Study Notes
Networking Concepts and Technologies
- Demilitarized Zone (DMZ): A less secure network to allow direct access from the internet while protecting the main network.
- Fully Qualified Domain Name (FQDN): Combines the computer name and domain name to provide an exact address for servers on the internet.
- HomePNA Technology: Utilizes existing telephone lines for networking; requires a HomePNA Adapter for setup.
- HomePNA Adapter: Connects all telephone jacks within a building to create a network.
- Internet Connection Firewall (ICF): Software that blocks unauthorized access to a network.
- Internet Gateway Device Discovery and Control (IGDDC): Mechanism to identify and manage network gateway devices like routers.
Storage and Security
- Network Attached Storage (NAS): Centralized file storage system that requires minimal administrative work.
- Packet Sniffer: Tool for capturing and analyzing data packets traveling over a network.
- Port Forwarding: Router setting that directs incoming traffic on specified ports to designated computers or servers.
- Port Triggering: Monitors outgoing traffic to open specific incoming ports as needed.
Communication and Connectivity
- Powerline Communications (PLC): Technology that turns electrical wiring into a networking medium.
- Proxy Server: Acts as an intermediary for requests from clients seeking resources from other servers.
- Single Port Forwarding: Similar to port forwarding but specifies one IP address rather than multiple.
- Virtual Private Network (VPN): Secures internet data by creating a private tunnel between users and destinations.
Internet Sharing and Hotspot
- Internet Connection Sharing (ICS): Facilitates the sharing of internet connectivity, files, folders, and printers among devices.
- Mobile Hotspot: A portable device enabling multiple users to connect to the internet, functioning off smartphones, tablets, or laptops.
- Wireless Networking: Popular for SOHO environments; requires secure configuration changes and offers two encryption types.
Encryption and Security Practices
- Encryption Types: Advanced Encryption Standard (AES) and Temporal Key Encryption Protocol (TKEP) used for securing wireless networks.
- Dedicated Computer: Specifically used for file storage and sharing, often configured with RAID for reliability.
- Cloud Service Characteristics: Include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.
- Cloud Infrastructure Models: Differentiates between private, public, community, and hybrid cloud settings.
Networking Errors and Troubleshooting
- Network Not Found Reasons: Includes incorrect path, non-existent connection/location, or permission issues.
- Remote Desktop vs. Remote Assistance: Remote Desktop provides full control without the need for user presence, while Remote Assistance helps users with partial access.
- Port Numbers: Remote Desktop (3389), Remote Assistance (3389), HTTP (80), and HTTPS (443).
Configuration Techniques
- Port Forwarding vs. Single Port Forwarding: Port Forwarding allows addresses from the whole local area; Single Port Forwarding focuses on a specific IP.
- Typical IPv4 Address for ICS: Commonly assigned as 192.168.0.1.
- Securing Routers: Essential practices include modifying default credentials, enabling MAC address filtering, and disabling SSID broadcasting.
- Local Group Security Editing Tool: Secpol.msc is the correct utility for managing local group policies.
