It seems like hardly a week goes by without a high-profile computer breach. Why do these happen? How can you prevent them? This course doesn’t have all the answers, but it does outline practices that make life harder for attackers and that will help tide you over until you get a full-time security team in place.

In this course, you will learn 5 simple, yet effective, techniques for preventing attackers from getting into your system. These techniques are related to: patching, software vulnerabilities, cryptography, windows security, and phishing. Within each chapter you will learn the best practices for preventing vulnerabilities and how to make them more detectable. 

This course is based on the Pragmatic Programmers’ book, Practical Security, and is aimed at developers, admins, team leads, architects, technology generalists, and all others who stand guard against the things that disrupt the network.

Practical Security: Simple Practices for Defending Your Systems

# Introduction
Now that we know all of the libraries we’re dependent on in our codebase, we need to take an inventory of all the networked software that’s running on our network. All the reasons we had for needing a library inventory apply here. Ideally, every server and piece of networked software on your network is already inventoried and automatically patched. It is likely, however, that the team responsible for this (maybe you!) is overworked and doesn’t keep an updated list of everything that’s been deployed.

# Tools
A lot of tools can help you with this task. Some of these tools are commercial and some are open source. The important thing isn’t the exact tool(s) that you use for this job. The important thing is that you find tools that you’re comfortable with and that you can bring into your workflow. In the interest of accessibility—and to keep the examples within everyone’s budget—we’ll look at an open-source tool.

There’s a second reason we start with an open-source–scanning tool. If you don’t have a diligent patching program in place already, you don’t need to spend big money on a commercial scanning tool. Instead, you can put a Post-it on your mirror that reads, “You are vulnerable because your software is out-of-date,” send me a check for $10,000, and pocket the difference. Jokes aside, those scanning tools have their place; but if you don’t have a patching process in place, rest assured that you have vulnerabilities everywhere.
