Intro to Security

Educating others on how to stay safe online and
make the world a safer place
Hacks are becoming common news stories, so knowing how to protect yourself online is more important than ever.

This site has two aims:
  1. Basic Topics: Educate the public on basic online security practices
  2. Advanced Topics: Provide information and tutorials for those interested in careers in cybersecurity

Technology has become ubiquitous in today's world and will be even more so in the years ahead. While it has made life better in so many ways, it has created new risks that range from petty annoyances to financial ruin. And it now has the potential to physically harm or even kill - through cyberweapons, the Internet of Things (IoT), and self-driving cars.

These aren't reasons to abandon technology, though. Ultimately, the impact of technology now and in the future comes down to how we choose use it (for instance, right now you could text a friend who's going through a hard time, or you could humiliate them on social media).

Unfortunately, there will always be people who misuse and abuse technology. Consequently, each of us needs to make decisions on a daily basis as to how much risk we want to expose ourselves to; and because some of these problems are too large for any one individual or company to handle, we'll need to be active and knowledgeable participants in public debates as new government regulations are likely to be enacted.

In order to appropriately assess risks, stay protected, and participate in debates as an informed citizen, each person needs to understand what risks are out there, why those risks exist, and cultivate a security mindset (at least at a basic level).

It should be noted, though, that a complication arises in cybersecurity with how we assess how secure we are. Just because we feel safe (e.g., when Chrome displays a green lock next to the URL) doesn't mean that we actually are safe. This is completely different from how humans have assessed risk throughout human history. Generally speaking, if we felt safe, then we were safe (e.g., we live in an area with low crime rates and no one's broken our windows, so we feel and are safe). This oddity with cybersecurity has given rise to security theater, which is where policies are enacted to increase security (and make us feel more secure) but don't actually achieve that goal. Regrettably, security theater is performed by many organizations, including the TSA.

Because of this reality, we can't just change a few settings and feel completely safe. Our biggest hope is that this site will help you develop a security mindset. However, each person is comfortable with different levels of risk in their life, so I'm not going to say, "You must absolutely do this or else..." Rather, we'll talk about various risks, their consequences, and solutions to lessen those risks. You can then decide what you want to do. Will there be principles that we highly recommend you practice? Of course. But we also understand that you may be comfortable with more risk than we are. Ultimately, we want you to act knowing the landscape rather than making decisions blindly.

Listed below are topics that will help you be safer, better informed, and create a security mindset.

Note: Nothing and no one can ever be 100% secure. If somone or a product claims to offer 100% security, they're intentionally misleading you, incompetent, or maybe a bit of both. While forming good habits will lower your chances of becoming a victim, we live in a connected world, and your information can still be compromised if other entities don't secure their systems or protect your personal data.

What This Site is Not

This site does not cover every security topic, nor does it teach you how to hack. There are so many subjects and angles to approach security from that, even at an introductory level, an exhaustive discussion on this site isn't feasible.


Technology is everywhere and has brought opportunities and risks. This site helps you develop a security mindset so you can be safer online and an informed citizen. It does not teach you how to hack.
