+
+---
+
+### 4. Cisco Meraki MX
+- **Models Covered**: Meraki MX64, MX84, MX100, MX250
+- **Throughput**:
+  - **Firewall Throughput**: Up to 4 Gbps
+  - **VPN Throughput**: Up to 1 Gbps
+- **Concurrent Sessions**: Up to 2,000,000
+- **VPN Support**:
+  - **Protocols**: Auto VPN (IPSec), L2TP over IPSec
+  - **Remote Access VPN**: Client VPN (L2TP over IPSec)
+- **NAT Features**:
+  - **1:1 NAT, 1:Many NAT**
+  - **Port forwarding, and DMZ host**
+- **Security Features**:
+  - **Threat Defense**: Integrated intrusion detection and prevention (IDS/IPS)
+  - **Content Filtering**: Native content filtering, categories-based
+  - **Access Control**: User and device-based policies
+- **Deployment**:
+  - **Cloud Managed**: Entirely managed via the cloud, simplifying large-scale deployments and remote management.
+  - **Zero-Touch Deployment**: Fully supported
+- **Special Features**:
+  - **SD-WAN Capabilities**: Advanced SD-WAN policy-based routing integrates with auto VPN for dynamic path selection.
+
+### 5. SELinux (Security-Enhanced Linux)
+- **Base**: Linux Kernel modification
+- **Main Use**: Enforcing mandatory access controls (MAC) to enhance the security of Linux systems.
+- **Operation Mode**:
+  - **Enforcing**: Enforces policies and denies access based on policy rules.
+  - **Permissive**: Logs policy violations but does not enforce them.
+  - **Disabled**: SELinux functionality turned off.
+- **Security Features**:
+  - **Type Enforcement**: Controls access based on type attributes attached to each subject and object.
+  - **Role-Based Access Control (RBAC)**: Users perform operations based on roles, which govern the types of operations allowable.
+  - **Multi-Level Security (MLS)**: Adds sensitivity labels on objects for handling varying levels of security.
+- **Deployment**:
+  - **Compatibility**: Compatible with most major distributions of Linux.
+  - **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.
