What is Terrascan?

It is an open-source static code analysis tool. It is used to scan the templates in IaC and cross-check them with the in-built policies defining the structure of a good IaC. It is good for beginners trying to learn how to build IaC in the cloud, AWS, Azure, and GCP.

It provides you with a good blueprint on how to build infrastructure native to the cloud. In cloud computing, it is nearly impossible to remember almost all of the policies (there are over 500). With Terrascan, developers can check if their code matches policy standards and need not remember all the IaC policies in the cloud. It can be used to analyze and scan code in Terraform similar to other tools used for Terraform. There are various Terraform tools available. But, why do you need to use Terrascan? What are its benefits? The features of Terrascan will be discussed in detail.

Terrascan is a popular software used to detect any possible vulnerabilities in IaC (Infrastructure as Code) structures. With its predefined built-in policies, Terrascan can detect any vulnerabilities in your code and let you know about the policy violations in detail, including their severity. The violations can range from minor infractions to severe structural compromises detected in the code. Before we go into detail, let’s see more about Terrascan.
