Lock down a mailbox with safe-sender filtering

Objective 4.5 · email security & gateway Objective 2.4 · malicious activity Objective 5.6 · phishing awareness

You are the security analyst at Cedarline Mutual, a regional insurer. The operations lead, Priya Raman, keeps getting buried in spam and the occasional booby-trapped attachment. She has already built a trusted contact list and now wants her mailbox locked to it.

In the Larkspur Mail Safety Center on the left, configure her account so that:

• only people on her Safe Senders list reach the inbox, • blocked junk is reported to the mail provider, and • attachments are accepted only from Safe Senders.

Then answer the three review questions, enter a hacker name, and submit.
