Exploring the Benefits of Cloud 802.1X Security for Modern Enterprises

In modern times, cloud infrastructure is expeditiously superseding on-premise infrastructure as the favoured alternative for numerous enterprises. The myriad benefits of cloud computing are especially evident in the realm of cybersecurity. Due to the escalating need for safeguarded wireless networks, 802.1X authentication has surfaced as the predominant standard for guaranteeing network security.

The protocol was formerly established via on-premises infrastructure. Nevertheless, cloud-based solutions such as Azure AD and SecureW2’s Cloud RADIUS are increasingly prevalent. In this article, we shall delve into the advantages of leveraging cloud infrastructure for 802.1X authentication, while also highlighting the disparities between on-premise and cloud-based environments.

Understanding the Basics of 802.1X and WPA2 Enterprise

The 802.1X protocol is a highly effective network authentication mechanism that is widely employed to guarantee secure network access. IEEE has developed a port-based network access control protocol that is widely accepted as a standard in the cybersecurity industry. The protocol operates through the process of device authentication for network-connected endpoints, including laptops and smartphones, to ensure that solely authorised users are granted access to the network.

The implementation of 802.1X allows for individualized user authentication through the utilization of either password or digital certificate credentials, thereby enabling network access. Digital certificates serve as virtual identification badges that enable secure authentication and access. Certificates are issued by Certificate Authorities (CAs) to clients and comprise of crucial information that is utilized for user or device identification purposes.

WPA2-Enterprise is a security protocol that utilises 802.1X authentication for enhanced security measures. In contrast to the widely used WPA2-PSK protocol, the WPA protocol provides a greater array of security measures for Wi-Fi protection. It is imperative that every user provides a unique username and password for network access when utilising WPA2-Enterprise, which facilitates personalised user authentication. In contrast to the utilisation of WPA2-PSK, where all users are mandated to share a common password.

The utilization of 802.1X and WPA2-Enterprise is interdependent. The nomenclature is frequently utilized interchangeably, consequently. Establishing a WPA2-Enterprise network with unique user credentials fortifies the network’s security posture by mitigating the risk of unauthorized access from malicious actors. The absence of a shared password eliminates the possibility of password theft, thereby enhancing the network’s resilience against cyber threats.

The Components of 802.1X and WPA2 Enterprise

Three basic components make up the 802.1X authentication framework: the supplicant, the authenticator, and the authentication server. In the realm of network security, the term “supplicant” refers to the client device, like a cell phone or computer, that is endeavoring to establish a network connection. The wireless access point, commonly referred to as the network access device, functions as the authenticator within the system. The established entity responsible for handling authentication is the authentication server, which may take the form of a RADIUS server.

The tripartite components employed in 802.1X authentication are similarly leveraged in WPA2 Enterprise. Utilizing distinct credentials for each user provides an extra level of protection. It is imperative to authenticate user credentials against the authentication server prior to granting network access.

Why Is 802.1X the Best Solution for Enterprise Network Security?

In the realm of enterprise network security, 802.1X is widely acknowledged as the most robust and impregnable option available. The robust access control and authentication mechanisms in place ensure that network access is restricted to authorised personnel and devices, thereby enhancing security. In addition, the implementation of 802.1X provides enterprises with the flexibility to safeguard their network through the utilisation of diverse authentication techniques, including but not limited to username/password, digital certificates, and smart cards.

In contrast to other network security protocols, WPA2-PSK networks employ a uniform password for all users, thereby rendering them susceptible to password breaches or unauthorized dissemination. The aforementioned action could potentially lead to illicit network entry and plausible data security violations. It is imperative to note that WPA2-Enterprise surpasses WPA2-PSK in terms of security as it provides personalized user authentication and utilizes 802.1X for authentication.

On-Premise 802.1X Security

Formerly, the 802.1X security protocol was implemented to verify user identities through local infrastructure, such as Active Directory and NPS (RADIUS Server). The traditional approach does possess certain significant constraints, however.

A notable drawback associated with on-premise infrastructure pertains to the substantial expenses incurred during the setup and maintenance phases. In order to effectively oversee the infrastructure, it is imperative for businesses to allocate resources towards requisite technology, software, and personnel. Scaling the infrastructure to accommodate the organization’s growing demands could pose significant challenges and incur substantial costs.

The scalability of on-premise infrastructure is comparatively inferior to that of cloud-based alternatives. The process of incorporating additional locations or users requires meticulous manual configuration, which can be a laborious and vulnerable task. Additionally, it could potentially pose challenges for an organization to expeditiously adapt to novel circumstances and requisites.

In essence, while on-premise infrastructure may offer a degree of security, it presents a costly and challenging-to-expand alternative, rendering it less appropriate for modern enterprise networks.

The Advantages of Cloud 802.1X Security for Enterprise Networks

Cloud-based 802.1X security offers organizations a handful of major advantages. Those advantages include the following:
