AppLocker, Application Control, and Code Signing

In an enterprise environment, it is critical to keep control over what software is installed and what software is being kept out of the environment – not only to keep an overview of what software is available but also to help fight against threats such as malicious scripts or malware such as ransomware.

But how can code signing and application control help you secure your environment in a better way and how can it be implemented? What do you need to do when planning for implementing an application control solution and what built-in application control solutions are available on Windows operating systems?

We’ll explore this and much more in this chapter about AppLocker, application control, and code signing. In this chapter, you will get a deeper understanding of the following topics:

  • Preventing unauthorized script execution with code signing
  • Controlling applications and scripts
  • Getting familiar with...
