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

# Explanation
Let’s take a look at what makes up this SQL statement.

- Our statement starts with the SQL keyword `SELECT`. Select statements are the SQL way of querying a database for data. 
- Next, we have `Body`. This part of the select statement tells the database what data to bring back. Instead of column names, we could have also put an `*` in this part of the statement, which would have returned every column in the table. 
- After that, we have the `FROM` keyword. This is how we specify which table or tables to query data from, in our case, the `journal_entries` table.

In the next lesson, we'll look at some more SQL commands.
