Don't forget a privacy filter for the screen. Amazing how much information you can glean just from shoulder surfing.

I'm always amazed to see New York City banks with employees sitting at street-level, and computer screens in-view of the sidewalk. Simply parking a car outside their office with a powerful video camera aimed at their screen must be able to yield something of value.

privacy filter is v useful, but technically doesn't prevent shoulder surfing if someone is looking at your keyboard for your password

Can't speak for other OSes but OS X constantly phones home to Cupertino, sometimes not even using encryption, thus leaking data when you're booked into a public Wifi. I literally spent weeks last year grepping the entire Mavericks base installation for hardcoded URLs, domain names and IP addresses and setting up entries in /etc/hosts and NAT rules to hardwire that stuff to 127.0.0.1. I also had to disable lots of Lau…

I think using little snitch or similar would be the better way to go. Since I imagine not every url is hard coded as plain text and there are updates all the time, and changes and caches ....

But I definitely agree, OS X phones home (and other places) all the time. Everytime my phone rings my mac tries to connect to some apple server. ...

Apple locks in IOS developers to OSX - I'm not aware of any practical way of building IOS apps and submitting them to the app store without running OSX. That doesn't mean you need to use it as your regular personal use OS, but if you're spending your days writing IOS apps you don't have any other choice.

Some others have provided their inputs, my one is just short: take your devices with you, all the time. Yes, that includes the quick toilet break at starbucks. I can't remember how many times I heard total strangers asking around "can you look after my stuff quickly?". You can do that for your beach towel, but not for your devices.

Provided that you lock your device before you leave, have the disk encrypted and do regular backups, what's the problem here?

Lots of other attack vectors left wide open, remember Thunderstrike?

On OS X 10.10 there are no WiFi credentials in the EFI boot variables.

They're also (arguably inappropriately) broadcasting that you passed some sort of bizarre, arbitrary profiling heuristic.

I agree with the above post--I can't even count all the times I've seen people bring in a corporate laptop (complete with an asset tag and call if lost sticker--that's just begging for theft attention) at a public coffee house left unattended. If you are going to bother using a VPN 2-factor token and privacy screen, please keep your laptop in your custody and view at all times. Ideally, work from a private executive…

re: "asset tag and call if lost sticker". I think it's also a great idea to not have your user and hostname set to be "johnbigbucks@bestinvestconsulting" but something more generic or randomized. I use something like this to randomize my hostname. awk 'length==6' /usr/share/dict/words | grep -v '[^[:alpha:]]' | shuf -n 1 | tr '[:upper:]' '[:lower:]'

because i'm somehow compelled to golf such things (like unnecessary use of cat):

    egrep '^[[:alpha:]]{6}$' /usr/share/dict/words | shuf -n 1 | tr A-Z a-z

I don't particularly have any security measures other than a secure password, full disk encryption and locking the screen after a few minutes. If you are taking a device outside of the office (e.g. to take home to work over the weekend) you should be using those anyway. Pretty much all the services (even internal systems for staff only) I interact with are available publicly and have HTTPS, so using a VPN isn't reall…

> using a VPN isn't really going to change much I disagree, using a VPN on open wifi protects against HTTP downgrade attacks, weak cypher compromise, replay attacks... HTTPS for most sites is just not as secure as it should be. It also masks your traffic so outsiders can't even see what servers you are accessing, or how. Wrapping the traffic in a VPN and securing access to your internal assets to office and VPN IPs o…

If your company uses any sort of publicly available web applications you support, please for the love of all the bits use HSTS and submit the domain to the HSTS preload list.

As an Android dev who was forced to create my app for IOS because a huge chunk of users are on IOS, the whole process of developing for IOS gave me brain cancer.

XCode (like itunes) is a worthless piece of garbage. It's unfucking unbelievable how little this "IDE" accomplishes. And uploading to app store (with certificates, provisioning profiles, launch images, icons etc) sucked all the brain juice out of me.

The error messages are even much more cryptic than Windows 95. Why on earth is this piece of locked up abomination so popular? Why are we crying about freedom from government so much and then rushing to buy this crapware?
