RADIUS Insecurity RADIUS is almost thirty years old, and uses cryptography based on MD5. Given that MD5 has been broken for over a decade, what are the implications for RADIUS? Why is RADIUS still using MD5? RADIUS sti... Network Security Protocols
Announcing SRADIUS RADIUS has used MD5 for security for almost thirty years. It is time to use a modern alternative: SRADIUS! We just released an Internet-Draft which defines “Secure RADIUS”, or “SRADIUS”. We also have ... Network Security Protocols
Introducing RADIUS 1.1 RADIUS has a problem. The name of the problem is MD5. The MD5 hash algorithm was defined in 1991, and was used in RADIUS in 1993. However, MD5 is no longer secure. It is a bit of a miracle that RADIUS... Network Security Best Practices Network Security Protocols
Looking Forward to IETF 122 We have been involved in the Internet Engineering Task Force (IETF) for a few decades now. During that time, we have written many of the RADIUS standards. We are still involved in the standards proces... Network Security Protocols

Making RADIUS More Secure As we’ve previously discussed, there are several insecure elements in RADIUS. We are currently working in the IETF (Internet Engineering Task Force) to close those gaps and improve security for everyo... Network Security Protocols
How to customize an OEM instance of FreeRADIUS As the most popular RADIUS server in the world, FreeRADIUS is used by many hardware vendors. They ship their products with FreeRADIUS as an embedded or “OEM” product. It is common for them to need som... Network Security Protocols
RADIUS protocol and password compatibility In order for RADIUS authentication to work, user passwords need to be stored in a format that is understood by the authentication protocol used by the client. Unfortunately, not all protocols work wit... Network Security Best Practices Network Security Protocols
PAP vs CHAP. Is PAP less secure? One of the most common questions about RADIUS security asks “Is PAP secure?” The usual answer is “no”, which is (in our opinion) seriously misleading. A better answer is “Here’s a comparison of PAP an... Network Security Best Practices Network Security Protocols
