Question

Your company recently began allowing workers to telecommute from home one or more days a week. However, your company doesn't currently have a remote access solution. They want to implement an AAA solution that supports different vendors. Which is the BEST choice?

Answer 1

The most suitable AAA solutions for a company seeking remote access compatibility with different vendors are RADIUS and TACACS+. RADIUS is more popular for general network access compatibility, while TACACS+ offers more control and encryption for enhanced security.

Step-by-step explanation:

If your company is looking to implement an AAA solution (Authentication, Authorization, and Accounting) that supports different vendors, the best choice would likely be RADIUS (Remote Authentication Dial-In User Service) or TACACS+ (Terminal Access Controller Access-Control System Plus). Both solutions are widely used, provide the AAA framework for access control, and support interoperability with various network vendors. RADIUS is more commonly used and might be preferable for businesses seeking broad compatibility and support. It encrypts only the password during the authentication process and is generally used for network access. TACACS+ provides more granular control over command authorization and encrypts the entire session, which could be a deciding factor if your company requires heightened security. However, exact requirements such as the need for different encryption standards or integration capabilities should guide the final decision.
