question #2

1.Research 1 company and describe how they protect their company from internet risks.

The Western Union endeavor to maintain physical, electrical and procedural safeguards that comply with applicable government regulations to guard the customer Information. They also endeavor to restrict Information access to their employees, agents and representatives that need to know it. Despite of their efforts, and as you probably know, third parties may unlawfully intercept or access transmissions sent to them or may wrongly instruct you to disclose Information to them while posing as Western Union.


2. Also, research for possible risks or dangers and/or impacts of internet - related crimes to a company.

However, the evolution of the Internet has also created risks for businesses and even entire industries; companies have been caught off-guard as new internet-based business models have developed, and are unable or unwilling to adopt new business practices. This causes problems because the network effect of the Internet allows issues to evolve much faster than management are traditionally conditioned to react to.
The Internet can destroy entire market sectors. For example, the local travel agency sector has been severely affected by the availability of online booking facilities, which have enabled airlines and hotels to easily do business direct with their customers. AMERICAN EXPRESS COMPANY
is an example of a major travel agency that has seen demand for their travel-related services decrease as more consumers and businesses rely on online travel portals.
