Internet security is becoming an increasingly important topic. It’s easy to see why, with high-profile hacks and an ever-increasing trend in data collection. Your information has never been exposed to such risk. The increasing use of technology in everyday security is also changing how law enforcement works.
Other than a good password policy and keeping track of obvious scammers, what can you do to protect yourself? Learning more about how information and technology security works is a significant step.
These DIY projects using the Raspberry Pi are the perfect place to start.
1. Kali Linux: Security OS
Kali Linux is also available for ARM systems like the Raspberry Pi and is easy to install. The OS has several specialized tools for the practical study of information security issues. In addition, the portability of the Pi makes it a desirable device for professional penetration testers.
However, if you don’t know your local laws very well, I would keep looking into your home network!
2. CIRClean: USB Sanitizer
CIRClean (also known as «Kittengroomer», a much better name) is a project designed to protect both people and information. It aims to solve several problems for journalists in some parts of the world, as outlined in an interview with the official Raspberry Pi blog:
- “We need to securely extract information from the USB key without plugging it into any computer we ever want to use again.
- You need a «locked» (not connected to the network) machine in case it tries to talk about you with a weapon
- The second laptop is impractical and raises too many questions
- Virtual machines require the ability to use them (and people are stupid/lazy)
- Virtual machines expose the host machine to whatever is plugged in anyway.”
The answer to all these problems? A dedicated secure OS image designed to perform only one task. Safely transfer information from a potentially infected USB drive to a clean and secure USB drive without transferring malware or alerting anyone to the transfer.
The project is also the perfect way to safely read the contents of potentially dangerous old USB sticks you haven’t looked at since university!
3. PoisonTap: Evil Pi Zero
PoisonTap is an invention of American privacy and security researcher Samy Kamkar. Using only the Raspberry Pi Zero, PoisonTap can infiltrate any computer, even if it is locked or password protected.
Powered by a USB port, it emulates an Ethernet over USB connection before capturing all internet traffic. As if that weren’t enough, PoisonTap installs a permanent backdoor on the system, allowing a hacker to retain access long after the Pi is turned off. By injecting attack code into an open browser, PoisonTap hijacks over a million websites, inserts false frames, and steals data about every web request a user has made since.
4. Make the Ultimate Honeypot
A honeypot emulates a vulnerability in a program or network in order to attract an outside attack. SNARE ( S uper N ext generations, improved effective honpot) and TANNER work in tandem to attract and evaluate potential hacking attempts.
