Security with Go

By: John Daniel Leon

Overview of this book

Go is becoming more and more popular as a language for security experts. Its wide use in server and cloud environments, its speed and ease of use, and its evident capabilities for data analysis, have made it a prime choice for developers who need to think about security. Security with Go is the first Golang security book, and it is useful for both blue team and red team applications. With this book, you will learn how to write secure software, monitor your systems, secure your data, attack systems, and extract information. Defensive topics include cryptography, forensics, packet capturing, and building secure web applications. Offensive topics include brute force, port scanning, packet injection, web scraping, social engineering, and post exploitation techniques.

Summary

After reading this chapter, you should now understand how to use the Go SSH client to connect and authenticate using a password or a private key. In addition, you should now understand how to execute a command on a remote server or how to begin an interactive session.

How would you apply an SSH client programmatically? Can you think of any use cases? Do you manage multiple remote servers? Could you automate any tasks?

The SSH package also contains types and functions for creating an SSH server, but we have not covered them in this book. Read more about creating an SSH server at https://godoc.org/golang.org/x/crypto/ssh#NewServerConn and more about the SSH package overall at https://godoc.org/golang.org/x/crypto/ssh.

In the next chapter, we'll look at brute force attacks, where passwords are guessed until eventually a correct password is found. Brute forcing is something...
