A user receives a call from someone claiming to be a technical support agent. The caller asks the user to log in to the computer. Which of the following security measures should the user take to…

Only accepting calls from known people or verifying the identity of unsolicited callers through official channels is a fundamental security measure against social engineering attacks like tech support scams. This prevents attackers from gaining unauthorized access to systems or information by impersonating trusted entities.

Disregarding suspicious emails is a good practice, but it's irrelevant to a phone call scam scenario.

Updating antivirus software is a technical control against malware, not a direct measure to handle unsolicited phone calls from scammers.

Enabling two-factor authentication enhances login security, but it doesn't prevent a user from being tricked into granting remote access or divulging information over the phone.

Installing a malware scanner is a technical control against malware, not a direct measure to handle unsolicited phone calls from scammers.
