London is the capital and largest urban area of England and the United Kingdom. An important settlement for two millennia, London's history goes back to its founding by the Romans. Since its settlement, London has been part of many movements and phenomena throughout history, including the English Renaissance, the Industrial Revolution, and the Gothic Revival. The city's core, the ancient City of London, still retains its limited medieval boundaries; but since at least the 19th century the name "London" has also referred to the whole metropolis that has developed around it. Today the bulk of this conurbation forms the London region of England and the Greater London administrative area, with its own elected mayor and assembly. London is one of the world's leading business, financial and cultural centres, and its influence in politics, education, entertainment, media, fashion and the arts contribute to its status as a major global city. London boasts four World Heritage Sites: The Palace of Westminster, Westminster Abbey and St. Margaret's Church; the Tower of London; the historic settlement of Greenwich; and the Royal Botanic Gardens, Kew. The city is a major tourist destination both for domestic and overseas visitors. London's population draws from a wide range of peoples, cultures, and religions, and over 300 languages are spoken within the city. As of 2006, it had an official population of 7,512,400 within the boundaries of Greater London and is the most populous municipality in the European Union. As of 2001, the Greater London Urban Area had a population of 8,278,251 and the metropolitan area is estimated to have a total population of between 12 and 14 million.

Information Security

Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction.

The terms information security, computer security and information assurance are frequently incorrectly used interchangeably. These fields are interrelated often and share the common goals of protecting the confidentiality, integrity and availability of information; however, there are some subtle differences between them.

These differences lie primarily in the approach to the subject, the methodologies used, and the areas of concentration. Information security is concerned with the confidentiality, integrity and availability of data regardless of the form the data may take: electronic, print, or other forms.

Computer security can focus on ensuring the availability and correct operation of a computer system without concern for the information stored or processed by the computer.

Governments, military, corporations, financial institutions, hospitals, and private businesses amass a great deal of confidential information about their employees, customers, products, research, and financial status. Most of this information is now collected, processed and stored on electronic computers and transmitted across networks to other computers.

Should confidential information about a business' customers or finances or new product line fall into the hands of a competitor, such a breach of security could lead to lost business, law suits or even bankruptcy of the business. Protecting confidential information is a business requirement, and in many cases also an ethical and legal requirement.

For the individual, information security has a significant effect on privacy, which is viewed very differently in different cultures.

The field of information security has grown and evolved significantly in recent years. There are many ways of gaining entry into the field as a career. It offers many areas for specialization including: securing network(s) and allied infrastructure, securing applications and databases, security testing, information systems auditing, business continuity planning and digital forensics science, etc.
