Chapter 8: Certificate Services on Linux

In this chapter, we'll cover several topics that involve using certificates in securing or encrypting traffic, and in particular configuring and using various Certificate Authority (CA) servers in Linux.

We'll cover the basics of how these certificates can be used, and then progress on to building a certificate server. Finally, we'll look at security considerations around certificate services, both in protecting CA infrastructures and using Certificate Transparency (CT) to enforce the trust model, and for inventory/audit or reconnaissance within an organization.

In this chapter, we'll cover the following topics:

• What are certificates?
• Acquiring a certificate
• Using a certificate—web server example
• Building a private Certificate Authority
• Securing your Certificate Authority infrastructure
• Certificate Transparency
• Certificate automation and the Automated Certificate Management Environment...
