If multiple people want to log in to that network, they all use the same password. As we have discussed in previous posts, a password should be unique to a single user and a single account. Organizations using Enterprise-level WiFi security eliminate global shared passwords to the network. The Enterprise mode of WPA2 allows each user to create their own individual password and thus allows flexibility and centralized governance for domain accounts. It also prevents employees from sniffing all the traffic of other users on the network. But with Enterprise mode, no user can snoop on the online activities of another employee, reducing the information a malicious actor could collect.

A firewall filters the data of your network or device and only allows permitted traffic through. More advanced firewalls can even be configured to recognize attachments, filter URLs, and monitor DNS queries, allowing your company to prevent high-risk behavior.

It is also necessary to understand what firewalls cannot do. Just like malicious actors, they cannot recognize or decrypt encrypted traffic. Second, and perhaps more apparent, a firewall only protects the network or device it is enabled for.

Segmenting your network is the best way to prevent a full system failure from occurring if a malicious actor or malware make it past your firewall.

If your network is segmented, even if one server is compromised, the malware can be contained and the rest of your network can continue functioning.

Segmenting a network is a long, complicated process and it can take many different forms, from software-defined segmentation that divides and classifies different types of network traffic, to setting up separate physical networks for specific purposes. This process will need to be led by an IT security professional, but no matter how you decide to segment your network, there are some key steps your company should take. Network address translation NAT allows several computers on the same network to share one public IP address at the same time. If your company employs a dynamic NAT, you add another layer of protection between your internal network and the Internet, as the NAT will only allow connections that devices from your network initiates.

Next, you should maintain separate WiFi networks for your employees and guests.

It also gives network supervisors more control over who can access the servers and under what circumstances. In summary, the decision of how to segment your network should be based on the sensitivity of the data being handled and where the traffic is initiated from. A server that is accessible from the Internet should not be located on the same the network as a server containing sensitive data. With proper segmentation, even if a malicious actor gains control of one server, the other servers, and especially the servers holding sensitive data, should remain secure.

A firewall will protect your network, but today, more and more employees are working remotely.

The next step is to make sure you use the Enterprise mode of WPA2—also known as This is more complex to set up than a standard WiFi network, but it offers several important security advantages, the most important of which are the elimination of shared passwords and WiFi snooping. Personal WiFi networks generally have one password. If multiple people want to log in to that network, they all use the same password. As we have discussed in previous posts, a password should be unique to a single user and a single account.
