In physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.
However, in recent years, access control has extended to digital platforms. Because of this, the protection of external databases to preserve digital security is more important than ever.
Scholars have considered access control to be a very significant aspect of privacy that should be further studied. Access control policy determines what an organization’s security policy will be. In order to verify the access control policy, organizations use an access control model, but the model does not include details on how the security policy is put into place. Having and building a suitable access control model is therefore essential.
March is a Fenland market town and civil parish in the Isle of Ely area of Cambridgeshire, England. It was the county town of the Isle of Ely which was a separate administrative county from 1889 to 1965. It is now the administrative centre of Fenland District Council.
The town grew by becoming an important railway centre. Like many Fenland towns, March was once an island surrounded by marshes. It occupied the second largest "island" in the Great Level. As the land drained, the town grew and prospered as a trading and religious centre. It was also a minor port before, in more recent times, a market town and an administrative and railway centre. March is situated on the banks of the navigable old course of the River Nene, today mainly used by pleasure boats.
