Internet connection is vital in today’s world so we can not deny the fact that we have to use the Internet in every area of our life. Although there are multiple ways to use the Internet, a Wifi connection is preferable when there are several devices and one Internet connection. It is practical to use Wifi connections in houses, companies, and other organizations. When Internet and Wifi usage is this much common, security breaches are unavoidable.
Many people think that passwords are sufficient to provide security. But they are wrong. There are multiple third-party applications that can crack even the most robust passwords. First, you need to recognize that passwords are not adequate to police the whole Wifi connection. So, other Wifi security methods must be considered to avoid any breach. Nobody wants to share their Wifi with unpermitted users. Sharing a single Wifi connection with many users means slow connection, lower performance, and of course high bills.
Constant Password Changing for Protection
As an Internet user, you should know which devices are connected to your Wifi and whether they are authorized or not. After that, you need to know how to restrict their access and block them from your Wifi. For beginner thieves, changing your router’s passwords continuously may be effective. Even if they obtain or anticipate your password, you can kick them off by changing your password. But it is not the same for professional hackers or more experienced malicious people. They do not care whether you change your password or not. They can simply find a way to sneak into your Wifi. If you are looking for a more comprehensive and permanent way to protect your Wifi from unauthorized devices, take a glance at the listed below.
How to Avoid Unauthorized Devices on Your Wifi Network
Create a Blacklist
Creating a Blacklist is an efficient way to block devices from your router. You can use your control panel or access point dashboard to filter devices. By deciding on which device has permission and which does not, you can eliminate unauthorized devices connected to your Wifi. When you find an unrecognized device, you can add it to the Blacklist and the device will be blocked until you give it permission. So you do not need to worry about the same devices again and again.
DNS Filtering Service
When talking about adding unauthorized devices to the list and blocking them forever, it may seem easy to operate. But, it is not as convenient as it seems. To create successful and protective lists, you need other tools such as filtering servers. You may have heard of the Domain Name System (DNS) which helps users to access websites without using IP addresses. Since computers use IP addresses and they can not understand words, it is quite hard for users to remember complicated IP addresses that consist of digits. Thanks to the Domain Name System, user words are converted into IP addresses and computers can understand what users mean and redirect them to the proper website.
But there are some concerns about DNS security. Hackers and other malicious parties try to hack users by using DNS. They sometimes take advantage of the typo. They detect the most common typos made by people in a rush such as Fcebook instead of Facebook. They set up a fake website that has the Fcebook domain. When people make a typo and type Facebook, they are redirecting to a fake site that is full of malware, software, or phishing threats. To protect yourself and especially your organization from these kinds of detrimental situations, DNS filtering service is an outstanding method.
Some of the DNS filtering services have content filtering features. This feature enables organizations to determine filters such as adult content, violence, terrorism, or even social media. Due to this filtering, managers can decide on which content will be accessible to users. There are also categorizing methods that DNS filtering service offers. This categorizing tool mainly focuses on preventing user access to determined malicious websites that certainly have malware, ransomware, and phishing links.
DNS filtering is more secure and effective in comparison with MAC address filtering. Mac addresses can sometimes be spoofed or modified. To provide total protection on your Wifi, DNS filtering services are highly recommended. If you are an organization that has a relaxed approach to Wifi security, blacklisting is a good way to do it. The weak point of blacklisting is it is impossible to detect all threats in advance. Non-included threats can affect your network even if you have a Blacklist. On the other hand, you can give it a try by whitelisting. It is contrary to blacklisting and means to create a list consisting of authorized and trustworthy websites. By doing this, you can narrow down the possibilities.
MAC Address Filtering
MAC, Media Access Control Address is a number that identifies devices on the network. MAC addresses are unique and no device in the world has the same MAC address. They are manufactured differently. Differing from IP Addresses, MAC addresses are about the hardware.
To perform MAC Address Filtering, you need to log in with your credentials to the dashboard. Then you should click the MAC Filtering option or similar command describing it. If the default situation is disabled, you need to switch it to enabled. Then you will see the MAC list on your computer. You can add or revoke MAC addresses to your router. Although it is an acceptable way to provide Wifi security, it is not practical all the time. Especially for extensive organizations, filtering devices in this way can be troublesome.
The importance of Wifi security is indisputable so we can say in a sure way that further protections should be taken. Even if you use the Internet for only personal reasons, you need to pay attention to your security for your interests. From the organizations’ point of view, Wifi security and DNS filtering should be the main concern and they should adopt their network to the latest verified methods.You may also like:
