter 1 of the book IPv6 Security to learn more. Learn about the network security issues associated with the Internet Protocol version 6 (IPv6) from 'IPv6 Security' book author Scott Hogg. In this podcast interview he explains how you can protect your enterprise network against these vulnerabilities and more.SearchNetworking.com's certification article two weeks ago about the importance of getting certified despite rising costs got a number of reader responses. One of the most common refrains was that -- as one reader put it -- employers in the past didn't seem to care about certifications, but now the credentials appear indispensable even as companies seem less willing to defray the costs. That reader, from Riverside, Calif., said he will move forward and study for the CCNA exam without knowing whether he can really afford all the costs.
Today, we have Fred Weiller, director of marketing for Learning@Cisco, to answer some of your questions in a podcast. He addresses topics ranging from why today's economy is better suited for those with certifications, to what Cisco is doing to keep the challenging certification process as affordable as possible, including new online initiatives to aid both self-training and to point potential students to government-sponsored or -subsidized education programs. After readers wrote in to ask how they could get certified for less, we got Learning@Cisco's Fred Weiller on the phone to explain why certifications are more important than ever, and how you can afford them.
