Episode 52 — Cloud Network Services — Stateful/Stateless Firewalls and WAF
This episode explains how network security appliances and services operate in cloud environments. We begin with stateful firewalls, which track active sessions and allow or block traffic based on the state of connections, and contrast them with stateless firewalls, which evaluate each packet individually without session context. We also cover web application firewalls (WAFs) that protect applications from common exploits like SQL injection, cross-site scripting, and request forgery. The focus is on deployment strategies, integration with cloud-native services, and tuning for performance and false-positive reduction.
We also explore how these services combine to form layered defenses in multi-tenant or multi-cloud environments. In the Cloud+ exam, you may be asked to choose or configure the correct service based on traffic type, security requirements, and compliance mandates. Mastering these distinctions ensures your designs and responses are both technically sound and exam-ready. Produced by BareMetalCyber.com, which offers more prepcasts, books, and cloud firewall configuration resources.
