Smart home devices can be really cool and convenient, but are you using them safely and securely?

The latest SANS OUCH! newsletter is out: Smart Home Devices. This page is a great resource for #OPSEC information you can share with your work force and their families.


For those DON members with access to Navy e-Learning, Uncle Sam’s OPSEC v.3 is now available. Expect to see it on the updated App this Fall.

You are responsible for safeguarding classified, proprietary, protected, and sensitive information. Ask yourself if the individual has a legitimate need for the information to perform his or her job, and does the individual possess the appropriate clearance and access. Share responsibly and abide by the Need to Know principle.


Anyone with access to classified, proprietary, protected, or sensitive information can be a target of elicitation. The adversary is skilled in discretely gathering information from seemingly innocent conversations. Not everyone has the best intentions. Limit what you share. Never divulge sensitive or protected information in an unofficial capacity.


When traveling with the family this spring break, wait until you return to post about your vacation. You don't want everyone to know exactly where you are, or maybe more importantly, where you are not! You don't want a potential thief to know your house is vacant for several days!

This is how hackers hack you using simple social engineering

Social engineering is a huge OPSEC vulnerability. What is social engineering? Simply put, it is the art of psychologically manipulating people into divulging sensitive or classified information. To avoid being socially engineered, don't open emails or attachments from suspicious sources, use multifactor authentication on accounts, be wary of tempting offers, and keep antivirus/antimalware updated. Watch how easy it is to be socially engineered!
