EAP-FAST as proclaimed by Cisco marketing would be “as secure as PEAP” and “as easy as LEAP”! EAP-FAST achieves this by creating the same secure encrypted tunnel used to protect user credentials during the authentication session as PEAP without the need for any kind of PKI on the client end or even the server end.
What is the main advantage of EAP-fast over EAP TLS and PEAP?
FAST was created by Cisco Systems as an alternative to PEAP that allows for faster re-authentications and supports faster wireless roaming. Just like PEAP, FAST forms a TLS outer-tunnel and then transmits the client credentials within that TLS tunnel.
What does the fast in EAP-FAST stand for?
EAP-FAST, also known as Flexible Authentication via Secure Tunneling, is an EAP (Extensible Authentication Protocol) developed by Cisco. Its purpose is to replace the LEAP (lightweight extensible authentication protocol).
What does EAP-FAST use for mutual authentication?
EAP-FAST uses a tunnel to provide mutual authentication like PEAP and EAP-TTLS. EAP-FAST does not have the server authenticate itself with a digital certificate. Instead, it uses a Protected Access Credential, which creates a one-time provisioning exchange with a shared secret, or PAC key.
Is EAP MD5 secure?
EAP-based authentication procedure flow * EAP-MD5: EAP-MD5 is the base security requirement in the EAP standard and uses username and passwords as the authentication credentials. EAP-TLS provides mutual authentication between the client and the authentication server and is very secure.
What is the primary benefit of using EAP-TLS for authentication?
EAP methods protect a specific portal so that only users with an authentication key or password can get network access. These methods limit the number of users and help prevent network congestion, making networks faster and more secure.
How does EAP-FAST WORK?
EAP-FAST authenticates by means of a PAC (Protected Access Credential) which can be managed dynamically by the authentication server. The PAC can be provisioned (distributed one time) to the client either manually or automatically.
What is Microsoft Protected EAP?
The Extensible Authentication Protocol (EAP) is an architectural framework that provides extensibility for authentication methods for commonly used protected network access technologies, such as IEEE 802.1X-based wireless access, IEEE 802.1X-based wired access, and Point-to-Point Protocol (PPP) connections such as …
What are two reasons why WEP is considered unreliable?
WEP has been widely criticized for a number of weaknesses.
- Weakness: Key Management and Key Size.
- Weakness: The Initialization Vector (IV) is Too Small.
- Weakness: The Integrity Check Value (ICV) algorithm is not appropriate.
- Weakness: WEP’s use of RC4 is weak.
- Weakness: Authentication Messages can be easily forged.
What are the phases of the EAP-FAST protocol?
EAP-FAST has three phases. Phase 0 is an optional phase. In Phase 1 the client and the AAA server uses the PAC to establish TLS tunnel. In Phase 2, the client sends user information across the tunnel.
Is EAP a security issue?
SECURITY ISSUES As mentioned before, EAP is a standard that provides an infrastructure for network access clients and authentication servers. EAP does not specify the authentication mechanism itself but the way it is negotiated by the communicating parties. Consequently, EAP has no security issues in itself.
What is the difference between leap and EAP FAST?
EAP-FAST (Flexible Authentication via Secure Tunneling) is a method designed by Cisco Systems to fix the weaknesses of LEAP. Use of server certificates is optional in EAP-FAST. EAP-FAST uses a Protected Access Credential (PAC).
What is the PAC used for in EAP FAST?
The PAC is used to establish a tunnel that is then used to perform authentication. The three-phase EAP-FAST protocol is shown in Table 7-3. This phase is independent of other phases; hence, any other scheme (in-band or out-of-band) can be used in the future.
