How to improve LAN and WLAN Performance and Security

When it comes to managing a Local Area Network (LAN) and a Wireless Local Area Network (WLAN), it’s crucial to prioritize both performance and security. After all, efficient communication and protected sensitive data is what every organization strives for. Here are a few expert tips that can help you achieve optimal LAN and WLAN security as well as performance:

Invest in a High-Quality Router

A top-notch router with features like firewall, VPN and inappropriate content controls can take your network performance and security to the next level! Choose a router that can manage the number of devices connected, has robust Wi-Fi signals and supports the latest security protocols.

Strengthen Password Policies

It’s crucial to have network access control in place! For the best LAN and WLAN security, direct your users to create strong passwords. These usually have upper and lowercase letters, numbers, and special symbols. Make sure they change them regularly as well to maintain your WLAN and LAN protection.

Use WiFi Encryption

The only way to stop unauthorized access and protect sensitive information on WLAN or LAN networks is to enable encryption. WPA2 or WPA3 encryption for your WLAN network will encrypt all transmitted data and prevent unauthorized access for your business or home.

Disable WPS (WiFi Protected Setup)

WPS puts your network security at risk. For better network protection it is best to disable it and use a strong password instead.

Disable SSID Broadcast

Also known as “beaconing,” if the network is password secured, others will be able to locate the SSID. By disabling SSID broadcast, you make it harder for cyber attackers to find your network. Your users can still connect by manually entering the SSID name and password but you will have superior network security.

Implement MAC Address Filtering

Why should you filter your MAC (Media Access Control)? MAC address filtering allows you to control which devices can connect to your network. This adds an extra layer to your network security as unauthorized devices will not be able to connect.

Use a Virtual Private Network (VPN)

You should take into account whether using a VPN is legal in your country, if it monitors your data and activity as well as if it adds more cost to your network connection. Sizwe IT’s qualified experts can advise you on what is best for your LAN or WLAN network. A VPN may be an option for additional network security as it creates a secure, encrypted connection between your device and the internet. It protects your sensitive information from unauthorized users.

Keep Software and Firmware Updated

Regular updates to your software and firmware can improve network performance and fix vulnerabilities in your network security. Don’t forget to update your router and devices too.

Monitor Network Traffic

Regular network monitoring helps you identify and prevent any potential network security threats. Keep an eye out for unusual patterns or amounts of traffic and act quickly to protect your network.

Segment Your Network

Segmenting your network into subnets can limit the spread of malware or malicious attacks, improve security, and make it easier to manage network traffic.

Use Network Access Control (NAC) Systems

NAC systems restrict access to your network based on predefined rules. This improves security and reduces the risk of data theft.

Implement Network Firewalls

Network firewalls act as a barrier between your internal network and the internet, preventing unauthorized access. They can block malicious traffic, prevent malware from spreading, and protect your sensitive information.

Use Antivirus Software

Antivirus software can detect and remove malware from your network. Make sure to scan your network regularly and keep the software up-to-date.

Educate Your Users

Regular training and education for your users can help them identify and prevent security threats. Encourage them to follow best practices such as using strong passwords and avoiding suspicious links.

Regular Backups

Regularly backing up your data can help you recover in the event of a data breach or cyber attack. Store your backups off-site in a secure location.

By following these tips, you can ensure that your LAN and WLAN networks are at their best! Regular monitoring and maintenance is key to preventing security breaches. Stay vigilant and always look for ways to improve the performance and security of your network.

In conclusion, a comprehensive strategy is needed to enhance LAN and WLAN performance and security. This advice can help you make sure that your network is working as quickly, safely, and stably as possible.
