AAA/Radius Servers

Explore the critical role of RADIUS servers in enterprise-level network security, learn about on-premise vs. cloud-based servers, and discover the key factors to consider when choosing a Cloud RADIUS server.

RAY Solutions provides the latest solutions in providing Authentication, Authorization, and Accounting (AAA) solutions to address today’s growing, complex and scaled networks which serves the rapidly growing sub-scriber base.

Secure networks are essential in today's digital world, especially for large-scale enterprises dealing with extensive networks. An effective solution is RADIUS (Remote Authentication Dial-In User Service) servers, renowned for AAA (authentication, authorization, and accounting) functionalities. They ensure robust Wi-Fi, VPN, and wired security by authenticating each connection, granting variable user access levels, and recording connection logs.

A Must for Enterprises

The digital world's evolving nature consistently presents new cybersecurity threats. The bigger the network, the more potential attack points. Enterprise networks relying on PSKs (pre-shared keys) often face multiple cyber threats, including:

  • Over-the-air and Man-in-the-middle attacks
  • Brute force and dictionary attacks
  • Phishing attacks

Moreover, human factors are significant risk contributors, with a majority of users reusing passwords. This habit compromises even the most secure password systems, endangering your Wi-Fi and VPN security. RADIUS servers for enterprises fortify security by assigning individual credentials to each user, eliminating shared password vulnerabilities. The use of digital certificates further enhances this security by eliminating password-related risks.

On-Premise vs. Cloud RADIUS Servers

Historically, enterprises used on-premise RADIUS servers for stringent compliance and data security audit requirements. However, drawbacks like high replication costs for every location and extended deployment times have led to the rise of cloud-based RADIUS servers. These servers offer scalability and quick deployment, with expert engineer support making solutions like Cloud RADIUS increasingly popular.

Choosing Your Cloud RADIUS Server

The vast array of cloud RADIUS services can be overwhelming for network administrators. While deciding, consider these critical factors:

  • Integration & Deployment Ease: The ideal RADIUS server should seamlessly integrate with your existing infrastructure, avoiding extensive changes that can prolong vulnerability periods. Check the RADIUS's compatibility with your Identity Providers and Wi-Fi vendors.
  • Authentication Method Compatibility: Most RADIUS servers support credential-based authentication. However, digital certificates offer superior security and ease of deployment with a well-managed PKI service. Ensure that your chosen RADIUS server supports your preferred authentication type, be it certificates or passwords.
  • Support & Documentation: Comprehensive support and documentation ensure smooth setup and troubleshooting.
  • Regular Updates: Regular updates help to stay ahead of emerging threats.

Overall, selecting a cloud RADIUS server requires thoughtful consideration of your enterprise's specific needs and existing infrastructure.
