Choosing the Right EAP Method: Enhancing Network Security

Network Image

If you know how vulnerable most networks are, you’ll do everything possible to protect your server.

Having a poor network or data system comes with many costs. So many computers are having a breakdown because of a vulnerable database. This has caused so much losses and led to several bankruptcies. 

So many industries prevail because they choose to implement optimal security on whichever network protocol they adopt.

How, then, can you choose the right EAP method? If you want to learn how to use the right protocol, this guide is for you. It explains the risks, benefits, and process of protecting your server in simple language.

Network security

What is EAP?

EAP stands for Extensibility Authentication Protocol. It uses a point-to-point standard for transmission and secures data between a network and a user’s device. It’s what you need for encrypted access to the internet and is highly effective for wireless networks.

A P2P connection serves best for connecting a device to the internet. An EAP uses this standard to avoid vulnerabilities. Such transmission has several authentication options like smart cards, certificates, public keys, etc.

This protocol helps to protect a network server so that only users with authentication can gain access. It helps limit the number of users on a computer, which, in turn, prevents network congestion.

It has a clear framework within networks and helps to utilize the internet with a faster and more secure connection. Organizations make the best of it by understanding its features and selecting the best method for their activities.

The Three Components of EAP

802.1x works best for an EAP. It is the best standard for a Local Area Network or a WLAN.

This authentication mechanism has three components:

The authentication database

–       The user’s wireless device

–       A wireless access point or authenticator

There’s more to choosing an EAP method for your enterprise. The inability to choose the right one will only lead to damage. It is best to know which option is best for all your operations.

EAP is a secure protocol between a client and an authenticated server. It transfers authenticated data between the user and the server. Organizations that wish to implement this protocol must identify which method is best for their operations.

How Does an EAP work?

Understanding how an EAP provides a network to a user’s device is critical in determining the best method. The basic steps involved in such transmission follow this framework:

–       A user requests immediate connection through an Access Point, sometimes called a transceiver.

–       The AP requests valid proof of identification from the user and transmits the data to an authentication server.

–       The server then asks for proof of the validity of the authenticated information.

–       Once the AP verifies the user’s identification proof, it returns the information to the server.

–       As soon as the process is completed, the user gets connected to the requested server using a secure network.

How to Choose the Right EAP Method

EAP methods vary depending on the extensibility approach. While some are under standard EAP, others are secondary. Below is an overview of the types of EAP methods and how they help to secure a network:

EAP-Transport Layer Security

This process is simple yet challenging to those with extensive WLAN. The user and server must use the duplicate certificates to initiate a connection. EAP-TLS is often useful for generating session-based and user-based Wired Equivalent Privacy (WEP). It is highly effective with a secure SSL tunnel.

EAP-Tunnel Transport Layer Security

Similar to EAP-TLS, this protocol is best applicable in a secure SSL tunnel. However, only the server needs the certificate. It is difficult to expose a user’s identity with this method.

Lightweight EAP

Enterprises often use LEAP for P2P connection and wireless networks. In this case, the server authenticates the user’s device. The client then responds with a hashed password. Once the process is complete, the client can request a server password.

Protected EAP

PEAP is a more secure protocol compared to LEAP. It uses an encrypted TLS tunnel (802.11 WLAN) so that the user can authenticate through it.

EAP-Message Direct 5

This protocol is vulnerable to cyber threats due to its one-way transmission. It doesn’t provide per-session WEP keys but is compatible with old endpoints legacy networks.


Security is a vital aspect of technology, considering how the public network framework is changing. Having a secure EAP will help to protect your device from cyber-attacks.

As you can see, the best EAP methods vary depending on the type of network and the user’s requirements. Telecommunication is evolving. 5G is fast developing. It is essential to know the right method for your organization.

The development of 5G is a critical subject to take note of. There is an increase in cyber attacks. It is essential to implement the right EAP for your organization.
