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.
South East England is one of the nine official regions of England at the first level of ITL for statistical purposes. It consists of the counties of Buckinghamshire, East Sussex, Hampshire, the Isle of Wight, Kent, Oxfordshire, Berkshire, Surrey and West Sussex. Major towns and cities in the regions include Brighton and Hove, Milton Keynes, Southampton, Portsmouth, Slough, Reading and Oxford.
South East England is the third largest region of England, with an area of 19,096 km2 (7,373 sq mi), and is also the most populous with a total population of over eight and a half million (2011). The region contains seven legally chartered cities: Brighton and Hove, Canterbury, Chichester, Oxford, Portsmouth, Southampton and Winchester. The region's close proximity to London and connections to several national motorways have led to South East England becoming a prosperous economic hub with the largest economy of any region in the UK, after London. The region is home to Gatwick Airport, the UK's second-busiest airport, and Heathrow Airport (the UK's busiest airport) is located adjacent to the region's boundary with Greater London. The coastline along the English Channel provides numerous ferry crossings to mainland Europe.
The region is known for its countryside, which includes two national parks: the New Forest and the South Downs, as well as the North Downs, the Chiltern Hills and part of the Cotswolds. The River Thames flows through the region and its basin is known as the Thames Valley. It is also the location of a number of internationally known places of interest, such as HMS Victory in Portsmouth, Cliveden in Buckinghamshire, Thorpe Park and RHS Wisley in Surrey, Blenheim Palace in Oxfordshire, Windsor Castle in Berkshire, Leeds Castle, the White Cliffs of Dover and Canterbury Cathedral in Kent, Brighton Palace Pier, and Hammerwood Park in East Sussex, and Wakehurst Place in West Sussex. The region has many universities; the University of Oxford is the oldest in the English-speaking world, and ranked among the best in the world.
South East England is host to various sporting events, including the annual Henley Royal Regatta, Royal Ascot and The Derby, and sporting venues include Wentworth Golf Club and Brands Hatch. Some of the events of the 2012 Summer Olympics were held in the south east, including the rowing at Eton Dorney and part of the cycling road race in the Surrey Hills.
In medieval times, South East England included much of the Kingdom of Wessex, which was the precursor to the modern state of England. Winchester was the capital of England after unification of the various states, including the kingdoms of Kent, Sussex and Mercia. Winchester stopped being the administrative capital of England some time in the 13th century as its influence waned while the City of London dominated commerce. The last monarch to be crowned at Winchester was Richard II in 1377, although the last monarch to be crowned by the Bishop of Winchester was Queen Mary I in 1553.
