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.
Aylsham (/ˈeɪlʃəm/ or /ˈeɪlsəm/) is a historic market town and civil parish on the River Bure in north Norfolk, England, nearly 9 mi (14 km) north of Norwich. The river rises near Melton Constable, 11 miles (18 km) upstream from Aylsham and continues to Great Yarmouth and the North Sea, although it was only made navigable after 1779, allowing grain, coal and timber to be brought up river.
The town is close to large estates and grand country houses at Blickling, Felbrigg, Mannington and Wolterton, which are important tourist attractions.
The civil parish has an area of 4,329 acres (17.52 km2) and in the 2001 census had a population of 5,504 increasing to a population of 6,016 at the 2011 census. For the purposes of local government, the parish falls within the district of Broadland.
