| Protocol | Description |
|---|---|
| EAP | Allows for arbitrary authentication of a remote access connection through the use of authentication schemes, known as EAP types. |
What are the different types of remote access authentication?
Remote access authentication options. Remote access servers can be configured as dial-in servers or VPN servers. Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol.
What is a remote authentication protocol?
The acronym is actually fairly descriptive of what it does: The worker will remotely authenticate for access to that remote network. I have previously mentioned that I like to map protocols before to the OSI Reference Model. This helps one visualize just what protocols belong where in the grand scheme of things.

Which protocol is used for centralized authentication and authorization with remote access?
Which of the following are methods for providing centralized authentication, authorization, and accounting for remote access? (Select two.) Both RADIUS and TACACS+ are protocols used for centralized authentication, authorization, and accounting with remote access.
What is the best remote access authentication?
Extensible Authentication Protocol-Transport Level Security is the most secure remote authentication protocol. It uses certificates on both the client and the server to provide mutual authentication, data integrity, and data confidentiality.
Which protocol should you configure on a remote access server to authenticate remote users with smart cards?
EAP-TLS is the only authentication method supported when smart cards are used for remote authentication.
Which 2 methods of authentication can be used for remote access connections?
remote access servers support the following set of authentication methods:Password. Authentication Protocol (PAP)Challenge. Handshake Authentication Protocol (CHAP)Microsoft's. implementation of CHAP (MS-CHAP)Updated. version of MS-CHAP (MS-CHAP2)Extensible. Authentication Protocol/Transport Layer Security (EAP/TLS)
Which EAP implementation is most secure?
EAP-TLS. This is the most secure method as it requires certificates from client and server end. The process involves mutual authentication where client validates server certificate and server validates client certificate.
What is the difference between PEAP and EAP-TLS?
Eap-tls is based on client certificate authentication while peap-eap-tls is based on server side certificate authentication. With peap-eap-tls, the 1st phase will be the encrypted tunnel with server side authentication and then all user sensitive information are encrypted.
What is CHAP protocol used for?
CHAP (Challenge-Handshake Authentication Protocol) is a challenge and response authentication method that Point-to-Point Protocol (PPP) servers use to verify the identity of a remote user.
What are the 3 methods of authentication?
Authentication factors can be classified into three groups: something you know: a password or personal identification number (PIN); something you have: a token, such as bank card; something you are: biometrics, such as fingerprints and voice recognition.
What are the types of authentication methods?
5 Common Authentication TypesPassword-based authentication. Passwords are the most common methods of authentication. ... Multi-factor authentication. ... Certificate-based authentication. ... Biometric authentication. ... Token-based authentication.
How many types of authentication protocols are there?
EAP - Extensible Authentication Protocol More than 40 EAP-methods exist, the most common are: EAP-MD5. EAP-TLS. EAP-TTLS.
What is EAP authentication method?
Extensible Authentication Protocol (EAP) is an authentication framework, not a specific authentication mechanism, frequently used in wireless networks and point-to-point connections. It provides some common functions and negotiation of authentication methods called EAP methods.
Which authentication method is commonly used for more secure wireless networks?
WPA stands for WiFi Protected Access. This authentication method uses different encryption algorithms to encrypt the transport. Therefore, this type of network cannot be forged easily, unlike open networks, and users get privacy. Today, WPA2 is probably the most commonly used method to secure WiFi networks.
What is EAP method TLS?
EAP-TLS (Transport Layer Security) EAP-TLS provides certificate-based, mutual authentication of the network and the client. Both the client and the server must have certificates to perform this authentication. EAP-TLS randomly generates session-based, user-based Wired Equivalent Privacy (WEP) keys.
How do I authenticate remote users?
In the management GUI, select Settings > Security > Remote Authentication. Select Configure Remote Authentication. Select LDAP. Select the type of LDAP server that is used for authentication.
Which of the following is the most common form of authentication?
Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters.
What is the purpose of remote user authentication?
Remote user authentication is a mechanism in which the remote server verifies the legitimacy of a user over an insecure communication channel.
What type of password is Maryhadalittlelamb?
What type of password is maryhadalittlelamb? Explanation: A pass phrase is a password based on a phrase, such as maryhadalittlelamb. Cognitive passwords are passwords that relate to things that people know, such as a mother's maiden name, or the name of a pet.
What is remote access server?
Remote access servers can be configured as dial-in servers or VPN servers. Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. Windows remote access servers support the following set of authentication methods: 1 Password Authentication Protocol (PAP) 2 Challenge Handshake Authentication Protocol (CHAP) 3 Microsoft's implementation of CHAP (MS-CHAP) 4 Updated version of MS-CHAP (MS-CHAP2) 5 Extensible Authentication Protocol/Transport Layer Security (EAP/TLS)
Why is PAP not used?
The only reason to use PAP is if the remote access client and remote access server are not able to negotiate a more secure authentication method.
What is EAP TLS?
EAP/TLS provides for use of more secure authentication methods such as smart cards, Kerberos, and digital certificates, which are much more secure than the user name/password authentication methods above. It's defined in RFC 2716.
Why is it important to verify identity?
The ability to verify identity (authentication) is even more important for remote users than for those who are on-site, since without a secure authentication scheme anyone could get into the network and view, copy, change or even destroy important data. The choices you make have implications for ease of administration and security as your network ...
What is the protocol used for dial in VPN?
Dial-in servers use the Point-to-Point Protocol (PPP) or in the case of some older servers, the Serial Line Internet Protocol (SLIP) as the link layer protocol. VPN servers can use the Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), or IPSec tunnel mode to establish a secure "tunnel" over the Internet. ...
