Question

A company uses AD and RADIUS To authenticate VPN in Wi-Fi connections. The Chief Information Security Officer initiates a protect to extend a third-party MFA solution to VPN. During the pilot phase, VPN users successfully get an MFA challenge; however, they also get the challenge when connecting to Wi-Fi, which is not desirable. Which of the following best explains why you just are getting the MFA challenge in using Wi-Fi?

1. In the radius server, the proxy rule has not specified the NSA Port type attribute that should be matched

2. in the firewall, the AAA configuration, the IP address of the third-party MFA solution needs to be set as secondary radius server

3. in the third-party MFA solution, authentication properties need to be configured to recognize Wi-Fi authentication request

4. any Wi-Fi configuration, authentication needs to be changed to WPA2 Enterprise using EAP TLS to support the configuration

Answer 1

Dear Student i understand your problem and this question can be answered in a subjective manner.Lets take an example If you want to understand a problem so simply go into deep to acquire more information in order to relate to your query and have a thorough understanding of the topic.Go through the information which I have given below surely you can relate it to your given scenario and have a better understanding.

Radius AUTHENTICATION

Radius (Remote Authentication dial In User Service) is a systems administration convention that gives customer confirmation, approval, and representing the organization. RFC norms 2865 and 2866 portray the RADIUS bookkeeping, individually.

Range convention is executed by various cuts off including Free RADIUS, Steel Belted RADIUS and so forth

A solid verification worker is one that secures applications and other organization assets like Virtual work area Infrastructures and Cisco VPN's and so forth

It upholds different validation techniques like secret key based, once secret key and so on

On the off chance that any RADIUS worker is introduced (to ensure the admittance to an organization) one next to the other to a solid verification worker (to secure the admittance to arrange assets), at that point it is invaluable to coordinate these two workers so the end client can get to the assets he needs by marking on once(Single Sign-on or SSO).

How accomplishes RADIUS Authentication work?

miniOrange can arrange our Authentication item in three potential manners with your RADIUS worker.

One next to the other - Use a current RADIUS worker and design it Side by Side to assign confirmations to your Authentication Server

Masters: Quick Turnaround contrasted with different choices. Utilize existing RADIUS execution Supports PAP, PAP with a Shared Secret, EAP-TLS

CONS: Messy Configuration Heavy impression

Incorporate and Extend - Use a current RADIUS worker and a current extensible component to appoint validations to your Authentication Server

Experts: Better plan than above, underpins PAP, PAP with a Shared Secret, EAP-TLS

CONS: Heavier impression than above

Custom RADIUS - Implement a custom RADIUS usage and agent confirmations to your Authentication Server

Aces: Best Design, Very lightweight Supports PAP, PAP with a Shared Secret, CHAP, MSCHAP, EAP-TLS

CONS: Complex usage

Proposal - Depending on our Business Case, Go with an arranged methodology where we do alternative 1 or 2 for the time being and investigate Option 3. In the mid to long haul, execute Option 3.

​2 Factor Authentication for VPN Login

Diagram

On the off chance that you are utilizing a Virtual Private Network ( VPN ) to permit your clients to associate over a public organization, improving the security turns into a worry since clients access touchy computerized resources. miniOrange can be of incredible incentive here by giving 2-factor Authentication on head of VPN Authentication. This ties down the admittance to secured assets as opposed to depending on just the VPN username/secret key.

What is RADIUS?

Far off Authentication Dial-In User Service (RADIUS) is a customer/worker convention that gives customer validation and approval. It empowers far off access workers to speak with a worker to validate clients and approve their admittance to the mentioned framework or administration.

Span Client

The RADIUS customer is ordinarily a NAS ( Network Access Server ) which is liable for passing client data to assigned RADIUS workers, and afterward dependent on the reaction which is returned, confirms or dismisses login to the client.

Range Server

Range workers are answerable for accepting client association demands, verifying the client, and afterward restoring all design data fundamental for the customer to confirm the client. A RADIUS worker can go about as an intermediary customer to different RADIUS workers or different sorts of verification workers.

Confirmation Protocols

The RADIUS worker watches that the data is right utilizing confirmation plans, for example, PAP, CHAP, MS-CHAP, MS-CHAPv2, EAP, EAP-TLS, EAP-TTLS and EAP-PEAP.

Security

Exchanges between the customer and RADIUS bookkeeping worker are validated using a common mystery, which is never sent over the organization.

Dear student I hope all your queries will be resolved by this explanation and you will surely get some extra help with the description that will resolve your problem with the given toopic.
