What is Access Control in Network?

The need for network security is a relatively new requirement. Security incidents are rising at an alarming rate every year. As the complexity of the threats increases, so do the security measures required to protect networks. Information Systems are decomposed in three main portions, hardware, software and communications with the purpose to identify and apply information security industry standards, as mechanisms of protection and prevention, at three levels or layers: Physical, personal and organizational. Overview of Access Control Access control is generally a policy or procedure that allows, denies or restricts access to a system. It may, as well, monitor and record all attempts made to access a system. Access Control may also identify users attempting to access a system unauthorized. It is a mechanism which is very much important for protection in computer security. Access control approaches determine how users interact with data and other network resources. Furthermore, access control measures ensure data are protected from unauthorized disclosure or modification. Access control is the traditional center of gravity of computer security. It is where security engineering meets computer science. Its function is to control which principals have access to which resources in the system—which files they can read, which…
