Below is a list of some podcasts worth considering if you are interested in learning about networking, certifications and security. The links below are via Soundcloud but you can also find these podcasts hosted on Itunes, Spotify and other platforms.
The Broadcast Storm is presented by Kevin Wallace and is a networking-centric podcast which sees him discussing topics from changes in Cisco certifications, or explaining more technical aspects such as specifying three ways to filter OSPF routes and talking to industry figures. Kevin is a two-time CCIE in Routing & Switching and also in Collaboration. His experience has been achieved working for the likes of Walt Disney World Resort, Skillsoft, and Eastern Kentucky University. Kevin has also produced video content & books for Cisco Press and Pearson IT Certification. He now owns and operates Kevin Wallace Training, LLC, a provider of self-paced training materials that simplify computer networking. You can listen to his podcast here:
The Naked Security podcast is a collaboration of a number of staff at cyber security company Sophos. Almost like listening to a chat show (without the celebrities) it covers major developments in the news in relation to security matters. Its a good place to get an understanding of cyber security topics.
Lastly Cisco have their own Cisco Champion Radio which they describe as ‘A Podcast series by technologists for technologists.’ Topics again are centred around the networking industry, including enterprise networking, collaboration, data centre, Internet of Things and other Cisco software & products.
