Linux Server Security Beyond the Firewall

We look at why traditional perimeter security fails in modern Linux environments and how mandatory access control systems like SELinux and AppArmor shift the defense from blocking external traffic to restricting internal process behavior. Lucas walks through a specific incident where a compromised web service was contained because of strict MAC policies, while Luna explores the operational friction this creates for sysadmins who are used to root-level freedom. We cover the difference between discretionary and mandatory access controls, how to read audit logs when something gets blocked, and practical steps to move from permissive to enforcing modes without breaking production services. #FexingoBusiness #BusinessPodcast #Technology #LinuxServer #Sysadmin #Bash #ServerEngineering #SELinux #AppArmor #MandatoryAccessControl #Cybersecurity #SystemD #AuditLogs #ContainerSecurity #DevOps #CloudInfrastructure #ServerHardening #ITOperations Keep every episode free: buymeacoffee.com/fexingo
