Explanation:
A social engineering attack is the art of convincing people to disclose useful
information such as account names and passwords. This
information is further exploited by a hacker to gain access to a user’s computer or network. This
method involves the ability of people to trick
someone mentally rather than exploiting their technical skills. This type of attack cannot be
prevented by technical measures only. A user
should always distrust a person who asks him for his account name or password, computer name, IP
address, employee ID, or other
information that can be misused.
