Infosec is short for “information security.” It encompasses training in electronic intrusion and counterintrusion techniques as well as encryption and decryption.

Infosec is used both for hacking into electronic devices and mesh networks and for protecting them. See The Mesh chapter, p. 234, for more details.

Example (optional) specializations include Brute-Force Hacking, Decryption, Probing, Security, Sniffing, Spoofing.
