What Exactly is FIPS?
Federal Information Processing Standards (FIPS) are national specifications for computer systems used by military and civilian government contractors.
To approve cryptographic modules, the federal government uses the security standard known as FIPS 140-2. Chef Automate uses the OpenSSL FIPS Object Module, which complies with FIPS 140-2's specifications for software cryptography modules. The OpenSSL Object Module provides an API for calling FIPS-approved cryptographic functions from calling apps.
Who Must Enable FIPS?
If you work for or with a non-military government agency in the United States, you might be compelled by law to activate FIPS. Ask your compliance department if you're unsure whether you need to enable FIPS.
Who Should Not Enable FIPS?
Suppose you work for a US non-military government agency or are under contract with one, and you are required by your agreement to adhere to federal government security standards. In that case, you will just need to activate FIPS. Do not enable FIPS if you are not a US non-military governmental agency or if you do not have a contract with one, and you are not required by your agreement to adhere to federal government security standards. We only advise using FIPS if it is legally required because Chef products have strong security standards even without it. FIPS limits the usage of several hashing techniques you might want to employ.
How to Make the Operating System Support FIPS Mode
Kernel settings for FIPS
A kernel-level setting can set up FIPS mode on Windows and Red Hat Enterprise Linux. The operating system will only employ FIPS-approved algorithms and keys during operation once FIPS mode has been enabled at the kernel level.
Except for the workstation, which necessitates selecting a port in the fips_git_port port option of the cli.toml, all of the tools Chef provides that have FIPS support read this kernel setting and default their mode of operation to match it. For the other Chef Infra tools, such as the Chef Infra Client, if you run it on an operating system set to FIPS mode and the user doesn't disable it, Chef Infra will run automatically in FIPS mode.
How to Set the Chef Infra Server to FIPS Mode
Prerequisites
Systems that are Supported: CentOS or Red Hat Enterprise Linux 6 or higher
at least version 12.13 of the Chef Infra Server
Configuration
If you install or adjust the Chef Infra Server while FIPS compliance is enabled at the kernel level, it will run in FIPS mode by default.
Add fips true to the /etc/opscode/chef-server.rb file to manually enable FIPS on the Chef Infra Server.
How to Make the Chef Infra Client Use FIPS Mode
Prerequisites
Supported Operating Systems: Red Hat Enterprise Linux 6 or later, CentOS, Oracle Linux, and Ubuntu systems with Chef Infra Client 16.13 or later.
Configuration
Chef Infra Client will, by default, execute in FIPS mode if FIPS compliance is enabled at the kernel level. If not, add fips true to either/etc/chef/client.rb or C:\\chef\\client.rb
Frequently Asked Questions
What exactly is Chef infrastructure?
A potent agent, the Chef Infra Client applies your configurations to distant Linux, macOS, Windows, and cloud-based systems. It handles the challenging task of system configuration and enables you to scale Chef up or down as necessary.
What is the purpose of Chef infra?
A potent automation platform called Chef Infra turns infrastructure into code. Regardless of the size of your network, Chef Infra automates the configuration, deployment, and management of infrastructure across it, whether you're operating in the cloud, on-premises, or in a hybrid environment.
Is chef a code for infrastructure?
Infrastructure can be defined as code using the automation tool chef.
Is the DevOps tool chef?
A tool for quickening the delivery of applications and DevOps collaboration is Chef DevOps. By treating infrastructure like code, Chef aids in problem-solving.
How can I send the Frontend node's (Automate or ChefInfraServer) specific configuration?
When creating a file, use the syntax config_file=/ABSOLUTE_PATH/customconfig.toml and give it the absolute path.
Conclusion
On top of Ruby, Chef is a thin DSL (domain-specific language). With this method, Chef can offer just the right amount of abstraction to make it simple to reason about your infrastructure. In addition to a stated way to expand that taxonomy using the full power of the Ruby language, Chef contains a built-in taxonomy of all the essential resources one might configure on a system. Chef Infra chose Ruby because it allows you to use the detailed built-in taxonomy and whatever customization your business needs.
