In the age of digital technology, wifi networks have become an indispensable part of business operations. However, the wifi network is also a weak point that is vulnerable to attacks, putting important business data at risk of being stolen. So, what is the solution for business wifi security? In this article, we will learn about the most effective security solutions today.

Risks in corporate wifi network security

Business wifi networks are an attractive target for attackers. They can use weakly secured wifi networks to access sensitive business data, such as customer information, financial information or business secret information. Here are some main risks in business wifi network security:

Weak password

Weak passwords are the most common cause of wifi network attacks. Attackers can easily guess weak passwords or use brute-force tools to break passwords.

Poor encryption

Encryption is an important security measure that helps protect data when transmitted over a wifi network. If the wifi network is not encrypted, attackers can easily read the data being transmitted.

Firewalls are ineffective

A firewall is a device or software that helps protect a wifi network from unauthorized access from the outside. If the firewall is not configured properly, attackers can easily bypass the firewall and access the wifi network.

Ineffective access management

Access management helps control access to wifi networks, allowing only those with valid access rights. If access management is not done properly, attackers can easily spoof their identities and gain access to the wifi network.

The devices are not secure

Insecure devices, such as laptops or smartphones, can be infected with malware. Malware can be used to steal data or gain unauthorized access to wifi networks.

Secure network solutions for businesses

Below are some secure network solutions for businesses:

• Encryption: Encryption is a basic and important security measure that helps protect data when transmitted over a network. Encryption prevents attackers from reading the data, even if they can access the network.
• Firewall: A firewall is a device or software that helps protect a network from unauthorized access from the outside. A firewall will block unauthorized access, such as access from untrusted IP addresses or domains.
• Access management: Access management helps control access to the network, allowing only those with valid access rights. Access management can be accomplished using methods such as two-factor authentication, access control lists (ACLs), or access management (IAM).
• Two-factor authentication (2FA): Two-factor authentication is an additional layer of security that requires users to enter two different factors to access an account or network. The second element is usually a code sent to the user’s mobile phone.
• Virtual Private Network (VPN): A Virtual Private Network (VPN) allows users to securely access a corporate network remotely. A VPN will encrypt data traffic between the user’s device and the business network.
• Network monitoring: Network monitoring helps businesses detect unusual activities on the network, such as cyber attacks. Network monitoring can be performed using network monitoring tools such as intrusion detection systems (IDS) and intrusion prevention systems (IPS).
• Employee training: Training employees on cyber security measures is important. Employees should be taught how to use strong passwords, avoid visiting insecure websites, and how to detect and remove malware.
• Update software regularly: Manufacturers often release software updates to patch security vulnerabilities. Businesses should update software regularly to protect systems from cyber attacks.
• Use secure devices: Businesses should use secure devices, such as devices certified to meet wifi security standards. These devices are often designed with advanced security features to help protect systems from cyber attacks.
• Comply with regulations: Businesses should comply with network security regulations. These regulations can help businesses ensure that their systems are secured according to certain standards.

Wifi security measures for businesses

To avoid security risks, businesses need to apply effective wifi security measures, as follows:

Block remote access feature

This feature allows users to remotely manage wifi devices, but can also be exploited for unauthorized access. Therefore, businesses should block this feature on wifi devices and only allow access from the internal network.

Enable encryption

This feature helps encrypt data transmitted and received via wifi, to prevent it from being monitored or stolen. Businesses should choose the safest WPA encryption protocol today, WPA2 or WPA3 security, and set a strong password for wifi.

Filtering feature by MAC address

This feature allows only devices with a pre-registered MAC address to connect to wifi. This is an extra layer of security to limit wifi connections of unknown or unwanted devices.

Firewall security

Firewalls are an important tool to control and filter packets coming in and out of wifi. Businesses should install and configure firewalls on wifi devices or routers, to prevent attacks from outside or from devices connected to wifi.

Hide network connection name display (SSID broadcast)

This feature allows you to hide the name of the wifi from the list of available wireless networks, to reduce the possibility of detection and connection by bad guys. Businesses can hide the wifi name on the wifi device or router, and only enter the wifi name when they want to connect.

Wifi is a popular and convenient wireless technology, but also has many potential security risks. If not well protected, wifi can be stolen by bad guys, infiltrate the network or cause denial of service attacks. By applying wifi security measures, businesses can increase the safety of their wireless network systems, and protect important information.
