Network Devices

Updated Jan 16, 2019 ·

Hubs​

Hubs are basic networking devices that broadcast data to all connected devices without distinguishing between them.

  • Connect multiple devices in a network, commonly found in home networks
  • Less intelligent compared to switches or routers

Switches​

Switches are networking devices that connect multiple devices within a local area network (LAN).

  • They direct data between devices within the network
  • Typically hidden in wiring closets
  • Each switch port connects to one end of a network cable

The cables run through conduits, connecting to Ethernet jacks (wall jacks) throughout the building.

WAPs​

Some devices connect to the network wirelessly via Wireless Access Points (WAPs). These WAPs are connected to switches and create Wi-Fi networks, sending and receiving signals to and from mobile devices.

For more information, please see WAPs.

Routers​

Routers are devices that direct data between different networks, ensuring it reaches its correct destination.

  • They connect LANs to the internet or other networks
  • They determine the best path for data to travel across networks
  • They often include firewall and network management features

Core routers act as the core of your network communication. They handle high-volume data packets and enable forwarding between the connected networks. They do not communicate with the external world, such as the internet.

Servers​

Servers are powerful computers that manage and deliver resources or services to other devices on a network.

  • Provides information to other computers on a network
  • Common types include web servers, email servers, print servers, database servers, and file servers
  • Secured differently than workstations

Endpoints​

Endpoints are the devices that act as the source or destination of network communication.

  • Ends of a network communication link
  • One end often at a server with a resource, the other end a client making a request
  • Can be servers, desktops, laptops, tablets, mobile phones, or other end-user devices

Network Sensors​

Network sensors are devices that continuously monitor network traffic to identify and report on anomalies and potential security threats.

  • Monitor network traffic and detect anomalies and potential threats in real-time
  • Collect data for analysis and reporting
  • Integrate with other security systems to automate alerts and responses

Jump Servers​

Jump servers, also known as "jump boxes," provide a secure and controlled environment for administrators to perform network tasks.

  • Serve as secure access points for admin tasks
  • Isolate administrative activities from regular network traffic
  • Log and monitor all administrative actions for auditing purposes
  • Usually host a range of tools and scripts for system administrators

Firewalls​

Firewalls are security devices that monitor and control network traffic based on predefined rules.

  • They block or allow traffic to protect networks from unauthorized access
  • Firewalls can filter both inbound and outbound traffic
