What is Security Technical Implementation Guide (STIG)?

A Security Technical Implementation Guide (STIG) is a cybersecurity configuration standard for United States Department of Defense (DoD) information systems and software. STIGs provide a methodology for standardizing security protocols within the DoD, by offering detailed guidance on how to implement security policies and procedures. These guides are developed and maintained by the Defense Information Systems Agency (DISA) and cover a wide range of technologies, including operating systems, applications, and network devices. STIGs are commonly used to harden systems, reducing their vulnerability to cyberattacks. They specify configuration settings and security requirements that help ensure a consistent and secure baseline across an organization's IT infrastructure.
