EDIT: The original developer apparently has abandoned OpenSnitch, however there is a forked version that as of 2021 is still being actively developed. In addition, there is a newer project by a completely different developer called eBPFSnitch. For more information on the forked version, see OpenSnitch Linux Application Firewall Fork With Improvements And Bug Fixes (LinuxUprising)
Previously we covered KeePassXC password manager which is also free application. Here comes another password manager called Enpass, it is free and cross-platform available for Linux, Windows, Mac, Android, Blackberry, Windows Phone and iOS.

Online privacy and security are constantly under assault. It seems like every day there’s a new threat to your personal information. Choosing and configuring the right web browser goes a long way in protecting yourself. Right now Firefox is the best option for that. It’s open source, gives you tons of options for control, and has all of the privacy and security add-ons you’ll need.
This guide is as complete as it can be at the time of writing. These are ever-evolving topics, and threats continue to change. Regardless, this guide will give you a good basis to protect yourself from common threats.
With the amount of malware currently prowling the internet it’s becoming increasingly important to protect your computer. Therefore I’ve separated my advice on how to stay safe online into two main sections. The first is the methods that I believe anyone from a novice to an expert user can use. The other section is aimed more at intermediate to advanced users. These methods may be more difficult to use, but your computer will be more secure.
When you want to send an instant message to someone else that’s on the same local network as you are, whether that be another family member or a co-worker in your office, why use an offsite chat server that leaves your messages open to interception by the company running the chat server or some other third party? This software will allow you to keep your local IM’s in your local network, and for added safety it also encrypts them! Plus, it supports multiple operating systems, unlike the proprietary chat client that might have come with your computer. It’s NOT for chatting with people elsewhere on the internet; if you need to set up secure connections with offsite chat clients then you may need to set up a private Prosody IM server. But for secure IM chats with people on your local network, this looks like just the thing!

In the previous post, we’ve talked about how to Secure Linux Server Using Hardening Best Practices and some people ask me about firewall section which was a brief introduction about iptables firewall. Today we will discuss in detail the Linux iptables firewall and how to secure our servers traffic using that awesome tool.
Though Mac users don’t usually have to worry excessively about “camfecting” malware and spyware, some security conscious users may find it nice to know if a process or application is attempting to access their computers web camera or microphone.
A couple redditors showed interest in how I set up my Pi as a SOCKS proxy and recommended I make a separate post as a tutorial, so I’ll do my best to explain everything.
SOCKS stands for Socket Secure, and is essentially just a middle man for a server and client for send information between. The best description I’ve heard of it is “It’s a poor man’s VPN.” It essentially works the same, but each service has to be configured to work with it (i.e. I have Firefox on my Mac working through my SOCKS proxy but not Chrome and Safari). Why would you want a SOCKS proxy over a VPN? From my experience, it runs better on a Pi, and I can also do multiple things over SSH (such as also run a file server). Having to configure each service to run through it can also be a pro or a con, depending on if you want everything to work through it or not.
There’s really not much to setting everything up; it’s a pretty straightforward process. For those just looking for something short and sweet, here are the basic steps I followed. I’ll go over each more in depth below.

A decade ago, if a desktop computer got infected with malware the chief symptom probably was an intrusive browser toolbar of some kind. Five years ago you were more likely to get whacked by a banking trojan that stole all your passwords and credit card numbers. These days if your mobile or desktop computer is infected what gets installed is likely to be “ransomware” — malicious software that locks your most prized documents, songs and pictures with strong encryption and then requires you to pay for a key to unlock the files.
Here’s some basic advice about where to go, what to do — and what not to do — when you or someone you know gets hit with ransomware.
