SP security knowledge build up

[Ramy Hashish <ramy.ihashish () gmail com>]

Hello All,

I am planning to build up a security team of fresh engineers whom are
"network oriented", any advice on the knowledge resources we can start
with? We are looking forward to building a concrete foundation of a
well-rounded security engineer, we are looking for vendor/operator agnostic
resources.

Thanks,

Ramy
