What is the difference between authentication and authorization?

Authentication verifies the identity of a user or service, and authorization determines their access rights. Although the two terms sound alike, they play separate but equally essential roles in securing applications and data. Understanding the difference is crucial. Combined, they determine the security of a system.

What EAP method should I use?

Does BIG IP use group based accounts?

Important: If you configure access control settings for group-based accounts (using the remote role groups feature), the BIG-IP system always applies those settings, rather than the default access control settings, to group-based accounts .

Does BIG IP apply to group based authorization?

Important: The values you specify in this procedure for the Role, Partition Access, and Terminal Access settings do not apply to group-based authorization. These values represent the default values or locally configured user accounts (which override the default role) that the BIG-IP system applies to any user account that is not part of a remote role group.

Can you authenticate BIG IP?

You can now authenticate administrative traffic for BIG-IP system user accounts that are stored on a remote RADIUS server. If you have no need to configure access control for remotely-stored user groups, your configuration tasks are complete.

What is the most secure remote authentication protocol?

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. It negotiates encryption algorithms and secures the exchange of session keys. Use EAP-TLS if you implement multifactor authentication technologies, such as smart cards or universal serial bus (USB) token devices.

What does "enabled" mean in server authentication?

This item specifies that the client verifies that server certificates presented to the client computer have the correct signatures, have not expired, and were issued by a trusted root certification authority (CA). The default setting is "enabled." If you disable this check box, client computers cannot verify the identity of your servers during the authentication process. If server authentication does not occur, users are exposed to severe security risks, including the possibility that users might unknowingly connect to a rogue network.

How to specify a server name in a RADIUS certificate?

Note that you must type the name exactly as it appears in the Subject field of each RADIUS server certificate, or use regular expressions to specify the server name. The complete syntax of the regular expression can be used to specify the server name. But to differentiate a regular expression with the literal string, you must use at least one * in the string specified. For example, you can specify nps*.example.com to specify the RADIUS server nps1.example.com or nps2.example.com. Even if no RADIUS servers are specified, the client will verify that the RADIUS server certificate was issued by a trusted root CA.

What is a remote authentication dial in user service?

The remote authentication dial in user service (RADIUS) protocol is a third-party authentication system. RADIUS is described in RFCs 2865 and 2866, and it uses the UDP ports 1812 (authentication) and 1813 (accounting). RADIUS formerly used the unofficially assigned ports of 1645 and 1646 for the same respective purposes, and some implementations continue to use those ports.

How does trust pass authentication requests?

How a specific trust passes authentication requests depends on how it is configured; trust relationships can be one way, providing access from the trusted domain to resources in the trusting domain, or two way, providing access from each domain to resources in the other domain . Trusts are also either nontransitive, in which case trust exists only between the two trust partner domains, or transitive, in which case trust automatically extends to any other domains that either of the partners trusts.

What is a dial in user service?

Remote Authentication Dial-In User Service (RADIUS) is a protocol that originally was created for dial-in authentication and authorization service. Now, its role has expanded to include wireless access point access, authenticating Ethernet switches, virtual private network servers, and more. In Windows Server 2008, the RADIUS function is now handled by the Network Policy and Access Services role.

What is authentication in NAS?

Authentication The server seeking access sends a request to NAS. The NAS then creates and sends a RADIUS Access Request to the RADIUS Server. This request acts as an authorization to grant access. Typically, a user name and password or some other means of establishing identity is requested for this process, which must then be provided by the user seeking access. The request will also contain other means of verification that the NAS collected, such as physical location of the user and/or the phone number or network address of the user.

What is a PAP server?

The Password Authentication Protocol (PAP) is defined by RFC 1334 ( http://tools.ietf.org/html/rfc1334#section-2) and is referred to as being, “not a strong authentication method.” [17] A user enters a password and it is sent across the network in clear text. When received by the PAP server, it is authenticated and validated. Sniffing the network may disclose the plaintext passwords. Sniffing refers to monitoring network communications and capturing the raw TCP/IP traffic.
