Course Description

  
This advanced security course takes a deep dive into the complexities and nuances of SELinux. The course discusses security threats posed to today’s computing resources and mitigating them through network and host protections. Students will review SELinux technology through understanding SELinux’s goals, how it has evolved including its features and limitations.
 
Students will gain hands-on experience in working with SELinux modes, virtualization, and container security. The core of the course is learning and understanding SELinux policy through, choosing, managing, and studying policy examples. Once students have an understanding of the SELinux policy the course will cover writing policy modules. The course is capped with multiple discussions on case studies that explore building SELinux policies. This SELinux course covers one of the major challenge faced by administering SELinux, SELinux troubleshooting.
Course Length: 3 Days
Course Tuition: $2590 (US)

Linux Unix Uses & Stats

Linux Unix is Used For:
Desktop Mainframe Computers Mobile Devices Embedded Devices

Pros
Performance:
Linux supports many efficient tools and operates them seamlessly. Because it's architecture is lightweight it runs faster than both Windows 8.1 and 10. 
 
Security:
Because Linux is an open-source software,  anyone can contribute code to help enhance the users’ experience i.e., adding features, fixing bugs, reducing security risks, and more.
 
 
Software Development:
The terminal in Linux is a *wild card*. You can do almost anything with it. This includes software installation, application and server configurations, file system management, and etc.
 
Large-scale:
Open-source projects benefit from having an attentive community. As a result, Linux is more secure than Windows. Instead of installing anti viruses to clean malware, you just have to stick to the recommended repositories. 
 
Efficient: 
Developers have the convenience of running servers, training machine learning models, accessing remote machines, and compiling and running scripts from the same terminal window. 
 
Free: 
Linux is free (you can put it on as many systems as you like) and you can change it to suit your needs.
Cons
Learning Curve: 
Linux is not for everyone, there is a learning curve in switching to Ubuntu. To actually learn Linux efficiently would take a user one to several years.
 
No Tech Support:
Unlike Windows, there isn’t a dedicated tech support, so getting help for things is up to you. 
 
Designer Compatabilty:
Linux is not as user friendly as Windows or as ‘straight out of the box design’ As an example for design choices, Adobe hasn’t released any of its products to Linux users. So it’s impossible to run them directly. The Ubuntu alternative is a free software called GIMP. 
 
Gaming Capabilities: 
Most games aren’t available in Linux. But that’s not to say you can’t make it happen, it's just not as easy.
