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]

​Rickmansworth (/ˈrɪkmənzwərθ/) is a town in southwest Hertfordshire, England, about 17 miles (27 km) northwest of central London and inside the perimeter of the M25 motorway. The town is mainly to the north of the Grand Union Canal (formerly the Grand Junction Canal) and the River Colne. The town of Watford is 5 miles (8 km) to the northeast. Rickmansworth is the administrative seat of the Three Rivers District Council. The confluence of the River Chess and the River Gade with the Colne in Rickmansworth inspired the district's name. The enlarged Colne flows south to form a major tributary of the River Thames. The town is served by the Metropolitan line of the London Underground and Chiltern Railways from London Marylebone to Aylesbury railway station.
