Learn to enhance Ubuntu system security through hands-on AppArmor profile creation in this comprehensive workshop from UbuCon Asia 2025. Discover how to protect your system from applications that may have excessive permissions by implementing mandatory access controls that define exactly what each application can and cannot do. Explore the fundamentals of AppArmor's security framework and understand how unrestricted applications can become attack vectors for system compromise. Master the process of analyzing current application permissions and identifying potential security vulnerabilities in your software stack. Build practical AppArmor profiles from scratch that restrict application access to only necessary files, network resources, and system capabilities. Practice testing and validating security profiles to ensure they effectively reduce attack surfaces while maintaining application functionality. Develop troubleshooting skills for refining and debugging AppArmor configurations when applications encounter permission conflicts. Apply real-world examples such as restricting an image viewer to only access specific file types like JPEG, JPG, and PNG files. Gain the expertise to systematically secure your Ubuntu applications through proper mandatory access control implementation and create robust security shields around potentially vulnerable software components.
