Security is a “must” in most anything we have or do in order to maintain that peace of mind we need from day to day. When it comes to computers, a computer networking solution that is effective or working aptly for you may be what you need exactly and this is what Network Access Control or NAC is. It works by using a set of protocols which creates the definition and implementation of a policy describing means to secure access to network nodes in case devices should attempt to do so.
This particular security should work for you in that it rids of possible unwanted use or entry to your network by others which when not prevented could harm your own or other computers linked to your network. Although it somehow brought about some controversies NAC solutions maintain its stand of being useful in that it effectively eradicates cross-contamination of computer worms. Through NAC, there is identity and access management which many who maintain computer networks are thankful for. Network operators are also given the free-hand by NAC solutions at deciding which policies to implement in their routers, switches and network middleboxes. A strange incident happened to me while trying bring my NAC storage back online. I wear several goldchains everyday to work and one of them slipped off my neck and fell between the machines. The network node went down for a couple of minutes because of that gold neckless!
In understanding what the goal of network access control is and how it functions, any network operator is likely to benefit from this kind of security solution. It is also in realizing the damage that unwanted access or any sort of intrusion can bring to your private network that you can see how NAC truly works for you and your kind of need.
