Security Landscape

The term "Security", especially in the Cybersecurity context, is broad and confusing. Terms like "NGFW" and "UEBA" are thrown around - sometimes without context. So here I lay out the security landscape, but with focus on Network Security - the old guard and hence has the highest market share of roughly 40%. In this drawing, I will try to show Network Security, and how it is peers to other important security measures such as Application Security and Endpoint Security, and where "NGFW" and "UEBA" fit.

Note that some cybersecurity practioners might categorize IDS and IPS as part of a firewall - and that is completely ok. Firewalls are primarily about controlling access to networks. IDS focuses on detecting and alerting on suspicious activities. IPS combines detection with proactive blocking capabilities to prevent attacks. But for this blog, I purposely broke them apart because terms like "Gen 2 Firewall" and Gen 3 aka NG Firewall" and thrown around, and I wanted this diagram to make that easier to find.
