Social engineering involves interpersonal influences aimed at eliciting specific behaviors from individuals, such as disclosing confidential information or financial resources. It exploits trust and emotions through techniques like phishing and identity theft, often leading to compromised security. The document includes a fictional dialogue illustrating how a social engineer might manipulate someone into changing a system password.

16. “Hi there, this is Dave Simpson calling from information services at the main branch.
Sorry about the echo, I’m working in the cabling closet at the moment, so I’m
calling you on my cell phone.”
“No problem, I can hear you fine.What can I do for you?”
“Thanks. A lot of the branches have been having network problems over the last
few days. Has everything been okay at the Seashore Branch reference desk?”
“I think so.”
“Okay, that’s good. I’m running a test right now on the network and needed to find
a terminal that was behaving itself. Could you log off and let me know if any
messages come up?”
“No problem.” Marcy logs off of the reference computer;
nothing strange happens.“Just the usual messages.”
“Good. Now start logging back on. What user are you going in as? I mean which
login name are you using?”
“Searef. Okay, I’m logged on now.”
“No strange messages?” “Nothing.”
“That’s great. Look, our problem might be kids hacking into the system so I need
you to change the password. Do you know how to do that?”
“I think so.”

17. “Well, let me walk you through it.” Dave spends a couple of minutes walking Marcy
through changing the system password. The password is now changed to 5eaR3f, a
moderately secure password. “Thanks, Marcy. You’ve been a great help. We have
your new password logged into the system. Could you pass on the new password to
the other reference personnel?”
“Sure.”
“Wonderful. Just remember not to give the password out to anyone who doesn’t
need it, and don’t write it down where anyone who shouldn’t have it can get at it.
Have a great day.”
“You too.”
