The Building blocks for the knowledge of each topic.
They live somewhere between “just getting started” and “fully proficient.” They’re not the finish line, but they give you the footing to keep running.
For example, you don’t need to specialize in networking, but you should understand:
- Subnetting
- Routing
- Inter-networking concepts
- The OSI model
- How to perform and interpret a packet capture
- DNS fundamentals and basic analysis
The same applies across every functional pillar—from operating systems and scripting to cloud, security, and beyond.
A lack of fundamentals in any one pillar can quickly render a team member ineffective during dynamic and rapidly evolving situations. Conversely, no one person on the team should be, or can be, a cyber unicorn
Ideally, everyone will have a specialty they excel at in addition to a solid baseline in the fundamentals.
It should not be expected that every one completely master each pillar. The intent is to have a good understanding of them.
