Network Access Control (NAC) is a computer network security tool that tries to implement endpoint security technology, user or system against fraudulent transmissions and network security enforcement.
Network Access Control (NAC) by means of a set of protocols defines and implements a policy that describes how to secure access to network when attempt is made to access it. On of the definitions Paul Rubens gives who is a frequent contributor to Internet.com and writes regularly for ServerWatch.com, EnterpriseStorageForum.com and EnterpriseNetworkingPlanet.com to NAC is as follows: “Network Access Control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do”.
There are several basic terms that make it easier the core understanding of Network Access Control:
1. Security policy
A security policy is a document that determines and represents the rules, laws and practices for computer network access. A security policy is a document that outlines the rules, laws and practices for computer network access. This document regulates how an organization manage its sensitive information..
2. Network management
This is the management of computer networks. There exists a wide range of software and hardware products that help network system administrators to manage a network. Network management covers a wide area, including:
3. Security: Ensuring that the network is protected from unauthorized intruders.
4. Performance: Eliminating obstacles hindering network activities.
5. Reliability: Making sure the network is available to users and is able to face software malfunctions.
6. Network Admission Control
Abbreviated as NAC, Cisco's Network Admission Control is a set of technologies and solutions that use the network infrastructure to enforce security policy compliance on all devices seeking to access network computing resources.
7. Network Access Protection
Abbreviated as NAP, Microsoft's Network Access Protection is a policy-enforcement platform built into the Microsoft Windows Vista and Windows Server Code Name "Longhorn" operating systems to secure the system from attacks.
Network access control (NAC)
• Prohibits guests from bringing down the network
• The insider threat to the network
• Allows network admins to take immediate countermeasures in cases of necessity on individual devices
• Protects against spyware and malware.
Safe Access is a complete NAC solution that stops unauthorized access, prevents malicious attacks enforcing your organization's security policies.
Safe Access is flexible enough to control all devices and end users.
However when “guests” sometimes try to access secured shares and confidential files. Here comes to help ShareAlarmPro - Network Access Monitoring Software - Advanced All-In-One Network Access Control and Folder Monitoring Software!
ShareAlarmPro is a tool that allows you to see parameters of the workstation which tries to establish a connection with your computer. The remote workstation, user, path, OS, permissions of the accessed folder, connection time will available via this tool. ShareAlarmPro allows easily perform network shares and folder monitoring, block unwanted users attempting to access secured shares and confidential files over network, detect and log accessed files and folders.With ShareAlarmPro you are protected and well-informed about files and folders access over network.

This software also provides you with the ability to manage and monitor all shares on your workstation, disable or enable default administrative shares, hide your workstation on the network, view the number of the users currently connected to each shared resource on your workstation. ShareAlarmPro also lets you easily browse your LAN and view all shared resources irrespective of whether they are hidden or not as well as view connections to shared resources on remote workstations.

The program logs all detected events ( access to shared folders, security events, folder watcher events ) in an HTML format.
If your company is involved in financial services, health care or government work, regulatory requirements make network access control something you should be looking to implement right away. But whatever industry your company works in, security considerations mean that network access control is something you are going to want to implement sooner or later. No matter how long it takes to implement, now is the time to start making plans.
