The Internet Authentication Service (IAS) on Windows® ensures secure network use by enabling authentication, authorization, and accounting (AAA). AAA prevents unauthorized access, assigns user privileges, and tracks network usage for better budgeting.
The Internet Authentication Service (IAS) on Windows® operating systems enables integrated authorization, authentication, and accounting for networks. Ensures that the network remains secure while monitoring the use of network resources within the organization. The end result of this is an integrated process that keeps each specific system user in place while protecting the system from external threats and checking that network resources are being used correctly.
The Internet Authentication Service works by enabling built-in authentication, authorization and accounting (AAA) on a Windows® operating system. AAA is a typical information security principle that prevents unauthorized users from accessing a system. It ensures that each user stays within their specific permission base and tracks all occurrences on the network to help an organization plan its time, spending and resources.
The authentication portion of the Internet Authentication Service ensures that any user attempting to access the network is actually authorized to use the system. Think of it like a guest list for a party: without a valid invite, a user cannot access the system. By constantly monitoring the people working to access the network, the Internet Authentication Service works to keep hackers out without compromising functionality for legitimate users.
Authorization keeps each user of the system within their own privilege level. From basic users to system administrators, each user on the network is assigned a list of privileges that determine what actions they can take on the system. Authorization verifies a user’s actions against permitted actions, preventing individuals from abusing the system once logged in. For example, basic users of a system typically cannot install or remove programs on their computer; if a basic user attempted to do this, the authorization component of the Internet authentication system would prevent the action.
Finally, accounting serves to maintain a constant measure of network resources used by individuals accessing the system. This allows an organization to evaluate network usage over time, more closely matching its actual expenditures to planned expenditures. A more effective budget for network resources can help businesses see where and how they can save money in the long run, providing them with the ability to save energy, hardware, and bandwidth costs on their network.
