Episode 66 — Mandatory Access Control and Software Firewalls
In this episode, we examine the Mandatory Access Control (MAC) model and its role in enforcing strict, label-based security policies in cloud systems. MAC assigns classifications to both subjects (users, processes) and objects (files, resources) and enforces access based on these labels, removing discretionary control from end users. This model is commonly used in high-security or compliance-driven environments, where consistent enforcement is critical. We also cover software firewalls, which operate at the host level to control traffic in and out of specific systems, complementing network firewalls by adding another layer of defense.
We also discuss deployment considerations, such as the performance trade-offs of MAC enforcement, the importance of firewall rule maintenance, and integration with automated configuration management. For the Cloud+ exam, you’ll need to know how to apply these controls in both security planning and troubleshooting scenarios.
