A best practice in security is alerting on the assets that you find most critical. The concept of vulnerability and exploit defines that a vulnerability can be exploited.   

The Prisma Cloud product from Palo Alto Networks has a number of threat landscape views along with preventative tools to help mitigate the risks of a vulnerability, including zero-day vulnerabilities.   We will examine how Prisma Cloud can notify you of a CVE, what API calls can be used to find the resources affected by a CVE, and how to create a custom CVE to support zero-day vulnerabilities. This article will demonstrate how you as a security professional can get a better understanding around the threat landscape of your environment.  For purposes of example, we will use Log4J as our zero-day threat in this article.
