The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Advice on setting up port-based/wireless security

Asked by scampgb in Miscellaneous Networking, Network Switches & Hubs, IPSec Security Protocol

Hi

Unfortunately I don't think there's a 'correct' answer for this one, but I'm after some advice as to what I need to look into and do.

Here's the scenario:
I have a star-topology network, with a few dozen small sites connected into a hub site.
The WAN network is supplied and managed by a third-party.
The remote sites only have a handful of users each, connected to either a simple hub or unmanaged switch

I also have a fair number of roving users with laptops.

I'm concerned that it's possible for someone to plug a "rogue" machine into the network.  Although the sites are physically secure, it's still a concern of mine.  I'd also like to introduce wireless networking for laptop users - to make life a little bit simpler.

What I want to achieve:
A system of MAC-address based security that can be centrally controlled to allow machines to connect to the network, irrespective of location or whether they're using fixed cabling or wireless.
Unsurprisingly I don't want to spend huge amounts of money, and I'm looking for a solution that I can roll out gradually.


Any suggestions?
