What is Infrastructure Security?
By Cyber Tool Stack Editorial TeamUpdated
Definition
An umbrella term for securing the layers applications run on — networks, servers, containers, and cloud services — as opposed to the application code itself. This map deliberately splits that umbrella by where each control lives: Network & Perimeter (traffic and the perimeter), Cloud Security (cloud infrastructure and container/Kubernetes security), and Security Operations (vulnerability management).
