Network Access Control: Securing Confidential Info

Network Access Control (NAC) is a word used by many IT groups, as it is connected to computer network security. NAC limits access to the computers, networks, and systems of a particular group. In this manner, computers, networks, and systems are restricted from unauthorized personnel, devices, and programs (especially malicious software). By enforcing network security, company data and systems are protected, and confidential information is safeguarded.

Without NAC, the integrity of entire companies and organizations, as well as their affiliates, would be jeopardized. Sometimes, employees will use passwords that are not very secure. Insecure passwords are used because it can be difficult to remember passwords that are too long or have unusual combinations of special characters, numbers, and letters in both upper and lower cases. Forgetting a password can be a hassle, as it will bar access to devices, programs, and entire networks. This in turn, can compromise productivity, and impede the workflow of companies and organizations.

Passwords that can be easily identified by unauthorized third party programs and personnel carries a much bigger risk. With Network Access Control, these risks are minimized or obliterated. IT personnel who are in charge of password creation and resets, and managing any restricted information, will embed sophisticated passwords into every employee's swipe card.
