For security teams scrambling to secure their organizations against Log4j exploitation, one of the first and most challenging tasks is understanding where Log4j exists within their environment.
Still, even missing one vulnerable instance of Log4j can leave an organization at risk, which is why discovery is one of the most important steps in the remediation process.
Below are four easy-to-implement vulnerability discovery strategies that can be used to assess an environment for vulnerable Log4j implementations.
The open-source nature of Log4j can also prove useful in the discovery stage.
Security teams can easily download Log4j and create an inventory of all the files that are used by the package, and from there target files that are unique to Log4j.
Security teams must communicate with vendors to determine Log4j's relation to external applications, determine which vendors and services leverage Log4j, whether those organizations have taken the necessary steps for discovery and remediation, and whether they've tested their networks for successful exploitation or instructions.
