Social engineering attacks-social engineering attacks: in computer security systems, this type of attack is usually the most successful, especially when the security technology is properly implemented and configured. usually, these attacks rely on the faults in human beings. an example of a social engineering attack has a hacker impersonating a network service technician. the serviceman approaches a low-level employee and requests their password for network servicing purposes. when using smartcards instead of passwords, this type of attack is a bit more difficult. most people would not trust an impersonator wishing to have their smartcard and pin for service purposes.logical, physical and trojan horse attacks are often much less successful when security is properly implemented on a network.
