Organizations Are Very Concerned About The Intrusion Into Corporate Networks, And Unfortunately, This Concern Has Now Reached Home Networks. 

Organizations and users use various mechanisms to secure wireless networks to prevent hackers from accessing them. However, various factors make wireless networks vulnerable to hacking, including poorly secured passwords and incorrect configuration.

Of course, we should not forget the existence of hacking tools that are constantly updated to disrupt security mechanisms.

Some users and organizations believe that VPNs can implement a robust security mechanism around networks. However, some basic steps to secure networks should not be overlooked. Solutions that increase the Security of WiFi networks make it harder for Security hackers to access wireless networks.

Changing the router and network passwords is not a complicated task. You can do so by following simple instructions at different time intervals. Still, before doing so, we must improve our network security information.

Several basic security protocols exist for securing wireless networks, the first of which is the WEP protocol.

This protocol has been used by users and security companies for more than two decades as a security mechanism, although it is no longer usable. After WEP, the WPA algorithm was introduced.

The above algorithm performed better than WEP, but over time, it was replaced by WPA2, the most secure protocol for encrypting WiFi networks.

It should be noted that the WPA3 algorithm is offered as an alternative to WPA2. However, most routers currently used by users do not support this security feature, and there is still time for a complete replacement for WPA2.

Now that you have a brief overview of cryptographic algorithms, it’s time to discuss ways to secure WiFi networks.

To Improve The Security Of Wi-Fi Network

1. Go to the modem or router settings page

In the first step, go to the router settings page. To do this, you must enter the router address, which in most cases is http://192.168.1.1. Next, enter the above address in the browser bar and enter the username and password in the fields that appear to access the router administration page.

2. After entering the settings page, depending on your router, click on the Wireless Settings option and change the password in the Password field.
3. On the WiFi settings page, another option called Security allows you to select the Security algorithm. We suggest choosing the WPA / WPA2 option and the ASecurityption algorithm in the Encryption field.

2. Find anonymous connections

If you are in a residential or building complex with several companies around you, you need to identify the devices connected to the router. There are two ways to do this.
First, go to the router settings page or use a device within the WiFi network. In the first case, you will see a list of devices connected to the router on the main router settings page after entering the router settings page. The figure below shows this.

The second method uses Fing Network Scanner and Net Analyzer Lite software. Fing is provided for the Android operating system and shows detailed information about devices connected to WiFi networks.

3. Disable the WPS router

We recommend turning off the router’s WiFi feature to maintain network security. Most attacks on WiFi networks occur due to bugs in WPS.

4. Go to filtering McAddresses

It is a good idea to specify the location of the devices to be connected to the router for the router and to filter other devices.

5. Use complex passwords

Try to use passwords that are more resistant to pervasive search attacks.

6. Do not worry about hiding the network SSID

Some users think that hiding the SSID of the network is a way to deal with hackers, and if you do this, you will encourage hackers to come to hack the network more.

7. Update the router or modem firmware

The router software, like the operating system of computers, must be updated. However, unlike computer operating systems, routers’ operating systems do not update automatically, so you must manually update the router’s firmware.

8. Change the default IP login to the router admin page

Changing the router’s default address can significantly improve WiFi network Security. To change the modem’s IP address, first, enter the router settings page, go to the Network section, and select the LAN option.
Then, enter the desired IP address and click the Save button to apply the changes. Note that depending on your router, the option to change the IP address may be elsewhere.

9. Activate the router firewall

Some routers are equipped with firewalls that users must activate. For example, D-Link modems provide users with good firewall capabilities. Follow the steps below to access the security features of various routers similar to the D-Link router:

First, enter the router settings, click the Advanced tab, and select Firewall from the list on the left. Then, on the page above, enable the Enable Attack Prevent option to activate the security mechanisms to prevent the attack.

Then, enable the Icmp Echo option. The above option is related to ping operations. Ping is used to determine the network’s status, but hackers can use this feature to send large volumes of packets. Another important option is Fraggle.

In a Fraggle attack, continuous heavy traffic is sent over a network using the UDP protocol, consuming the network bandwidth and router operating capacity entirely.

Another important field you need to activate is called Echo Chargen. Activating the above option prevents endless loops.

IP Land prevents the successful implementation of Layer 4 attacks. In this model, the same sender and receiver address attacks are used. A port scan is a solution based on hackers running a service on the network to obtain information about all network ports.

TCP Flags prevent the implementation of attacks that send heavy, repetitive traffic to networks. Enabling this option will prevent the successful implementation of TCP DoS or network malfunction.

10. Use a virtual private network.

A virtual private network is a network in which information is transmitted over a public network, such as the Internet, but remains private through the use of cryptographic algorithms and authentication. It is mainly used to establish connections between different branches of companies or remote activities.

A virtual private network must consider various factors, such as Security, reliability, and work management.
Nevertheless, using a virtual private network has several benefits for an organization, including expanding the geographical area of ​​communication, improving Security, reducing operating costs compared to traditional methods such as WAN, and reducing the time remote users take to send and carry iSecurityon.

Improved productivity, simple correlation, and so on. Virtual private networks cost less to implement and use than networks implemented with leased lines. Due to their structure, adding and subtracting nodes or local area networks to a virtual private network is possible at a lower cost.

If the private network topology needs to be changed, the network need not be restarted physically; the network correlation can be changed in software.
