Thanks to a focus by Apple on People Not Like Me, I was able to get up and running really quickly on my new laptop. The Migration Assistant worked perfectly except for not copying over some saved game files for a Steam game that I play quite a bit (Football Manager 2016). Especially when I have a setup that requires the use of SSH keys and applications all configured to my liking, this was awesome.
My next thought turned to security. Clearly we are in a era where attempts to access people's computers is on the rise. Not that I am thinking I am the target of a shady cabal of l33t hax0rs being paid by shadowy security forces of governments that don't like my politics, but I want to at least make them work a bit. So I want to share what I decided to do.
I've been using FileVault for a long time (in fact, it was a requirement for me if I wished to use my own equipment while working for Mozilla).
After that, you have all sorts of options. After seeing a Tweet from someone mentioning a bunch of tools that can help increase the security of your laptop I decided to take the plunge.
First, I installed Little Snitch. It monitors all my network connections and provides me with a bunch of options to allow or deny the connection, forever or just for a limited time. Starting with this tool I had to (and still are, to a minor extent) acknowledge and decide what to do about a ridiculous number of connection attempts by all sorts of programs. For the older crowd, I feel like I am playing some new version of Everquest. So. Much. Furious. Clicking.
Not content to develop repetitive stress injuries to my right hand, I installed Little Flocker. It's a good complement to Little Snitch -- it watches for any interactions with files, looks for keystroke loggers, and checks for malware. More. Clicking.
Next up was to install Micro Snitch to tell me any time my webcamera and microphones were being used. More alerts to acknowledge but at least my microphone only turns on when I need it to. So far.
Finally I installed BlockBlock to let me know if something keeps trying to install malware in known locations. Just another layer of security for someone to overcome. They clearly indicate that the application is in beta, so keep that in mind.
With those apps installed and running and configured, I massaged my very sore wrist and started reading this awesome document at the suggestion of a kind soul on Twitter. Lots of great stuff in there that you can do and raises interesting points about deciding what type of threats you are looking to protect yourself from. Here's a list of the advice from it that I followed:
- patch everything when updates are available
- frequent system backups (shoutout to Backblaze)
- full-volume encryption
- third-party firewalls
- Disable Spotlight Suggestions
- Use Homebrew
- turn off captive portal
- use Privoxy as a local web proxy
I plan on implementing some of the other recommendations, but that's what I started with. For Mac users, please read through that document. So much good stuff along with explanations of why you should do it.
Hope that helps!
UPDATE February 1, 2018
I received two emails recently pointing out a few things about the tools above.
The first was that the company that sponsors the work of Privoxy has a link on their web site to some very sketchy financial trading software. The person who informed me of this was trying to get me to link to a free VPN solution they were promoting. My personal view is that people running free VPN's are sniffing the hell out of your traffic selling what you're are doing to someone. Make the decision to use a free VPN service with your eyes wide open.
Secondly, I used to recommend the dnsmasq/DNSSEC/DNSCrypt combo but DNSCrypt is no longer available, so I suggest you look for some other tools for encrypting your DNS traffic. The person who emailed me about DNSCrypt pointed to a blog post they wrote about about DNSCrypt alternatives. Either way, encrypting your DNS is a good idea so please consider it.
