LANs or Local Area Networks connect computers and other devices in a limited area, such as a building or campus, allowing them to share data and resources. When you attach a wireless access point or router to your network, you are extending your LAN to anyone within WiFi signal range, so you have to make sure your wireless security is up to the challenge, and also that the sensitive parts of your network are protected even from those who may have your wireless password.
Hughes Technology emphasizes robust security in all our services, ensuring that our clients, whether they operate a business or a home office, can securely provide wireless internet access while maintaining network integrity. We achieve this through two primary methods: VLANs (Virtual Local Area Networks) and physically separate LANs (Local Area Networks). Both approaches offer distinct advantages and are suited for different client needs.
The Problem: Non-Segmented LANs:
- Without segmentation, all devices on the LAN can potentially access all resources. This poses a significant risk, especially for sensitive systems like POS terminals and accounting computers.
- Malware, viruses, or a breach on one device can easily spread across the entire network.
The Solution: LAN Segmentation
1. VLANs:
- Basics: A VLAN is a subnetwork within a LAN. It groups together a collection of devices on one or more LANs to create a virtual, segmented network. This segmentation is achieved through software rather than physical hardware.
- Similarities with Separate LANs: Like physically separate LANs, VLANs isolate network traffic. This isolation ensures that devices in one VLAN do not ‘see’ the devices in another, enhancing security.
- Differences: VLANs are more flexible and cost-effective compared to separate LANs. They allow for easy reconfiguration of network segments without the need for physical rearrangements.
- Best Suited For: VLANs are ideal for clients needing dynamic network configurations, those with limited physical space, or businesses looking for a cost-effective solution.
2. Physically Separate LANs:
- Basics: This involves setting up completely independent LANs, each with its own set of hardware like switches, routers, and cabling.
- Differences: This method offers a higher level of security since the networks are physically isolated. There’s no risk of software vulnerabilities affecting this separation.
- Best Suited For: Separate LANs are recommended for environments requiring maximum security, such as organizations handling sensitive data, or where regulatory compliance demands strict network segmentation.
Our Other Offerings For Business and Home-Office Clients
- VPN Access: Providing remote, secure access to the network.
- Tailored Firewall Configurations: Implementing advanced firewall rules to further secure network traffic.
In conclusion, the choice between VLANs and separate LANs depends on the specific needs and circumstances of the client. Hughes Technology also offers a range of complementary solutions to ensure a comprehensive, secure networking environment. Our approach is designed to cater to various business sizes and requirements, prioritizing security and efficiency in all our offerings.
