- **Management Tools**: Various tools available for policy management, including `semanage`, `setroubleshoot`, and graphical interfaces like `system-config-selinux`.
- **Advantages**:
- **Granular Control**: Provides very detailed and customizable security policies.
- **Audit and Compliance**: Excellent support for audit and compliance requirements with comprehensive logging.

Here are the additional fact sheets for AppArmor, a Linux security module, and typical VPN technologies used within Linux environments:
---
### 6. AppArmor (Application Armor)
- **Base**: Linux Kernel security module similar to SELinux
- **Main Use**: Provides application security by enabling administrators to confine programs to a limited set of resources, based on per-program profiles.
- **Operation Mode**:
- **Enforce Mode**: Enforces all rules defined in the profiles and restricts access accordingly.
- **Complain Mode**: Does not enforce rules but logs all violations.
- **Security Features**:
- **Profile-Based Access Control**: Each application can have a unique profile that specifies its permissions, controlling file access, capabilities, network access, and other resources.
- **Ease of Configuration**: Generally considered easier to configure and maintain than SELinux due to its more straightforward syntax and profile management.
- **Deployment**:
- **Compatibility**: Integrated into many Linux distributions, including Ubuntu and SUSE.
- **Management Tools**: `aa-genprof` for generating profiles, `aa-enforce` to switch profiles to enforce mode, and `aa-complain` to set profiles to complain mode.
- **Advantages**:
- **Simplicity and Accessibility**: Less complex than SELinux, making it more accessible for less experienced administrators.
- **Flexibility**: Offers effective containment and security without the extensive configuration SELinux may require.
### 7. Linux VPN Technologies
- **Common Solutions**:
- **OpenVPN**: A robust and highly configurable VPN solution that uses SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls.
- **WireGuard**: A newer, simpler, and faster approach to VPN that integrates more directly into the Linux kernel, offering better performance than older protocols.
- **IPSec/L2TP**: Often used in corporate environments, IPSec is used with L2TP to provide encryption at the network layer.
- **Throughput and Performance**:
- **OpenVPN**: Good performance with strong encryption. Suitable for most consumer and many enterprise applications.
- **WireGuard**: Exceptional performance, particularly in terms of connection speed and reconnection times over mobile networks.
- **Security Features**:
- **OpenVPN**: High security with configurable encryption methods. Supports various authentication mechanisms including certificates, pre-shared keys, and user authentication.
- **WireGuard**: Uses state-of-the-art cryptography and aims to be as easy to configure and deploy as SSH.
- **Deployment**:
- **Configuration**: Both OpenVPN and WireGuard offer easy-to-use CLI tools and are supported by a variety of GUIs across Linux distributions.
- **Compatibility**: Supported across a wide range of devices and Linux distributions.
- **Advantages**:
- **OpenVPN**: Wide adoption, extensive documentation, and strong community support.
- **WireGuard**: Modern cryptographic techniques, minimalistic design, and kernel-level integration for optimal performance.
