The Principles of “LifeSec”
Trigger warning racism, stupidity
If you wanted to end your career in a hurry, it would be hard to beat the example of Justine Sacco. As the communications director for a large company, you'd think she'd know better than to drop this tweet just before hopping on a plane for a business trip:

For the 11 hour duration of her flight, the tweet spiraled further and further into cyberspace while people expressed outrage or gleefully waited to see her panic when she stepped off the plane to thousands upon thousands of posts under the hashtag #HasJustineLandedYet.


No matter how tired or addled we are, most of us would never post something like this and, even if we did, the odds of going viral are still pretty low.
It might go unnoticed entirely or, once you came to your senses, you might be able to edit/delete it or even intentionally obscure it to make it harder to find. But those are under very specific conditions that mostly depend on you acting before it's noticed.
That's why your best defense is not repair, it's prevention. And that means, before you post, ask:
- What if the people I love see this?
- What if people who hate me see this?
- What if this goes viral? What if the news picks it up and every hater in the world see's this?
- When I'm dating or job-hunting in the future and they dig this up, am I ok with that?
Hoping that something won't spread further than you expected is a risk. Better to assume the worst before hitting the "post" button.
![]() | ![]() | Is it possible what you post will never spread further than you intended? Sure. Is it possible to remove information before it's noticed or make it harder to find? Sure! But that's never guaranteed and isn't worth the risk. If you're not comfortable with something being visible to everyone, everywhere, forever, reconsider posting. |

Where are you from?
When you're traveling and someone asks, "where are you from?" What do you say? Do you give them an address? Street directions? Turn-by-turn steps to reach your front door? I'd bet not.
Not that you have to be silent or rude, but conversation doesn't demand highly specific details nor does your conversation partner usually care! For your benefit and theirs, always ask, what is the least amount of information I can give?"
![]() | ![]() | Don't underestimate the double-win of becoming more safe AND becoming a better conversationalist by learning to omit needless details! |
In my case, I live in the Seattle area. That means if I'm overseas, I say "American". If I'm someplace in the US, but exotic like Hawaii or Oregon, I say, "Washington". And if someone in Washington asks, I say "Seattle Area".
There will be times you make a judgement call that people are safe enough to share more details even down to the neighborhood – people at work, the other parents at the sports match, etc., but that's the exception. On average, be only as specific as necessary.
![]() | ![]() | Pro tip! Your phone's map tool doesn't need to know where you live either. When setting your 'home' location, set it to somewhere in your neighborhood instead. Then, if your phone is hacked, lost, or your data is sold, you didn't paint a target directly on your house. |
What about your family?

Every time you're tempted to write information about your family, pause. Is it really necessary to list their names ever? Not that I've ever seen.
Instead, why not just say "my wife", "my kids" (assuming there's a reason to bring them up at all). Instead of age, "baby", "young", "teens", and "adult" are specific enough. Why list genders? Why be specific about how many? "I'm a parent" is good enough and if you feel the need to number them, say "I have a few/bunch/plethora" etc.
Are you or someone you love LGBTQ+? Faced self-harm? A psychotic break? Rehab? Had a religious conversion? Things that might be sensitive if other people knew? You should share sparingly (if at all) and as generally as possible.
I might mention that my LGBTQ+ friends and family were the motivation for writing this guide because that's relevant to the content, but you'll notice I don't say who nor list age, gender, or anything else specific because none of that is necessary. And even if it is, I often randomize genders, ages, and other details (while staying in the general ball park) when the precise information doesn't matter.
Focus on what is being asked and why and then answer the minimum. Whatever is close enough. For example, when asked for your birthday, it's rare that they actually need your birthday. Usually it's for age verification (in which case, any date that's about your age will work) or for an annual free coffee or cookie at your favorite cafe (again, any date will work).
![]() | ![]() | In the few cases where someone pries uncomfortably, try asking, 'why do you want to know?' Maybe there's a valid reason you don't know about, but otherwise, it's best not to give more information than is necessary. |
Have you heard of doxing? Most people focus on the public release part, but the key is that they had a dossier of information to release in the first place. Where did they get it?
Generally, Doxers simply dig and combine from public data online – stuff that was carelessly left in the open or that people didn't think was a risk in isolation – but what happens when it doesn't stay isolated?
In the Department of Defense, we were trained to limit "data aggregation risk" – where the combination of details can paint a larger or more precise picture (sometimes even elevating Unclassified information to Classified by aggregation).
That's why should think carefully about playing along with one of those "your birth month is your Hogwart's character!" posts. Rarely (if ever) fill in details in online profiles and social sites. Think carefully about whether you're legally required to even use your real name or birthday.
![]() | ![]() | When supermarkets ask you for a phone number, maybe you could use (your area code) 867-5309 (the 'Jenny' number) instead (555-1212 is a good second). If someone asks for your SSN and you're positive they don't actually have a right/need for it, zeroing out the two middle numbers should make it an invalid number (so you're not harming a stranger by providing it). That said, you're responsible for checking any applicable laws or consequences before taking this advice! |
Little bits of information add up fast so make sure to limit the availability as much as possible. The less detail in the less locations information is, the harder it is to find and combine.
Whether you are acting on your own capacity or as an ally/activist, arguing with hateful people online is risky. Depending what you say, who you say it to, in what venue, under what circumstance, you could be volunteering to be a bigot's new pet project.
Or maybe you did nothing wrong at all and the bad guys just found a conversation they weren't part of and took exception to something you said in particular. Either way, you're now in the crosshairs.


