Protecting Your Small Business Network

An unmanaged switch is a network switch that does not require any configuration and operates out of the box. It is designed to be plug-and-play, which means you can simply connect your devices to the switch and start using them immediately.

When it comes to protecting your small business network, an unmanaged switch can be a useful tool to ensure the security of your data and devices. Here are some security considerations to keep in mind when using an 8-port unmanaged switch:

  • Physical security: Make sure that the switch is located in a secure area and that unauthorized personnel cannot access it. This can be achieved by locking the room or cabinet where the switch is installed.
  • VLANs: If you have different departments within your organization, you can use VLANs (Virtual Local Area Networks) to separate their traffic. This can help prevent unauthorized access to sensitive data.
  • Port security: You can enable port security on your unmanaged switch to prevent unauthorized devices from connecting to your network. This can be done by configuring the switch to only allow devices with specific MAC addresses to connect to it.
  • Firmware updates: Although unmanaged switches do not require any configuration, they still require firmware updates to fix security vulnerabilities. Make sure to check for firmware updates regularly and apply them when available.
  • Disable unused ports: If you have unused ports on your switch, it's a good idea to disable them to prevent unauthorized access.
  • Use strong passwords: If your unmanaged switch has a web interface for configuration, make sure to use strong passwords to prevent unauthorized access to the configuration settings.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
