Access Control

​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.[1]

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.[2]

​Romford is a large town in east London and the administrative centre of the London Borough of Havering. It is located 14.1 miles (23 kilometres) northeast of Charing Cross and is one of the major metropolitan centres identified in the London Plan.[2] Historically, Romford was a market town in the county of Essex, and formed the administrative centre of the liberty of Havering before that liberty was dissolved in 1892.[3][4] Good road links to London and the opening of the railway station in 1839 were key to the development of the town.[3] The economic history of Romford is characterised by a shift from agriculture to light industry and then to retail and commerce.[3] As part of the suburban growth of London throughout the 20th century, Romford significantly expanded and increased in population, becoming a municipal borough in 1937 and was incorporated into Greater London in 1965.[5][6][7] Today, it is one of the largest commercial, retail, entertainment and leisure districts in London and has a well-developed night-time economy as well.[8][9] Its population, as of 2011, was 122,854.[10]