The bottom line is to be hard to attack. Post generically. Fudge unimportant details. Use fake information (where legal and appropriate). Guard your photos. Deny websites/stores/etc. information they don't strictly need. And carry these principles of data protection with you in real life too.
![]() | ![]() | A lot of ID theft prevention is making sure people don't have your information who don't need it (see my Data Defense articles for more). |
When making conversation, when at the store, filling out a form at the dentist – like a martial art, use the minimum motion and force to get the job done. Use the least information possible at all times and in all ways.
Then, even if someone becomes interested in you for the wrong reasons, if the amount of effort it takes them to harm you exceeds their level of interest/time, you win.
Many years ago, my wife called me and said her friend needed help. "Friend" ("Fren" for short) was trying to build her business on Facebook, but someone was leaving harassing and slanderous comments on all her posts. Fren was pretty sure she knew who it was, but Facebook wouldn't help and the police said there was nothing they could do without an IP address of the perp and my wife thought maybe I could help. She was right.
You see, I had learned about "Social Engineering" – the art of guiding people to giving away information without realizing it. So I set a trap: I wrote a post on this website saying something like "I've been looking at partnering with Fren Industries, but don't know much about them. If ANYONE has any information about them, I'd love to know!".
Next, the lure. I gave Fren the link and told her to post on Facebook something like "Hey, I'm trying to partner with The Geek Professor(R) in my business and I could use some positive reviews! Please head over and leave some (link)".
In mere hours, I had a comment using the same kind of language and same kinds of slander as on the Facebook posts, but on my website where the IP addresses of people who comment is visible. So I provided the IP address and screenshot of the post to Fren and she called the police.
Though in the above example, social engineering was used for good, that's not always the case. Smooth operators are always trying to push people into giving them your data –OR– the data of others. Consider if a stalker sees you talking to their target because you're friends/co-workers/etc. So they ooze up to you with some story about how they "found something" their victim dropped or that they're "good friends from high school" and they really want to catch up!
They'll try to convince you to share the target's phone number, address, or schedule, but there's essentially zero cases where that's an OK thing to do. Instead, you can tell them, "Wow Stalker, you found their thing! Thanks, I'll get it back to them." or "You're friends? That's great! I'm sure they'll be happy to hear from you so leave me your contact information and name and I'll give it to them when I see them next!".
![]() | ![]() | Don't buy into someone's story and hand out someone else's information! Always be a buffer between them - no matter the story, no matter how believable it might be. They might be telling the truth, or they might be your friend's abusive spouse who's tracking them down. |
Similarly:
- Never upload photos of friends, their kids, or anything else without asking first.
- Never "tag" someone by name. If they're good at LifeSec, you might be ruining it by naming them, their spouses, and their kids in your posts.
- Never tell someone else's stories or rants without asking fist. Just because they freely ranted about their boss to you doesn't mean you can share it online.
- Think twice about wishing them a happy birthday on an open feed.
- Definitely don't hint at or talk about non-public information on an open social page (ex. Have you come out to your folks yet?)
- Always think about how much you're actually giving away. Don't ask "I heard your team won last night! Go Eagles!" – A team name and game date might be enough to find your school.
Loose information makes you a target and it makes you an easy target. It's up to you what to share, but do so aware of the consequences and risks. Most importantly, adopt LifeSec principles all the time and it becomes easy to:
- Remember that what goes online, goes everywhere; forever. Don't post anything that you're not willing to have dragged back up and used against you later.
- Learn to be evasive and general. Not only does this make you a better conversationalist, it's safer too!
- Think about how your data can be combined. Don't fall into the trap of thinking "this will be ok because it's just a little bit of information". People and AI can line all the different data up into one clear picture.
- Be a hard target. Don't get discouraged and think there's no point; no matter what the risk might be, if you're more trouble than you're worth to the bad guy, that can be enough!
- Protect others too!. Don't share other people's information either. You might be painting a target on them.
And that's the basics.
![]() | ![]() | If I wasn't clear, this isn't 'do this sometimes', but a way of life. Adopt LifeSec as a way of life and you'll be safer not just online or offline, but all the time. For you, for your loved ones. You become, by nature, a hard target. |
