Can you have multiple remote access servers on Windows 2003?
Windows 2003 Server Enterprise Edition's IAS implementation puts no limits on the number of RADIUS clients you can configure or on the number of RADIUS server groups you can have. Even more importantly, a single RADIUS server can support many remote access servers, so that as you add additional dial-in and/or VPN servers, their users are all still authenticated through one central point: the RADIUS server. The fact that the authentication server is separate from the access server (s) makes this both more secure and more scalable than other authentication methods.

Kerberos uses DES encryption to authenticate a user when logging in to the system.
What is remote access authentication protocol?
A remote access authentication protocol is the method by which remote users will be authenticated when they log on the network. One (unwise) choice is to allow users to log on without authentication.
What is EAP authentication?
EAP allows for authentication of a remote access connection through the use of authentication schemes, known as EAP types. EAP offers the strongest security by providing the most flexibility in authentication variations. EAP can support authentication mechanisms, such as token cards, smart cards, certificates, and public key encryption authentication.
What is secure authentication?
Secure authentication (i.e., for higher levels of assurance) requires a multi-factor approach. In general, the combination of authentication factors should include some or all of the three above categories.
When identity data shared by the ID system and stored by the relying party as part of the authentication mechanism, what?
When identity data shared by the ID system and stored by the relying party as part of the authentication mechanism, ensure that information is secured in order to prevent loss or compromise.
What is federation in identity?
Federation is the ability of one organization to accept another organization’s identity credentials for authentication based on inter-organizational trust. The trusting organization must be comfortable that the other identity provider has acceptable policies, and that those policies are being followed. Federation protocols and assurance and trust frameworks facilitate federation of digital identity between organizations. For federation to be effectively used globally, agreement and mapping with the ISO defined assurance framework and the adoption of standards are critical (Source: Catalog of Technical Standards ).
Why is online authentication important?
Ultimately, online authentication provides a higher level of assurance because it offers more potential authentication factors and a “live” source. At the same time, it may also bring greater data protection and cybersecurity risks.
What is the purpose of establishing a secure communication channel between the relying parting (service provider) and?
Establish a secure communication channel between the relying parting (service provider) and the identity provider to enable an authentication workflow between the service provider and identity provider application. This is typically done using digital certificates to secure communication and may also involve passwords (a shared secret) to authenticate the application.
What is the level of assurance provided by online mechanisms?
The authentication level of assurance provided by online mechanisms varies according to the specific credentials, authenticators, and protocols used. In addition to choosing authentication methods with levels of assurance appropriate to the transaction, practitioners must consider their accessibility and convenience, particularly for vulnerable persons (e.g., low literacy, the elderly, and people with disabilities), and those with unreliable internet or mobile connections. For example, card-based authentication for remote transactions (e.g., e-services) would require the purchase and distribution of card and/or biometric readers to each person, which may be a barrier to adoption.
What is manual verification of ID?
Manual (non-digital) comparison (i.e., taking an ID card at face value): Traditionally, authentication processes have involved the manual inspection of credentials (commonly ID cards) to determine that they are genuine ( e.g., via embedded security features) and assess whether the person or their physical signature resembles the photo or signature included on the credential. While this method is intuitive and requires less infrastructure (beyond providing the credentials themselves), it provides a lower level of assurance and more opportunities for corruption than digital authentication due to the potential for human error and/or discretion in applying the procedure. At the same time, this may be appropriate for certain low-risk transactions and/or the only viable solution in areas with no connectivity or electricity. If security features are to be a viable method of improving the reliability of authentication, relying parties need to be aware and appropriately equipped—e.g., I the case of level 2 (covert) security features, this might require a UV light.
How does secure remote access work?
