Instead you should consider WPA2-Enterprise, which, in addition to other benefits, eliminates the shared passphrase. While the technical specifics behind this type of deployment are beyond the scope of this post, this article provides a nice overview: Wireless Security in the Enterprise: Deploying WPA2-Enterprise. A much better option is to use certificates; Microsoft echoes this sentiment:. It is recommended that you use a certificate-based authentication method for all network access methods that support the use of certificates.
Using a certificate-based EAP means only users, machines and mobile devices with properly configured certificates will be able to access your Wi-Fi networks. Another benefit is that, unlike password-based schemes which really only authenticate the user, certificates can be issued to the machines themselves to help prevent rogue device access e.
Certificates fit right into this scenario. By leveraging Group Policy and a RADIUS server, you can push out certificates to client computers and create policies that will automatically place devices into their appropriate network. If you are already using it, are you using certificates to strengthen authentication and secure access to your wireless networks?
Why or why not? Onboarding clients, such as those offered by SecureW2, eliminate the confusion for users by prompting them with only a few, simple steps designed to be completed by K age students and up. The result is a properly configured WPA2-Enterprise network with Check out this informative piece on onboarding! A PKI enables organizations to use x.
An effective PKI significantly bolsters network security, allowing organizations to eliminate password-related issues with certificate-based authentication.
Once the PKI is configured, network users can begin enrolling for certificates. This is a challenging task to complete, but organizations that have used an onboarding client have had the most success distributing certificates.
SecureW2 is able to provide all the tools needed for a successful PKI deployment and efficient distribution of certificates. After equipping their devices with a certificate, users are ready to be authenticated for the wireless network. Enterprises with managed devices often lack a unified method of getting devices configured for certificate-driven security. Allowing users to self-configure often results in many misconfigured devices, and leaving the task to IT can be mountainous.
Configuring dozens, or sometimes even hundreds, of devices manually for a secure WPA2-Enterprise network is often considered too labor-intensive to be worthwhile. In one fell swoop, these gateways allow an IT department to configure managed devices from any major vendor for certificate-driven network security.
Backed by AWS, it delivers high availability, consistent and quality connections, and requires no physical installation. Once fully integrated, the certificate-based network is ready to begin authenticating network users. Instead of making policy decisions based on static certificates, the RADIUS makes runtime-level policy decisions based on user attributes stored in the directory.

Simplifying WPA2-Enterprise and This could be a home or small office. As a way to restrict casual users from joining an open network when unable to deploy a captive portal. This could be a coffee shop or guest network. As an alternative network for devices not compatible with An example being game consoles in a student dorm. WPA3-Enterprise A significant improvement that WPA3-Enterprise offers is a requirement for server certificate validation to be configured to confirm the identity of the server to which the device is connecting.

The RADIUS remote authentication dial-in user service server doing the authentication is the authentication server , and the device at the AP, such as a laptop or smartphone, is the authenticator. Users are assigned login credentials to enter when connecting to the network; they don't see the actual encryption keys, and the keys aren't stored on the device.
This protects the wireless network against terminated employees or lost devices. The authentication is port-based so that when a user attempts to connect to the network, communication is allowed through a virtual port for the transfer of login credentials. If authentication is successful, encryption keys are securely passed out and the user receives full access. Although there are more than ten EAP types , these three are the most popular:.
Consult your hardware and software manufacturers for guidance. There's no end to the task of protecting against data theft and managing risk and compliance in the wireless enterprise. Key challenges in wireless security vary widely and continue to evolve because every enterprise is different. Some IT teams struggle with the impact of BYOD bring your own device while others seek ways to allow guest access without compromising security of mission-critical systems. The IEEE In addition, major platform vendors often provide ways to assist in the management of security measures, helping to reduce the resources needed and overall time spent on IT management.
Wi-Fi continues to grow and adapt to business needs. While 2. Wireless network products using the Wi-Fi brand may operate in the 2. The Wi-Fi Alliance is in the early stages of developing a certification program known as Suite B for a set of encryption methods focused on encryption, key exchange, and related technologies for securing ultra-sensitive security domains.
Suite B will likely be the next level of wireless protection. Make sure your group has adopted the latest technologies described here.
