An executive shares their inbox

A global stock exchange recently hosted some uninvited guests who quietly browsed a senior executive's email account for nearly five months without anyone noticing. This marathon espionage session graciously allowed hackers to trickle out sensitive data while the C-suite remained blissfully unaware. To defend our own networks from such prolonged hospitality, we must deploy aggressive session monitoring and force multifactor authentication onto our pampered leaders. We cannot simply trust that our highly paid executives will notice when their accounts are suddenly sharing everything with foreign servers.
