What's the main difference when comparing AppArmor & SELinux?
 AppArmor and SELinux are both security modules in the Linux kernel that provide mandatory access control (MAC) for enhancing the security of a system. While both have similar goals, they differ in their implementation and configuration philosophy. Here are the main differences between AppArmor and SELinux:

1. Policy language and structure:
AppArmor uses a simple policy language based on plain text files with a clear and easy-to-understand syntax. Policies are organized around profiles, which are assigned to specific applications or groups of applications. Each profile defines the permissions and resources that the assigned application can access.

SELinux, on the other hand, uses a more complex policy language based on rules written in a domain-specific language. Policies are organized around types, which are assigned to processes, and roles, which are assigned to users. SELinux policies define the rules governing the interactions between these types and resources.

2. Ease of use and configuration:
AppArmor is generally considered easier to configure and manage than SELinux. AppArmor profiles can be created and modified with simple text editors, and there are tools available to assist in generating profiles. AppArmor also has a more permissive default policy, allowing applications to run with fewer restrictions.

SELinux can be more challenging to configure and manage, as its policies are more complex and require a deeper understanding of the
AppArmor and SELinux (Security-Enhanced Linux) are both Mandatory Access Control (MAC) systems, designed to provide an additional layer of security to Linux systems. While they share similar goals, there are significant differences in their approaches, architectures, and implementations.

**Main differences:**

1. **Architecture**:
	* AppArmor: Path-based, which means it focuses on the path of the executable or file being accessed. It uses a simpler, more intuitive approach, with a smaller kernel patch.
	* SELinux: Label-based, which means it focuses on the security context of the process or file being accessed. It uses a more complex, fine-grained approach, with a larger kernel patch.
2. **Policy management**:
	* AppArmor: Policies are defined using simple, human-readable configuration files, which are easy to understand and manage.
	* SELinux: Policies are defined using a more complex, XML-based language, which can be challenging to understand and manage.
3. **Default behavior**:
	* AppArmor: Defaults to a " deny-all" approach, where access is denied unless explicitly allowed.
	* SELinux: Defaults to an "allow-all" approach, where access is allowed unless explicitly denied.
4. **Performance impact**:
	* AppArmor: Generally considered to have a lower performance impact due to its simpler architecture and fewer kernel modifications.
	* SELinux: Can have a higher performance impact due to its more complex architecture and additional
